Miguel B.
★★★★★
I have nothing but the highest praise for Juan. He was diligent, knowledgeable, friendly, polite, shared some great info. I had initially hired Airstars to just replace a thermostat in an old oven but ended up purchasing a completely new one. No regrets. They made it painless. Will 100% hire them again for whatever appliance needs.

Frequently Asked Questions We Receive
How much does furnace repair cost in Hayward, CA?
Repair costs can vary based on the issue, but Airstars offers a $69 diagnostic & tune-up special to identify the problem affordably. Most minor repairs range from $150 to $400, while major part replacements will be quoted upfront with no obligation.
How often should I service my AC unit in California?
We recommend professional maintenance once a year, ideally in the spring before the summer heat hits. This keeps your warranty valid and lowers your electricity bill by ensuring the unit runs efficiently.
Do you offer emergency HVAC services on weekends?
Yes! Airstars HVAC provides 24/7 emergency heating and cooling repair across Fremont, Hayward, and San Leandro. We understand that heaters and AC units often break at the most inconvenient times.
What is the most energy-efficient heating system for the Bay Area?
For our mild California climate, Heat Pumps are often the most efficient choice. They provide both heating and cooling in one unit and use significantly less energy than traditional gas furnaces.
