Your HVAC system works hard every single day. Gilroy HVAC keeps it running with expert repairs, right-sized replacements, and maintenance plans built for local homes.
When the system quits, you want a company that shows up fast and fixes it for good. Our experienced HVAC technicians cover the whole area with stocked trucks, straight answers, and quality work.
Two systems do most of the work in a typical home, and they're the two we repair most. Here's what to expect when you call.
Most air conditioner breakdowns trace back to one failed part: a weak capacitor, a burned contactor, a seized fan motor, or a slow refrigerant leak. We diagnose it with gauges and meters, not guesswork. Every repair comes with an upfront quote and an honest opinion on repair versus replacement.
A furnace that won't light on a cold night can't wait until morning. Most no-heat calls come down to a dirty flame sensor, a failed igniter, or a blower motor, and our trucks carry the common parts to fix them on the spot. We also check for the problems that matter for safety, like a cracked heat exchanger, and give you an upfront price before any work begins.
Whatever your system needs, a quick fix, a smart upgrade, or a full replacement, our team covers it start to finish with workmanship that lasts.

Call (408) 694-4630Wondering if it's bad enough to call? These are the most common heating and cooling problems we solve in homes across the area.
Low refrigerant, a failed compressor start, or a dirty condenser can all masquerade as the same symptom. Real diagnosis beats parts-swapping every time.
AC repairA furnace that lights and then shuts down within seconds usually has a dirty flame sensor or a failing igniter, quick fixes for an experienced tech.
Furnace repairThat slow decline in performance isn't age, it's neglect compounding. A proper clean-and-tune brings most systems back to spec in one visit.
Maintenance & tune-upsWhen repair bills start stacking up, a modern high-efficiency system often costs less per month than keeping the old one alive.
System replacementYour ducts move the same air thousands of times a day. Years of dust, dander, and construction debris ride along until they're cleaned out.
Air duct cleaningAdditions and bonus rooms rarely get enough duct capacity. A dedicated ductless head fixes the problem permanently.
Mini-split installationMost repair calls are diagnosed and fixed in a single visit because we stock the common parts, capacitors, contactors, igniters, motors, on every truck.
We don't cut corners. Our team is experienced, background-checked, and fluent in every major brand, from a 20-year-old gas furnace to the newest inverter-driven heat pump.
Plenty of companies sell a new system the moment yours hiccups. We diagnose first, explain what actually failed, and only recommend replacement when the math genuinely favors it.
We don't just swap the failed part. We check what killed it, airflow restriction, voltage, refrigerant charge, drainage, and correct that too, so the same failure doesn't repeat next season.
Year after year, Gilroy HVAC has been the team local families call when the AC quits or the furnace goes cold. We've serviced systems in nearly every neighborhood around town, and that track record shapes how we approach each job, from the first diagnostic to the final test.
Our team goes beyond the quick patch. We know the failure patterns, duct issues, and code details common to local homes and businesses. This local knowledge means faster diagnosis, fewer repeat visits, and systems that last.
Talk to someone who actually knows heating and cooling. Honest, no-pressure pricing over the phone.
Every job runs through the same proven steps, so nothing gets missed and the fix actually lasts.
Pick up the phone and dial (408) 694-4630. A few quick questions later, your appointment is on the calendar, frequently the same day.
We inspect the whole system, not just the obvious symptom, and give you a straight answer: what failed, why, and what repair versus replacement really costs.
We complete the approved work on the spot whenever possible: quality parts, code-compliant connections, and no shortcuts hidden behind the air handler.
The job isn't done until conditioned air is flowing and verified. We'll also show you the simple habits, and offer the maintenance schedule, that add years to the system's life.

Speed matters when the temperature is climbing or dropping. This is the sequence our team runs through, from the moment your call comes in to the moment your system is running again.
The first call is where it all starts. Someone on our team picks up, works out how urgent the situation is, and schedules the soonest visit available, while telling you the few simple things to do in the meantime.
There's no waiting around for days. A fully equipped technician pulls up to your home, often same-day, with the parts already on board to diagnose and start fixing right then.
The technician confirms exactly what failed and why, then fixes it on the spot, and if the system is beyond saving, walks you through right-sized replacement options with real numbers and a realistic timeline.
Seasonal maintenance runs on your schedule, so you never have to think about it, to keep efficiency up and failures down. A maintained system lasts years longer and runs cheaper every month.
"Half our house was always five degrees warmer than the thermostat said. The tech found crushed flex duct and a dampener stuck half-closed, then set up a new smart thermostat and actually taught us how to use it. The whole house is finally even."
"The furnace kept short-cycling, kicking on and off every few minutes and never really warming the house. The technician diagnosed an overheating issue in minutes and sorted it in one visit. It runs like new now, and he showed me which filter to buy going forward."
"We put a ductless mini-split in the bonus room over the garage that was always freezing in winter and roasting in summer. They measured and calculated instead of eyeballing it, and the install was clean and quick. That room is finally usable year-round."
We treat your home the way we'd treat our own: thoroughly, honestly, and with an eye on the long term. Here's the standard you can count on from us every time.
Real experience isn't optional on our team. It means every technician reads refrigerant and electrical faults correctly, installs to local code, and explains the work in plain language at a level most companies don't reach.
We size every replacement to your home's real heating and cooling load rather than defaulting to whatever's on the truck. Installations include the details that matter: sealed duct connections, correct line sets, proper condensate handling, clean electrical work. You get a system that performs for years, not just on day one.
Our team believes in keeping systems alive with simple, scheduled care. If you want to avoid the emergency replacement, our spring and fall maintenance visits clean coils, verify the charge, and test every safety control. No surprises, no hidden fees. This approach is why so many homeowners recommend us.
