Patching an Old HVAC System

When I married my husband ten years ago, I reluctantly agreed to move into the older brick home he already owned. I knew the house was outdated. Unfortunately, I didn’t have any experience renovating an older place. Immediately, I noticed the old central air conditioning unit in the home. After thoroughly inspecting the equipment, I was afraid the ancient unit wouldn’t make it through my first summer in my new place. Thankfully, I was wrong. After ten years, this same air conditioning system is still running smoothly. However, it has received some diligent care from a reputable HVAC contractor over the years. On this blog, you will discover the ways an HVAC contractor can restore an older air conditioning unit.

3 Smells Coming From Your Air Conditioning That You Should Not Ignore

Mary Gonzalez

When things don't smell right, chances are, things aren't right. When your home's air conditioning system kicks on, you shouldn't experience anything more than the feel of clean, refreshing cool air – if your sense of smell is triggered, there's something wrong. Here, you'll find a few things that could be causing your home's air conditioning to smell terribly.

Musty, Mildew, Or Moldy Odors

When moisture finds its way into the HVAC system, things can become stinky pretty quickly. Regular cleanings of the duct work, consistent changes of the filter, and bi-annual system cleanings should help to eliminate the problem.

It could also be that the odors are just being pulled into the home from somewhere else. If you have a damp crawlspace under your home and the ductwork runs through it, the smells could be getting picked up there and released into your home. A crawlspace inspection and waterproofing would be needed to stop the smell – and it shouldn't be put off. If things are getting damp enough under your home to cause the air conditioning to pull the moldy smell up into your home, there is some serious mold growth that will need to be removed and managed.

Burning Smells

The minute you smell anything burning, you must find out where it's coming from. If you've identified the source as the air conditioning unit, head to the breaker panel now and cut the power. That burning smell is telling you that something is wrong. If you continue to use the system, it could catch on fire or, at the very least, cause more extensive damage.

So, if you smell something burning coming from your AC unit, shut off the breaker, grab your phone and get out of the house. Contact the local fire department to have things looked over before returning to your home.

Rotten Eggs

Anytime you smell rotten eggs smelling up your home, get out immediately. That rotten egg odor is caused by leaking natural gas. Call the fire department and head to the utility pole near your home and flip the main breaker on the pole. This will help to ensure that nothing sparks before the fire department arrives to help identify the problem.

Talk with a local air conditioning service to learn more about the odors that can come from your home's heating and cooling system. He or she will provide you with all of the information that you need to keep your family safe throughout the year.
