Why Redwood Heating & Air San Diego Is Winters’s Preferred Heating & Furnace Company
Gregory Hahn founded this company and still leads every technical decision. That matters in Winters, where a furnace sized for Woodland or Davis will short-cycle itself to death. Our 428 verified reviews averaging 4.6 stars reflect 13 years of homeowners who got correctly diagnosed problems, not convenient upsells.
We respond to Winters calls from our Davis-area dispatch, typically arriving same-day for emergencies and within 24 hours for standard bookings. That includes the older homes near downtown with original floor plans and minimal ductwork, the 1990s subdivisions off Wolfskill Road, and the newer construction around West Main Street where builder-grade systems are already showing their limitations.
Our Master Technician credential is on the truck, not in a corporate office. When you call Redwood Heating & Air, you’re getting owner-level accountability. We’ve spent 13 years learning which furnace models survive the Gap’s wind-driven temperature swings and which ones don’t.
Our Heating & Furnace Services in Winters
Furnace Repair in Winters
Most furnace repairs in Winters fall between $150–$700, depending on whether we’re replacing a failed ignitor, cleaning a flame sensor coated in agricultural dust, or tracking down a control board issue. The Berryessa Gap’s rapid evening cool-downs stress ignition systems particularly hard: a furnace that fired three times in a Davis evening might cycle eight times in Winters, wearing out ignitors and gas valves faster than the manufacturer’s specifications assume. We carry common parts for Trane, Lennox, Goodman, and Rheem units on our trucks, and we stock additional filters sized for the heavy dust load Winters sees during almond and walnut harvest.
Furnace Replacement in Winters
Replacing a furnace in Winters demands more than swapping like-for-like. The town’s unique thermal profile — 100°F summer afternoons followed by 70°F evenings thanks to the Gap’s marine air surge — means single-stage, single-speed furnaces are almost always the wrong choice here. We replaced a builder-grade 80% AFUE furnace in a 2021 home on West Main Street with a two-stage Lennox (model SLP98V) sized correctly for the Gap’s evening cool-down. The homeowner’s old unit short-cycled on mild evenings; now it runs steady, cuts gas use, and handles the sudden 30°F drops. Whether you’re in a 1940s cottage near Abbey Street with no existing ductwork or a 2005 tract home off East Baker Street with a failed original unit, we’ll size the replacement using Manual J calculations that account for Winters’s actual conditions, not Sacramento Valley defaults.
Furnace Tune-Up in Winters
A furnace tune-up in Winters runs $80–$200 and should happen every fall, ideally before the walnut chaff starts flying in September. Our tune-up includes combustion analysis, heat exchanger inspection, gas pressure verification, and a filter assessment. Given Winters’s colder winter nights from cold-air drainage off the Vaca Mountains, a poorly tuned furnace works harder here than in Davis, burning more gas for the same thermostat setting. We also check outdoor vent terminations — the Gap’s persistent winds can dislodge PVC venting on high-efficiency units, creating dangerous backdraft conditions. For homes near the agricultural processing facilities along Putah Creek Road, we pay extra attention to coil and blower cleanliness.
Heat Exchanger Inspection and Replacement in Winters
Heat exchanger failures in Winters typically cost $150–$700 to address, though a cracked exchanger often means replacement is the safer long-term option. The stress is real here: oversized furnaces that short-cycle through rapid evening temperature swings develop thermal fatigue cracks faster than properly sized equipment. In the older homes near downtown Winters, we’ve found original heat exchangers still running after 40 years in properly maintained units, while poorly sized replacements in newer homes have failed in under eight. We use combustion analyzers and borescope cameras to verify exchanger integrity, and we’ll show you the footage. If replacement makes more sense than repair, we’ll explain why without pressure.
Ignitor Replacement and Gas Valve Repair
Hot surface ignitors in Winters fail more frequently than manufacturer specs suggest, thanks to the extra cycling demanded by the Gap’s temperature volatility. A standard ignitor replacement runs toward the lower end of our repair range, while gas valve work sits higher due to parts cost and the safety-critical nature of the repair. We don’t recommend DIY on either: gas valve misassembly creates leak risks, and ignitor handling without proper static protection destroys the new part before it fires once.

Trusted Brands We Service in Winters
We service your brand, whether it’s a Trane XV80 in a 2015 subdivision, a Lennox SLP98V we installed on West Main Street, a Goodman GMVC96 in a rental near Railroad Avenue, or a Rheem Classic Plus in a commercial space off Grant Avenue. Our technicians carry factory training or equivalent field experience across nine major HVAC brands, so we diagnose based on symptoms and engineering, not a single manufacturer’s flowchart. For Winters customers, that means faster repairs with fewer return trips, and honest guidance when replacement makes more sense than chasing intermittent failures in an aging unit.
Common Heating & Furnace Problems We See in Winters Homes
- Oversized furnaces short-cycling through rapid evening drops. The Berryessa Gap’s 20–30°F evening cool-down triggers constant on-off cycling in builder-grade single-stage units, wasting fuel and wearing out heat exchangers prematurely. We see this most in 2000s-era tract homes where the original contractor sized for static valley heat loads.
- Builder-grade single-stage units struggling with overnight swings. Bedrooms chill by morning as the furnace blasts full output then shuts off completely, creating temperature stratification. Two-stage or modulating equipment solves this, but most Winters new construction didn’t include it.
- Harvest dust clogging filters within weeks. Almond and walnut chaff from September through November loads standard 1-inch fiberglass filters faster than the 90-day replacement schedule most homeowners follow. We recommend mid-season swaps and higher-MERV pleated options for homes near processing facilities.
- Wind-damaged vent terminations on high-efficiency units. The Gap’s persistent winds dislodge or crack PVC venting on 90%+ AFUE furnaces, creating potential carbon monoxide backdraft. Our fall tune-ups include vent integrity checks as standard.

FAQs — Heating & Furnace in Winters
Your furnace is likely short-cycling through the Gap’s rapid evening temperature drops, burning fuel inefficiently without delivering steady comfort. Single-stage units fire at full output, overshoot the thermostat, shut off, then repeat minutes later as the wind-driven cool-down resumes. A two-stage or properly sized system runs longer at lower output, using less gas overall. Call (844) 875-9451 for a combustion analysis and sizing review — estimates are free.
No. That’s classic short-cycling from an oversized unit ignoring the Berryessa Gap’s evening cool-down effect. Builder-grade contractors often use Sacramento Valley Manual J defaults that don’t account for Winters’s 20–30°F rapid drops. The constant cycling wears out ignitors, heat exchangers, and blower motors prematurely while spiking your gas bill. We can verify sizing and recommend correction options, from equipment replacement to control modifications.
Every 3–4 weeks from September through November, and every 6–8 weeks the rest of the year. The almond, walnut, and wine-grape operations surrounding Winters shed dust and chaff that loads filters far faster than typical suburban conditions. A clogged filter restricts airflow, causing the heat exchanger to overheat and the limit switch to trip — or worse, crack the exchanger from excessive cycling. We stock common filter sizes for Winters customers and can set up seasonal reminder calls.
Yes, with caveats. Modern cold-climate heat pumps perform to single-digit temperatures, but Winters’s winter nights run colder than Davis due to cold-air drainage from the Vaca foothills. A dual-fuel system — heat pump for mild conditions, gas furnace below 35°F — often makes the most economic sense here, leveraging the Gap’s moderate temperatures for much of the heating season while ensuring reliable output on the coldest nights. We’ll run load calculations specific to your home’s location and insulation level.
The Gap’s temperature volatility forces more ignition cycles than the manufacturer designed for. A furnace in steady-cold climates might fire 3–4 times nightly; in Winters, the rapid evening drop and overnight recovery can demand 8–10 cycles. Each cycle thermally stresses the silicon carbide or nitride ignitor. Upgrading to a two-stage furnace reduces cycle count, and we can install extended-life ignitors where compatible. Annual tune-ups catch weakening ignitors before they fail completely.
