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.

Improve Air Quality with Better HVAC Maintenance

by Billie Carlson

Indoor air quality is so important for your overall quality of life. If you have allergies, then you rely on good air quality so you can breathe comfortably at home. Even without allergies, breathing in a lot of dusty, dirty, or really humid air is not enjoyable. There are lots of ways to improve air quality, from installing an air purifier to vacuuming more often. But simply maintaining your HVAC equipment can go a long way, too. Here are the three key ways to improve air quality via HVAC maintenance.

Pick a Better Filter

Every forced-air HVAC system needs a filter to remove particulate matter from the air. But there are cheap, flimsy filters and more expensive, good filters. You don't need to spend a fortune on the best filters available. But upgrading from the cheap, flimsy fiberglass filter will certainly improve your air quality. Low-level fiberglass filters don't do a great job of trapping smaller particulate matter, like dust mites and mold spores. Pleated cotton filters do a better job, and electrostatic filters are even better than that.

Also, make sure you replace your filter often enough. Replacing it once a month is smart, in most cases.

Clean Your Ducts

When a furnace or air conditioner is replaced, the existing ductwork is usually left in place. So, the ducts in your home could be decades old. If they have not been cleaned in that time, they are likely littered with dust, pet dander, and other debris. You can't really clean ducts on your own; you need to hire an HVAC service to do that. Doing so will instantly improve your air quality and will probably get rid of any nasty odors in your home, too.

Have Your Coils and Burners Cleaned

There are two parts of your HVAC appliances that really need to be cleaned: your AC coil, and the burner in your furnace. These both tend to build up dust and grime over time, and that debris gets spread through the home. Although some people do DIY these cleaning tasks, it's best to have them done by a pro since mistakes you make could damage your equipment. 

If you want to improve your indoor air quality, contact an HVAC and furnace maintenance company. Chances are, they will recommend the measures above, and they can directly help you with the duct cleaning, burner cleaning, and coil cleaning aspects of this HVAC maintenance.
