Rooftop Equipment
Rooftop Unit Repair in Dallas and DFW
Package rooftop units carry most of the conditioning load for retail strips, office parks, and warehouses across DFW, and they take weather that indoor equipment never sees. We service package RTUs from 3 to 50 tons, working through compressor faults, economizer failures, and stuck actuators without pulling the unit off the curb unless replacement is the right call.
- Same-day and next-day service calls
- Chiller plants up to 500 tons
- All major brands
What's covered
Compressor diagnostics and repair
Amp draw and pressure testing to determine whether a compressor is failing mechanically or being starved by another fault.
Economizer and damper repair
Fixing stuck or miscalibrated economizer dampers that waste energy or let unconditioned air into the space.
Actuator replacement
Replacing failed damper and valve actuators that stop the unit from modulating outdoor air properly.
Belt-drive blower service
Adjusting or replacing belts, pulleys, and bearings on blower assemblies to restore correct airflow.
Gas ignition and burner checks
Servicing the gas heat section of dual-fuel and gas-electric package units, including ignitors and flame sensors.
Common symptoms
Facilities usually call about one or more of the following before a tech is ever dispatched.
- Unit cycles the compressor on and off in rapid succession
- Economizer damper stuck fully open even when outdoor air is too hot to use
- Rattling or grinding noise from inside the cabinet on startup
- Roof curb showing signs of water intrusion around the unit base
- Airflow noticeably weaker at diffusers than it used to be
- Unit trips on high pressure during the hottest part of the afternoon
- Gas heat section fails to ignite on the first several attempts
How the visit works
- 1 Rooftop inspection
We access the unit, check the curb and cabinet condition, and pull panels to inspect the compressor, economizer, and blower sections.
- 2 Component testing
Actuators, contactors, and pressure switches are tested individually to find the specific part causing the fault.
- 3 Repair or advise replace
If the unit is repairable, we complete the fix on site. If age and repair cost point toward replacement, we walk through that option honestly.
- 4 System verification
The unit runs a full cooling and heating cycle before we consider the call complete.
Equipment we service
Our techs carry diagnostic tools for equipment across manufacturers rather than specializing in one brand. Equipment we service includes:
Related services
Commercial HVAC repair
Facility managers call us when a unit stops cooling, stops heating, or trips a breaker and nobody on staff can tell why.
Maintenance AgreementsPreventive maintenance
Most commercial breakdowns trace back to something a scheduled visit would have caught: a clogged drain pan, a slipping belt, a coil packed with debris.
Ductwork & Air QualityDuctwork & ventilation
Air handling equipment can be running perfectly and a building can still feel stuffy or uneven if the duct system moving that air is leaking, undersized, or out of balance.
Available across Dallas and Fort Worth
This service runs on the same routes as the rest of our work, across the following areas.
Common questions
What size rooftop units do you service?
We work on package RTUs from roughly 3 tons up to 50 tons, covering the range typical of retail, office, and light industrial buildings.
Can you fix an economizer that will not close?
Yes, stuck economizer dampers usually trace to a failed actuator or a linkage that has come loose, both of which we repair on site.
Do you handle the gas heat side of package units, not just cooling?
Yes, our techs check ignitors, flame sensors, and heat exchangers on gas-electric and dual-fuel rooftop units during the same visit.
Is it ever better to replace a rooftop unit than repair it?
Sometimes. When a compressor or heat exchanger fails on an older unit, replacement can make more sense, and we will tell you honestly which way the numbers point.
Tell us about the equipment and the symptom, and we will get a technician scheduled.
