Four months of hard running in St. George heat
Your air conditioner in Washington County works one season a year, but it works hard. From June through September, with afternoons averaging 90°F, the compressor runs long hours to keep the house cool. That kind of run time wears on the parts that keep it going, the capacitor, the contactor, the coil.
Washington County has also seen its share of hail and wind, seven hail events and 60 damaging wind events over the past ten years, with hail up to 1.75 inches. A unit sitting outside can take a hit to its fins or cabinet without you knowing it until the day it needs to run. A tune-up before summer checks the refrigerant charge, tests the capacitor, and looks over the coil and cabinet for damage, so a problem gets caught before the system has to work through another season with it.

A tune-up checks the refrigerant charge, cleans the coils, tests the capacitor and tightens the electrical connections.
Utah requires HVAC contractors to hold a state license.
Utah licenses HVAC contractors through the Division of Professional Licensing. That license covers the contractor, not each job. Work under $7,000 does not need a licensed contractor, so whether that protection applies at all depends on what the job costs.
Maintenance on an air conditioner is usually well under that amount, so the license may not be the thing standing behind this visit. What does apply, regardless of cost, is the EPA Section 608 certification. Any technician who opens the refrigerant side of the system, even to check pressures during a routine visit, has to hold that federal certification. It is not a state license and it does not depend on the size of the job.

- What does AC maintenance include?
- A technician checks the refrigerant charge, cleans the condenser coil, and tests the capacitor and contactor in the outdoor unit. Inside, they check the evaporator coil, inspect the blower, and confirm the thermostat is calling for cooling correctly. They also check the filter and look at the condensate drain, since a clogged drain can back up and cause water damage. Anyone opening the refrigerant side of the system has to hold EPA certification, so that part of the job always falls to a qualified technician.
- How often does an air conditioner need maintenance?
- Once a year, before the season it works hardest. Here that means getting it checked before June, since the unit runs steadily from June through September with afternoons averaging 90 degrees. A yearly check catches a weak capacitor or a low refrigerant charge before it fails on a hot afternoon instead of after.
- Is AC maintenance worth it?
- Yes, because most AC failures trace back to something a technician would have caught. A dirty coil makes the compressor work harder, and a weak capacitor eventually strands the fan motor, and both show up in a routine check before they cause a breakdown. With four months of real cooling demand here, a unit that goes into June already strained is a unit likely to quit when it's needed most.
