Frequently asked questions

Common causes include low refrigerant (often from a leak), a faulty compressor, a clogged condenser, electrical issues, or a blend door problem. We can diagnose the issue and recommend the appropriate repair.

We recommend an A/C performance check annually, ideally before summer. Refrigerant levels can drop over time, and catching small issues early prevents expensive repairs.

Most vehicles made before 2015 use R-134a refrigerant. Many newer vehicles (2015+) use R-1234YF, which is more environmentally friendly. We service both types.

Common causes include low coolant, a faulty thermostat, a clogged heater core, a malfunctioning blend door, or air in the cooling system. Since your heater uses engine heat, heating problems can also indicate cooling system issues.
