AC Repair
When your AC quits in July, you don't want to wait. Bring it to Highlands Auto Center and we'll get your cool air back — often the fix is as simple as a recharge. Call (9
When the air won't blow cold in summer or the heat won't come up on a frozen morning, your day gets miserable fast — and a windshield you can't defrost is a safety problem. Highlands Auto Center keeps Dallas drivers comfortable and their glass clear year-round, and we fix the real cause instead of topping off refrigerant and sending you out to be back in three weeks. Call (972) 233-8882 or book online.
Signs your A/C or heat needs attention
- Air blowing but never getting cold (or never warm)
- Weak airflow on the highest fan setting
- A musty or sweet smell when it runs
- The defroster taking forever to clear
- Knocking, squealing, or rattling at startup
- Cabin temperature drifting hot and cold on its own
We diagnose the real cause first
We don't guess. We check system pressures, test the compressor and electrical side, scan for leaks with the right tools, and look at the heating side too — coolant, thermostat, and flow — then quote upfront.
- Measure high- and low-side pressures
- Leak-detect with UV dye / electronic tools
- Test compressor, clutch, and controls
- Inspect coolant, thermostat, and heater core
What we repair
- Refrigerant recharge with a proper leak check
- Compressor, condenser, evaporator, and lines
- Cabin air filter
- Blend doors and actuators
- Heater core, thermostat, cooling-system repairs
- Electrical and control faults

Frequently asked questions
Why is my A/C blowing warm?
Usually a low charge from a small leak, but it can be the compressor, a clogged filter, or an electrical fault. We test to find the real cause.
Can you fix my heater and defroster too?
Yes — heat issues trace to the cooling system, and we service the whole climate system.
How much does A/C repair cost in Dallas?
Depends on the cause; we diagnose first and quote upfront. Call (972) 233-8882.
How long does it take?
Many A/C and heat repairs are same-day.
Do I need a yearly A/C check?
It's the cheapest way to avoid a breakdown — it catches low charge and small leaks early.
