Why Redwood Heating & Air San Diego Is Irvine’s Preferred Heating & Furnace Company
Gregory Hahn founded this company and still leads every technical decision. That matters in Irvine, where furnace problems hide in identical floor plans and HOA-mandated installation constraints that generic crews miss.
Our 428 verified reviews averaging 4.6 stars include homeowners from Turtle Rock, Northwood, and University Park who specifically note that we spotted cracked heat exchangers and return-air deficiencies others walked past. Thirteen years in business means we’ve watched Irvine’s first-wave villages age into predictable failure cycles, and our Master Technician designation ensures the diagnosis comes from the owner, not a rotating subcontractor.
We’re certified to service nine major brands — Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard — so we repair what you have instead of pushing a single product line. From a single mini-split to a full commercial system, we service your brand.
Our Heating & Furnace Services in Irvine
Furnace Repair
Furnace repair in Irvine runs $150–$700 depending on the component and accessibility. We see the most calls from Woodbridge and Turtle Rock when original 1980s units fail during the first Santa Ana wind event of autumn — that sudden 100°F+ spike tricks homeowners into shutting off maintenance budgets, then the overnight temperature crash exposes weak ignitors and cracked exchangers. Our crew carries ignitors, gas valves, and high-limit switches for Carrier, Lennox, and Rheem units on every truck, so most Irvine repairs finish in one visit.

Furnace Replacement
Full furnace replacement in Irvine costs $3,500–$7,500, with older village homes often requiring duct modification that newer neighborhoods don’t. The identical floor plans in Woodbridge mean we’ve replaced the same furnace model in the same closet location dozens of times — we know exactly which return plenum upgrades fit, which line-set extensions the Irvine Company HOAs will approve, and how to route venting around those strict aesthetic screening rules. We replaced a 40-year-old Lennox furnace in a Turtle Rock home where the original duct system had never been sealed, sending heated air into the attic instead of the bedrooms. Our tech installed a high-efficiency Carrier with a proper return plenum, cutting the homeowner’s gas bill by 30%.

Furnace Tune-Up
A furnace tune-up in Irvine runs $80–$200 and pays for itself fast in this climate. The wide diurnal swings here — mid-90s days, marine-layer-cooled nights — cycle your system hard. In older villages, we focus on heat exchanger inspection and combustion analysis; in Great Park Neighborhoods, we verify HERS compliance and check for airflow restrictions from those HOA-mandated side-yard screens. Either way, we catch the cracks and carbon monoxide risks before they become emergencies.

Heat Exchanger Inspection & Replacement
Heat exchanger work is our most critical Irvine service. The identical floor plans in older villages like Woodbridge mean the same furnace placement and duct issues repeat house after house, creating a predictable pattern of heat exchanger cracks and undersized returns that our crew recognizes before we even open the attic hatch. Original attic ductwork splits at taped joints during Santa Ana wind pressurization, causing carbon monoxide backdrafts that kill silently. We test every exchanger with a combustion analyzer, document the results, and if replacement makes more sense than repair, we quote honestly.

Gas Valve Repair
Gas valve repair in Irvine typically falls in the $150–$400 range of our furnace repair pricing. We see failed valves most often in 1980s Lennox and Carrier units where years of cycling have worn the solenoid. Because we stock OEM and compatible valves for all nine brands we service, Irvine customers aren’t waiting a week for a part that we should have had on the truck.

Trusted Brands We Service in Irvine
We service Carrier, Trane, Lennox, Goodman, and Rheem equipment in Irvine homes daily, and we stock common repair parts for these brands on every truck. That matters when your furnace quits on a Sunday night in December and the Santa Ana winds are dropping temperatures fast. Our multi-brand fluency means we don’t guess — we diagnose, pull the right part, and restore heat. For full replacements, we source equipment through authorized distributors with full factory warranty registration, not gray-market units that leave you unprotected.
Common Heating & Furnace Problems We See in Irvine Homes
- Heat exchanger cracks from airflow starvation. The identical floor plans in Woodbridge funnel every home through the same undersized return air path. Restricted airflow overheats the exchanger, metal fatigues, and cracks form — often undetected until our combustion analyzer finds CO in the flue gases.
- Attic ductwork separation during Santa Ana events. Original 1970s–80s flex duct, taped at joints, pressurizes and splits when hot, dry winds pound the roof. Heated air dumps into the attic, the furnace runs endlessly, and homeowners wake up cold despite a roaring utility bill.
- High-limit switch trips from condenser airflow restriction. Irvine Company HOAs force condensers into tight, screened side yards that starve the outdoor unit. In winter, the restricted airflow backs into the furnace cabinet, tripping limits on days that shouldn’t stress the system at all.
- Failed ignitors from hard cycling. Those 15–20°F daily temperature swings in Irvine mean your furnace starts, stops, starts again. Silicon nitride ignitors last longer than older carbide styles, but neither survives indefinite cycling without inspection.

What moves you within these ranges? Accessibility matters — a furnace buried in an Irvine Company attic with 18 inches of clearance takes longer than a closet install. Duct condition matters — original unsealed attic systems add $800–$2,000 to replacement quotes when we fix what should have been done decades ago. And code compliance matters — Great Park Neighborhoods jobs require HERS verification and Title 24 documentation that older villages don’t. We price upfront, itemize everything, and never start work without your written approval. Call (844) 875-9451 for a free estimate.

FAQs — Heating & Furnace in Irvine
The identical floor plans in Woodbridge, Turtle Rock, and University Park used the same undersized return-air pathways, starving furnaces of adequate airflow and overheating the exchanger metal until it fatigued. We’ve found this pattern so consistently that our crew checks return static pressure before removing any panel. Call (844) 875-9451 if your home is in one of these villages and your furnace is original — we’ll inspect the exchanger for free with any service call.
Yes, if the heat exchanger passes our combustion test and the furnace is under 20 years old, gas valve replacement alone is often the right fix. In Irvine, we see this most on 1990s–2000s Carrier and Lennox units where the valve solenoid has simply worn out. We stock replacement valves for all major brands and can typically complete this repair same-day. Call (844) 875-9451 to schedule — estimates are free.
Most Irvine Company village HOAs require architectural review for any visible exterior modification, including venting changes or condenser relocation, but the mechanical permit itself is pulled through the city of Irvine or Orange County depending on your zip code. We handle both HOA documentation and city permitting as part of our replacement service, so you’re not navigating 92606 or 92614 bureaucracy alone. Call (844) 875-9451 and we’ll verify your specific HOA’s requirements before quoting.
Sudden pressurization from Santa Ana winds commonly splits original attic ductwork at taped joints, causing the furnace to short-cycle or the high-limit switch to trip as heated air escapes into the attic rather than reaching your rooms. We see this emergency call spike every October and November in Woodbridge and Turtle Rock. If your furnace blows cold after a wind event, shut it off and call (844) 875-9451 — we’ll prioritize same-day response for suspected duct separation.
For homes in 92612, 92614, and 92616 with original 80% furnaces, a 96% condensing unit typically pays back in 6–10 years through gas savings alone, faster if we pair it with sealed ductwork. The mild but variable Irvine winter means your furnace runs enough to matter, but not so constantly that efficiency gains are negligible. In our Turtle Rock case study, the homeowner saw a 30% gas bill drop. Call (844) 875-9451 and we’ll model payback for your specific home and usage.
