Repair vs Replace Your Commercial HVAC System

The success of your business is largely dependent on the comfort of your employees, clients, customers, and guests. If your HVAC system isn’t working properly, it can create an uncomfortable environment that decreases productivity, deters clientele, and increases utility costs. If the problem persists, it can cause irreversible damage to your system, which can lead to premature replacement. For all these reasons and more, it is important to recognize the signs that it’s time to have a professional service your HVAC system.

Common signals that you require commercial HVAC services include:

  • Disruptive noises, such as humming, squealing, clanking, or buzzing
  • Too much moisture inside your business
  • Unpleasant odors throughout your property
  • Visible signs of malfunction
  • Problems with thermostat controls
  • Inconsistent room temperatures
  • Short cycling of your system
  • Water or refrigerant leaking from the HVAC unit
  • Energy bills that are higher than usual
  • Equipment is nearing the end of its lifespan

When to Replace Your Commercial HVAC Equipment

Unfortunately, commercial HVAC systems, either traditional ones or ductless mini split systems, don’t last forever. At some point, you will need to invest in new equipment for your property. While repairs may be an adequate remedy early in your system’s life, eventually replacing the unit will be the more cost-effective option. It’s important not to replace your system too soon, but you also can’t afford to wait too long.

In general, we recommend replacing your commercial HVAC system when:

  • Your equipment is more than 15 years old
  • The system fails to maintain a comfortable temperature
  • The unit has experienced a significant amount of wear and tear
  • Your system requires frequent repairs
  • The cost of repair is more than 50% of the price of a new unit

If you are not sure about the proper time to replace your HVAC system, you can always call our expert repair team. Our technicians are trained to accurately diagnose the source of the issue and advise you on whether repair or replacement is the best option. Give us a call today at 703-483-2400.
