Common AC repairs and what drives the cost
The most frequent calls in Lehi involve a failed capacitor or contactor — inexpensive parts, but the service call still carries a diagnostic charge. Refrigerant leaks cost more because a technician has to locate and seal the leak on an R-410A system before recharging it, and refrigerant prices have climbed in recent years.
Compressor failure is the costliest common repair short of full replacement, and units run hard through repeated 95-100F summer stretches tend to show this failure earlier than in milder climates.
Evaporative cooler repairs vs. refrigerated AC repairs
If your Lehi home still runs an evaporative (swamp) cooler, common repairs include pad replacement, pump failure, and float valve issues — generally cheaper fixes than refrigerated AC repairs, but the unit needs seasonal startup and shutdown service that refrigerated systems don't.
If you're deciding whether to keep repairing an older swamp cooler or convert to central air, factor in that a conversion adds ductwork and electrical costs beyond the unit itself, but gives more consistent performance during Lehi's occasional humid late-summer spikes when evaporative cooling loses effectiveness.
When repair makes sense vs. replacement
As a rule of thumb, if a repair quote approaches a third or more of the cost of a new system, or the AC unit is past 12-15 years old, replacement usually pencils out better given how many peak-heat days Lehi sees each summer.
Permits for repair work
Straightforward part-level repairs generally don't require a permit, but replacing the outdoor condenser, indoor coil, or converting from evaporative to refrigerated cooling crosses into mechanical permit territory with Lehi City's Building and Inspections Division — ask your contractor directly which category your job falls into 1.
Choosing a repair contractor in Lehi
Confirm the technician's company holds an active Utah DOPL S350 HVAC/Mechanical Contractor license and that anyone handling refrigerant carries EPA Section 608 certification. Get a written diagnosis before agreeing to a repair rather than accepting a verbal 'it needs work' estimate.

Common questions
How much does a typical AC service call cost in Lehi?
A diagnostic visit typically runs $80-$170 before any parts or labor for the actual repair are added.
Is refrigerant leak repair worth it on an older AC system?
It depends on system age and how extensive the leak is; on units past 12-15 years old, many Lehi homeowners find replacement is more cost-effective than repeated leak repairs, especially given summer run times.
Do I need a permit for a simple AC repair in Lehi?
Most part-level repairs don't require a permit, but replacing the outdoor condenser or converting from evaporative to refrigerated cooling requires a mechanical permit through Lehi's Building and Inspections Division.
What license should my AC repair technician hold?
Look for an active Utah DOPL S350 HVAC/Mechanical Contractor license plus EPA Section 608 certification for refrigerant handling.
Should I repair or replace my old evaporative cooler?
Simple pad, pump, or float valve issues are usually worth repairing, but a unit past 15-20 years old with recurring problems is often a candidate for replacement or conversion to refrigerated AC.
How often should I service my AC in Lehi's climate?
Given the long, intense summer cooling season, annual spring service before peak heat is standard, and evaporative coolers additionally need seasonal startup and shutdown service.
