The short answer
ArcticPoint HVAC Repair fixes furnaces and heat pumps in Monte Sereno homes, with 24/7 emergency service available. We find the actual cause of the problem, repair working systems when that makes sense, and explain how Bay Area Air District rules apply if replacement comes up.
When the heat stops working in a Monte Sereno home, you want a clear answer about what failed and what it will take to fix it. ArcticPoint HVAC Repair handles furnace and heat pump repair for homeowners in Monte Sereno, about 11 miles west of our San Jose base. We diagnose the problem, explain your options in plain terms, and make the repair safely. Heating trouble rarely waits for business hours, so we also offer 24/7 emergency service.
Heating Problems We See in Monte Sereno Homes
The Santa Clara Valley has mild, damp winters, so many heating systems sit idle for months and then run hard during a cold stretch. That pattern exposes weak parts. Igniters and flame sensors that worked last spring can fail on the first cold night. Dust collects on burners and in ductwork over the long dry season. Heat pumps that handle both cooling and heating get little rest at all.
Common calls we answer include:
- Furnace runs but blows cool or lukewarm air
- Burners light, then shut off after a few seconds
- Clicking, banging, squealing, or rattling from the furnace or air handler
- Heat pump stuck in the wrong mode or iced over
- Thermostat calls for heat but nothing happens
- Some rooms stay cold while others overheat
- Frequent short cycling or a tripped breaker
- A burning smell that lingers past the first few minutes of the season
How Our Heating Repair Visit Works
We start by asking what you've noticed: when the problem started, what it sounds or smells like, and whether it comes and goes. Then we test the system instead of guessing. On a gas furnace, that means checking ignition, flame sensing, gas pressure, venting, safety switches, the blower, and the filter. On a heat pump, we check refrigerant performance, the reversing valve, defrost operation, capacitors, and airflow.
Once we find the cause, we explain it and walk you through the repair before any work begins. If a part has failed and can be replaced, we usually make the repair on the same visit when we have the part on hand. If we see another component wearing out, we tell you so you can decide whether to address it now or plan for it later.
Gas Furnace Safety
Many Monte Sereno homes heat with natural gas, and furnace problems can involve more than comfort. A cracked heat exchanger, a blocked flue, or a failed safety control can allow combustion gases to escape where they shouldn't. We inspect venting and check for these issues during heating repair calls.
If you smell gas, leave the house and call your gas utility or 911 from outside before calling us. If your carbon monoxide alarm goes off, get everyone outdoors and call 911. Once the home is safe, we can help find and fix the source.
Repair, Replace, and Local Rules
Most heating problems can be repaired. When a system is older, needs frequent service, or has a major failure such as a cracked heat exchanger, replacement may be the better choice. We'll lay out the tradeoffs and let you decide.
Bay Area Air District rules matter here. They do not require you to replace working equipment. They apply only when a furnace fails or is replaced. Under Rule 9-4, 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, it's worth thinking about this before an emergency forces a quick decision.
On incentives: the federal 25C tax credit for heat pumps covered systems placed in service before December 31, 2025, and isn't available for new installations. BayREN and your local clean energy provider may offer heat pump and electrification incentives. Amounts change by funding cycle, so we confirm the current offer before we quote it.
