Commercial AC repair, Dallas-Fort Worth
Commercial AC repair for the no-cool you cannot afford in July.
A rooftop unit blowing warm air in a Texas summer is a tenant complaint waiting to happen. We place you with a commercial tech who finds the cause and gets the cold air back.
Commercial AC repair fixes the reason a rooftop unit stopped cooling: low refrigerant from a leak, a failed compressor or capacitor, a dirty or iced coil, or a control fault. We connect you with a commercial-only Dallas contractor who finds the leak or fault, repairs it, and charges the system to spec, instead of topping off refrigerant that leaks right back out.
What a commercial AC repair covers
- No-cool diagnosis across refrigerant, compressor, coils, and controls
- Refrigerant leak detection and repair, then a correct charge
- Coil cleaning so the unit can actually reject heat
- Capacitor, contactor, and compressor testing and repair
- A written report, including any R-22 units to plan for replacement
Signs your commercial AC needs repair
If you are seeing any of these, the unit needs a commercial tech:
- Warm air from the vents while the unit runs
- Ice on the refrigerant lines or the coil
- The unit runs nonstop but the space keeps warming
- Refrigerant topped off every season (that is a leak)
- A breaker that trips when the compressor starts
In DFW, an undersized charge or a dirty condenser coil shows up the first 100-degree week. We keep AC repair commercial-only and leak-focused, because a unit that gets refrigerant added every summer has a leak nobody fixed, and it is costing you in energy and callbacks.
Common questions
Why does my commercial AC keep losing refrigerant?
Refrigerant does not get used up. If a unit needs regular top-offs, it has a leak. Repeatedly adding refrigerant costs more than finding and fixing the leak, and on older R-22 units it is increasingly expensive. A proper repair locates the leak, fixes it, and recharges to the manufacturer's spec.
How much does commercial AC repair cost in Dallas?
It depends on the fault: a capacitor is minor, a compressor or coil is major. The contractor diagnoses first, shows you the fault, and quotes before any work. If the unit is old and the repair is large, the $5,000 rule helps you decide whether replacement is the smarter spend.
What is the difference between commercial and residential AC?
Commercial AC is usually a roof-mounted packaged unit (an RTU) built for larger loads, multiple zones, and code that homes do not have. It needs techs trained on commercial equipment and controls, which is why we place you only with commercial-only specialists, not a residential company working above its depth.
