Rooftop Unit (RTU) Service in Leawood, KS
The packaged rooftop unit is the workhorse of commercial HVAC — one cabinet on the roof that handles heating, cooling, and ventilation for a zone below. Because it lives outdoors and runs hard, it fails when it’s neglected, and almost always under peak load. 7th Degree Heating and Air services, repairs, and replaces rooftop units across Leawood and Johnson County, with the rooftop access, ventilation know-how, and uptime focus that commercial RTUs demand.
What Makes an RTU Different
A rooftop unit packages everything — compressor, coils, blower, heat, and often an economizer — into one weather-exposed cabinet, which creates its own service realities. The economizer (the damper assembly that pulls in cool outdoor air for free cooling and meets ventilation needs) is a frequent failure point that quietly drives up energy costs when it sticks. Belts and bearings wear and need adjustment. The curb and cabinet have to stay sealed and drained against weather. And all of it sits on a roof, so safe access is part of every visit. An RTU that’s serviced on schedule is dramatically more reliable than one that’s only touched when it quits.

Frequently Asked Questions
- What is a rooftop unit?
- An RTU is a packaged HVAC system mounted on a commercial building’s roof, combining heating, cooling, the blower, and usually an economizer in a single cabinet that serves a zone below. It’s the most common commercial configuration because it keeps equipment off the floor and centralizes service to the roof.
- What are the most common rooftop unit problems?
- Economizer failures (stuck dampers or bad controls that waste energy), worn belts and bearings, refrigerant and electrical faults, clogged condensate drains, and curb or cabinet weather issues. Many start small and show up at a scheduled visit long before they cause a shutdown — which is exactly why RTUs reward regular service.
- How often should a rooftop unit be serviced?
- More often than residential equipment, because RTUs run hard and are weather-exposed. Quarterly or semi-annual service is common depending on run hours and environment. The economizer, belts, and drainage in particular benefit from regular attention — we’ll set an interval based on your specific units.
- Should I repair or replace a rooftop unit?
- It depends on the unit’s age, the failure, and the refrigerant. A belt, economizer, or electrical repair on a sound unit is straightforward. A major failure on an older RTU — especially one using phased-out refrigerant — often favors replacement with a current-standard, more efficient unit. We give you the honest repair-versus-replace comparison with real numbers.
- What does the economizer do, and why does it matter?
- The economizer is a set of dampers that bring in outdoor air when it’s cool enough to help cool the building — “free cooling” — while also supplying ventilation. When it fails stuck, you either lose that free cooling (higher bills) or pull in too much hot air (worse comfort and cost). It’s one of the highest-value things to keep maintained on an RTU.
