Commercial Rooftop Unit Repair in Maryland
If your business has a box on the roof, that’s a packaged rooftop unit. When it fails, the dining room, the retail floor, or the office fails with it. Chason Service Engineers repairs and replaces light commercial RTUs throughout central Maryland. Same-day on most calls. 24/7 emergency.
Problems we see every week
- No cooling in summer, no heat in winter
- Unit runs but the building never catches up
- Short cycling — on and off every few minutes
- Tripped breakers, bad capacitors, failed condenser or blower motors
- Refrigerant leaks and compressor failures
- Economizer stuck open or closed
- Thermostat and control board issues
- Water on the roof or in the ceiling from a clogged drain
- Loud rattling, banging, or screaming from the unit
Repair or replace
If the unit can be repaired at a fair price, we repair it. If the compressor is gone and the cabinet is 15–20 years old, we tell you replacement is the cheaper path. No scare tactics. You get the numbers before we start.
Brands
Carrier, Trane, Lennox, Goodman, Rheem, Bryant, York, and other packaged rooftop brands common on Maryland shops and restaurants.

FAQ
How fast can you get to a dead rooftop unit?
Same-day on most calls. After hours we treat commercial no-cool / no-heat as emergency.
Can you work on a unit another company installed?
Yes.
Do you offer maintenance so this doesn’t happen again?
Yes. Seasonal rooftop maintenance is how most mid-summer failures get avoided.
