Minimize Disruption
Work is scheduled around how your stores trade — off-hours, staged, and sequenced so a repair or a replacement does not cost you a selling day. Keeping the location running is the job, not a courtesy.
Creating comfort since 1987
Family-owned commercial HVAC for California and Arizona businesses
A second-generation family business that maintains, repairs and replaces rooftop HVAC for multi-site retail portfolios. 35+ years in, still headquartered in Temecula.
Five words, used as a decision rule
What are REE Mechanical's S.A.B.E.R. core values?
Safety, Accountability, Balance, Elevate, and Respect are the criteria REE hires against — and the ones a technician is expected to apply on a roof at 6am with nobody watching.
- 01
SAFETY
Think Safe, Be Safe, Live Safe
- 02
ACCOUNTABILITY
Doing What I Said I Would Do, When I Said I Would Do It
- 03
BALANCE
Being available for you
- 04
ELEVATE
Level up through growth, innovation and empowerment
- 05
RESPECT
Treating others as they want to be treated
Our mission Doing whatever it takes to make a difference in the lives of everyone around us.
Our passion Be the hero for our family, co-workers, and clients.
REE Mechanical hires against these five values and trains weekly, in house. If they describe how you work, see our commercial HVAC technician jobs at REE Mechanical .

How we operate
Three commitments REE Mechanical makes on every job
Minimize Disruption, Eliminate Red Tape, and Built to Adapt are commitments a facilities director can hold REE to, because each one is either true on the invoice or it is not.
Eliminate Red Tape
IVR check-in, work-order platforms, and close-out documentation are handled inside your systems and scoped to ANSI/ASHRAE/ACCA Standard 180: National Standard Practice for the Inspection & Maintenance of Commercial HVAC Systems — a published standard, not a frequency we made up — so the compliance trail your department is measured on stays intact without you chasing paperwork.
Built to Adapt
Commercial only, with technicians trained weekly across all makes and models — so an unfamiliar package unit on an unfamiliar roof, anywhere across a multi-site portfolio, is a normal day rather than a special request.

When the answer is not a repair
HVAC rental partners for temporary cooling
When equipment is on back order or a store cannot go dark, REE often rents temporary cooling rather than installing a unit — through rental partners like Herc Rentals in Southern California.
