No Comments on Signs Your Heat Exchanger Is Failing (Before It’s Too Late)

If you’re a homeowner who relies on a gas furnace to keep warm, the idea of a failing heat exchanger likely raises concerns. A damaged heat exchanger isn’t something you’d want to ignore, especially when it can lead to significant safety and efficiency issues. Understanding the warning signs of a cracked heat exchanger could save you from costly repairs and even more serious dangers down the road.

As a leading HVAC company in New Haven County, Air Specialties is here to break down all you need to know when it comes to your furnace’s heat exchanger, including signs it’s in trouble. When you notice any of these irregularities, call us right away for prompt furnace repair. We’ll implement long-lasting solutions or recommend a furnace replacement if your current system is outdated and unable to keep up with your comfort needs.

What Is a Heat Exchanger, and Why Is It Essential?

In any furnace, especially gas furnaces, the heat exchanger plays a crucial role in warming up the air that circulates through your home. It’s essentially the chamber where combustion occurs, and the generated heat is transferred to the air, which is then blown into your living spaces. A properly functioning furnace heat exchanger keeps combustion gasses, like carbon monoxide, separate from the indoor air you breathe.

The heat exchanger comes in two main parts: the primary heat exchanger, which handles the bulk of the heating, and the secondary heat exchanger, which recovers additional heat to increase energy efficiency. Over time, these components can develop cracks due to regular wear and tear, which can lead to a host of problems, some of which can be deadly.

Why a Failing Heat Exchanger Is Dangerous

A cracked heat exchanger can release harmful gasses into your home, including carbon monoxide — a colorless, odorless gas that’s potentially lethal in high concentrations. When the integrity of the furnace’s heat exchanger is compromised, you face the risk of carbon monoxide poisoning, a danger that should never be underestimated.

Beyond the health hazards, a faulty heat exchanger can also lead to higher utility bills. Cracks in the exchanger can disrupt the heating system’s ability to function efficiently, requiring more energy to maintain a comfortable temperature. These cracks can also strain other components, accelerating their wear and potentially shortening your furnace’s lifespan.

Common Signs of a Failing Heat Exchanger

Identifying early signs of a failing heat exchanger can help prevent dangerous situations. Here’s what to watch for:

Odd Smells in Your Home

A cracked heat exchanger may cause unusual odors. If you notice a sulfuric or metallic smell coming from your heating system, it could be an early indicator of cracks. These odors come from combustion gasses that leak from the damaged exchanger and may signal an underlying problem. Taking note of this smell and having it inspected can make all the difference in your heating system’s longevity.

Yellow or Flickering Burner Flame

A gas furnace typically has a stable, blue flame when it’s running properly. If you notice that the burner flame has turned yellow or started flickering, it’s often due to improper combustion, which could indicate a faulty heat exchanger. A cracked exchanger disrupts airflow within the furnace, causing incomplete combustion and a shift in flame color. A professional inspection can quickly identify whether this flame behavior is related to heat exchanger cracks or another issue.

Soot Buildup Around the Furnace

Another warning sign to look out for is soot buildup around your furnace. When the furnace’s heat exchanger fails to perform properly, it can result in excessive soot or a dark, dusty residue near the furnace. This buildup indicates that the combustion process isn’t occurring as it should, which can be caused by heat exchanger damage. Not only does this soot signify a potential issue with the furnace, but it can also reduce air quality in your home and increase the risk of respiratory problems.

Visible Cracks or Corrosion

If you can access and visually inspect your furnace, check for any obvious cracks or signs of corrosion on the heat exchanger. Rust and corrosion weaken the metal and increase the likelihood of cracks developing. This deterioration happens naturally over time, especially in older heating systems, but it’s essential to address visible damage sooner rather than later.

Unexplained Health Symptoms Among Family Members

If anyone in your household experiences sudden flu-like symptoms, including headaches, dizziness, nausea, or fatigue, it could be due to a carbon monoxide leak from a faulty heat exchanger. Carbon monoxide poisoning has symptoms similar to those of common illnesses, making it harder to identify without a carbon monoxide detector. When these symptoms appear in combination with any of the furnace issues mentioned, there’s a strong chance that your heating system could be to blame.

Steps to Take if You Notice These Signs

When you suspect a problem with your furnace’s heat exchanger, prioritize the safety of your household. If there’s a carbon monoxide leak, open windows immediately to ventilate your home. Turn off the heating system and avoid using it until a professional can perform a thorough inspection. Investing in a carbon monoxide detector is also an important safety step, as it can alert you to dangerous levels of gas in your home.

Scheduling an inspection with HVAC professionals as soon as possible will ensure that any heat exchanger cracks are identified and repaired. They can assess the severity of the problem and recommend the appropriate course of action, whether that’s repairing or replacing the damaged component.

Preventative Measures to Avoid Heat Exchanger Failure

Routine maintenance can help prevent heat exchanger issues before they start. Scheduling annual inspections allows HVAC technicians to detect and resolve small problems early, reducing the risk of larger failures. During these checkups, technicians clean and assess your furnace to check that every part functions optimally.

Regular filter changes also go a long way toward protecting your furnace’s heat exchanger. When filters become clogged, it can cause the furnace to overheat, leading to strain on the heat exchanger. By replacing filters according to the manufacturer’s recommendations, you can extend the lifespan of your furnace and avoid costly repairs.

When Heat Exchangers Should Be Replaced

Repairing a cracked heat exchanger is possible in some cases, but if the furnace is old or if the damage is extensive, replacement might be the better option. Repair costs can add up quickly, especially when combined with the risk of further issues down the line. In contrast, a new furnace, while more of an investment, provides peace of mind and a warranty that covers potential future repairs.

If you’re dealing with frequent breakdowns, rising energy costs, or excessive repairs, it may be time to replace your furnace. An HVAC technician can evaluate your furnace’s overall condition and advise on whether a repair or replacement makes the most sense for your situation.

No Comments on How to Prep Your Furnace for the Fall and Winter: Tips for a Cozy Season

The crisp autumn air signals the approaching winter season, reminding us it’s time to prepare our homes for the cooler months ahead. One of the most important ways you can do that is by making sure your furnace is up for the task of keeping you cozy. After all, nobody wants to be stuck shivering when a heating system breakdown hits unexpectedly.

Air Specialties is here to lay out the simple steps you can take to get your furnace in shape. We’ve been a staple in the West Haven, CT region for over 70 years, so we know a thing or two about HVAC systems and what they need to continue working without a hitch. Give us a call to book any of our heating services, including furnace repair, furnace maintenance, and furnace installation.

Replace the Air Filter

Your furnace’s air filter plays a crucial role in maintaining indoor air quality and system efficiency. Dirty filters restrict air flow, forcing your furnace to work harder and potentially increasing energy consumption. Regular replacement of air filters helps your HVAC system operate smoothly while improving the air you breathe.

Pro tip: Mark your calendar for monthly air filter checks and replacements every 30-90 days, depending on the type of filter and your household needs. Homes with pets, for example, may need more frequent replacements due to additional dander and fur. Winter has a heavy workload on your furnace, so be proactive by keeping the air filters fresh and clean.

Check the Thermostat Settings

Autumn presents the ideal opportunity to reassess your thermostat settings. Double-check that it’s set to “heat,” not “cool.” Also, consider upgrading to a programmable thermostat if you haven’t already. These smart devices allow you to set different temperatures for various times of the day, optimizing comfort and energy usage.

Clean Furnace and Vents

A clean furnace is a happy furnace. Dust and debris can accumulate around your furnace over time, potentially causing performance issues or safety concerns. Take a moment to clear the area around the furnace, removing any items that might obstruct airflow. Not only will this help maintain good indoor air quality, but it also reduces the chance of overheating or other malfunctions.

Don’t forget about the vents, either. Dusty or blocked vents can hinder warm air distribution, forcing your heating system to work harder and reducing energy efficiency. Vacuum the vents to remove dust and debris, allowing for smoother and more efficient operation throughout your home.

Inspect the Furnace for Signs of Wear

A quick visual inspection of your furnace can reveal any signs of wear or damage that might impact performance. Start by examining the exterior of the furnace for any visible issues like rust, corrosion, or loose panels. If you notice unusual wear, it may indicate that components like the heat exchanger or blower motor need attention.

For deeper insight, remove the access panel to check for soot buildup, which could suggest incomplete combustion. Incomplete combustion not only affects efficiency but also risks releasing carbon monoxide — a dangerous, odorless gas. If you’re uncomfortable performing these inspections yourself, a professional can assist in identifying potential problems before they escalate.

Test the Furnace Early

Don’t wait for the first cold snap to discover your heating system isn’t functioning properly. Test your furnace on a mild day well before you’ll need it regularly. This early trial run allows you to identify and address any issues without the pressure of freezing temperatures.

Listen for any strange noises, check for even heating throughout your home, and pay attention to how quickly your space warms up. Any irregularities warrant further investigation.

Check Carbon Monoxide Detectors

Carbon monoxide, an odorless and colorless gas, poses a serious threat to your family’s safety. Properly functioning carbon monoxide detectors are your first line of defense against this silent danger. Test all carbon monoxide detectors in your home and replace batteries as needed.

If your home lacks carbon monoxide detectors, installing them near bedrooms and on every level of your house is crucial. This small investment can provide immeasurable peace of mind during the heating season.

Schedule a Professional Tune-Up

While DIY maintenance is valuable, nothing replaces the expertise of a professional HVAC technician. Scheduling an annual tune-up for your furnace or heat pump can uncover potential issues, make your home more energy efficient, and extend the lifespan of your heating equipment.

During a professional tune-up, technicians typically:

Clean and adjust the burners
Inspect the heat exchanger
Lubricate moving parts
Check electrical connections
Check the thermostat
Assess overall system performance

This comprehensive check-up not only prepares your system for the winter ahead but also helps prevent unexpected breakdowns when you need heat the most.

No Comments on HVAC Horror Stories: The Worst Mistakes Homeowners Can Make

As a family-owned HVAC company serving New Haven, CT, we’ve seen our fair share of heating and cooling mishaps. From disastrous DIY repairs to costly system failures, the worst-case scenarios often stem from common mistakes made by homeowners. These errors can lead to uncomfortable living conditions, skyrocketing energy bills, and even complete system failures.

Don’t let these horror stories become your reality — check out this guide on what not to do when it comes to your home’s HVAC. We also offer a spectrum of residential heating services and air conditioning services. Reach out to learn more or to book an appointment!

Ignoring Regular Maintenance

One of the most common mistakes homeowners make is ignoring regular maintenance on their HVAC systems. It might seem like a small oversight, but the consequences can be dire. Regular maintenance is crucial for keeping your heating and air conditioning systems running like a dream. When you skip these essential service calls, you open the door to a range of problems that can disrupt your home’s comfort and lead to expensive repairs.

Neglecting regular maintenance can result in higher energy bills and reduced system capacity. This is because, over time, your HVAC unit will have to work harder to maintain the desired temperature, leading to increased energy consumption. Moreover, without routine check-ups, small issues that could have been easily fixed can escalate into worst-case scenarios. A minor leak or a clogged filter can eventually cause your air handler to fail, leaving you sweltering on a hot summer day.

To avoid these headaches, it’s good to set up a regular maintenance schedule with a professional HVAC company like Air Specialties. By sticking to a routine, you can catch potential problems early and prolong the lifespan of your appliances, all while saving on utility expenses.

Attempting DIY Repairs

Another common horror story involves homeowners attempting DIY repairs on their HVAC systems. While the DIY approach can be tempting for a new homeowner looking to save money, it often leads to more harm than good. HVAC systems are complex and require a deep understanding of how each component interacts with the others. Without the proper knowledge and experience, a seemingly simple fix can turn into a disaster.

DIY repairs can result in further damage to your system, leading to even more costly repairs and premature replacement down the line. For example, an incorrectly installed part or a misdiagnosed issue can cause your HVAC unit to malfunction, resulting in poor performance or even complete system failure. In some cases, these mistakes can create safety hazards, such as electrical fires or gas leaks, putting your entire house at risk.

Instead of taking matters into your own hands, it’s always best to hire a certified HVAC professional for repairs and maintenance. Experts have the training and tools necessary to handle any job with the right due diligence. Relying on professionals gives you assurance that your HVAC system will be repaired correctly the first time — saving you time, money, and stress in the long run.

Overlooking Proper Installation

Proper installation is the foundation of a well-functioning HVAC system. Unfortunately, many homeowners overlook this crucial step, either by choosing the wrong installer or by trying to cut corners. However, when an HVAC unit is not installed correctly, it may struggle to heat or cool your home as well as it should. This can result in uneven temperatures across different floors of your house, leaving some rooms too hot while others remain too cold. Poor installation can also cause your system to work harder than necessary, leading to increased energy costs and premature wear and tear.

To avoid these problems, go with qualified installers who follow the manufacturer guidelines in the letter. A professional installation ensures that your HVAC system is properly sized, configured, and connected.

Failing to Change Filters Regularly

Air filters play a vital role in the efficiency and air quality of your HVAC system. Yet, one of the most overlooked tasks is changing these filters regularly. Failing to do so can lead to a range of issues that affect both your system’s performance and your home’s indoor air quality.

Air filters clogged with dust, dirt, and other debris restrict airflow through the HVAC unit. This forces the system to work harder to push air through the ducts, resulting in decreased output and higher energy bills. Additionally, dirty filters can compromise the air quality in your home, allowing allergens and pollutants to circulate freely. This can lead to health issues, particularly for those with allergies or respiratory conditions.

To maintain a healthy and efficient HVAC system, it’s important to check and replace your filters on a consistent basis. The frequency of filter changes depends on the type of filter you use and the conditions in your home. For most households, checking the filter every month and replacing it every three months is a good rule of thumb.

Incorrect Thermostat Settings

Thermostat settings may seem like a minor detail, but they have a significant impact on the performance and energy consumption of your HVAC system. Many homeowners make the mistake of setting their thermostats incorrectly, either by setting the temperature too high or too low or by failing to utilize programmable features.

Incorrect thermostat settings can lead to increased energy consumption and unnecessary wear on your HVAC unit. For example, failing to program your thermostat can result in your system operating when it’s not needed, wasting energy and money.

To optimize your HVAC system’s performance in the summer, aim for a setting around 75 degrees Fahrenheit when you’re at home, and a few degrees higher when you’re away. In the winter, keep your thermostat around 68 degrees when you’re home and lower it when you’re sleeping or out of the house. Investing in a programmable or smart thermostat can make this task even easier, allowing you to adjust settings automatically based on your schedule.

Neglecting Insulation and Ventilation

Insulation helps to keep the heat in during the winter and out during the summer, reducing the workload on your HVAC system. If your house lacks proper insulation, you may notice that certain rooms are consistently too hot or too cold, regardless of your thermostat settings. Ventilation, on the other hand, ensures that fresh air circulates throughout your home, preventing stale air and moisture buildup.

To support your HVAC system’s efficiency, consider having a professional assessment done by Air Specialties. We can make any necessary adjustments and improvements so your family can breathe easy.

Using the Wrong Size System

An oversized HVAC unit may cool or heat your home too quickly, causing the system to cycle on and off frequently. This short cycling not only reduces the lifespan of your equipment but also leads to uneven temperatures and increased energy costs. On the other hand, a system that is too small will struggle to maintain the desired temperature, resulting in poor performance. To avoid these issues, have a qualified HVAC technician who can do a load calculation to determine the exact size system that will work best for your house.

Why Do I Smell Gas When My Furnace Kicks On?

Post author By airspecial
Post date February 16, 2024

Smelling gas when your furnace kicks on can be a disconcerting experience. As a homeowner, you should know that the smell of gas inside your home should never be ignored as it can indicate a potentially dangerous situation. Keep reading to find out why you might smell gas, what steps you should take, and how to prevent it in the future.

Understanding Natural Gas and Its Odor

Natural gas is the most common type of fuel used for heating homes. It’s colorless, tasteless, and odorless in its natural state. However, gas companies add a chemical called mercaptan to give it a distinct odor. This smell, often likened to rotten eggs, serves as a safety mechanism to alert you to potential gas leaks.

The Heat Exchanger: A Common Culprit

The heat exchanger in your gas furnace plays a crucial role in heating your home. It separates the combustion chamber from the breathable air in your house. However, a cracked heat exchanger can cause furnace gas leaks, leading to the smell of gas when your furnace kicks on.

A furnace inspection by an Air Specialties HVAC technician can help detect a cracked heat exchanger. Regularly scheduled maintenance and furnace services in New Haven, CT are essential in preventing this issue.

Gas Lines and Furnace Exhaust

Gas lines supply natural gas to your furnace, while the furnace exhaust vents the combustion gases out of your home. A leak in either of these systems can result in a gas smell.

Leak detection in gas lines should always be carried out by professionals. If you smell gas near your furnace, it’s best to call an HVAC technician for a thorough inspection. They have the necessary tools and expertise to detect gas leaks and carry out necessary furnace repairs.

Incomplete Burn in the Combustion Chamber

Sometimes, the gas smell could be due to an incomplete burn in the combustion chamber. This usually happens when the furnace short cycles, i.e., when it turns off before reaching the desired temperature. An incomplete burn can cause an insignificant amount of unburnt gas to enter your home, resulting in a gas odor.

In such cases, a tune-up of your furnace can help ensure it’s working properly and prevent the smell of gas when it kicks on.

Carbon Monoxide: The Silent Threat

While a natural gas leak is dangerous due to the risk of fire or explosion, it’s not the only threat. Carbon monoxide, a byproduct of the combustion process in gas furnaces, is a colorless and odorless gas that can be deadly in high concentrations.

Carbon monoxide detectors are a crucial safety feature in any home with a gas furnace. If your carbon monoxide detector goes off, you should leave your home immediately and call your local fire department.

What To Do If You Smell Gas

If you smell gas when your furnace kicks on, it’s essential to take immediate action. And if the smell lingers, it’s best to err on the side of caution. Turn off your furnace and open windows for cross ventilation. Avoid using anything that could create a spark, such as light switches, phones, or garbage disposals. Immediately leave the house and contact your gas company or local fire department.

Preventing Gas Smells: The Importance of Regular Maintenance

Preventing gas smells starts with regular furnace service and routine maintenance. An HVAC technician can conduct a thorough inspection of your furnace, including the heat exchanger, gas line, and venting system. They can detect potential issues before they become significant problems, ensuring your furnace operates safely and efficiently.

Stay Comfortable and Safe With Air Specialties

If you’re experiencing a gas smell when your furnace kicks on, don’t hesitate to contact Air Specialties. Our team of experienced technicians can provide a comprehensive furnace inspection in New Haven, CT — ensuring your heating system is safe and functioning at its best.

Why Is My Furnace Running Constantly?

Post author By airspecial
Post date December 15, 2022
No Comments on Why Is My Furnace Running Constantly?

Mature Woman Using App On Phone To Control Digital Central Heating Thermostat At Home

Why is my furnace running constantly? Many people ask this question while wondering how long a furnace should run before shutting off. What if your furnace keeps running when the thermostat is off?

Gas furnaces that run constantly are annoying to listen to, wear down the system, and increase your monthly energy bill. Luckily, the possible causes are easy to spot and don’t take long to fix.

Here at Air Specialties, we’ve provided a list of reasons to help you answer the question of why the furnace is running constantly. We’re your CT heating specialists, with a team of certified technicians that can diagnose and repair any problem with your HVAC system.

What Is the Typical Furnace Run Time?

How long should a furnace run before shutting off? Typically, you can expect furnace cycles to run two to three times per hour. Each cycle runs for about 10-15 minutes. During freezing weather, this cycle may increase slightly.

Reasons My Furnace Is Running Constantly

Why is my furnace running constantly? There are several reasons why this may be happening. Here are some steps to follow to troubleshoot the cause of the issue:

1. Dirty Furnace Air Filter

A dirty furnace filter is the most common reason why your furnace may constantly be running. Your HVAC system must pull air into the equipment to warm the air before it circulates back out through the vents.

A dirty air filter can obstruct your furnace, causing it to work harder to meet your heating demands. However, it will continue to run until your home reaches the desired temperature.

If your air filter is dirty, replace it with a new one. You should do this every 1-3 months.

2. Wrong Thermostat Setting

Why is my furnace running constantly? If your thermostat is set too high, it will keep running to get it to that temperature. You may notice your house is hot before becoming aware that the furnace keeps running. Check your thermostat to see the set temperature.

It’s also possible that you have a malfunctioning thermostat. For example, if your thermostat runs after the temperature change, it may be faulty.

3. Blower Issues

When your furnace is turned on but not producing warm air, the cause is likely an issue with the blower. For example, the blower may have corroded wires, or the fuse may have blown.

If your room temperature feels colder than usual, check your thermostat. Since this problem involves electrical components, contact a professional HVAC company to fix the issue.

4. Faulty Limit Switch

The limit switch controls the heat in your furnace. When the thermostat sends a signal to the controller that it’s time to turn on the heat, the switch sends a signal to the furnace.

If your furnace has a faulty limit switch, it may not receive the signal. This lapse can cause it to run more often than necessary. A faulty limit switch may also be why your furnace keeps running when the thermostat is off. You should call an HVAC technician to perform an inspection if you suspect this is the issue.

5. Malfunctioning Pilot Light

A pilot light ignites the gas before it reaches the burner. If it’s malfunctioning, the broken pilot light can cause your furnace to run constantly. The reason is that the system can’t reach the set temperature without a sufficient supply of gas to warm the air.

If the pilot light is malfunctioning, you may need to call an HVAC professional to have it replaced. In addition, you can find the reset button on your furnace to try resetting the pilot light, which may solve the problem. If this doesn’t work, it may be an issue with the heat exchanger.

Schedule an Inspection or Repair With Our Service Experts

Why is my furnace running constantly? How long should a furnace run before shutting off? Does your furnace keep running when the thermostat is off? Air Specialties can inspect your furnace and repair any heating system problems.
