What HVAC Repair Covers
When the house is not heating or not cooling, the cause is usually a small set of parts: a failed capacitor, a dirty coil, a bad igniter, a starved filter. Technicians carry those parts on the truck, so a large share of HVAC repairs finish on the first visit.
Tune‑ups catch the same issues before a mid‑August no‑cool or a January no‑heat. If the unit is not worth repairing, we say so and walk through replacement instead of patching it indefinitely.

As a rule of thumb, if the system is under 10 years old and the repair costs less than roughly a third of a new install, repair usually makes sense. Past that, especially with an aging refrigerant type or repeated breakdowns, replacement is often the better long‑term value — we'll walk you through the actual numbers for your system.
A tune‑up covers coil cleaning, refrigerant charge check, electrical connection inspection, filter replacement, thermostat calibration, and airflow testing. It's the single best way to avoid a breakdown during a heat wave or cold snap.
This usually points to a refrigerant issue, a failing compressor, a dirty coil restricting heat transfer, or in furnaces, an ignition or gas valve fault. It needs an in‑person diagnostic to pin down — running it longer without repair risks compounding the damage.
Yes — our residential Maintenance Plan starts at $199/year and includes scheduled tune‑ups plus priority booking. Commercial Maintenance Plans start at $245/year. See our Prices page for details.
