Grinding, Squealing and Screeching: Interpreting the Noises Your HVAC Makes

If something is failing or going amiss with your HVAC unit, chances are, your HVAC unit is letting you know something is not quite right. However, most of the cues come in the form of sounds that many of us may overlook. If you hear your HVAC unit grinding, squealing, screeching or squeaking, it is letting you know it needs help. I was unaware of these cues and overlooked them. It ended up costing me a lot of money in repairs. I want to make sure that does not happen to other people, so I made this website. I hope you learn how to interpret the noises your HVAC unit is making so you can get it the repairs it needs before you incur a costly repair, or worse, permanently ruin your unit for good.

Reasons Your AC Breaks Down In Hot Weather And The HVAC Repairs That Might Be Needed

by Billie Carlson

When it gets hot outside, especially when there's a heatwave, you need air conditioning. Air conditioning is important for health reasons for many people, and even if stifling heat and humidity don't harm your health, you'll be miserable when your AC goes out. You'll need fast help from an HVAC repair company. Here are common reasons for air conditioner malfunctions and repairs your HVAC could need.

The Refrigerant Is Leaking Out

A heatwave is a bad time for a refrigerant leak. Your AC won't be able to keep up with your demand for cool air when the refrigerant is low. The HVAC company will test the refrigerant level if they think that's the problem. A gauge reading lets them know if a leak is present or not. If so, the leak will probably need to be plugged before the refrigerant is filled so the new refrigerant won't leak out too.

The Condenser Capacitor Is Bad

Heat is hard on a capacitor. If your condenser is in full sun, the intense heat inside the condenser could cause the capacitor to fail. When that happens, the fan motor and compressor may strain when trying to start. The fan and compressor may not start at all, and that keeps your home from cooling down. A worse situation is when the fan motor or compressor burns out due to a bad capacitor. Then those parts will need to be replaced in addition to replacing the capacitor.

The Blower Motor Burns Out

When there's a heatwave, your AC may not be able to keep up even when all the parts are working. The AC may run all the time trying to meet the temperature setting on the thermostat. When it's really hot outside and your AC runs all the time, it's a good idea to turn up the thermostat even though your house will be warmer. This gives your blower and other parts a chance to shut off and cool off.

If the blower motor burns out, the motor needs to be replaced. When the blower doesn't work, cool air won't circulate through your house, so your house will get hot fast. The HVAC repair professional may need to replace the capacitor along with the motor to make sure your AC will function properly once it's turned back on.

The AC Might Be Leaking Water

The indoor portion of your AC pulls condensation out of the air when air is pulled into the air handler and blows over cold refrigerant coils. When it's very hot and humid, more condensation than normal may be produced. The condensation drain system should be able to handle the extra water by draining it outside.

However, if there's a clog, the extra water may not drain out fast enough. This causes water to spill on the floor. Some systems shut your AC down when this happens so water damage is prevented. The HVAC repair person can fix this problem by clearing the clog and resetting the AC.
