Signs your rooftop unit needs attention
If you notice any of these, a quick inspection can prevent a small problem from turning into a full system failure.
- The building is not cooling evenly or not reaching the set temperature
- The unit runs constantly or cycles on and off too often
- Strange noises, vibration or odors come from the unit
- Energy bills climb with no change in use
- Water leaks or ice buildup appear on or near the unit
RTU repair or RTU replacement
A repair makes sense when the unit is otherwise sound and the failed part is a known fix. Replacement is worth considering when repairs are frequent, parts are hard to find or the unit has reached the end of its service life. We lay out both options so you can compare cost and expected life before you decide.
Work done around the unit
Rooftop units depend on the systems around them. Our team can also service the ductwork, controls and ventilation connected to your RTU, so one contractor can look at the whole system. See our pages on HVAC controls and ductwork and ventilation.
