SwiftAir Conditioning Repair travels from our San Jose base into Alameda County, about 18 miles up the road, to repair air conditioners, heat pumps, and furnaces. We work in Fremont, Newark, Sunol, Union City, Hayward, and Pleasanton. This page explains what we fix, how a repair visit works, and what current Bay Area rules mean if your equipment is near the end of its life.
What We Repair
Most calls we get are for systems that have stopped working or started acting strangely. We find the cause first, explain what we found, and repair the part that failed instead of guessing.
- Central air conditioners that blow warm air, short-cycle, or freeze up
- Heat pumps that won't switch between heating and cooling
- Gas furnaces that won't ignite, shut off early, or trip their safety controls
- Thermostats, wiring, and control boards that send the wrong signals
- Blower motors, capacitors, and fan problems that cause weak airflow
- Refrigerant leaks and drain line clogs that leave water around the indoor unit
What to Expect on a Repair Visit
When you contact us, tell us what the system is doing, when it started, and any sounds, smells, or error codes you've noticed. That helps the technician bring the right parts on the first trip from San Jose.
On site, we check the equipment, find the cause, and walk you through your options before any work begins. If a repair makes sense, we do it. If the system has a bigger problem, we'll tell you plainly so you can decide what to do next.
Repair or Replace? Rules Worth Knowing
Alameda County is covered by the Bay Area Air District, and its appliance rules affect what happens when equipment is replaced. The rules do not require you to replace a furnace or water heater that still works. They apply only when existing equipment fails or is replaced.
Under the Air District's furnace rule, natural gas furnaces manufactured from 2029 must meet a zero-NOx standard. In practice, that points homeowners toward heat pumps for replacements after that date, which is worth knowing if you're deciding whether to repair an aging furnace. For small water heaters, the zero-NOx date was set for 2027. The Air District Board is considering amendments in November 2026 that could delay it, so check the current rule before planning a replacement.
The federal 25C tax credit for heat pumps applied only to systems placed in service before December 31, 2025, so it isn't available for new installations. You can still check BayREN and your local clean energy provider for current heat pump incentives. Offers change by funding cycle, and we confirm what's available before quoting it.
