CallTrellis HVAC Repair by licensed local pros
Fast air conditioning and heating repair from licensed, background-checked local HVAC technicians.
HVAC repair covers the diagnosis and fix of heating, ventilation, and air conditioning systems: central AC and heat pumps, gas furnaces, air handlers, ductless mini-splits, and thermostats. A proper repair visit starts with a diagnostic (typically $75–150, often credited toward the repair) before any parts are quoted.
The most common failures are electrical: run capacitors, contactors, and control boards. On the heating side, ignitors, flame sensors, and inducer motors top the list. These are same-day fixes for a stocked truck. Refrigerant leaks and compressor failures are the expensive end of the spectrum and where a repair-versus-replace conversation is warranted.
Licensing matters: refrigerant handling requires an EPA Section 608 certification, and most states require a mechanical or HVAC contractor license for anything beyond minor maintenance. Every contractor in our network is licensed for the jurisdiction shown on this page and carries liability insurance.
No heat or no AC? Get a tech today.
A dead furnace in a cold snap or a failed AC in a heat wave is a health issue, not just a comfort issue. Our network techs offer same-day emergency diagnostics, and most common failures — capacitors, contactors, ignitors, blower motors — are repaired on the first visit.

Typical hvac costs
| Job | Typical range | Notes |
|---|---|---|
| Diagnostic / service call | $75 – $150 | Often credited toward the repair |
| Capacitor or contactor replacement | $150 – $400 | Most common summer AC failure |
| Furnace ignitor / flame sensor | $150 – $450 | Most common winter no-heat call |
| Blower motor replacement | $450 – $1,500 | ECM/variable-speed motors at the high end |
| Refrigerant leak repair + recharge | $400 – $1,600 | R-410A; older R-22 systems usually warrant replacement |
| Compressor replacement | $1,500 – $3,000 | Compare against full system replacement if unit is 10+ years old |
Ranges are typical national figures for planning purposes; your written quote from a local contractor is the only binding price. Emergency, after-hours, and insurance-billed work can vary.
Frequently asked questions
How much does an HVAC service call cost?
Most companies charge a $75–150 diagnostic fee, frequently credited toward the repair if you proceed. Emergency after-hours calls typically add $50–150. Always ask whether the diagnostic is credited before booking.
Should I repair or replace my AC or furnace?
A common rule of thumb: if the repair cost times the age of the system exceeds $5,000 (e.g., a $700 repair on a 9-year-old unit = $6,300), replacement usually wins. Systems past 12–15 years, R-22 refrigerant systems, and repeat compressor issues also point to replacement.
Why is my AC running but not cooling?
The most common causes, in order: a clogged air filter, a failed run capacitor (fan or compressor won't start), low refrigerant from a leak, or a frozen evaporator coil. Change the filter first; if that doesn't fix it within a few hours, book a diagnostic.
Are your HVAC technicians licensed?
Yes. Every contractor we refer holds the mechanical/HVAC license required in their state and city, plus EPA Section 608 certification for refrigerant work, and carries liability insurance. License details are provided with your match.
How often should HVAC systems be serviced?
Twice a year: an AC tune-up in spring and a furnace/heating check in fall. Regular maintenance catches failing capacitors and cracked heat exchangers early, keeps warranties valid, and typically pays for itself in efficiency.
