Palo Alto’s winter nights can dip into the 30s°F, and when your furnace quits at 2 a.m. in Old Palo Alto or Barron Park, you need someone who actually answers the phone. We’re Northstar Heating & Air, and Daniel personally handles heating and furnace calls throughout Palo Alto, from Professorville’s pre-war bungalows to the ranch homes off Arastradero Road. Most Palo Alto furnace repairs run $175–$825, and we typically arrive same day. Call (855) 600-3322 for a free estimate.
What separates a quick fix from a wasted service call? In this city, it’s knowing whether your home has original wall furnaces, a retrofitted central system, or a heat pump tied into CPAU’s grid. Our Heating & Furnace team has spent a decade working on the exact housing stock you’ll find here.
Why Northstar Heating & Air San Francisco Is Palo Alto’s Preferred Heating & Furnace Company
Daniel Okafor doesn’t delegate your job to a rotating crew. He’s the owner and the lead technician on every Palo Alto call, which means the person quoting your furnace replacement is the same person installing it. That accountability shows in our numbers: 357 customers agree we’ve earned our 4.9-star average through ten years of showing up and doing the work right.
Response time matters in Palo Alto, especially when a failed heat exchanger or gas valve leaves your family without heat. We treat the 94306 corridor, the 94303 pocket near East Palo Alto, and the 94301/94304 zones as our regular service area, not an afterthought. Most calls are scheduled same day or next day.
Local knowledge saves money here. We know which Barron Park ranches still run original Goodman furnaces from the 1980s, and we know Professorville homes often need creative solutions because they were never built for ducted systems. That familiarity means fewer callbacks and faster diagnoses.
We’re also certified on 9 major HVAC brands — Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard — so we don’t hand you off to someone else when we open your utility closet.
Our Heating & Furnace Services in Palo Alto
Furnace Repair in Palo Alto
A furnace that cycles too often, blows cold air, or won’t ignite at all needs immediate attention, especially with Palo Alto’s January lows regularly hitting the mid-30s. Daniel handles furnace repair calls personally, diagnosing everything from failed ignitors to cracked heat exchangers on the spot. Most Palo Alto furnace repairs fall between $175 and $825, depending on the part and whether we need to source a component for an older system. We stock common parts for Trane, Lennox, Goodman, and Rheem units to minimize wait time.
Furnace Replacement in Palo Alto
When a furnace passes 15–20 years or repair costs approach half the value of a new unit, replacement becomes the smarter investment. In Palo Alto, this decision carries extra weight: the city’s building reach codes, layered atop California Title 24, require heat-pump-ready electrical panels on significant HVAC replacements. That means your furnace replacement may need to coordinate with CPAU’s service-upgrade process, not just a standard permit pull. We navigate this with you. A full furnace replacement in Palo Alto typically ranges higher than our repair band, and we’ll give you an exact quote after assessing your home’s load requirements, duct configuration, and CPAU panel status.
Furnace Tune-Up in Palo Alto
Palo Alto’s mild winters mean many furnaces sit idle for months, then get pushed hard during a cold snap. A preseason tune-up catches cracked heat exchangers, dirty burners, and failing flame sensors before they strand you. Our furnace tune-ups run $95–$235 and include full combustion analysis, gas pressure verification, and safety control testing. For homes near the Bay, where salt air can corrode outdoor components faster than inland locations, we pay special attention to condensate drains and venting integrity.
Heat Exchanger Inspection & Replacement
A cracked heat exchanger is a genuine safety hazard — it can leak carbon monoxide into your living space. We don’t treat this as a scare tactic; we treat it as a measurable risk. Daniel uses visual inspection, combustion analysis, and when warranted, borescope examination to verify heat exchanger integrity. In Palo Alto’s older housing stock, especially 1950s–1960s ranch homes in Barron Park with original furnaces, heat exchanger failure is one of the most common reasons we recommend replacement over repair. If replacement is needed, we’ll show you the crack and explain exactly why repair isn’t viable.

Trusted Brands We Service in Palo Alto
We maintain active certifications and parts access for Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Palo Alto homeowners, that means no referral runarounds when we open your system and find a Lennox Elite Series or a Rheem Classic Plus. We stock common ignitors, gas valves, control boards, and heat exchanger components locally, and our relationships with regional distributors let us source less common parts fast. Whether it’s an emergency call or a full system install, you’re dealing with one technician who knows your brand, not a dispatcher guessing from a script.
Common Heating & Furnace Problems We See in Palo Alto Homes
- Failed ignitors in aging Goodman and Lennox units. Many Barron Park and Ventura neighborhood ranches still run furnaces installed in the 1990s. The hot-surface ignitor is often the first component to fail after years of thermal cycling, and it’s a same-day fix when we have the part on the truck.
- Heat exchanger cracks in original 1960s–1970s furnaces. Palo Alto’s mid-century housing stock includes thousands of furnaces that have exceeded their safe service life. We find compromised heat exchangers regularly during tune-ups, and we always recommend replacement — never a patch — because CO exposure isn’t a risk to negotiate.
- Gas valve failures after long idle periods. Furnaces that run only a few dozen hours per year in Palo Alto’s climate can develop sticky or failed gas valves from disuse. We test valve response and gas pressure as part of every service call.
- Undersized or oversized systems from retrofit installations. Homes that converted from wall furnaces to central heating often received systems sized by rule-of-thumb rather than Manual J load calculation. The result: short cycling, uneven temperatures, and premature component failure. We correct this with proper load calculations before any replacement.

Palo Alto’s furnace repair pricing falls in the same $175–$825 range we see across the mid-Peninsula, though CPAU’s electrical requirements and local permit fees can add cost to full replacements. The city’s reach codes may require panel upgrades that neighboring Menlo Park or Mountain View don’t enforce. We factor all of this into your upfront quote.
We stand behind our labor with a written warranty, and any new equipment carries the manufacturer’s full warranty — typically 10 years on parts for major brands when registered properly.
