How to Prepare Your Air Conditioner for the Summer

As summer approaches, the last thing you want is for your central air conditioner to fail during those first sweltering days. Preparing your air conditioning system for summer is essential to ensure your home stays cool and comfortable as temperatures rise.

At Air Specialities, we understand that the best summer days are those when you can slip into a relaxing air-conditioned home after enjoying some fun in the sun. Since 1952, we’ve been keeping it cool for both residential and commercial HVAC customers throughout West Haven, CT, and the surrounding service area. Our decades of experience mean we know the ins and outs of every AC system, from the oldest models that have been part of homes for generations to the sleek new units dotting commercial landscapes. 

Let’s dive into how you can get your AC unit ready for the heat so you can chill out all season long. 

Breeze Through the AC Basics

An air conditioner is a system designed to cool your home or office, making those hot days more comfortable. At the heart of this system are the outdoor compressor and condenser units, which are crucial for the air cooling process. The compressor pumps a substance called coolant through the coolant lines, moving it between the indoor and outdoor units. 

As the coolant flows into the indoor evaporator coils, it absorbs heat from the indoor air, effectively lowering the temperature. The air handler then pushes the cool air through the air filter, which cleans it by removing particles and allergens. This filtered, cool air then circulates throughout your space. 

Meanwhile, the absorbed heat is transferred back outside through the condenser coils and released outdoors. This cycle repeats to keep your space at a comfortable temperature.

Step-by-Step Guide to Preparing Your Air Conditioner

1. Start with a Safety Check

Always begin by turning off the power to your HVAC system at the circuit breaker. This protects you as you perform maintenance checks and clean various components.

2. Replace or Clean the Air Filter 

One of the simplest yet most effective ways to boost your air conditioner’s performance is to clean or replace the air filter. A clogged or dirty filter restricts airflow, forcing your system to work harder. Where does that leave you? With increased energy bills and possibly a premature replacement. Check your filter monthly and swap it out or clean it as needed.

3. Clean the Outdoor Unit 

Over time, your outdoor unit might collect debris, such as leaves, dirt, and grass clippings, which can impede airflow. Gently clean the fan blades and condenser coils with a garden hose, and make sure the area around the unit is clear of vegetation and clutter for at least two feet.

4. Check for Proper Airflow 

Make sure that the vents throughout your home are open and unobstructed. This includes checking that furniture, rugs, or drapes are not blocking air supply vents, as restricted airflow can cause the system to work inefficiently.

5. Test the System 

After you’ve completed the maintenance checks and cleaning, turn the power back on. Test the system by setting the thermostat to cool and lowering the temperature to see how the AC responds. Listen for unusual noises and monitor for any distinctive smells. It might be time to call in a professional if anything seems out of the ordinary.

When Your Air Conditioner Unit Demands Professional Attention

While regular maintenance can be handled on your own to a certain extent, some signs indicate the need for a professional touch. 

  • The air conditioning unit is making unusual noises, such as grinding or squealing.
  • You notice an unexpected increase in your energy bills.
  • There is weak airflow from the vents.
  • Warm air is blowing out of your AC unit.
  • Moisture or leakage around the system, particularly around the indoor unit, points to refrigerant leaks or a blocked drain tube. 

These are signs of underlying issues that need to be fixed as soon as possible if you want to be cool through the summer. Contacting an HVAC technician from Air Specialties is crucial for these complex issues!

Why Do I Smell Gas When My Furnace Kicks On?

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.

6 Best Spring Cleaning Tips for AC Maintenance

Spring cleaning and air conditioner maintenance are essential to ensuring the system runs efficiently and avoids breaking down when you need it most. Of course, it’s a good idea to clean your vents and remove debris collected in or around your outdoor unit. But several components of your AC system aren’t as easy to get to that also need to be considered when cleaning your air conditioner in the spring. 

Air Specialties provides AC tune-ups in New Haven County. With our years of experience in serving HVAC units, we’ve come up with these spring cleaning AC tips highlighting some important areas of your cooling system that require a professional to clean.

1) Evaporator & Condenser Coils 

The first step in ensuring you have a clean air conditioner in the spring is checking the coils. Dirty condenser and evaporator coils can reduce the efficiency of an air conditioner and make it work harder, leading to increased energy consumption and cooling costs. If your air conditioning unit’s coils have collected dust and debris that can interfere with their operation, one of the most vital spring cleaning AC tips is to have a technician clean them during a service appointment. Coils can be delicate components in your AC unit, so only a professional should remove and clean them. 

2) Fan Blades

A qualified technician can check the AC unit’s blower fan blades to ensure they are clean and in working order. Dirty blower fan blades can make the blades imbalanced and reduce the airflow in your air conditioner. As a result, the decreased airflow can cause your condenser coils to freeze, leading to ice buildup and damage to the system. 

3) Drainage System

Bacteria can build up in the drainage system of your AC unit, causing mold and mildew to form. When this happens, you will notice musty smells coming from your vents. Debris can also college in the line preventing it from draining properly. During a routine cleaning, an HVAC technician can inspect your drainage lines to ensure they are free of any obstructions and don’t have any signs of mold, mildew, or algae. 

4) Ductwork

Dust, pollen, and other debris can collect in AC ductwork, particularly in areas with high pollution or homes with pets. Sometimes, odors may indicate problems with ducts requiring cleaning. But, in other instances, there are no signs of a reduction in air quality caused by dirty ducts that can trigger allergies and other illnesses. Generally, air ducts should be cleaned by a professional once every three to five years.

In addition to these spring cleaning AC tips, several other steps should be included in a maintenance checkup of your AC system to ensure it’s running correctly. Those steps include the following:

5) Checking Refrigerant Levels

The refrigerant in your AC unit absorbs heat from the air that cools your home. Therefore, if the refrigerant level is low, that will impact your unit’s ability to function. 

6) Replacing the Air Filter

Dirty air filters can also reduce the efficiency of your air conditioner. They are essential in ensuring you have a clean air conditioner in the spring and help ensure your air conditioner is working up to its capacity. An air filter clogged with dust and debris can restrict the airflow into your HVAC system and cause it to work harder. Additionally, dirty air filters can allow allergens to enter your home and reduce indoor air quality.

Furnaces Heating

Why Is My Furnace Running Constantly?

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.

Is Your Furnace Short Cycling? Here’s What to Do

There’s nothing like a cozy and comfortable home during the cold winter months. But keeping your home warm when the temperatures drop below freezing takes a toll on your furnace. It can even cause the system to become inefficient and develop mechanical issues if proper care and maintenance are not taken into account. 

A typical problem with your furnace is short cycling or overheating. Short cycling refers to the start-and-stop cycle that keeps the furnace from properly heating your home. 

So what causes short-cycling furnaces? Can it be remedied? Here are some things you should know about short-cycling heating systems.


It’s a complex question: “Why is my furnace short-cycling?” However, some common problems result in short cycling, such as an overheating system. If your furnace starts to overheat, it may shut off to prevent further damage. 

Overheating can also potentially create cracks in your heat exchanger, which could lead to dangerous carbon monoxide leaks in your home.

What to Do: Contact your local heating specialists to have them repair your unit according to its specific needs. When your furnace is working properly, you shouldn’t have to worry about overheating.

Thermostat Problem

If you have a short-cycling heater, turn next to your thermostat.

A broken or poorly placed thermostat is one of the leading causes of short cycling in furnaces. You may also want to rethink the location of your thermostat. Ideally, a thermostat that is placed too close to a heat source or in direct sunlight tends to warm up too quickly. This signals your furnace to shut off before your home is adequately warmed.

What to Do: Don’t place your thermostat directly over a heat register or near a drafty door or window. Test the unit regularly to ensure it is working optimally. Is your thermostat mounted in the wrong place? You can choose to either relocate the thermostat yourself or reach out to a professional for assistance.

Age-Related Problems

Maybe unsurprisingly, a short-cycling furnace can be linked to old age.

Your furnace’s efficiency tends to decline with age. An old and faulty furnace will short cycle more often and fail to warm your space adequately. Like all the other devices in your home, a furnace is subject to regular wear and tear, which becomes more pronounced with age.

What To Do: Wait until the furnace exhausts its usefulness due to advanced age before you act. Even if your old furnace has no significant mechanical issues, update it with a newer version that provides better performance and is more energy-efficient.

Dirty Air Filter

Dirty air filters restrict airflow and cause pressure to build up inside your system. The blocked air in the furnace, in turn, raises internal temperatures causing the unit to shut off automatically.

What to Do: Replace your air filters regularly, at least once each month, to prevent blockages and restricted airflow that leads to short cycling. You should also schedule frequent cleaning and maintenance to avoid clogged air filters.

Oversized Furnace

Have you checked the potential causes above but still find yourself asking, “Why is my furnace short-cycling?” If your furnace is short cycling with a new filter, an oversized furnace may be to blame. A heating system that’s too big for your home is one of the most common causes of short-cycling furnaces.

An oversized furnace that doesn’t match your home’s size may heat your small spaces quickly but unevenly. Such furnaces will short cycle rapidly with the rising temperatures in your home. Also, households with poor insulation may experience rapid short cycling. In this scenario, the furnace could be producing adequate heat, which is then lost through faulty seals, holes, and cracks.

What to Do: Install an appropriately sized furnace for the size of your home to avoid a short-cycling heater. You should also insulate your areas adequately to prevent energy loss.

Bad Flame Sensor

If you have a short-cycling furnace, you may be dealing with a malfunctioning or dirty flame sensor. When you have a bad flame sensor, your furnace flame will shut off right after lighting. If your furnace turns off after two to 30 seconds, this may be because your malfunctioning flame sensor cannot detect the heat created by the furnace. As a result, the gas valve closes and shuts off your furnace.

Although a malfunctioning flame sensor may shut off the gas at the wrong time, you shouldn’t feel too frustrated about this problem occurring. Flame sensors are safety devices that are simply trying to ensure that gas doesn’t enter your home and put your health at risk. If you’re experiencing this issue, rest assured that it’s nothing a professional HVAC technician can’t fix.

What to Do: You’ll need to either clean or replace your flame sensor with the help of a professional technician. A replacement will be needed if the sensor is broken or cracked.

Malfunctioning Blower Motor

While less common, a problem with the blower motor can cause a short-cycling furnace. The blower motor works by pushing air through your heating system and sending it out into your home. However, when the blower motor malfunctions, the warm air that’s generated will collect inside your furnace with no way of escaping — causing the furnace to turn off for safety reasons.

When it comes to a furnace blower motor, it’s important that the hot air flows out into your home. If the heat gets trapped inside the furnace, this can lead to overheating and cause damage to various critical parts. Although this problem can get in the way of your family’s comfort, it’s also important to recognize that a blower motor issue can lead to further repairs or a replacement if not handled promptly.

What to Do: Inspect your vents for proper airflow. If you notice a weak airflow — or none at all — this could mean that your blower motor is faulty. When you contact a professional HVAC technician for assistance, they’ll let you know if the blower motor needs to be replaced or if it can be repaired. Our heating experts specialize in everything from furnace replacements to boiler repair in CT, so you can trust us to provide you with a reliable solution.

Blocked Exhaust Flue

Have you checked all the possibilities above but still find yourself asking, “Why is my furnace short-cycling?” There’s one more crucial option worth considering: the exhaust flue is blocked.

Your furnace’s exhaust flue is responsible for venting the noxious gases that are created during the combustion process. This small but mighty component is incredibly important, as it helps prevent these gases from entering your home.

However, it’s important to know that this part isn’t immune to problems. There’s a chance that the flue can become clogged with debris, foreign objects, or an animal’s nest. If the flue detects a blockage, the component will tell the furnace to shut down completely.

What to Do: You can shut off the furnace and disconnect the flue to inspect it for a clog. From here, you might be able to extract the blockage yourself. If you suspect that an animal is in the flue or you don’t feel comfortable handling the job yourself, you should contact a professional for assistance.

Air Conditioner

6 Reasons Why Your Air Conditioner Turns Off By Itself

Air conditioning problems can be incredibly frustrating, especially if temperatures are reaching record highs just outside your door. One common problem that can cause many homeowners to scratch their heads is when their AC unit turns off after about 15 minutes. One minute your air conditioner could be running fine, and the next, the unit has completely shut off. While this problem can be downright puzzling, it can also put your comfort at risk since your home never gets as cool as you would like it to.

So, why does your air conditioner turn off by itself? There can be several different reasons why this issue is happening. Let’s go over them in more detail below.

Faulty Thermostat

If your air conditioner keeps shutting off, you’ll want to first check the thermostat. Your thermostat may fail to properly sense the temperature inside your home. While this problem can be due to an electrical issue, you might want to replace your thermostat’s batteries to see if this simple fix makes a difference.

Try replacing the batteries, and if the problem persists, don’t hesitate to contact a professional for help. A technician will perform a repair, or they might suggest relocating the thermostat to a different part of the house. If your thermostat is currently in a shady place or near a cool air vent, the device might inaccurately believe that your entire home is cool and could shut off the AC unit as a result.

Dirty Air Filter

Why does your air conditioner turn off by itself? The issue could lie with the air filter. Believe it or not, keeping the filter in your HVAC system clean can make a significant difference when it comes to your comfort, electric bills, and air conditioner performance.

Short cycling is a common problem associated with dirty air filters. When the air filter becomes blocked with debris, this makes it difficult for air to pass to and from the air conditioner’s air handler. This poor airflow can cause the evaporator coils to freeze — and the AC unit can shut off as a result. Additional signs of frozen evaporator coils can include water leaks and a clogged condensate drain line.

Refrigerant Leaks

If your air conditioner keeps shutting off, you’ll also want to be on the lookout for any refrigerant leaks. As your air conditioner gets older, it can experience different types of wear and tear. Corrosion and weakening components could lead to these leaks.

Low refrigerant levels can cause many problems for air conditioning systems. For example, this problem often creates a sudden change in pressure that causes the outdoor compressor unit to shut down.

Damaged Compressor

Your air conditioner has two important components: the indoor unit and the outdoor unit. As we mentioned above, this outdoor system is known as a “compressor.” Like most other parts, this compressor can experience wear and tear over time — and that might be why your AC unit keeps shutting off.

So, why does your air conditioner turn off by itself when it has a damaged compressor? When it comes down to it, your air conditioner can’t do its job without a fully-functioning compressor. If this unit overheats, malfunctions, or fails completely, the entire cooling system will shut down as a result.

The problem could be caused by dirt and debris getting inside the unit, or it could potentially be due to regular old age. No matter the reason, it’s important to contact a professional technician to get to the bottom of the problem once and for all.

Malfunctioning Run Capacitor

If your air conditioner keeps shutting off after checking for the problems listed above, you could be dealing with a faulty run capacitor. What is a run capacitor? Think of it as the device that gives air conditioning units a sudden rush of energy when starting a new cooling cycle. The run capacitor is constantly storing energy, which it will provide to ensure that the air conditioner’s fan motor is running properly.

When you have a malfunctioning run capacitor on your hands, the air conditioner won’t receive the continuous supply of energy it needs to keep on running. In the end, this could be why your air conditioner starts then stops after only a few seconds.

Oversized AC

When your air conditioner keeps shutting off, you should check to make sure that your cooling system isn’t too large for your house. Although you might think installing an oversized air conditioner will benefit you and your family in the long run, it won’t actually improve your comfort. Instead, you might experience the exact opposite.

If your AC is too big, it’ll finish cooling your home much quicker than if you’d installed a smaller unit. While this may seem like a perk, the air conditioner will end up shutting down much quicker as a result. As you can probably imagine, you could end up experiencing hot and cold spots throughout your home, as well as higher energy bills.

How can you fix this problem? It all comes down to contacting a professional for a New Haven AC replacement. It’s important to ensure that you install an air conditioner that fits your home’s size and cooling needs.
