A/C & Heating Repair

A/C & Heating Repair In Denver

A system that blows warm in July or cold in January is usually telling you something specific. We find out what, instead of just topping it up and sending you away.

What We Do

Climate Control, Diagnosed Properly

Air conditioning that has lost its charge has lost it somewhere. Simply refilling the refrigerant sends the same gas back out through the same leak — and vents it into the atmosphere on the way.

We test pressures, trace leaks and check the electrical side and the blower before recommending a repair, so the fix lasts past the first hot week.

Warning Signs

Symptoms Worth Checking

Air Is Not Cold

The most common cause is low refrigerant — which means a leak somewhere in the system.

Weak Airflow

Little air from the vents usually points to a blocked cabin filter or a failing blower motor.

No Heat In Winter

Cold air from the heater can be a thermostat, a coolant level problem or a blocked heater core.

Bad Smell From Vents

A musty odour when the fan starts generally means moisture and growth in the evaporator or filter.

Noise When A/C Is On

Rattling or grinding that appears only with the A/C engaged often means the compressor or its clutch.

Only Works Sometimes

Intermittent cooling points to an electrical fault, a pressure switch or a clutch on its way out.

Questions

Frequently Asked

Still not sure? Call and describe what the vehicle is doing — we will tell you what it is likely to be.

Because refrigerant does not get used up — if it is low, it has escaped. A recharge without leak repair is temporary. We find the leak first so you are not paying for the same gas twice.

Yes, briefly, every few weeks. It keeps the compressor seals lubricated and helps clear the windscreen faster. It also stops the system seizing from disuse.

A diagnosis and recharge is usually same-day. Component replacement depends on the part and where it sits — some are behind the dashboard, which takes longer. We will be clear about this before starting.

Yes. Heating and air conditioning share the same climate control system, and we work on both — blowers, heater cores, thermostats, controls and coolant faults.
