HVAC systems are designed to last for decades if they are properly maintained. Biannual inspections from an air conditioning service company will find and repair any issues or broken parts, but knowing how to recognize common issues with HVAC systems can help you get ahead of unexpected problems, especially during the hot Arizona summer. Here are some of the most common problems you may encounter and how to know when you should call your local air conditioning repair contractor.

What Are Frequent Issues With HVAC Units?

1. Room-Temperature Air

If your air conditioner is only blowing lukewarm air, there could be a problem with the filter, compressor, or circuits. Another likely culprit is low refrigerant levels. Because refrigerants don't typically deteriorate, low levels indicate a possible leak, and refrigerant levels might gradually drop as a result of slow leaks. 

2. Blown Fuses

One of the most typical causes of a circuit breaker trip in a furnace is an overworked blower. If something is obstructing your system's airflow, your blower will have to work harder than usual. A clogged air filter is the most likely cause, forcing the blower's energy consumption to rise. If changing the filter doesn't solve the issue of blown fuses, have a contractor inspect it for other sources of mechanical malfunction.

3. Condensate Trouble

Your air conditioner's evaporator chills the warm air that passes through it, causing moisture to drop out of the air. The condensate drain pan collects all this moisture and directs it to a drain via the condensate line. The heat in Arizona can cause a variety of issues with this HVAC element, including rust or damage that leads to water dripping into your home. 

4. Loud Noises

A noisy air conditioner can be an annoying issue. If you hear banging or rattling sounds from the AC, dirt particles might have gotten stuck in the condenser. Screeching noises may indicate an issue with the fan motor or the belt, while pulsating sounds may occur because of a loose coil or fan blade. On the other hand, hissing is often an indicator of a compressor valve or refrigerant leak. Have an air conditioning repair contractor examine the unit to determine the exact cause of the noise and repair the issue before it can worsen and cause greater damage to your AC.
