Heat Pump Maintenance & Tune-Ups in Hattiesburg & Wiggins

Your heat pump works harder than almost any appliance in your home. In South Mississippi it cools all summer, then switches to heating as soon as the weather turns. A fall heat pump tune-up from Tri-County Air Service gets it ready for winter before the first cold front arrives.

Our NATE-certified technicians inspect, clean, and test your system so it runs efficiently all season. Learn more about the heat pumps we service and install.

Why Fall Tune-Ups Matter

By October, your heat pump has just come off months of nonstop cooling. Dirty coils, worn parts, and loose electrical connections from that long summer carry straight into heating season if no one catches them.

Heating mode also relies on parts that sat idle all summer, like the defrost controls and backup heat strips. A fall tune-up tests these before you need them, not on the first freezing night.

Fall is also the easiest time to get on the schedule. Book before the first cold snap and you skip the rush of no-heat calls.

What’s Included

Every heat pump tune-up covers both heating and cooling performance. Your technician will:

  • Test the system in both heating and cooling modes
  • Check refrigerant levels and look for signs of leaks
  • Clean and inspect the outdoor coil and clear debris from around the unit
  • Test the defrost cycle so the outdoor unit does not ice over in cold weather
  • Inspect and tighten electrical connections and test key electrical parts
  • Check the backup heat strips and their controls
  • Inspect the indoor blower, check the filter, and clear the condensate drain
  • Confirm your thermostat is reading and responding correctly

When the visit is done, you get a clear summary of what we found. If something needs repair, we explain it in plain language and give you upfront pricing before any work begins.

Benefits of Regular Maintenance

  • Lower energy bills: clean coils and proper airflow help your heat pump use less electricity to keep you warm.
  • Fewer breakdowns: most failures start as small problems we can catch during a routine visit.
  • Longer equipment life: a heat pump that is maintained every year tends to last longer than one serviced only when it breaks.
  • Better humidity control: in our damp climate, a heat pump in good shape keeps your home more comfortable all year.
  • Warranty protection: many manufacturers expect regular professional maintenance to keep coverage valid.

Because your heat pump runs in every season, we recommend two visits a year: one in spring before cooling season and one in fall before heating season.

Every tune-up is performed by a NATE-certified technician and backed by our 100% satisfaction guarantee. Have a gas furnace as well? Our furnace maintenance visit covers that equipment.

Heat Pump Maintenance & Tune-Ups in Hattiesburg & Wiggins FAQs​

Twice a year is best, once in spring and once in fall. Your heat pump runs for both cooling and heating, so it gets more use than a furnace or air conditioner alone.
Most tune-ups take an hour or two, depending on the condition of your system and how much cleaning it needs.
A light layer of frost is normal, and your heat pump melts it off with regular defrost cycles. Heavy ice that does not clear usually points to a defrost or airflow problem, so give us a call.
Heat pumps deliver steady warm air rather than the hotter blasts a gas furnace produces. It still heats your home effectively. If rooms are not reaching your set temperature, schedule a check.
Yes. We are a Carrier Factory Authorized Dealer, and our technicians maintain most major heat pump brands.
