“Alpha Mechanical was great! We had a faulty coil. They were able to diagnose the leak and replace it within a couple days from when we called. Their communication and fast response is better than any other company's we have tried in the past.”
Sean Finegan
Verified Google review“We scheduled a tune-up for our HVAC and joined their membership. The employee was very nice, easily explained what needed to be done and answered all my questions! Really grateful to have the tune-up completed before summer!”
Sara Wicks-Johnson
Verified Google review“Andre was polite, responsive, and quick. Same-day service during this heat was a lifesaver. Highly recommend. Front desk was very kind and professional too.”

Sacramento neighborhoods we work in every week
- East Sacramento
1920s Tudors and colonials in the Fabulous Forties and bungalows around McKinley Park and River Park, most with little or no original ductwork. Ductless mini-splits and careful coil cleaning under the tree canopy are the common calls.
- Land Park
Tudors near William Land Park, Tower District bungalows and South Land Park ranch homes. Older plaster and tight attics make a mini-split the usual answer where ducts were never run.
- Curtis Park
A streetcar-era neighborhood of 1910s–1930s bungalows and Tudors on tight lots around the park and the Sierra 2 Center. The same crew every visit, and no tearing into plaster to add cooling.
- Natomas
North and South Natomas are mostly 1990s–2000s tract homes on flat former farmland. Builder-grade capacitors, contactors and condenser fan motors are past warranty now, and that is what fails first.
- Arden-Arcade
Half the homes date from the 1950s and 60s, so the ductwork under a typical ranch house is older than any furnace it has carried. Our shop is on Fair Oaks Boulevard, the same road that runs into Arden-Arcade.
- La Riviera
1960s–70s ranch housing along La Riviera Drive and the American River Parkway on aging ducted systems. Tired compressors, R-22 refrigerant and leaky ducts are the usual culprits.
