Concord sits inland past the coastal hills in the Diablo Valley, placing it in a completely different thermal world than the rest of the Bay Area. Summer heat waves routinely push 100–105°F while San Francisco sits at 65°F fog on the same afternoon. Because Bay Area homes were historically built assuming coastal temperatures, a large share of Concord’s 1960s–1970s housing stock was constructed with heating only and no provision for central air, making furnace work here fundamentally different from coastal cities. Our Heating & Furnace team sees this every winter: a furnace that was “fine” for decades suddenly can’t keep up because the ductwork was never designed for the cooling loads homeowners now demand.
Why Redwood Heating & Air San Diego Is Concord’s Preferred Heating & Furnace Company
Gregory Hahn founded this company and still leads every technical decision. After 13 years in business and 428+ verified reviews averaging 4.6 stars, we’ve earned a reputation in Concord for diagnosing right the first time — not sending a salesperson to quote a replacement when a $200 gas valve would fix the problem.
Our response time to Concord neighborhoods — from the Monument Corridor to Dana Estates to the ranch homes off Treat Boulevard — is typically same-day or next-morning for non-emergencies, and we prioritize emergency calls when temperatures drop into the 30s and a failed furnace threatens pipes or health. We service your brand, whether it’s a 15-year-old Goodman in a Clayton Valley tract home or a high-efficiency American Standard in a newer development near the Veranda.
What separates us from one-brand dealers and franchise dispatchers is simple: Gregory Hahn holds a Master Technician designation, and that expertise is on your job, not locked in a corporate office. We’ve spent 13 years learning how Concord’s specific conditions — the Diablo Valley’s 35–45°F daily temperature swings, the original 100-amp panels, the collapsed flex duct in crawl spaces — create failure modes that coastal HVAC techs rarely encounter.
Our Heating & Furnace Services in Concord
Furnace Repair
Furnace repair in Concord runs $150–$700 for most common failures: bad ignitors, failed gas valves, cracked heat exchangers, and blower motors stressed by undersized ductwork. We see a lot of the last one in 94520 and 94521 zip codes, where 1970s ranch homes have flex duct that’s partially collapsed or never insulated. The blower works harder, draws more amps, and dies young. We fix the immediate failure and flag the underlying cause so you’re not calling us again in March.
Furnace Replacement
Furnace replacement in Concord is where our local experience pays off most. Concord’s 1960s–1970s ranch homes often have only heating ducts sized for heating airflow, so a furnace replacement here — unlike in coastal cities — frequently requires ductwork resizing and MERV-rated filter upgrades to handle cooling loads as well. Last July we replaced a 1972 Lennox furnace in a ranch home on Meadow Lane in the Monument Corridor. The original 100-amp panel could not handle a condenser, so we coordinated a panel upgrade with a licensed electrician, installed a new Carrier 80% furnace on the crawl space, and rerouted flex duct that had collapsed. The homeowner got a system that finally kept the bedrooms cool during 105°F afternoons. Replacement cost: $3,500–$7,500 depending on whether you’re looking at a straight swap or the full cascade.
Furnace Tune-Up
A furnace tune-up in Concord costs $80–$200 and should happen every fall before the first cold snap. We check gas pressure, flame sensor operation, heat exchanger integrity, and blower amp draw. In Concord specifically, we also inspect crawl-space duct condition and static pressure — the combination of winter heating demand and summer AC retrofits on original ductwork creates unique wear patterns here. Catching a failing blower capacitor in October beats an emergency call at 11 PM on a 38°F night in December.
Heat Exchanger Inspection & Replacement
Cracked heat exchangers are a safety issue we take seriously. In Concord’s older housing stock, especially floor furnaces and early forced-air systems near downtown and the Monument Corridor, rust and age create failure risks that carbon monoxide detectors might not catch in time. We inspect with visual scopes and combustion analyzers. If replacement is needed, we’ll explain exactly why and show you the crack — no vague scare tactics, just the facts and your options.

Trusted Brands We Service in Concord
We service your brand — Carrier, Trane, Lennox, Bryant, American Standard, and four others — because Gregory Hahn built this company on master-technician-level diagnosis, not single-brand convenience. For Concord customers, that means faster repairs: we stock common ignitors, gas valves, and blower motors for the brands most prevalent in 94518, 94519, 94520, and 94521, and we know the failure patterns specific to each. A Bryant Plus 80 in a 1990s Concord ranch has different common faults than a Carrier Infinity in a newer build near the Veranda. That fluency saves you a return visit.
Common Heating & Furnace Problems We See in Concord Homes
- Original floor furnaces near the Monument Corridor are often rusted out with unsafe gas leaks. These units, common in pre-1960s pockets of Concord, have exceeded their design life by decades. We don’t patch them — we replace with modern forced-air systems that meet current codes and don’t risk carbon monoxide infiltration through corroded heat exchangers.
- Undersized 100-amp panels in 1960s tract homes can’t support a furnace blower and condenser simultaneously. When homeowners add AC to a heating-only system, the combined load trips breakers and causes voltage drops during peak heat. We coordinate with licensed electricians for panel upgrades when needed, so your new system actually works when you need it.
- Uninsulated or collapsed flex duct in crawl spaces causes up to 30% heat loss in winter. Concord’s shallow crawl spaces and summer attic temperatures over 150°F degrade ductwork faster than in milder climates. The resulting static pressure overloads blower motors and creates cold spots in bedrooms. We measure static pressure on every service call and show you the numbers.
- Ignitor failures spike when furnaces first fire in fall. The thermal shock of sitting idle through Concord’s dry summer heat, then cycling on when nights drop to 40°F, cracks silicon carbide ignitors. We stock replacements for Carrier, Trane, Bryant, and American Standard systems and can usually swap same-day.

FAQs — Heating & Furnace in Concord
Concord’s 1960s–1970s ranch homes frequently need ductwork resizing, electrical panel upgrades, and crawl-space duct replacement alongside the furnace itself, while Walnut Creek’s newer housing stock more often allows a straight swap. The Diablo Valley’s temperature extremes also demand higher-capacity equipment. Call (844) 875-9451 for an exact quote on your specific home — estimates are free.
No — original floor furnaces in Concord’s older neighborhoods are typically past safe service life, with rusted heat exchangers that can leak carbon monoxide directly into living spaces. We replace them with modern forced-air systems that meet current safety codes. If you’re in a pre-1960s home near downtown or the Monument Corridor, we’ll inspect and give you a replacement plan with exact costs.
Once yearly, ideally in September or October before the first cold nights. Concord’s wide temperature swings and dry summer dust create unique wear on blower motors and flame sensors. A fall tune-up catches problems before you’re calling at midnight when it’s 35°F outside. Call (844) 875-9451 to schedule — we book fast as weather turns.
A 1,200–1,600 square foot 1960s Concord ranch typically needs 40,000–60,000 BTU, but the exact size requires a Manual J load calculation that accounts for your home’s insulation, window condition, and ductwork capacity. Many original furnaces here were oversized for heating-only loads and undersized for modern cooling expectations. We measure and calculate — no rule-of-thumb guesses that waste fuel or leave you cold.
Yes — ignitor replacement is one of our most common same-day repairs in Concord, especially in fall when systems first cycle after summer dormancy. We stock ignitors for Carrier, Trane, Bryant, American Standard, and other major brands. Most ignitor replacements run $150–$400 depending on accessibility and whether the failed ignitor damaged the control board. Call (844) 875-9451 — we’ll confirm your brand and part availability before we head out.
