Signs You Need HVAC Repair

Have you noticed something wrong with your HVAC unit? But, you aren't sure what that problem might be? Well, at Del-Air Mechanical Contractors, we have provided you with 3 signs to be on the lookout for in order to avoid complete failure from your HVAC unit.

  • Increased Energy Bill -
    Have you noticed the monthly energy bill steadily going up? This could be due to the HVAC not running as efficient as it did when it was new. With a little TLC and repair, you could have your HVAC running at maximum efficiency.
  • Noises & Smells -
    If you are noticing odd smells or strange noises, don't ignore this. It's typically an early warning sign that your HVAC unit is in need of repair. Burning plastic smell or clanking and screeching noises are all indicators that your unit is in need of maintenance or repair.
  • Old Age -
    As HVAC units get older they won't typically run as well. The normal lifespan of a unit is anywhere from eight to ten years. When your unit reaches these ages, it may be wise to look into investing into a replacement unit.
