AfterFast, Reliable Furnace Repair Across Palo Alto

We’re Brandt HVAC, and we know Palo Alto’s heating systems inside and out. From the Eichler tracts in Greenmeadow and Fairmeadow to the pre-war Craftsman homes along Waverley Street in Old Palo Alto, we’ve repaired furnaces in every corner of this city. Our technicians are dispatched from our San Francisco Bay Area office, so we’re never far when your heat goes out on a cold January morning. Palo Alto’s mild winters mean most homeowners don’t think about their furnace until it fails. That’s when you need someone who understands the local housing stock, the permitting quirks, and the specific failure modes this climate produces.
Why Brandt HVAC Is Palo Alto’s Preferred Furnace Repair Company
Palo Alto homeowners choose us because we tell you exactly who is coming to your door. Under our Threshold Verified standard, every technician is background-checked and identity-verified. You get a name, photo, and bio before anyone arrives. The technician shows a photo ID badge at your door. If anyone shows up who you weren’t told to expect, that visit is on us and we make it right.
Our Furnace Repair team has built a strong local reputation across Palo Alto neighborhoods. Homeowners in Duveneck/St. Francis and Crescent Park regularly mention our upfront pricing and the 365-Day Done Right Promise in their feedback. We’re part of the Threshold Group family, established in 2003, and each Brandt HVAC location is independently owned and operated.
Response time matters when your furnace quits. We keep parts in stock for the brands Palo Alto homes run most: Trane, Lennox, Goodman, and Rheem. Most repair calls are same-day. Our phones are staffed by a live person 24/7. No voicemail, no callback queue, no automated phone trees.
Local knowledge separates a quick fix from a proper repair. We know that Eichler radiant systems in Greenmeadow often mask furnace problems for years, and that Old Palo Alto’s original gravity systems throw static pressure readings that confuse less experienced techs. We account for this before we touch a tool.
Gas Furnace Repair in Palo Alto
Gas Furnace Repair in Palo Alto covers everything from failed ignitors and cracked heat exchangers to gas valve failures and blower motor burnout. Most Palo Alto homeowners call us when they notice cold air from vents, a burning smell, or a furnace that won’t fire at all. Typical repairs run $150 – $700, parts and labor included, with a written price before any work starts.
Heat Exchanger and Ignitor Failures
Cracked heat exchangers are serious. They can leak carbon monoxide into your home. If we find one, we show you the crack with a camera, explain your options, and give you a written price for replacement or full system conversion. Ignitor replacements are more routine. Most gas furnaces in Palo Alto use hot-surface ignitors that fail after 5 – 7 years. We stock Lennox and Goodman ignitors for same-day replacement.
Blower Motor and Gas Valve Problems
A failing blower motor often starts as a humming noise, then progresses to intermittent operation or total seizure. We test amp draw and capacitor health before condemning the motor. Gas valve failures are less common but more urgent. If your furnace fires briefly then shuts off, or won’t fire at all despite a good ignitor, the valve may be sticking or the pressure regulator may be out of spec.
Furnace Tune Up in Palo Alto
Furnace Tune Up in Palo Alto is a full-system inspection, cleaning, and safety check that keeps your gas furnace running efficiently through the heating season. We recommend it annually, ideally in early fall before the first cold nights hit. A tune-up runs $80 – $200 and includes a written report of everything we find. Our technicians are not paid on what they sell, so the report is honest, not a sales pitch.
What the Tune-Up Covers
We pull and inspect the burners, check flame sensor output in microamps, test gas pressure at the manifold, measure temperature rise across the heat exchanger, and inspect the blower wheel for dust buildup. In Palo Alto’s Eichler homes, we also check whether radiant slab leaks have been forcing the furnace to overwork. We clean what we can, flag what needs repair, and give you a written summary.
Safety Checks Specific to Local Housing
Older homes in Crescent Park and Old Palo Alto often have original venting or add-on ductwork that doesn’t meet current code. We check for backdrafting, carbon monoxide spillage, and proper combustion air supply. If we find a safety issue, we explain it plainly and give you options. No scare tactics. Just facts and a written price.
Trusted Brands We Service in Palo Alto
We service all major residential HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Palo Alto customers, we stock common failure parts for Trane, Lennox, Goodman, and Rheem locally. That means faster turnaround on most repairs. If you have a Daikin system in an Eichler retrofit, we carry those parts too. Our technicians are trained on each manufacturer’s diagnostic protocols, not just generic troubleshooting. When we arrive, we already know your system’s common failure modes.
Common Furnace Repair Problems We See in Palo Alto Homes
- Radiant slab leaks masking furnace failure. In Greenmeadow and Fairmeadow Eichlers, pinhole leaks in embedded copper tubing force the gas furnace to overwork for years before any fault code appears. By the time the homeowner calls, the heat exchanger is often corroded beyond repair.
- Undersized ducts starving the blower. Original forced-air systems in Old Palo Alto and Crescent Park Craftsman homes have ducts sized for 1950s equipment. Modern blowers fight against high static pressure, overheat, and fail prematurely. We measure static pressure before blaming the motor.
- Short-cycling from oversized equipment. Palo Alto’s mild heating loads mean some homes have furnaces that are too large for the actual demand. The system heats the house quickly, shuts off, then restarts minutes later. This wears components and wastes gas.
- Failed ignitors in aging systems. Most Palo Alto furnaces installed in the 1990s and 2000s use hot-surface ignitors with a finite lifespan. They fail without warning, usually on the first cold morning of the season. We keep replacements in the truck.

FAQs About Furnace Repair in Palo Alto
HOA and neighborhood screening rules in Greenmeadow and Fairmeadow can delay replacement jobs if crews skip approval before scheduling. We always confirm outdoor condenser placement and line-set routing with the relevant association or city planning before we order equipment. For simple repairs that don’t alter exterior appearance, approval usually isn’t needed. Call (984) 538-9003 and we’ll tell you whether your job requires pre-approval.
Yes, we repair the gas furnace even when radiant tubing is present. The furnace often serves as backup or handles zones the slab doesn’t reach. We also diagnose whether slab leaks have been damaging the furnace. In the Greenmeadow tract, we recently capped failed radiant loops and commissioned a multi-zone Daikin mini split with concealed line sets to satisfy flat-roof aesthetics. The homeowner cleared CPAU electrification paperwork before we set the outdoor condenser, so nothing sat on the truck waiting.
Short-cycling usually means the furnace is oversized for Palo Alto’s mild heating load, or the thermostat is in a poor location. The diurnal swing here – cold 50°F nights after warm afternoons – exaggerates the problem. We measure run times and temperature differentials to confirm the cause. Sometimes a simple thermostat relocation or blower speed adjustment fixes it. Other times, right-sizing the equipment is the only real solution.
Yes, furnace replacement requires a permit from the City of Palo Alto. This is especially important because Palo Alto is served by City of Palo Alto Utilities (CPAU), not PG&E. CPAU’s electrification rebates and carbon-neutrality mandate actively push furnace replacements toward all-electric heat pump conversions rather than like-for-like gas swaps. We handle the permit paperwork and help you navigate CPAU rebate programs if you’re converting to a heat pump. Call (984) 538-9003 for details.
Once a year, in early fall before heating season. Palo Alto’s mild climate means furnaces don’t run hard, but that can mask developing problems. Annual tuning catches heat exchanger cracks, gas leaks, and blower issues before they become dangerous or expensive. Our tune-up is $80 – $200 and includes a written report. Call (984) 538-9003 to schedule.
