3 Common AC Problems That Require Repairs

Your air conditioning generally works without requiring much maintenance, but the system can run into problems that require repair. You shouldn't be living in a home without working air conditioning. Here are three problems that are easy to have fixed by a local HVAC technician.

Warm Air

Troubleshooting an air conditioner that produces warm air can be difficult due to it being the result of of several possible problems. The first part that needs to be looked at is the system's evaporator coil. This part is responsible for producing the cold air that is pushed through your ductwork, and it is essential for making the entire system operational.

If the evaporator coil is functioning properly, the next step is to investigate the coolant running through the system. There could be a leak that is allowing coolant to escape, which will not allow the unit's evaporator coil to get cold enough to cool down the air.

Other potential problems are an air filter that is clogged and not allowing air to pass through, or a blower motor that is not pushing the air through the vents.

No Power

When it looks like the air conditioner is not receiving any power, troubleshooting starts by looking at the circuit breaker. Was a circuit recently tripped and power has been cut off completely? If so, the problem may be as simple as flipping the circuit back on.

With the electricity confirmed to be turned on, other aspects can be investigated to determine the cause for no power. This includes looking at moving parts that could be dead and need replacement, such as the air handler motor or the compressor motor.

Of course, the problem could also be due to a broken thermostat. If the thermostat is not receiving power or transmitting a signal to the air conditioner, it may give the appearance that the air conditioner itself is not receiving power.

Too Loud

While an air conditioner isn't quiet, it should not be so loud that it is a distraction in your home. One reason for loud noises is a problem with the unit's air handler. It could be due to something as simple as a fan belt that needs to be replaced. In some situations, fixing the noise could require replacing parts within the air handler or replacing the entire motor.
