A functional AC is essential for your home. When it shows signs that it's no longer operating at an optimal level, it may be time to repair or replace it. After all, with an efficient HVAC system, you can always have cool or heated air throughout the year. Here are some tips to know when it's time to call an AC contractor.

Musty Smells

You should feel your AC unit working, not smell it. If you begin to smell musty or moldy odors, it's a sign that your unit needs a professional cleaning or replacement. The ducts can acquire dust, dirt, contaminants, allergens, and mold when they haven't been properly serviced. Calling an AC contractor can ensure that your home's air is properly filtered, and you're not breathing in these nasty elements.

Excessive Noise

The only thing worse than a smelly HVAC system is a very noisy one. Is it difficult to have a telephone call or watch TV when you have your AC on? Be mindful of rattling, shaking, or loud humming noises. After all, a functioning AC should make a low humming sound that will resemble white noise. Such humming certainly isn't a noise that should be disturbing to your overall peace.

Poor Air Circulation

Do you have to stand under your unit to feel something? If so, that's a sign that it's not circulating the way it should be. A unit that can't properly circulate air throughout your home is pretty useless. Your AC contractor knows what to look for to ensure that your air is flowing as it should.

High Energy Bills

Are you afraid to open your electrical bills these days? As your HVAC system ages, it may need extra energy to function. The more energy your HVAC system uses, the greater the electrical bills you'll have. It may be time to replace your unit with something more energy-efficient.

According to Brookings, roughly 70% of American homes have central AC. These are just some reasons why a homeowner may need to call upon a local AC contractor. Looking out for these signs can keep your home cooled and heated as needed. It can also ensure you have solid air quality, circulation, and reduced energy bills.
