The short answer
If your Gilroy furnace won't start, blows cold air, short-cycles, or makes new noises, a technician can usually trace it to ignition, airflow, sensors, or controls and repair it in one visit. Bay Area Air District rules do not require you to replace a working furnace, so repair is often the sensible first step. ArcticPoint HVAC Repair serves Gilroy and offers 24/7 emergency service.
Gilroy sits at the southern end of the Santa Clara Valley, where summers run hot and winter nights still get cold and damp enough that you want reliable heat. Because the heating season here is short, many Gilroy furnaces sit unused from spring through fall, then get switched on during the first cold snap. That is often when problems show up: a burner that won't light, a blower that runs cold air, or a burning smell that lingers too long. ArcticPoint HVAC Repair is based in San Jose, about 19 miles northwest, and we come to Gilroy homes to find out why a furnace isn't working and fix it. We also offer 24/7 emergency service for nights when the heat quits.
Why Gilroy furnaces fail after the off-season
In much of the South Bay, a furnace may run only a few months a year. Long idle stretches let dust settle on burners and flame sensors, let filters clog without anyone noticing, and give small wear issues time to turn into failures. When the system finally gets called on during a chilly, damp night, weak parts are pushed hard all at once.
Here are the problems we see most often when Gilroy homeowners call for furnace repair:
- Furnace clicks or tries to start but never lights, often a dirty flame sensor or failing igniter
- Blower runs but the air coming out is cool or lukewarm
- Furnace turns on and off every few minutes (short-cycling)
- Rattling, squealing, or banging from the cabinet or ductwork
- A burning-dust smell that doesn't fade after the first hour of use
- Thermostat calls for heat but nothing happens
- Some rooms warm up while others stay cold
What happens during a furnace repair visit
We start by asking what you've noticed: when the problem began, what the furnace does when it tries to start, and whether any error lights are blinking on the control board. Those details often point us in the right direction quickly.
From there, the technician checks the thermostat and its wiring, the filter and airflow, the igniter and flame sensor, the gas valve and burners, the inducer and blower motors, safety switches, and the flue for proper venting. We explain what we found in plain terms, tell you what the repair involves, and get your approval before doing the work. Many common fixes, such as cleaning a flame sensor, replacing an igniter, or correcting an airflow restriction, can be handled on the same visit when the part is on hand.
Repair or replace? What the Air District rules mean for you
Some Gilroy homeowners worry that new regional rules will force them to give up their gas furnace. That isn't the case. Bay Area Air District appliance rules do not require replacing working equipment; they apply only when an existing furnace fails or is replaced.
Looking ahead, natural gas furnaces manufactured from 2029 on must meet a zero-NOx emission standard. In practice, that points homeowners toward heat pumps when a furnace is replaced after that date. If your furnace is in good shape and the repair is reasonable, fixing it is usually the practical choice. If it is aging and needs repeated or major work, it may be worth thinking about your long-term plan now. We'll give you an honest read on the condition of your system so you can decide without pressure.
Incentives and tax credits to know about
If you are weighing a heat pump instead of another round of furnace repairs, note that the federal Energy Efficient Home Improvement Credit (25C) only covered qualifying heat pumps placed in service before December 31, 2025. It is not available for new installations after that date.
Bay Area homeowners can still check BayREN and their local clean energy provider for current heat pump and electrification incentives. Amounts and availability change by funding cycle, so we confirm the current offer before we mention it in any quote.
When to stop and call right away
Some furnace symptoms shouldn't wait for a convenient time. If you smell gas, leave the house and call your gas utility from outside before calling us. If your carbon monoxide alarm sounds, get everyone outside and call 911. For a furnace that has quit on a cold night, repeated shutdowns, or scorching smells, our 24/7 emergency service is available to Gilroy homeowners.
Besides Gilroy, we serve nearby communities including Morgan Hill, Los Gatos, Monte Sereno, Campbell, and Scotts Valley.
