Hot weather can arrive quickly and without warning in Quincy, IL, and Hannibal, MO. When it does, you change the thermostat to “cool” and forget about it. That is, until you realize that the air conditioner is still blowing hot air. What’s going on here?

Refrigerant Leaks

Low refrigerant levels are typically caused by tiny leaks in the refrigerant lines. The leaks can cause an air conditioner to hiss and gurgle. If refrigerant leaks are corrected promptly, the lost refrigerant can be replenished, and the leaks can be sealed. Without the proper amount of refrigerant in the system, it cannot produce the cool air you want.

Compressor Failure

The compressor is the heart of a cooling system. A failing compressor loses the ability to turn itself on to provide cool indoor air. You might hear ticking, clicking, rattling and chattering if the motor has a loose part. If the compressor motor fails, it won’t even start.

Blocked Air Filter

HVAC filters are easily overlooked when troubleshooting an ailing air conditioner. But when the filters become clogged, your system has a hard time pulling in air to cool. Clogged filters cause excessive wear and tear on the entire cooling system. Check and change your air filters about every three months, perhaps more frequently if you have furry pets. Clean filters will protect your air conditioner from grime and keep indoor air clean and fresh.

Condensate Line Obstruction

Clogged condensate drains are easy to fix if you are something of a DIY-er. The drain line provides an exit through which moisture collected from indoor air can drain out. If the line isn’t cleaned regularly, algae and mold can form a clog. If the water can’t drain out, it can back up and trip the drain pan float switch which turns off your AC so the water doesn’t overflow into your garage or house. The drain line will need to be cleaned out with a shop vac, and a mild bleach or vinegar solution poured down the line to the outside of the house. If you’re unfamiliar with this, please call us and we’ll be happy to help.
