Our AC Repair Process in Lafayette
Diagnose Why It Is Not Cooling
We check the whole system — refrigerant, capacitor, coils, airflow, and controls — to find why your Lafayette AC is not keeping up, instead of guessing.
Explain the Fix
We show you what is wrong and give you clear, upfront pricing on the repair, or an honest replacement recommendation if the system is beyond its life.
Repair & Recharge
Our licensed techs make the repair, fix any refrigerant leak properly rather than just topping it off, and restore full cooling.
Test & Tune
We confirm the system cools correctly and can set up an annual tune-up to prevent the next hot-weather breakdown.

What Affects AC Repair Cost in Lafayette
The cost of AC repair or installation in Lafayette depends on the system and the issue, and we quote it upfront before we start. The main factors are:
- The specific repair — a capacitor is minor, a compressor or coil is major
- Whether a refrigerant leak needs to be found and sealed
- Repair versus full system replacement
- For installs, the size, efficiency (SEER), and type of new system

Air Conditioning Repair in Lafayette — Frequently Asked Questions
Common causes are low refrigerant from a leak, a failed capacitor, a dirty or frozen coil, or a bad compressor. Before you call, replace a dirty filter and clear debris from the outdoor unit — then call 862-860-1807 if it still will not cool.
An annual spring tune-up is ideal. It catches small problems before the heat arrives, keeps the system running efficiently, and lowers your energy bills through the Lafayette summer.
If the system is more than 10 to 15 years old, needs a major repair like a compressor, or uses phased-out refrigerant, replacement is often the smarter long-term choice. We give you an honest recommendation for your Lafayette home.
A frozen AC usually means restricted airflow (a dirty filter or coil) or low refrigerant. Running it while frozen can damage the compressor, so shut it off and call 862-860-1807 — it needs professional diagnosis.
