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.

AC Leaking Water? Repair Basics You Should Know

by Billie Carlson

If your home's central air system is leaking water, don't dismiss it as something normal. In fact, leaking water from your air conditioner could be a sign of a serious problem that needs the services of an AC repair technician. When you notice water accumulation around your air conditioner, you need to understand the causes of these leaks so that you can have the problem addressed as quickly as possible.

Condensate Drain Line Clog

Sometimes, air conditioners will leak water because the drain line attached to the condensate pan is clogged with dirt or other debris. When the line gets clogged, the condensation accumulates in the drain pan and then overflows, causing the leak.

You may be able to resolve this yourself by flushing out the condensate drain line, but if that doesn't resolve it, you'll want to talk with an air conditioning repair technician about the issue. They can either replace the drain line or find and clear the clog. Additionally, they can examine the operation of the system to identify what has caused the clog and take steps to prevent it from recurring.

Condensate Pump Failure

If the condensation drain pan is overflowing but you've confirmed that the drain line isn't clogged, the problem could rest in the condensate pump. Larger central air conditioning units have a condensate pump to push the condensation out the drain line. 

When that pump fails, the water won't drain out as it should. That will cause water to accumulate in the drain pan and overflow. You'll want to have an air conditioning repair technician inspect the condensate pump. If it needs replacement, your repair technician can ensure that the new one is properly and safely installed.

Evaporator Coil Problems

The evaporator coils inside your central air conditioner are the key component for removing heat from the air. Unfortunately, when they remove heat from the air, they also generate condensation. If the coils are dirty or frozen, they won't work as effectively as they are supposed to. 

An AC repair technician will inspect the coils of your air conditioner, clean them if they need it, and address any other damage. If the coils are cracked or broken, they will need to be replaced.

It's important that you don't disregard water leaking from your central air conditioner. Not only can water damage be a very real risk, but the inefficiency can prove costly. Additionally, if ignored, it could ultimately lead to complete system failure. Contact an AC system repair service for more information.
