You Don't Have To Make The Same Mistakes

I always took my home's heating and cooling system for granted. That is until I found myself battling one of the hottest days in years and my air conditioner simply refused to turn on. After contacting my local HVAC contractor, I learned that my cooling coils had frozen over from a lack of maintenance. He did get my AC back up and running that day, but he also helped me to look at my heating and cooling system in a whole new light. I have spent a lot of time over the last few years learning more about how to properly maintain my HVAC system and ultimately lower my energy costs. Today, I would like to share this knowledge with you so that I can help you to avoid some of the costly mistakes I have made in the past.

Things That Go Bump in the Night Could Include Your Furnace

Halloween is a special occasion filled with scary stories and scary costumes, but the scariest thing to any homeowner is a furnace that suddenly starts making strange noises. These strange and spooky sounds can frighten any homeowner, especially when the bill comes due for putting them to rest. To get to the bottom of these strange sounds, you'll need to know what's causing them in the first place.

Warped Blower Fan

Your furnace blower fan's one and only job is to move air throughout the furnace and its ductwork. Any sort of physical damage can hinder your blower fan's operation and make a big racket in the process. For example, a bent fan blade can strike the surface of the blower fan housing, causing a harsh banging or clanging noise that intensifies depending on fan speed.

Blower fans can also lose their balance due to physical damage or improper installation. This can cause wobbling that also allows the fan to strike the housing and make noise. If your blower fan is belt-driven, a loose belt can also cause similar noises.

Loose Fasteners

Whenever you hear rattling from your furnace, chances are there is a loose bolt or screw somewhere that needs tightening. If you or a technician forgot to tighten down the furnace door after previous maintenance, you could hear rattling the next time you start up your furnace. Entire duct panels can also make a buzzing or rattling racket when they come loose.

If you know what's causing your furnace to rattle, take the time to tighten the offending fasteners. If these noises continue afterwards, have your HVAC technician check out the problem and pinpoint the source of the noise.

Worn Bearings

Most of your furnace's moving parts require bearings to reduce friction and facilitate effortless movement. Worn bearings can make your furnace scream like a banshee. That might sound cool to the trick-or-treaters at your front door, but it's no fun for anyone in your home. Mechanical shrieking noises are common from worn bearings, but you could also hear grinding noises, too.

Worn bearings can also cause friction, which in turn causes excess heat that could further damage affected components. So if you hear any of the aforementioned noises coming from your furnace, shut it off and have your HVAC technician inspect the problem and make the appropriate repairs. In most cases, your HVAC technician will simply replace the failed component altogether.
