Alamo’s not like other Bay Area towns. Behind the coastal hills, you’ve got genuine inland heat in summer, cold Delta breeze nights in winter, and some of the most expensive custom homes in Contra Costa County. Your furnace probably lives in an attic that hits 150°F in July. That specific combination — extreme attic temperatures, large square footage, and multi-zone duct systems — is exactly what we’ve spent nearly two decades learning to handle.

Why Crestview Heating & Air California Is Alamo’s Preferred Heating & Furnace Company

We’ve built a 4.8-star average across 250+ customer reviews, and a growing chunk of those come from Alamo homeowners who found us after frustrating experiences with dispatch-heavy companies that sent technicians who’d never seen a 5,000 sq ft hillside estate. Owner Marcus Feldman still serves as our Service Manager, which means when you call Crestview, you’re getting ownership-level accountability on every job — not a rotating cast of subcontractors.

Our familiarity with Alamo’s specific housing stock matters. Homes on Country Club Drive, Royal Oak, and Calle Verde — mostly built between the late 1960s and early 1990s — have furnace placements and duct configurations that differ significantly from standard tract construction. We’ve replaced heat exchangers in attics off Danville Boulevard, resealed leaky duct runs in pre-1990s homes near the golf course, and matched modulating furnaces to smart-home systems in newer custom builds. That local pattern recognition saves you diagnostic time and money.

We don’t charge extra for the Alamo drive. Our pricing matches what we quote in San Jose, and we carry parts for Trane, Lennox, Goodman, and Rheem on our trucks to minimize return trips.

Our Heating & Furnace Services in Alamo

Furnace Repair

A typical furnace repair in Alamo runs $150–$700. The most common calls we get from Alamo homes involve ignitor failures and gas valve malfunctions — both accelerated by the extreme thermal stress of 150°F+ attic summers followed by 40°F winter nights. In hillside estates on Country Club Drive, we’ve seen ignitors fail in as little as 3–4 years because of that cycling. We diagnose the root cause, not just the symptom, so you’re not replacing the same part twice.

Furnace Replacement

Full furnace replacement in Alamo typically costs $3,500–$7,500. Most Alamo homes need more than a straight swap. Original ductwork in 1970s and 1980s builds was sized for the equipment of that era, not for modern high-efficiency furnaces with higher static pressure requirements. We evaluate whether your ducts can support a 96% AFUE modulating unit or if you’ll need a retrofit — and we tell you upfront, not after we’ve ripped out your old system.

Furnace Tune-Up

Our furnace tune-ups run $80–$200. For Alamo’s large custom homes, this isn’t a quick filter swap. We check heat exchanger integrity with a borescope, test gas pressure at the manifold, measure temperature rise across the coil, and inspect duct seams for leakage — especially critical in homes with long attic runs where 30%+ of heated air can escape before reaching your living space. Annual tune-ups catch the thermal-cycling damage that’s endemic to Alamo’s climate before it becomes a mid-winter failure.

Heat Exchanger Inspection & Replacement

Heat exchanger failure is more common in Alamo than in nearby Danville, and it’s not random. The extreme delta between cold Delta breeze nights and superheated attic days creates thermal expansion stress that cracks steel exchangers over time. We’ve replaced cracked exchangers in Lennox, Carrier, and Goodman units throughout Alamo’s older estates. This is safety-critical work — a cracked exchanger can leak carbon monoxide into your duct system. We always recommend professional inspection; this is not a homeowner diagnosis.

Gas Valve Repair

Gas valve failures spike in Alamo attics during and after summer heat waves. The valve’s solenoid and diaphragm materials degrade faster when ambient temperatures routinely exceed 150°F. We’ve replaced gas valves on Royal Oak and Danville Boulevard homes where the valve simply wouldn’t open reliably after three consecutive 100°F+ days. If your furnace is clicking but not firing, especially after a hot week, call us before it fails completely.

Ignitor Replacement

Hot-surface ignitors in Alamo furnaces typically last 4–6 years, shorter than the national average, due to attic thermal cycling. We stock ignitors for all nine major brands we service, including the less common Daikin and York parts that many competitors have to order. Same-day replacement is standard when you call before noon.

Trusted Brands We Service in Alamo

We service nine major HVAC brands — Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard — and we stock the most common repair parts for Trane, Lennox, Goodman, and Rheem on our Alamo-bound trucks. That inventory matters when your furnace fails on a Friday evening and the part would otherwise ship from a warehouse in Sacramento. We’ve completed same-day Lennox heat exchanger replacements and Goodman gas valve swaps because we didn’t have to wait for delivery. For custom Alamo homes with smart-home integration, we have particular experience matching Daikin and Trane modulating furnaces to home automation systems — not every technician understands how a variable-speed blower interfaces with a Crestron or Control4 setup.

Common Heating & Furnace Problems We See in Alamo Homes

• Heat exchanger cracks from extreme thermal cycling. In Alamo’s hillside estates, especially on Country Club Drive, furnaces endure 40°F nights and 150°F attic days. That 110°F daily swing fatigues steel heat exchangers over 10–15 years, producing cracks that leak combustion gases into conditioned air. We catch these with borescope inspection during tune-ups.
• Gas valve and ignitor failures accelerated by attic heat. Homes on Royal Oak and Danville Boulevard see premature ignition component failure because summer attic temperatures exceed the design specs of standard residential parts. We upgrade to high-temp-rated components where appropriate.
• Multi-zone duct leakage wasting 30%+ of heated air. Pre-1990s homes on Calle Verde and nearby streets often have original ductwork with unsealed joints and inadequate insulation. Before we replace any furnace, we measure duct leakage with a blower door and duct blaster — replacing an efficient furnace connected to leaky ducts is throwing money away.
• Undersized furnaces struggling with Alamo’s true heat load. Many Alamo homes were built with furnaces sized for “Bay Area mild” conditions, not for the genuine inland cold that settles into the San Ramon Valley on clear winter nights. A furnace that cycles constantly or can’t hold temperature on a 35°F morning is probably undersized for your actual square footage and infiltration rate.
