A Guide to Understanding SEER Ratings for AC Units

Choosing a new air conditioning (AC) system for your Lubbock home requires balancing upfront costs with long-term energy savings. The most critical factor in this decision is the unit's SEER rating. Understanding what this number means will directly impact your utility bills and overall comfort for years to come.

At Nugent Mechanical Contractors, we prioritize guiding our customers through efficiency ratings to ensure they make a smart, informed investment.

What is the SEER Rating?

SEER stands for Seasonal Energy Efficiency Ratio.

In the simplest terms, the SEER rating measures the efficiency of an air conditioner over an entire cooling season. It is calculated by dividing the total cooling output (in BTUs) during a typical cooling season by the total energy input (in Watt-hours) consumed during the same period.

• Higher SEER = Greater Efficiency: A higher SEER number indicates that the unit uses less electricity to produce the same amount of cooling power.

The New Standard: Introducing SEER2

As of January 1, 2023, the Department of Energy (DOE) introduced a new testing standard for AC efficiency called SEER2.

The new SEER2 testing method is designed to better reflect real-world operating conditions, particularly static pressure (airflow resistance), by using more realistic test procedures. Therefore, a unit rated at 14 SEER under the old system might be rated slightly lower, say 13.4 SEER2, under the new system, even though it's the exact same piece of equipment.

The minimum efficiency standard for central AC units in Texas is now 14.3 SEER2.

How SEER2 Translates to Savings

In a climate like Lubbock's, where summers are long and hot, choosing a higher SEER2 rating offers substantial benefits:

• The Investment: While a higher SEER2 unit has a greater upfront cost, the reduction in your monthly utility bills provides a return on investment (ROI) that can pay for the difference over the unit's lifespan.

Why SEER2 Matters in Lubbock

1. Lower Utility Bills: The longer your AC runs, the more the efficiency gap between a 14 SEER2 unit and a 16 or 18 SEER2 unit widens. Given the sustained summer heat in West Texas, investing in high efficiency translates to immediate and substantial monthly savings.

2. Increased Comfort: Higher SEER2 systems often use two-stage or variable-speed compressors, which run for longer periods at lower capacities. This operation not only saves energy but also improves comfort by removing more humidity from the air, making your home feel cooler even when the thermostat setting is slightly higher.

3. Future-Proofing: As energy costs continue to rise, a higher SEER2 unit ensures your home is protected against future utility inflation.

When it's time to replace your unit, don't just ask about the price—ask about the SEER2 rating. Contact Nugent Mechanical Contractors to explore high-efficiency AC options perfectly sized for your home.

Breathe Easier, Save Money: How to Improve Airflow and Efficiency in Your HVAC System

Your heating and air conditioning (HVAC) system is designed to circulate a precise volume of air to heat and cool your Lubbock home efficiently. When airflow is restricted or compromised, your unit has to work harder and run longer, leading to higher energy bills, poor comfort, and premature wear and tear.

At Nugent Mechanical Contractors, we know that improving airflow is one of the quickest ways to boost your system's efficiency. Here are the top ways you can maximize airflow, along with professional steps that can ensure your system is performing at its peak.

DIY Steps: Quick Fixes for Better Airflow

These are simple tasks every homeowner can perform to immediately improve air quality and HVAC efficiency:

1. Change Your Air Filter (Regularly!): This is the single most important step. A dirty, clogged air filter is the number one cause of restricted airflow. It forces the blower motor to work harder, wasting energy and eventually causing the system to overheat or fail. Change your filter every 30 to 90 days during peak usage seasons.

2. Clear Vents and Registers: Check every supply and return vent in your home. Ensure they are fully open and not blocked by furniture, curtains, or rugs. Blocking registers traps conditioned air and disrupts the balance of the whole system.

3. Clean Exterior Unit (Condenser): Your outdoor AC condenser unit pulls air in to release heat. Trim back any shrubs, weeds, or tall grass at least two feet away from the unit to ensure it has proper breathing room. Carefully wash the exterior of the fins with a gentle stream from a garden hose to remove accumulated dirt.

Professional Steps: Maximizing System Efficiency

While DIY fixes help, a professional inspection is required to address deep-seated issues that compromise efficiency.

• Ductwork Inspection and Sealing: In many homes, 20% to 30% of conditioned air is lost through leaks, holes, and poor connections in the ductwork before it ever reaches your living spaces. Our technicians inspect the duct system and seal leaks using specialized mastic sealant or professional-grade metallic tape. Sealing ducts is one of the best ways to improve efficiency.

• Coil Cleaning: Your indoor evaporator coil and outdoor condenser coil accumulate dust, grime, and mold over time. This layer acts as an insulator, severely restricting the system's ability to transfer heat (cooling) or absorb heat (heating). A professional tune-up includes deep cleaning these coils to restore peak performance.

• Blower Motor Inspection: The blower motor is the heart of your airflow system. We check the motor's fan blades for dirt buildup and ensure the motor is lubricated and running at the correct speed (or "static pressure"). Proper motor performance guarantees the right volume of air is delivered to every room.

• Drain Line Clearing: During the summer, the condensate drain line can become clogged with sludge and algae. This backup can restrict airflow and eventually shut down your AC unit entirely. We inspect and clear this line to ensure seamless operation.

Get Your HVAC Checked by the Experts

Don't let poor airflow cost you money and comfort this season. By addressing both the simple DIY fixes and the complex professional issues, you can significantly improve your HVAC system's efficiency and longevity.

Contact Nugent Mechanical Contractors today to schedule your comprehensive system tune-up. We'll ensure every component, from the air filter to the duct connections, is optimized for peak performance and maximum energy savings.

Don't Sweat the Summer: The Importance of AC Maintenance Before Heat Hits

The summer heat in Lubbock is intense, and your air conditioner is your home's biggest defense. Waiting until the first triple-digit day to discover your AC is struggling is a costly mistake. Scheduling professional air conditioner maintenance before summer officially begins is the single most effective way to ensure reliable cooling, maximize efficiency, and protect your budget.

At Nugent Mechanical Contractors, we know that a proactive spring tune-up is the best insurance against a mid-summer breakdown. Here's why this preventative service is non-negotiable.

1. Maximize Efficiency and Lower Energy Bills

Dirt is the number one enemy of cooling efficiency. Over the winter, your outdoor condenser unit accumulates dirt, debris, and grime on its coils and fins.

• Restoring Cooling Power: A professional cleaning removes this insulating layer of filth. This allows the unit to easily transfer heat out of your home, restoring its maximum cooling capacity.

• Preventing Overwork: A dirty system has to run longer and consume more electricity to achieve the same temperature. A clean, calibrated AC runs efficiently, directly translating to lower utility bills throughout the summer.

2. Prevent Catastrophic Mid-Summer Breakdowns

The highest stress on your AC system occurs during the hottest part of the year. A professional tune-up is designed to catch minor issues before they become major, catastrophic failures.

• Safety Check of Electrical Components: We inspect and tighten all electrical connections, check the capacitor (the component that gives your unit the power boost it needs to start), and test the contactors. These are the most common parts to fail during high-demand operation, often leading to a complete system shutdown.

• Refrigerant Level Check: Low refrigerant means the system has a leak. We identify and fix small leaks before they cause the compressor—the heart of your AC—to overheat and fail. Compressor replacement is one of the most expensive repairs an AC owner faces.

3. Protect Your Warranty and System Lifespan

Your AC unit is a significant financial investment, designed to last 15-20 years. Consistent, professional maintenance protects this investment in two key ways:

• Validating the Warranty: Most manufacturer warranties require documented annual maintenance to remain valid. Skipping your spring tune-up can void your coverage, leaving you personally responsible for the full cost of a major parts failure.

• Extending Lifespan: By ensuring all parts are clean, lubricated, and running at optimal capacity, you reduce friction and strain, extending the overall lifespan of your unit.

4. Ensure Healthy Airflow

A spring tune-up addresses the crucial issue of airflow and drainage:

• Filter and Coil Cleaning: We replace the air filter and inspect the indoor evaporator coil. A dirty coil harbors mold and mildew, while a dirty filter restricts airflow, which is terrible for indoor air quality and efficiency.

• Clear Condensate Drain: We inspect and clear the drain line that removes condensation (water) from your system. A clogged drain line can cause water backup, leading to water damage in your home or causing the AC to shut off automatically.

Don't wait for the heat wave to hit. Schedule your professional air conditioner maintenance with Nugent Mechanical Contractors today and enjoy a cool, worry-free summer.

Spring HVAC Tune-Up Checklist: Getting Ready for Lubbock's Summer Heat

After a long winter of unpredictable Texas weather, your heating system is ready for a rest—and your air conditioner is about to get its biggest workout of the year. Preparing your entire HVAC system for the intense Lubbock summer heat is essential for comfort, efficiency, and avoiding emergency breakdowns.

At Nugent Mechanical Contractors, we perform comprehensive spring tune-ups to transition your system smoothly from heating to cooling. Here is a look at what our professional spring maintenance checklist covers and why each step is critical for your home.

Phase 1: Safety and System Diagnostics

Before focusing on cooling, the system must be checked for winter damage and proper function.

• 1. Check for Carbon Monoxide/Gas Leaks: For homes with gas furnaces, we meticulously inspect the heat exchanger for any cracks and check all gas line connections to ensure safety. This is a critical step before switching systems over.

• 2. Test Thermostat Calibration: We verify that your thermostat is accurately reading the temperature and communicating correctly with the HVAC unit. This ensures precise temperature control and prevents unnecessary energy use.

• 3. Inspect Electrical Connections: We check, clean, and tighten all electrical wiring, capacitors, and contactors. Loose connections are a leading cause of system failure and can pose a fire hazard if not secured.

Phase 2: Preparing the Cooling System (Air Conditioner)

This phase focuses entirely on maximizing your AC’s efficiency for the coming summer heat.

• 4. Clean the Condenser Unit: The large outdoor unit, the condenser, pulls heat from your home and releases it outside. Over winter, it accumulates dirt, debris, and grime. We clean the coils and fins to ensure maximum heat transfer capacity, which is vital for efficient cooling.

• 5. Check Refrigerant Levels: The technician measures the refrigerant charge to ensure it matches the manufacturer's specifications. If the level is low, it indicates a leak (a repairable issue) and reduces the system's ability to cool your home.

• 6. Inspect and Clear Condensate Drain Line: The drain line (or condensate line) removes moisture (water) collected during the cooling process. If this line becomes clogged with algae or debris, it can back up, causing water damage and potentially shutting down the AC system entirely.

Phase 3: Optimizing Airflow and Efficiency

A system is only as efficient as its airflow. These steps ensure clean, consistent air delivery.

• 7. Replace Air Filter: A new air filter is non-negotiable. A clean filter improves air quality, protects your expensive internal components from dust damage, and optimizes airflow, all of which save energy.

• 8. Inspect Indoor Evaporator Coil: We check the indoor coil (usually located above the furnace) for dirt and dust buildup. A dirty evaporator coil severely hampers cooling efficiency.

• 9. Inspect Ductwork Seals: We look for any obvious leaks or separation in the accessible ductwork near the air handler. Leaky ducts waste conditioned air into unconditioned spaces (like attics), wasting energy and money.

The Nugent Mechanical Advantage

A professional spring tune-up is the best insurance policy against emergency repairs and excessive utility bills. It ensures your system is safe, efficient, and ready to handle the intense, triple-digit temperatures that are standard for a Lubbock summer.

Don't wait for your AC to struggle. Contact Nugent Mechanical Contractors today to schedule your spring tune-up and keep your comfort guaranteed all season long.

What to Expect During a Professional HVAC Installation

Installing a new heating, ventilation, and air conditioning (HVAC) system is a significant investment in your home's long-term comfort and value. Whether you’re replacing an old, inefficient unit or installing a brand-new system in a new build, knowing what to expect during the process helps ensure a smooth, worry-free experience.

At Nugent Mechanical Contractors in Lubbock, we pride ourselves on transparent communication and meticulous workmanship. Here is a step-by-step guide to what happens during a professional HVAC installation.

Phase 1: Planning and Preparation

The success of your installation hinges on accurate planning. This phase takes place before any physical work begins.

• Load Calculation (Manual J): First, we perform a detailed load calculation (often called a Manual J). This is the most crucial step, determining the exact size (tonnage and BTU) required for your home based on square footage, insulation levels, window type, sun exposure, and local climate. This ensures the new unit is perfectly matched to your home's needs, avoiding the efficiency problems associated with oversized or undersized systems.
• System Selection: Based on the load calculation and your budget, we help you select the right type of equipment—such as a gas furnace and AC, a heat pump, or a ductless mini-split—and discuss efficiency ratings (SEER2/AFUE).
• Permitting and Scheduling: We handle all necessary local permits and finalize the installation schedule with you.

Phase 2: Removal of the Old System

On installation day, the first task is safely and cleanly removing the existing equipment.

• Secure Shut-Offs: The technician will shut off power and gas to the old system. For the air conditioning unit, the refrigerant will be safely recovered using specialized equipment, as refrigerants are harmful to the environment.
• Disassembly and Removal: The old indoor furnace/air handler, outdoor condenser unit, and line sets are carefully disconnected and removed from your property for proper disposal or recycling. We take great care to protect your home's interior and landscape during this process.

Phase 3: Installation of New Components

This is where the new, high-efficiency system is put into place.

• Indoor Unit Installation: The new furnace or air handler is set into its position (attic, closet, or basement). New duct connections are made, ensuring they are properly sealed to prevent air leaks, which can account for significant energy loss.
• Outdoor Unit Installation: The new condenser unit is placed on a level pad outside. We ensure it has proper clearance for airflow and efficient operation.
• New Line Sets and Electrical: New copper refrigerant lines (line sets) are run between the indoor and outdoor units, along with new electrical wiring and drainage lines. Proper sizing and sealing of these lines are vital for efficiency and system performance.
• Safety and Venting: For gas furnaces, we install and inspect the flue (venting pipe) and gas line connections to ensure exhaust gases are safely routed outside and to eliminate the risk of carbon monoxide leakage.

Phase 4: System Startup and Testing

Before the team leaves, meticulous testing ensures everything works perfectly.

• Refrigerant Charge: The correct amount of refrigerant is precisely measured and charged into the system. This step is critical for efficient cooling and is done using accurate gauges and tools.
• System Calibration: The technician calibrates the furnace (checking gas pressure and combustion) and the air conditioner (checking static pressure and temperature differentials).
• Thermostat Installation: The new or smart thermostat is installed and configured to communicate correctly with the new unit.
• Walkthrough and Final Review: We will walk you through the operation of your new HVAC system, explain maintenance requirements (like filter changes), and ensure you understand the warranty. We won't leave until you are completely satisfied with the installation and comfortable using your new system.

Choosing Nugent Mechanical Contractors means choosing quality and peace of mind. Contact us today to start the conversation about your new, high-efficiency HVAC installation.

The Role of a Heat Pump in Keeping Your Home Comfortable

For homeowners in Lubbock, achieving year-round comfort requires a versatile and efficient solution. While traditional systems rely on separate units for heating and cooling, the modern heat pump offers a single, highly efficient system that handles both. Understanding how this ingenious technology works can show you why it's a smart choice for maintaining perfect indoor temperatures, regardless of the season.

At Nugent Mechanical Contractors, we specialize in installing and servicing heat pumps, helping our customers maximize comfort while minimizing energy bills.

How a Heat Pump Works: The Magic of Moving Heat

The simplest way to understand a heat pump is that it doesn't create heat; it moves heat.

• Summer (Cooling Mode): The heat pump functions exactly like a standard central air conditioner. It extracts heat from the indoor air and releases it outside, using refrigerant to cool your home.
• Winter (Heating Mode): This is where the magic happens. Even when the outside temperature is low, the outdoor air still contains heat energy. The heat pump extracts this low-temperature heat from the outside air, compresses it to increase the temperature, and transfers it inside your home.

Because a heat pump simply transfers existing heat rather than burning fuel (like a gas furnace) or using electrical resistance (like electric baseboard heating), it is exceptionally energy-efficient.

Key Benefits of Choosing a Heat Pump

Heat pumps offer several advantages that make them ideal for the climate we experience in West Texas:

• Exceptional Energy Efficiency: Heat pumps are considered one of the most energy-efficient options for both heating and cooling. They can deliver two to three times more heat energy than the electrical energy they consume. This efficiency directly translates to lower utility bills throughout the year.
• Year-Round Comfort from One Unit: You only need one piece of primary equipment to manage all your temperature control needs. This simplifies maintenance, as you only have one system to tune up annually.
• Improved Dehumidification: Heat pumps are excellent at removing moisture from the air during the cooling cycle, leading to improved air quality and a more comfortable environment in the summer months.
• Safety: Unlike gas furnaces, heat pumps do not burn fuel, eliminating the risks associated with gas leaks or carbon monoxide exposure.

The Role of Supplemental Heat

While modern heat pumps are incredibly efficient, their ability to extract heat from the outside air decreases when temperatures drop well below freezing. In the Lubbock area, we sometimes experience deep cold snaps.

In these conditions, the heat pump relies on a secondary, backup heat source, often called auxiliary heat or strip heat (electric heating coils). This supplemental heat ensures your home stays warm no matter the outdoor temperature. While this electric heat is less efficient than the pump itself, it only engages when truly necessary, ensuring continuous comfort and safety.

If you're considering a highly efficient, all-in-one comfort solution for your home, the heat pump is a superior choice. Contact Nugent Mechanical Contractors today. We'll help you select and install the perfectly sized heat pump system to keep your home comfortable and your energy bills low.

Your Annual Must-Do: Why Your Heating System Needs a Professional Tune-Up Every Year

In Lubbock, we rely on our heating systems to battle those sudden, sharp winter chills. But just like your car, your furnace is a complex machine that experiences wear and tear. If you wait for a breakdown before calling for service, you're not only risking a freezing night but also inviting costly repairs.

At Nugent Mechanical, we can't stress this enough: your heating system needs a professional tune-up every single year. This isn't just a recommendation—it's the single most effective way to ensure safety, reliability, and efficiency all season long.

1. Guaranteeing Your Family's Safety

This is the most critical reason for an annual inspection. Furnaces—especially gas models—create heat through combustion. When components wear out, they can create dangerous situations:

• Carbon Monoxide (CO) Leaks: A professional tune-up includes inspecting the heat exchanger for small cracks. A cracked heat exchanger can leak odorless, colorless, and poisonous carbon monoxide into your home. Technicians use specialized tools to check for this silent killer.
• Fire Hazards: Loose wiring, dirty burners, and debris near the ignition system can all pose a fire risk. We check and secure all electrical connections to prevent hazards.
• Gas Leaks: We inspect all gas lines and connections to ensure there are no leaks that could pose an explosion risk.

2. Protecting Your Warranty (A Financial Lifeline)

Almost every major furnace manufacturer's warranty requires proof of annual professional maintenance to remain valid. If your system breaks down and you haven't had a recent tune-up, the manufacturer can void your warranty, leaving you responsible for the entire cost of replacing expensive parts like the heat exchanger or compressor.

A yearly maintenance receipt from Nugent Mechanical is your documented proof that you’ve done your part to protect your investment.

3. Maximizing Energy Efficiency and Saving Money

A dirty, unmaintained furnace has to work harder and run longer to heat your home, which directly translates to higher utility bills.

• Efficiency Restoration: A professional cleaning removes grime and dirt from the burners, blower, and critical components. This simple step restores lost efficiency, often saving homeowners enough money on their utility bills to cover the cost of the tune-up itself.
• Peak Performance: When all components are clean and calibrated, your system runs at peak performance, ensuring warm, consistent air without wasting fuel.

4. Avoiding Costly Mid-Winter Breakdowns

A typical tune-up allows a trained technician to spot minor issues—like a worn blower belt, a failing ignitor, or a low-amperage draw on a motor—before they cause a complete system failure.

• Proactive Repairs: By fixing a $50 component now, you avoid an emergency $500 repair call on Christmas Eve.
• Convenient Scheduling: Scheduling maintenance in the fall allows you to pick a time that works for you, rather than waiting in line for an emergency technician during a regional cold snap.

Schedule Your Tune-Up with Nugent Mechanical

Don't gamble with your family's comfort or safety. An annual pre-season maintenance check is the smartest investment you can make in your home's well-being. Contact Nugent Mechanical today to schedule your professional furnace tune-up and start your winter season with confidence and peace of mind.

Common Furnace Problems and How to Fix Them

When the temperatures drop Lubbock, a reliable furnace isn't just nice to have—it's essential. Most furnace troubles announce themselves with clear symptoms, and knowing how to troubleshoot them can save you time, money, and discomfort.

While some issues require calling a professional, many common problems have simple, DIY solutions. At Nugent Mechanical, we want you to be prepared! Here are the most frequent furnace issues and what you can do to address them.

Problem 1: The Furnace Isn't Producing Heat (or Won't Turn On)

This is the most common and immediate crisis, especially during a cold snap.

Problem 2: The Furnace is Blowing Cold Air

Your blower is running, but the air coming out of the vents isn't warm.

• Pilot Light/Ignitor Failure (Gas Furnaces): If the pilot light is out (or the electronic ignitor fails), the furnace can't burn gas to create heat. You can try to safely relight the pilot light following the instructions on your furnace, but if it won't stay lit, the thermocouple may be faulty.
• Dirty Flame Sensor: This safety device ensures the gas valve is closed if the burner flame goes out. If it's covered in soot, it mistakenly senses no flame and shuts off the gas, resulting in cold air. A technician can safely clean or replace this sensor.
• Overheated Unit: The heat exchanger may be so dirty (or the filter so clogged) that the furnace is immediately hitting its safety limit and shutting off the burner.

When to Call: If the pilot light won't stay lit, or if the unit is repeatedly cycling on and off.

Problem 3: Strange Noises Coming from the Furnace

Your furnace should run quietly. Any new or loud sounds indicate a component is failing or broken.

When to Call: If the noise is loud, persistent, or accompanied by a loss of heat. Worn belts and bearings put extreme stress on the motor and need immediate repair.

Problem 4: High Energy Bills

The furnace seems to be running fine, but your utility bill is unusually high.

• Lack of Maintenance: This is the biggest culprit. An unmaintained furnace can lose up to 5% of its efficiency each year it goes without a professional tune-up.
• Old Filter: A dirty filter forces the motor to run longer, wasting energy.
• Poor Insulation/Drafts: Your home itself may be losing heat through drafts or poor attic insulation, forcing the furnace to run constantly.

Your DIY Fix: Enroll in a preventive maintenance plan and consistently replace your air filter every 30–90 days. Check windows and doors for drafts.

When to Trust the Professionals

While DIY fixes are great for simple issues like filters and switches, leave anything involving gas lines, electrical components, or internal repairs to the certified technicians at Nugent Mechanical. We use specialized diagnostic tools to locate the problem quickly and safely, ensuring a lasting repair.

Don't ignore the warning signs! Contact us today for reliable service that keeps your furnace running efficiently and safely all winter long.

Carbon Monoxide: Understanding the Silent Danger from Your Furnace

Carbon monoxide (CO) is often called the "silent killer" because it is an odorless, colorless, and tasteless gas that is nearly impossible to detect without specialized equipment. In the winter, one of the most common sources of CO leaks in homes is a malfunctioning or poorly maintained furnace. Since your health and safety are our top priority, Nugent Mechanical Contractors wants to ensure homeowners in Lubbock understand the warning signs and how to protect themselves.

Why Your Furnace Can Leak CO

Natural gas, propane, and oil furnaces burn fuel to create heat. When the fuel burns cleanly, the byproducts (including CO) are safely vented outside through the flue. A leak occurs when:

• A Cracked Heat Exchanger: This is the most common cause. Over time, heat and stress can cause cracks in the heat exchanger, allowing CO to mix with your conditioned air and be distributed throughout your home.
• A Blocked Flue or Chimney: Debris, leaves, or even bird nests can block the vent pipe, preventing harmful exhaust gases from escaping outside. This forces CO back into your living space.
• Improper Ventilation: If the furnace itself is starved for fresh air, it can lead to incomplete combustion, which produces much higher and more dangerous levels of CO.

   

Physical Warning Signs: Symptoms of CO Poisoning

The symptoms of CO poisoning are often mistaken for the flu or a bad headache, which makes the gas so dangerous. If you or members of your family experience any of the following, especially when you are inside your home and the symptoms improve when you leave, a CO leak is a serious possibility:

If you suspect CO poisoning, get everyone, including pets, out of the house immediately and call 911.

Equipment Warning Signs: Your Furnace is Telling You Something

Beyond physical symptoms, your furnace and surrounding equipment often display noticeable warning signs that signal a problem with combustion or venting:

• Yellow or Orange Pilot Light: The pilot light or burner flame should be a crisp blue color. A yellow, orange, or unsteady flame indicates incomplete combustion, which produces more CO.
• Excess Moisture/Condensation: Excessive condensation on cold surfaces like windows or cold exterior walls near the furnace can be a sign that exhaust gases are not venting properly.
• Soot or Stains: Streaks of soot, rust, or black/brown stains around the furnace, vent pipe, or appliance openings are major indicators of a serious venting issue.
• Unusual Odors: While CO itself is odorless, the exhaust fumes from a failing furnace may smell "stale" or "stuffy."

The Most Important Safety Device: The CO Detector

The only reliable way to detect carbon monoxide is with a Carbon Monoxide Detector.

• Install detectors on every level of your home, especially near sleeping areas.
• Check and replace the batteries (or the unit itself, typically every 5–7 years) according to the manufacturer's recommendations.
• If the alarm sounds, evacuate the house immediately and call 911 and then Nugent Mechanical.

Preventative Care is the Best Defense

The best way to prevent a CO leak is through annual professional maintenance. During a tune-up, a Nugent Mechanical technician will perform crucial safety checks, including inspecting the heat exchanger and ensuring all venting is clear and properly sealed. Don't gamble with your family's safety. Contact Nugent Mechanical today to schedule your safety inspection and ensure your furnace is running cleanly and safely all season long.
