Stay comfortable year-round in your vehicle with expert climate control service from our team. Whether summers bring serious heat or winters dip below freezing, a properly functioning A/C and heating system isn't a luxury — it's a necessity. Our experienced technicians diagnose and repair every part of your climate control system to keep your cabin at the temperature you set.

Complete A/C and Heating Services

We handle everything from A/C refrigerant recharges, compressor replacements, and condenser repairs to heater core service, blend door actuators, and blower motor replacements. Our technicians use UV dye and electronic leak detection to find refrigerant leaks that can be difficult to spot visually. Whether your A/C blows warm air on a hot afternoon or your heater can't keep up in winter, we'll get your system working properly.

Signs Your Climate Control Needs Attention

Many drivers tolerate a gradual decline in A/C or heating performance, assuming it's normal. It's not. If your A/C takes longer to cool the cabin, blows warm intermittently, or produces a musty smell, there's a fixable issue. On the heating side, slow warm-up times, cold air from the vents, or a foggy windshield that won't clear are all signs of a problem worth addressing before it gets worse or affects your visibility and safety.

Frequently Asked Questions

Why is my car's A/C blowing warm air?

The most common cause is low refrigerant due to a leak, but it can also be a failing compressor, a clogged condenser, or an electrical issue. Our technicians will diagnose the exact cause and provide a clear estimate before starting any work.

How often does my A/C need a recharge?

A properly sealed A/C system shouldn't need regular recharging. If your system is low on refrigerant, there's likely a leak that should be repaired. We use electronic leak detection to find and fix the source.

Can you fix my car's heater?

Yes. We repair all components of the heating system including heater cores, blend door actuators, blower motors, and coolant control valves. Heating issues often relate to the cooling system, which we also service.
