Why Redwood Heating & Air San Diego Is Palo Alto’s Preferred Heating & Furnace Company
We’ve built our reputation in Palo Alto one repair at a time. Gregory Hahn founded this company and still leads every technical decision, so when you call, you’re getting owner-level accountability, not a dispatcher reading from a script. Our 428 verified reviews average 4.6 stars across 13 years of continuous operation, and Palo Alto customers specifically mention our diagnostic thoroughness and the fact that we don’t push equipment swaps when a repair makes sense.
Response time to Palo Alto is typically under 90 minutes during business hours, and our trucks carry factory-authorized parts for Carrier, Trane, Bryant, and American Standard systems. That inventory matters in a city where many homes heat with original equipment from the 1970s and 1980s, and where a failed heat exchanger on a cold January night isn’t something you can wait on.
Our local knowledge runs deeper than zip codes. We know which Professorville crawlspaces have the clearance for a new 95% AFUE furnace and which Barron Park Eichlers will need a full slab-abandonment and mini-split conversion instead. That specificity saves Palo Alto homeowners from proposals that ignore their home’s actual constraints.
Our Heating & Furnace Services in Palo Alto
Furnace Repair
Palo Alto furnace repair runs $150–$700 depending on the component and accessibility. In Old Palo Alto and Professorville, we regularly service 30- to 50-year-old furnaces in pier-and-beam homes where the unit sits in a generous crawlspace. The repair is usually straightforward. In hillside homes above Page Mill Road, we sometimes find furnaces squeezed into converted closets with zero service clearance, which adds labor but doesn’t change our approach: diagnose first, quote second, repair only what’s necessary. We service your brand, whether it’s a Carrier, Trane, Bryant, or American Standard system.
Furnace Replacement
A full furnace replacement in Palo Alto typically falls between $3,500 and $7,500 installed, with high-efficiency modulating systems at the upper end. We size every replacement to the home’s actual heat loss, not the label on the old unit. In the 94304 foothills, where Diablo winds drive winter temperature swings, proper sizing matters more than in the flatlands near the Bay. We recently routed a new gas line and installed a high-efficiency Carrier furnace in a 1920s craftsman on Bryant Street in Professorville, where the pier-and-beam crawlspace gave us clean access for the duct retrofit, a far cry from the slab-to-mini-split conversions we do daily in Eichlers.
Furnace Tune-Up
Annual furnace tune-ups in Palo Alto cost $80–$200 and pay for themselves in efficiency gains and prevented breakdowns. We perform combustion analysis, inspect heat exchangers for cracks, and clean burners on every visit. For Eichler owners still running original slab-radiant boilers, our tune-up includes pressure testing and circulation pump inspection. Those systems are living on borrowed time, and we tell you honestly when repair costs exceed replacement value.
Heat Exchanger Inspection & Replacement
A cracked heat exchanger is a safety shutdown, period. In Palo Alto’s older housing stock, we find heat exchanger failures most often in furnaces past 20 years, especially in homes where filters were neglected and airflow was restricted. Replacement runs $800–$2,200 depending on furnace age and parts availability. For units where the heat exchanger is obsolete, we quote replacement honestly rather than chasing discontinued parts for three weeks. Carbon monoxide risk is real, and we don’t soft-pedal it.

Trusted Brands We Service in Palo Alto
We carry factory-authorized parts for Carrier, Trane, Bryant, and American Standard systems on every Palo Alto truck. That inventory, built over 13 years of multi-brand service, means same-day completion on most repairs instead of a return trip after parts are ordered. Gregory Hahn holds a Master Technician designation and has factory training or deep field experience across nine major HVAC brands, so when we say we service your brand, we mean we know its failure modes, not just how to read the manual.
Common Heating & Furnace Problems We See in Palo Alto Homes
- Copper radiant pipe leaks in Eichler slabs cause warm wet spots on floors and boilers that short-cycle endlessly. The pipes are 60+ years old and embedded in concrete. Once corrosion breaches the line, the system is unrepairable. We abandon the slab and spec a ductless mini-split conversion, the only practical path for homes with no attic and flat roofs.
- Flat-roof Eichlers have zero path for ductwork. We’ve had Palo Alto homeowners ask us to “just add ducts” to a Fairmeadow Eichler. There is no attic, no soffit chase, and the open beam ceiling is structural. Furnace retrofits are physically impossible. Mini-splits are the heating solution, and we’ve done enough of them to know the permit package the city expects.
- Hillside homes in 94304 face equipment access nightmares. Steep driveways off Old Page Mill Road and narrow setbacks above Arastradero mean a standard furnace replacement truck may not reach the pad. We plan crane or boom access in advance, not after showing up and discovering the problem.
- Pre-WWII furnaces in Professorville and Old Palo Alto often run past 40 years with band-aid repairs. At some point, parts obsolescence and efficiency penalties make replacement the rational choice. We give honest thresholds, not pressure.

FAQs — Heating & Furnace in Palo Alto
Yes, a warm wet spot on your Eichler slab almost always indicates a leaking copper radiant pipe inside the concrete. The pipe corrodes from the inside after 60+ years of water contact, and the leak pressurizes that section of slab. We confirm with thermal imaging and pressure testing, then discuss abandonment and mini-split conversion, since the pipe is not accessible for repair. Call (844) 875-9451 and we’ll assess whether the leak is localized or systemic.
No, a conventional furnace with ductwork cannot be installed in a standard Eichler. The flat roof eliminates attic space, the open beam ceiling has no chase capacity, and the slab foundation prevents below-floor ducts. We’ve evaluated this exact question dozens of times in Barron Park and Fairmeadow, and the physics don’t change. Ductless mini-splits are the heating and cooling solution for Eichlers, and we size them to the home’s actual load.
A furnace replacement in Palo Alto typically costs $3,500–$7,500 installed, with single-stage 80% AFUE units at the lower end and modulating 96% AFUE systems with advanced filtration at the upper end. Hillside homes in 94304 with access challenges may incur additional equipment costs. Call (844) 875-9451 for a free in-home estimate with exact sizing and options.
No, the mechanical permit requirements are citywide, but the documentation package differs by project type. Eichler mini-split conversions require electrical load calculations and line-set routing diagrams that standard furnace replacements don’t. The permit desk at 285 Hamilton Ave knows this workflow well, and experienced contractors bring the complete package on first submission. We handle permits as part of our installation service.
Most 94304 hillside properties require advance planning for equipment access. Steep driveways and narrow setbacks off Old Page Mill Road and Arastradero may need crane, boom, or manual rigging. We survey access during our free estimate visit and build the logistics into our proposal, not as a surprise add-on. Call (844) 875-9451 to schedule a site assessment.
