We’ve worked on Berkeley heating systems for 13 years, from the salt-air flatlands near the marina to the fire-rebuilt homes in the hills above Claremont Canyon. Gregory Hahn founded this company and still leads every technical decision, which means when you call Redwood Heating & Air, you’re getting master-technician diagnosis, not a dispatcher sending whoever’s available. Berkeley’s housing stock, microclimates, and evolving energy codes create heating challenges you won’t find in a generic manual. We know them because we’ve solved them.
Why Redwood Heating & Air San Diego Is Berkeley’s Preferred Heating & Furnace Company
Our reputation in Berkeley is built on 428 verified customer reviews averaging 4.6 stars, earned over 13 continuous years, not bought overnight. Homeowners in the Elmwood district and property managers near the UC campus call us back because we diagnose right the first time, whether it’s a failed ignitor in a 1990s Goodman or a cracked heat exchanger in a hills-area Trane.
Response time to Berkeley averages same-day or next-morning for non-emergency calls, and we prioritize emergency heating failures during cold snaps or Diablo wind events when the temperature drops fast in the hills. We service your brand, not just the one we sell, which matters in Berkeley where you’ll find nine major HVAC brands in regular use across the city’s mixed housing stock.
Gregory Hahn’s Master Technician designation means the company’s top credential is on the truck, not in a corporate office. From a single mini-split to a full commercial system, we bring the same technical rigor. That accountability is why Berkeley customers who’ve been burned by rushed repairs or one-brand-only dealers stick with us.
Our Heating & Furnace Services in Berkeley
Furnace Repair in Berkeley
Furnace repair in Berkeley costs $150–$700 depending on the component and accessibility. In the flatlands near San Pablo Park and the 94702 ZIP, we regularly see premature burner and heat exchanger fin failure from coastal salt-air corrosion, cutting equipment life to 5–7 years instead of the expected 15. Hills homes in 94705 and 94707 face different issues: ember-resistant vent screens installed after the 1991 Tunnel Fire clog with pine needles and debris, choking airflow and triggering limit-switch shutdowns. We clean or replace those screens to Berkeley Wildfire Safety code, not just generic manufacturer spec.
Furnace Replacement in Berkeley
A full furnace replacement in Berkeley runs $3,500–$7,500, but the real question for many homeowners is whether to replace at all. Berkeley was the first U.S. city to ban natural gas hookups in new construction in 2019, and despite a 2023 federal court reversal, its aggressive electrification culture drives far higher demand for heat-pump systems over gas furnaces than in neighboring Oakland or Richmond. We recently replaced a failing gas furnace in a flatlands craftsman bungalow near San Pablo Park (94702) with a ductless mini-split heat pump system, because the 1920s home had no existing ductwork and the homeowner wanted to align with Berkeley’s electrification push. We installed a Daikin ductless unit with hyper-heat capability to handle the cool bay air, and sealed the old furnace flue per current code. If you’re staying with gas, we size and install Bryant, Carrier, and American Standard furnaces with proper load calculations for Berkeley’s microclimates.
Furnace Tune-Up in Berkeley
A furnace tune-up in Berkeley costs $80–$200 and should happen annually, though flatlands homes near the bay may need semi-annual checks due to accelerated salt corrosion. Our tune-up covers burner inspection, heat exchanger integrity testing, gas pressure verification, and airflow measurement. In pre-war bungalows with gravity or floor furnaces, we check for uninsulated, undersized supply ducts that freeze or collapse, causing uneven heating and high energy bills. Catching these issues before December cold snaps saves Berkeley homeowners from emergency calls when every technician is booked solid.
Heat Exchanger Repair & Replacement in Berkeley
Heat exchanger failure is a safety-critical issue we treat with zero tolerance for delay. A cracked exchanger can leak carbon monoxide into living spaces, and in Berkeley’s tightly sealed vintage homes, that risk compounds. Repair costs vary by furnace age and brand, but replacement often makes more sense on units over 12 years old. We inspect with combustion analyzers and borescope cameras, not just visual checks. In hills homes with post-1991 rebuild furnaces, we verify that replacement units maintain fire-rated exterior penetrations and ember-resistant venting per Berkeley’s Wildfire Safety regulations.

Trusted Brands We Service in Berkeley
We service your brand, whether it’s a Carrier Infinity system in a North Berkeley hills home, a Trane XV in a commercial building near Shattuck Avenue, or a Bryant Legacy unit in a rental property off Telegraph. Gregory Hahn holds factory training or equivalent field experience across nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. We stock common parts for Berkeley’s most prevalent brands, which means faster turnaround and fewer return trips. For less common systems or older units in Berkeley’s pre-war housing stock, we source parts through our Bay Area supplier network, typically within 24 hours.
Common Heating & Furnace Problems We See in Berkeley Homes
- Coastal salt-air corrosion in flatland furnaces. Homes near the marina, along University Avenue, and in the 94710 ZIP see accelerated rust on heat exchanger fins, burner assemblies, and cabinet hardware. We replace corroded components with coated or stainless alternatives where possible, and recommend more frequent inspection intervals for these addresses.
- Ember-resistant vent screen clogging in hills homes. Properties in 94705, 94707, and 94708 rebuilt after the 1991 Tunnel Fire have specialized venting that traps debris. Reduced airflow causes furnaces to overheat and cycle on high-limit switches, often misdiagnosed as thermostat or control board failures by technicians unfamiliar with Berkeley’s fire-code layers.
- Undersized or collapsed ductwork in pre-war bungalows. The 1905–1940s craftsman homes concentrated in 94702 and 94703 were never built for forced-air systems. Gravity furnaces, floor furnaces, or later retrofit ducts are frequently uninsulated, poorly routed through crawl spaces, and prone to collapse or freeze. The result is uneven heating, high gas bills, and rooms that never reach set temperature.
- Microclimate mismatch between equipment and location. A furnace properly sized for a cool flatlands home near the bay will be undersized for a hills property exposed to Diablo winds. Conversely, oversized equipment in flatlands homes short-cycles, wasting fuel and degrading components. We perform Manual J load calculations for every replacement to match Berkeley’s extreme east-west temperature split.

What moves a repair toward the high end? Accessibility matters in Berkeley’s hillside homes with tight crawl spaces, and fire-code venting components cost more than standard hardware. For replacements, ductwork modifications in pre-war bungalows add labor, while straightforward swaps in post-1991 rebuild homes stay closer to the midpoint. We provide upfront, itemized quotes before any work begins. Estimates are free. Call (844) 875-9451 to schedule.

FAQs — Heating & Furnace in Berkeley
No, you are not legally required to convert an existing gas furnace to a heat pump, though Berkeley’s 2019 natural gas ban for new construction (later reversed in federal court) created strong cultural and financial incentives for electrification. Many Berkeley homeowners choose heat pumps for new installations or replacements to align with local policy direction, access rebates, and future-proof their homes. We install both high-efficiency gas furnaces and ducted or ductless heat pump systems, and we’ll recommend what fits your home’s infrastructure and your priorities. Call (844) 875-9451 for a free consultation.
Your furnace is likely overheating due to restricted airflow from clogged ember-resistant vent screens, a safety feature required on homes rebuilt after the 1991 Tunnel Fire. Diablo winds compound the problem by creating strong pressure differentials that draw debris against screens already partially blocked. We clean or replace these screens to Berkeley Wildfire Safety code and verify proper airflow with digital measurement. Call (844) 875-9451 before the next wind event to prevent mid-winter failure.
Yes, through ductless mini-split heat pumps or high-velocity small-duct systems designed for retrofit applications. Most Berkeley flatlands bungalows in 94702 and 94703 were built without central ductwork, making ductless the dominant installation approach rather than simple equipment swaps. We recently replaced a failing gas furnace in a flatlands craftsman bungalow near San Pablo Park (94702) with a Daikin ductless mini-split heat pump system with hyper-heat capability to handle the cool bay air, and sealed the old furnace flue per current code. Call (844) 875-9451 to assess your specific layout.
Once yearly at minimum, and every six months if your home is within a mile of the bay in 94702, 94703, or 94710. Coastal salt-air accelerates corrosion of heat exchanger fins and burner components, leading to premature failure within 5–7 years without proper maintenance. Our tune-ups include corrosion inspection and protective coating application where appropriate. Call (844) 875-9451 to schedule before the heating season.
Yes, homes in the hills fire zones (94705, 94707, 94708) rebuilt after 1991 must maintain ember-resistant vent screens, fire-rated exterior HVAC penetrations, and clearances that differ from standard installations. Replacing a furnace in these zones requires compliance with Berkeley’s Wildfire Safety regulations, not just manufacturer instructions. We handle permit verification and install to code. Call (844) 875-9451 for a replacement quote that includes all fire-code requirements.
