The short answer
ChillPro AC Repair handles air conditioner, heat pump, and furnace repairs throughout Santa Clara County, from Palo Alto and Mountain View to Los Gatos and Milpitas. Bay Area Air District rules don't require replacing working equipment, so repairing a sound system is often a reasonable choice.
ChillPro AC Repair is based in San Jose and repairs air conditioners, heat pumps, and furnaces for homeowners across Santa Clara County. Whether your AC quits on a hot afternoon in Los Gatos or your furnace won't light on a damp winter morning in Palo Alto, we find the cause, explain your options in plain terms, and fix what can reasonably be fixed.
Common HVAC Problems We Repair
Most service calls come down to a handful of issues. We check the whole system, not just the part that failed, so the same problem is less likely to come back.
- AC running but not cooling, or blowing warm air
- Frozen evaporator coils or ice on refrigerant lines
- Furnaces that won't ignite, short-cycle, or shut off early
- Heat pumps stuck in one mode or struggling to keep up
- Failed capacitors, bad contactors, and tripped breakers
- Thermostat problems and wiring faults
- Weak airflow from clogged filters, blower issues, or leaky ducts
- Water leaks from clogged condensate lines
How the Valley's Climate Affects Your System
The Santa Clara Valley has a Mediterranean climate, with dry summers and mild, damp winters. Inland and southern parts of the valley run noticeably hotter in summer than areas near the Bay, so an air conditioner in Saratoga or Los Gatos often works harder than one in Mountain View or Milpitas.
That difference shows up in repairs. Systems in hotter areas tend to put more wear on compressors and capacitors, while homes closer to the Bay may run their AC less but lean on heating through the cooler, wetter months. We consider how your system is actually used before recommending a fix.
Repair or Replace: What Local Rules Mean for You
Bay Area Air District appliance rules do not require you to replace working equipment. They apply only when an existing furnace or water heater fails or is replaced. If your furnace can be repaired safely, keeping it running is a valid choice.
Planning ahead still helps. Under Rule 9-4, natural gas furnaces manufactured from 2029 must meet a zero-NOx emission standard, which in practice points homeowners toward heat pumps when replacing a furnace after that date. The small water heater date under Rule 9-6 was set for 2027, but the Air District Board is considering amendments in November 2026 that could delay it, so check the current rule before planning a water heater replacement.
The federal 25C tax credit is not available for heat pumps installed after December 31, 2025. BayREN and your local clean energy provider may offer heat pump and electrification incentives, but availability changes by funding cycle, so we confirm the current offer before including it in a quote.

What to Expect When You Call
We start by asking what your system is doing and when the problem began. On site, the technician tests the system, identifies the cause, and walks you through the repair before any work starts. If replacement makes more sense, we explain why and lay out your options, including whether a heat pump suits your home.
