Thermalair Inc

Thermalair Inc has operated continuously in Anaheim since 1948, earning a California contractor license (102216) spanning boiler, HVAC, and refrigeration classifications, plus a Nevada license (0042848) for refrigeration and air conditioning. The firm holds dual union affiliation with UA Local 250 and SMART Local 105, and its workforce carries MSCA and UA trade certifications. Across seven published reviews the company averages 2.1 stars, placing its reputation below area competitors. Corporate headquarters sit at 1140 N. Red Gum Street in Anaheim, with a listed phone number of (714) 630-3200 reachable Monday through Friday during standard business hours.

A LEED green-building specialty anchors Thermalair Inc's commercial identity, with engineers performing load calculations, performance-based energy modeling, and computational fluid dynamics analysis. The firm leverages Revit BIM modeling for pre-construction trade coordination, clash detection, and robotic layout work, capabilities rarely found at mid-size contractors. Mobile technicians deliver 24-hour service covering cleaning, diagnostics, and part replacement, targeting prolonged equipment life and reduced downtime across Montage Beverly Hills and Emerson Ford Theater projects.

Several reviewers directly tied substandard experiences to how Thermalair Inc vehicles operate in the field. Mackenzie Cosgrove described a middle-aged female driver who nearly struck her and an infant in a parking lot without slowing or apologizing. Daniel Frederick reported a technician driving recklessly on public roads, prompting him to rule out future hiring. Ryan Molina was compelled by property management to accept a $1,500 site survey, followed by a $14,000-plus ductwork proposal for a space under 3,000 square feet, a figure he found excessive relative to alternatives he subsequently located.
