Book Your Appointment TodayA family-owned HVAC company built on 15+ years of hands-on work.
U M Air Inc. is a California-based mechanical contractor operating out of Downey since 2009, with over 15 years of hands-on experience delivering HVAC and building systems for residential, commercial, multi-family, and hospitality clients across Southern California.
We have grown from local residential service calls into a trusted mechanical partner for general contractors, architects, and developers on complex, large-scale projects, including corporate campuses, hotels, and multifamily developments, without losing the hands-on, customer-first approach we started with.
Whether it is a single-family home or a ground-up commercial build, the goal has not changed since day one: engineering-sound HVAC solutions that perform reliably, improve your indoor environment, and keep energy costs in check.
