Why Redwood Heating & Air San Diego Is Exeter’s Preferred Heating & Furnace Company

Gregory Hahn founded this company and still leads every technical decision. That means when you call about a failing furnace in Exeter, you’re getting a Master Technician’s judgment, not a dispatcher reading from a script. Our 428 verified customer reviews average 4.6 stars, built over 13 continuous years of operation — a track record that outlasts most local HVAC startups and one-truck operations.

We respond to Exeter calls with the urgency that valley winters demand. When tule fog settles in and your heat pump’s outdoor coil ices over at 6 a.m., you need someone who understands that “tomorrow” isn’t an option. Our trucks carry factory-authorized parts for nine major brands, so we’re not ordering components from Fresno while your family layers blankets. From a single mini-split to a full commercial system, we diagnose right the first time.

Exeter’s housing stock is personal to us. We’ve worked in the cramped crawlspaces beneath 1920s citrus-worker bungalows and retrofitted ductwork into 1960s ranch homes that were never designed for central air. That local fluency saves you money. We spot the cracked heat exchanger before it becomes a carbon monoxide risk, and we know when a heat pump is simply undersized for Exeter’s sharp diurnal swings rather than “broken.”

Our Heating & Furnace Services in Exeter

Furnace Repair

A furnace repair in Exeter runs $175–$825 depending on the component and accessibility. The most common call we get: a 1950s floor furnace or early central unit that won’t stay lit during the first dense fog of December. In Exeter’s older homes near Lincoln Park and along North F Street, we regularly find limit switches tripped from restricted airflow — citrus dust and agricultural smoke have choked the filter, or a squirrel-cage blower is caked with debris from decades of valley harvest seasons. We carry ignitors, gas valves, blower motors, and control boards for Lennox, Rheem, Goodman, and Carrier units on every truck.

Furnace Replacement

When a heat exchanger is cracked or a floor furnace has reached the end of its safe service life, replacement becomes the only responsible option. In Exeter, this often means more than swapping boxes. The original 1950s floor furnace in your bungalow wasn’t ducted. The 1970s add-on central system may have been sized for summer cooling alone, leaving it helpless during weeks of 40°F tule fog. We calculate heat load properly for Exeter’s specific conditions, not just square footage. A typical furnace replacement in Exeter ranges from $3,500–$7,500 depending on whether we’re adding ductwork, upsizing for winter demand, or sealing a leaky attic distribution system. We recently replaced a failing 3-ton heat pump on a 1940s bungalow on North F Street, where the original ductwork was routed through a crawlspace with clearances under 18 inches. The homeowner had been layering space heaters during winter fog, so we upsized to a 3.5-ton Carrier system with a 4-inch media filter cabinet and sealed the leaky attic ducts to block citrus dust and fog moisture.

Furnace Tune-Up

An annual furnace tune-up in Exeter costs $95–$235 and pays for itself in prevented failures. We perform these with specific attention to valley conditions: checking heat exchanger integrity after months of rapid expansion and contraction from 25°F daily temperature swings; measuring gas pressure and burner flame stability; inspecting blower wheels for citrus-dust buildup; and testing safety controls that get more workout here than in coastal climates. For homes near active groves or along Highway 65 where harvest traffic kicks up debris, we often recommend stepping up to 4-inch media filters and more frequent changes. A tune-up in October, before the first tule fog, catches the problems that become emergency calls at 5 a.m. in January.

Heat Exchanger Inspection & Replacement

This is the safety-critical service no Exeter homeowner should skip. A cracked heat exchanger can leak carbon monoxide into your living space, and in Exeter’s compact 1920s–1960s homes with limited ventilation, that risk is acute. Older floor furnaces develop cracks from decades of thermal cycling — hot metal expanding in the afternoon, contracting fast when Sierra downslope winds drop temperatures 20–25°F by evening. We inspect with visual borescopes, combustion analyzers, and smoke tests. If replacement is needed, we handle the full job including permit coordination. Heat exchanger work in Exeter typically falls in the upper half of our $175–$825 repair range, or triggers a full furnace replacement if the unit is past 15 years. We don’t patch heat exchangers. Ever.

Trusted Brands We Service in Exeter

We service your brand. Gregory Hahn holds factory training or equivalent field certification across Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard — nine major lines that cover virtually every system installed in Exeter homes over the past four decades. We stock common ignitors, gas valves, blower motors, and control boards for Lennox, Rheem, and Goodman locally, which means most Exeter repairs don’t wait on a Fresno parts run. For Carrier and Trane systems common in newer construction near the eastern edge of town, we maintain direct supplier relationships for next-day delivery on larger components. Brand-agnostic diagnosis matters in a town where one contractor may have installed whatever was cheapest in 1987, and another homeowner upgraded to a high-efficiency Rheem in 2019. We don’t guess. We identify, we test, we fix.

Common Heating & Furnace Problems We See in Exeter Homes

• Cracked heat exchangers in 1950s floor furnaces. The rapid expansion and contraction from Exeter’s sharp 25°F daily swings fatigues metal that’s already seen 60–70 years of use. We catch these with combustion analysis during tune-ups before they become CO hazards.
• Heat pumps frozen solid during tule fog. Systems sized for summer cooling alone can’t maintain output when weeks of dense fog keep temperatures near 40°F. The outdoor coil ices, defrost cycles fail, and homeowners wake to 52°F indoor temperatures. We evaluate whether supplemental heat, proper sizing, or a gas furnace conversion is the right fix.
• Citrus dust and agricultural smoke choking 1-inch filters. In Exeter’s air quality environment, a standard filter can clog within weeks during harvest season. Restricted airflow overworks the heat exchanger, leading to premature failure. We routinely upsize to 4-inch media cabinets and seal attic ducts on the same call.
• Leaky attic ductwork in homes never designed for central heat. Many Exeter bungalows had ductwork retrofitted into cramped attics with no proper chases. Heated air escapes into unconditioned space, or worse, pulls in dusty attic air through return leaks. Our blower-door testing finds what visual inspection misses.
