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.

Subtle Indicators That It Is Time To Call An Expert For AC Repair

by Billie Carlson

Air conditioning is an essential element of a building. The system keeps the air cool when it's properly running. Besides that, it removes any microscopic particles suspended in the air, such as soot, dust, and allergens. It also provides constant and adequate ventilation and maintains suitable indoor humidity levels. 

On the other hand, a failing unit can lead to discomfort and significant health problems. Furthermore, failure to fix mechanical issues on time could result in expensive repairs or a replacement of the entire unit. This article looks at the signs of a failing air conditioner and how your AC repair technician can fix them. 

Unpleasant Sounds and Smells

Typically, a healthy air conditioner produces low-level noise when running. Therefore, squeaking and grinding sounds or loud and sudden noises are an indication that something is not okay. The noises usually occur when an internal component has become loose. 

On the other hand, unpleasant smells like burning rubber and smoke point to electrical issues. In addition, the smell of mildew could indicate that your filters are clogged and need to be replaced. Therefore, call your AC repair technician when you detect unfamiliar noises or odors from your unit. 

Leaking Water and Increased Humidity

Moisture around the air conditioning unit could signal a faulty compressor. It will encourage mold and mildew growth if you do not address it promptly. Additionally, an increase in the indoor humidity levels also points to compressor failure. You will also notice that the system blows hot air as the compressor deteriorates.

Limited Airflow and Stuffiness Inside the House

When the system has clogged ducts or a failed compressor, the volume of air streaming through the vents is reduced. This means that the cool air getting into rooms is restricted. As a result, you'll experience persistent stuffiness in your home. Repairing the components and cleaning the air ducts can help restore airflow in all the rooms.

A Spike in Energy Bills

When the air conditioning system is faulty and overworking, it will use more energy. Therefore, a substantial increase in your energy bills could be a result of your malfunctioning AC. So to avoid exorbitantly high power bills, call your AC repair technician to find the root cause of the problem. 

You shouldn't ignore these signs or anything unusual in your air conditioning unit. Instead, schedule an immediate appointment with your AC repair technician. Timely repairs avert additional problems and an expensive replacement.
