Rooftop Unit Replacement & Service
Rooftop units handle heating and air conditioning for most commercial buildings, and they take a beating from Portland rain and summer heat. We repair, maintain, and replace them.
Signs your unit needs attention
- Rising energy bills with no change in use
- Uneven temperatures across the space
- Frequent breakdowns or tripped breakers
- Rust, leaks, or water pooling on the roof
- A unit older than 15 years
If your unit shows two or more of these signs, our technicians can inspect it and tell you whether a repair or a replacement makes more sense.

Frequently Asked Questions
How is commercial HVAC different from residential?
Commercial systems run longer hours, serve more people, and often sit on the roof. They need equipment, controls, and service schedules built for business use.
Do you offer emergency HVAC service for businesses?
Yes. When your heating or air conditioning fails, call or text (503) 612-6677 and we will get a technician to your business as quickly as possible. We offer same-day service for many repair calls.
How often should a commercial HVAC system get maintenance?
Most businesses need service at least twice a year, before each heating and air conditioning season. Busy kitchens and high-traffic spaces often need more frequent visits.
Can you work on my system without shutting down my business?
We plan work around your business hours and tell you upfront if any part of the job requires downtime.
How long do rooftop units last?
Most rooftop units last 15 to 20 years with regular maintenance.
Do you service equipment you didn’t install?
Yes. We service all major brands, no matter who installed them.
What areas do you serve?
We serve businesses in Portland, Beaverton, Lake Oswego, Tigard, West Linn, Tualatin, and the surrounding metro area.
