Is Your HVAC Overworked?

Is Your HVAC Overworked?It’s very possible that you have an overworked HVAC system. For an air conditioner in Florida, working hard comes with the territory. Here in the Sunshine State, the annual cooling season can last fully 9 months. The average Florida A/C runs 2,800 hours per year—about twice as much as units in cooler states. No surprise, then, that the expected service life of a central air conditioner is also shorter here, averaging 8 to 10 years.

An overworked HVAC system usually shows signs that it is straining to carry the weight of the home’s cooling or heating load. Here are some of the signs to look out for:

Declining performance.

Maybe a system that used to keep the home consistently comfortable doesn’t anymore. Unless there are alternate explanations like room additions or other structural changes to the house, the system has likely reached the limit of it’s performance parameters.

Frequent repairs.

While it’s not unusual to require an occasional service call and a replacement part during the average lifespan of an air conditioner, it shouldn’t be a regular event. Frequent breakdowns indicate that excess wear and tear is taking its toll.

Higher costs.

While utility rates do rise, the increase in your monthly cooling/heating expenses should be commensurate with that percentage. If your monthly costs are outstripping the utility rate increases, your HVAC system is running increasingly longer cycles to keep the house comfortable.

In many cases, you can reduce the load on the system by taking proactive steps including:

  • Changing the air filter monthly.
  • Scheduling regular annual preventive maintenance with a qualified HVAC contractor.
  • Increasing the amount of insulation in the house.
  • Reducing duct leakage by having the ductwork inspected and sealed.
  • Sealing air leaks around doors, windows and other parts of the structure.
