The short answer
ArcticPoint HVAC Repair diagnoses and repairs gas furnaces, heat pumps, and related heating components in Los Altos homes, with 24/7 emergency service available. Air District rules do not require you to replace a working furnace, so repair is often a reasonable choice. If replacement does come up, we explain how upcoming furnace standards and current incentives may affect that decision.
Los Altos winters are mild by most standards, but cool, damp nights from late fall through early spring still put a home's heating system to work. When a furnace won't light, a heat pump blows lukewarm air, or the system short-cycles every few minutes, you want a clear explanation and a fix that holds. ArcticPoint HVAC Repair serves homeowners throughout Los Altos (94024) from our base in San Jose, about 20 miles southeast. We diagnose the actual cause, explain your options in plain terms, and let you decide what makes sense for your home.
Heating Problems We See in Los Altos Homes
The Santa Clara Valley's Mediterranean climate means heating systems often sit unused for months, then run steadily once the damp winter weather arrives. That start-and-stop pattern can expose problems that built up quietly over the summer: dust on burners and flame sensors, weak igniters, clogged filters, and thermostats that drifted out of calibration.
Many homes in the area have equipment of different ages, and some have older ductwork or systems that were added onto during remodels. These are the issues homeowners call us about most often:
- Furnace clicks or tries to start but never lights
- Burners light, then shut off after a few seconds
- Heat pump runs but the air from the vents feels cool
- System turns on and off too frequently (short-cycling)
- Some rooms stay cold while others overheat
- Unusual noises such as banging, squealing, or rattling
- A burning smell that lingers past the first few minutes of the season
- Thermostat is blank or doesn't respond to changes
What Happens During a Heating Repair Visit
We start by listening to what you've noticed: when the problem started, whether it's constant or intermittent, and anything that changed recently. Then we inspect the system methodically instead of guessing. On a gas furnace, that typically means checking the igniter, flame sensor, gas valve, pressure switches, inducer motor, blower, limit switches, and control board. On a heat pump, we check refrigerant performance, the defrost cycle, the reversing valve, outdoor coil condition, and electrical components.
Once we find the cause, we explain it in plain language and walk you through the repair options before doing any work. If we notice something that isn't urgent but is worth watching, we'll tell you so you can plan for it, without pressure to fix it today.
Repair or Replace? How Bay Area Rules Fit In
A common question is whether new Bay Area Air District rules mean you have to get rid of your gas furnace. They don't. The appliance rules do not require replacing working equipment. They only apply when an existing furnace fails or is replaced.
Looking ahead, gas furnaces manufactured from 2029 on must meet a zero-NOx emission standard. In practice, that points homeowners toward heat pumps when they replace a furnace after that date. If your furnace is aging and needs a major repair, this can be useful context: a reasonable repair may keep it running for years, while a large repair on a very old unit might be a good moment to compare options.
If you're weighing a heat pump, note that the federal 25C tax credit is not available for installations after December 31, 2025. Homeowners can still check BayREN and their local clean energy provider for current heat pump and electrification incentives. Those programs change by funding cycle, so we confirm the current offer before including it in any quote.
When to Call, Including Emergencies
ArcticPoint offers 24/7 emergency service. Call right away if heat goes out on a cold night and someone in the home is vulnerable to the cold, or if your carbon monoxide alarm sounds. If you smell gas, leave the house first and contact your gas utility or 911 from outside, then call us for the repair.
For less urgent issues, such as uneven heating or a system that's getting louder, scheduling a visit early usually means a simpler fix and fewer surprises when the coldest weeks arrive.
