Common Problems with Older HVAC Units   Air Conditioner Repair in Cleveland TN TN

Air conditioning units have a limited shelf life, especially in Cleveland, TN. This is due to exposure to natural elements like humidity, heat, and storms. Several factors play a role in how long your AC unit operates effectively. These include the frequency of use, the maintenance of the AC unit, the size, and type of the AC unit, and the manufacturer. The average life of an HVAC unit tends to be anywhere between 8 to 14 years, over which period, you will require air conditioner repair in Cleveland, TN from time to time.

It can be difficult for some homeowners to identify the signs of when they should replace their air conditioner. Fortunately for you, we are going to look at some of the common problems older air conditioning units tend to face which indicate that you should replace them. So, here are the common problems with AC units that will require air conditioner repair in Cleveland, TN.

1.  Bad Air Quality

As an air conditioner starts getting older, it will develop more problems and require regular cleaning. The biggest problem you could face is with mold and mildew, which can cause respiratory issues by traveling through the air transport system. Therefore, when you call in for air conditioner repair in Cleveland, TN, ensure that the air ducts are thoroughly cleaned to reduce the occurrence of respiratory problems caused by pet fur, dander, and dust.

2.  Problems with the Fans

All air conditioning units have two fans, one that helps blow air from inside your home over the evaporator coils to cool down the air, and the other blows air over the condenser of the outdoor unit to discharge absorbed heat. The fans could stop working due to several issues, including damaged motors, excessive debris or dirt, lack of lubrication, and worn belts. This can result in restricted airflow, which can lead to air conditioner compressor failure if not dealt with. You should call in for air conditioner repair in Cleveland, TN before the compressor fails. Otherwise, you’ll need to buy a new air conditioner.

3.  Ice Buildup on Evaporator Coils

When you’re using a lot of electricity and when there is extreme heat, you may notice ice building up on your air conditioning unit. This can mainly be caused by dirty air filters that prevent the circulation of air around the evaporator coils of the unit. However, if there is ice on the evaporator coil, it could mean a more serious problem, like a failing condenser, refrigerant leak or a broken fan.

4.  Wear and Tear

One of the best ways to avoid air conditioner repair in Cleveland, TN is through regular maintenance of your AC unit. However, even if you have taken great care of your AC unit, its performance will start to deteriorate over time. When you factor in the severe weather of Cleveland, TN and natural chemicals in the air, the mechanical and electrical parts of your AC unit will start to wear out over time.

5.  Electrical Failures

When your air conditioner starts aging, its chances of suffering an electrical failure also increase. The common electrical problems your HVAC unit could face include circuit breakers frequently tripping, failing capacitors, and relays sealed shut and forced open. Apart from that faulty wiring may also cause electrical failures. Additionally, if your HVAC unit hasn’t been properly maintained and is being overworked, it can burst up in flames.

6.  Refrigerant Leaks

You may have a refrigerant leak if the HVAC unit is always on low refrigerant. If that is the problem, then adding more refrigerant won’t solve anything. Refrigerant leaks not only affect the performance of the HVAC unit but are also harmful to the environment. The leak can be fixed easily if it is in the refrigerant line, but if it’s located in the compressor, you should think about buying a new HVAC unit.

7.  Inefficiencies

Apart from general wear and tear, your air conditioner could be performing less efficiently than a new HVAC unit because of being damaged in some way. It could be because of the fans, compressor, or coils. Most of these issues will result in your air conditioner working harder and will impact the way it will cool your home, which will mean higher energy bills.

8.  Duct Leakage

With the passage of time, breaks or holes may start appearing in the ducts inside the walls, which carry cool air into the rooms of your house. This could be down to the age of the unit, which will result in the sealing cracking and letting air escape. Closing the vents for extended periods can also cause holes and cracks, because of air pressure buildup.

Apart from that, insects, rodents, or birds may start nesting in the ductwork, which can restrict airflow. Rodents can create holes in the duct by chewing them, and that will cause uneven cooling in the house. This will also cause the HVAC unit to work harder for cooling the home, which leads to higher energy costs. Leaking ducts may also cause a dirty air filter, debris buildup in the system, and air quality problems that could damage the air conditioner.

9.  Leaking Water

Cleveland, TN is known for its excessive humidity, which can lead to condensation build-up in older AC units with condensate drains. The drains can get blocked or clogged when there is too much water and the overflow pan is missing or damaged. This will result in water backing up, which will damage your AC unit. Apart from that, water leaks can also damage your walls, ceilings, and furnishings, and can lead to mold growth. When this happens, you may need to acquire air conditioner repair in Cleveland, TN to fix the problem.

10.  Sensors Misaligned

The sensor of the thermostat found behind the control panel of your HVAC unit can become misaligned after several years of use. This will cause your AC to start up and shut down repeatedly, making your home too cool or too hot. You could suffer long-term problems due to these erratic cycles, which is why you should get air conditioner repair in Cleveland, TN to fix the problem immediately.
