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.

5 Indicator Your HVAC Drain Line Is Clogged

by Billie Carlson

One way to keep your AC running smoothly is by fixing all problems as soon as they occur. Waiting too long can aggravate a minor issue. A common air conditioning problem is a clogged drain line. The drain line is responsible for clearing any condensation coming from the evaporator coils. If unchecked, a blocked drain line can lead to a complete shutdown of the system. 

Seeking plumbing services is crucial when you suspect that your drain lines are clogged. But how can you tell that it is blocked? Take a look at the following pointers.

1. Your AC Is Not Working

An obvious sign that your AC drain line is clogged is when the appliance stops working. After your AC clears condensation in the home, it is collected in a pan before flowing out through the drain line. If the drain is clogged, the appliance stop working until the water clears off. So, when the system fails to turn on, it's likely that the drain line is blocked and needs to be checked by a plumber. 

2. Your Walls Become Wet 

Another clear sign that your HVAC drain line is clogged is wet walls. If the walls behind the system are damp and discolored, the drain line is not draining the water adequately. The discoloration means that the problem has been there for quite some time. So, look for plumbing services before the situation worsens.

3. You See Mold Growing in the Drip Pan

The presence of mold tells you that there is moisture buildup somewhere. As seen from the first point, moisture collected around your home goes to the drain pan and is eliminated through the drain pipe. If the drain pipe is blocked, no water gets out, making it the conducive environment for mold to flourish. So if you check and find mold around the drip pan, hire plumbing services.

4. Your House Has a Musty smell 

Closely related to the previous point is a musty odor. When there is too much mold, or algae build up in your home, the smell will ooze through the ductwork. That is a clear indicator that the drain pipe is clogged. It also means that the water leakage has gotten out of hand and needs to be remedied right away. 

5. You Have a Water Damage Problem

Musty smell and mold are a clear indicator of water damage. However, it is also good to check for other water damage signs and have them fixed. Damages on your foundation coupled with mold growth are pointers that you need plumbing services.

When you have such information, a clogged AC drain will never catch you by surprise, and you will be better positioned to call for plumbing services on time.
