In most parts of the United States, like West Virginia, summer temperatures get high and being stuck without an air conditioner can be unbearable. For optimal comfort and to keep your AC unit running efficiently, it’s best to know the most common air conditioner problems, so you can catch them before they turn into a disaster.

Refrigerant Leaks

Refrigerant leaks are a common summer air conditioner problem. Since refrigerant is what helps remove the heat and humidity from your home when a leak occurs, your AC system can’t run efficiently, and it won’t be able to keep your home cool and comfortable.

Unfortunately, you can’t just add more refrigerant. To fix a refrigerant leak, you need a trusted HVAC technician to find the leak, repair it, and have your AC unit up and running again.

Clogged Drains

AC units create condensation as they work, which typically isn’t a problem because it’s usually removed via the condensation drain. Unfortunately, sometimes the condensation drain becomes clogged, leading to water backup and leaks that can damage your AC system and create an unwanted musky smell in your home. If these leaks go unnoticed, they can eventually lead to mold growth and damage your walls, ceilings, and floors.

Duct Leaks

The ductwork in your home carries the cool air and disperses it for even cooling and comfort in all rooms, but if there are holes or breaks in the duct, this cool air will leak out. When your ducts leak and you lose cool air to your walls, your AC unit works harder while your home remains uncomfortable.

Dirty Air Filter

The more your AC unit runs, the faster your air filter will get clogged. A clogged air filter can lead to a lack of cooling, air flow problems, a shortened life span for your system, and more. Luckily, avoiding this summer air conditioner problem is an easy fix; all you have to do is check and replace your air filter at least once a month.

Not only is replacing your air filter essential to a functioning AC unit, but this simple solution can also lower your systems energy consumption by 5% to 15%.

Frozen Evaporator Coils

Your AC systems evaporator coils are packed with refrigerant, and they work to absorb heat. To work correctly these coils need warm air circulating them, but sometimes airflow problems lead to the air around evaporator coils getting too cold, leading to ice build up that doesn’t allow them to do their job. This can lead to hot air or no air being blown out of your AC unit.

Dirty Condensor Coils

When there’s too much build up on your condenser coils, they can’t function properly in removing heat from your home. This leads to low efficiency and makes it so that your system has to work harder to keep your home comfortable, substantially shortening its lifespan and leading to higher electricity bills.

Fan Issues

Your ac unit generally has two fans, one that works to blow the indoor air over evaporator coils to cool it, and another fan that blows air over the outdoor condenser so that hot air can be removed from your home and sent outside. If either of these fans stops working properly, your entire AC unit can’t do its job.

Fan issues can arise from motor problems, worn belts or other parts, a lack of lubrication, a build-up of dirt and debris, and more.

AC Unit Constantly Turns On and Off

Your AC unit should turn on and off to save energy, but if it’s doing so constantly, then it’s a sign of a common air conditioner problem. Many things like dirty condenser coils, evaporator coils, or air filters can lead to this air conditioner problem. This problem can also be caused by an AC unit that is too small for your home or faulty or loose wiring.

AC System Won’t Turn On

If your AC unit doesn’t turn on, chances are you have a power problem, and it’s as easy a fix as checking your electrical panel for a tripped breaker or blown fuses. It’s also a good idea to check wires for any damage or issues. Sometimes this air conditioner problem may also be caused by a damaged thermostat that needs to be repaired or replaced.

Your AC Unit is Too Loud

All AC units make some sound, but if your system is louder than usual, it might mean that it’s time to have your ductwork, fans, and exterior vents checked and cleaned. Often accumulation of dust and debris is enough to cause your AC to be louder than usual, while also putting a strain on the unit. There’s also the chance of a rodent or small animal clogging the system somewhere along the lines.

AC System is Blowing Warm Air

We know how frustrating it can be when your air conditioner does exactly the opposite of what you want. An AC unit blowing out warm air can be caused by many things, like an improperly set thermostat, refrigerant leaks, frozen parts, blown breaker, broken compressor, and more.

  1. My house seems dusty lately and the ac unit is blowing extra hard without actually cooling more. I will try to replace the filter and see if that helps, if not it’s time for the repairman to come out and take a look. I never knew that you should change the filter once a month and that it can really help with energy savings.
