A functioning HVAC is a must for any healthy home. After all, it's responsible for keeping the air properly warm or cool during various seasons. Like anything else in your home, your AC or heater can begin to malfunction. Here are a few signs it's time for immediate HVAC repair.

1. Excessive Noise

When you turn your HVAC on, you should only hear a slight humming noise. The noise should be low enough to where it shouldn't be disruptive. However, if you turn your AC on and it begins to shake and rattle and make so much noise that it's impossible to have a phone conversation or watch TV, you have a problem. A loud noise from your unit is a sign that there may be something wrong with the motor that only an HVAC repair professional can handle.

2. High Bills

According to This Old House, nearly half of the energy used in a standard U.S. home goes toward heating and cooling. You can reduce those bills when you make the right repairs or HVAC replacements. The Energy Star brand in particular has become the standard for green living since their appliances produce a low carbon output and can reduce monthly energy bills.

3. Leaks

As a homeowner, the last thing you want is to see a leak and the resulting water damage that can come from it. However, leaks don't just come from your roof or bad piping. A malfunctioning HVAC unit can also begin to leak coolant or water.

4. Bad Smells

Besides not wanting to hear your HVAC unit, you also don't want to smell it. When you turn on your unit, does it smell like rotten eggs, mildew, mold, or other nasty odors? If so, that's a sign that your filters need changing and may be clogged with dirt and other debris.

5. Age

Do you know how old your HVAC unit is? If it's older than 10 years, it's clearly nearing the end of its life span. According to Bob Vila, a typical AC system lasts for about 10 to 15 years. When your HVAC repair professional inspects it, they'll know if it's time to do another repair or if you should go ahead and replace it.

Keeping up with your HVAC repairs and maintenance can make sure your home is always comfortable and at the right temperature. Paying attention to the above signs will ensure your heating and cooling system is fixed in time. For quality HVAC repair and service, contact Mr. Comfort Heating & Cooling today.
