Fast, Reliable Heating & Furnace Across Aptos
Heating and furnace repair in Aptos typically runs $150–$700 for most repairs, with furnace tune-ups at $80–$200, and our Heating & Furnace team can usually diagnose your system same-day. If you’re in the 95001 or 95003 zip codes, we’re familiar with your neighborhood’s specific challenges — from the salt-air corrosion that eats coastal equipment to the legacy wall furnaces in mid-century cottages that no longer have replacement parts available.
We’ve been driving to Aptos from our San Jose base for years, and we know the difference between a quick fix on a newer system in the Seacliff area and a full replacement job on a 1960s gravity furnace in Rio del Mar. Marcus Feldman, our owner and Service Manager, still manages calls personally. That means when you reach Crestview Heating & Air California at (844) 560-6978, you’re talking to someone with 19 years of field experience who can tell you honestly whether your system is worth saving. Nearly two decades of HVAC experience means we’ve seen virtually every furnace configuration Aptos throws at us.
Why Crestview Heating & Air California Is Aptos’s Preferred Heating & Furnace Company
Our 4.8-star average across 250+ customer reviews didn’t come from easy jobs. It came from showing up when Aptos homeowners needed us — including emergency calls during January cold snaps when that marine layer turns from foggy to genuinely chilly. 250+ customers who left reviews agree that owner-managed service beats anonymous dispatch.
We’re not a franchise. Marcus Feldman is owner and Service Manager, which means ownership-level accountability is built into daily operations, not just the sales pitch. When we quote a furnace replacement on a Seacliff condo, Marcus reviews the spec himself. When a Rio del Mar beach cottage needs corrosion-resistant equipment, he’s the one making sure the coils are marine-grade.
Response time to Aptos matters because heating failures here aren’t always predictable. The marine layer keeps temperatures moderate, but when a January storm drops the mercury and your wall furnace dies, you need same-day service. We prioritize Aptos calls and carry parts for the brands we see most: Trane, Lennox, Goodman, and Rheem among them. Your system, our specialty — we service nine major brands, so you’re never told “we don’t work on that.”
Our Heating & Furnace Services in Aptos
Furnace Repair
Furnace repair in Aptos runs $150–$700 depending on the component and accessibility. We see a lot of salt-air corrosion on heat exchangers in oceanfront homes, particularly in Rio del Mar and along the Seacliff corridor, where hairline cracks can develop within 5–7 years of installation and create carbon monoxide risks. We also handle the frustrating reality of 1960s wall furnaces with cracked fireboxes and discontinued ignitors — we’ll tell you straight if parts are available or if you’re throwing money at a lost cause.

Furnace Replacement
This is where our Aptos expertise pays off most. Many Aptos homes built before 1960 still use original gravity-type floor furnaces or wall units that rely on discontinued gas-valve parts, making a simple repair impossible and forcing a full replacement to a sealed-combustion system. We serviced a 1957 beach cottage on Merritt Drive in Rio del Mar with a rusted-out gravity furnace that had a failed Carrier gas valve from the 1980s. Since replacement parts were discontinued, we retrofitted a new high-efficiency sealed-combustion furnace with epoxy-coated coils to resist salt-air corrosion, ensuring the home stays warm without risking carbon monoxide leaks. Replacement costs vary with home size and ductwork condition, but we’ll give you an exact quote after inspection.

Furnace Tune-Up
A furnace tune-up in Aptos costs $80–$200 and is essential here for reasons inland homeowners don’t face. The persistent coastal humidity creates condensation issues in crawl spaces and attics, and annual service catches corrosion before it becomes a heat exchanger failure. We check gas pressure, flame sensor operation, and — crucial for coastal homes — the condition of outdoor vent terminations and cabinet integrity. Annual corrosion-inhibitor service is a non-negotiable local standard in Aptos, not an upsell.

Heat Exchanger Inspection & Replacement
Heat exchanger failures are our most serious call in Aptos. Salt-air corrosion accelerates metal fatigue, and we’ve found cracks in units as young as five years old in beachside installations. We use combustion analyzers and visual inspection with borescope cameras to verify integrity. If replacement is needed, we’ll show you the damage and explain your options — repair, replacement, or full system upgrade. This is not a corner to cut. A cracked heat exchanger can leak carbon monoxide into your living space.

Gas Valve Repair
Gas valve issues range from intermittent ignition failures to complete valve seizure. In Aptos, we encounter a unique problem: valves on legacy wall furnaces and gravity systems where the manufacturer stopped production decades ago. We’ll attempt repair where possible, but we’re upfront when a replacement valve simply doesn’t exist. That’s when we pivot to discussing modern sealed-combustion alternatives that meet current safety codes.

Ignitor Replacement
Modern hot-surface ignitors and older pilot assemblies — we stock both. For newer furnaces in Aptos, ignitor replacement is straightforward. For 1960s wall furnaces, the conversation changes. Many original ignitor assemblies are discontinued, and retrofitting modern components to old fireboxes isn’t always safe or possible.

Trusted Brands We Service in Aptos
We service nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Aptos customers, this matters because we stock common parts locally and can often source same-day what other contractors need to order. We’ve worked on Trane systems in Seacliff condos, Lennox units in Rio del Mar rebuilds, Goodman furnaces in mid-century cottages, and Rheem equipment throughout the 95003 zip. Factory-trained compatibility means you’re never stuck with a “we don’t service that brand” brush-off. From emergency calls to commercial buildouts, we have the technical range to handle whatever system you own.
Common Heating & Furnace Problems We See in Aptos Homes
- Salt-air corrosion of heat exchangers in oceanfront homes. The marine layer that blankets Aptos carries salt that pits and corrodes outdoor equipment and vent terminations. We’ve replaced heat exchangers in five-year-old systems in Rio del Mar that looked fifteen years old. Technicians working the oceanfront blocks know to check outdoor unit coil fins with a flashlight before quoting any repair.
- Original wall furnaces in mid-century cottages with cracked fireboxes and no available replacement parts. Aptos has a significant inventory of mid-century beach cottages, many originally seasonal vacation homes now occupied year-round. These often still rely on aging wall furnaces or electric baseboard heat. When the ignitor or gas valve fails and parts are discontinued, repair isn’t an option.
- Piecemeal ductwork from earthquake retrofits that restricts airflow. Post-1989 Loma Prieta earthquake rebuilds and additions created some newer construction, but incomplete or undersized ductwork from piecemeal upgrades is a common finding on service calls. We’ve seen new furnaces cycle on their high-limit switch because duct redesign was never part of the retrofit.
- Elevated indoor humidity causing mold and corrosion in crawl spaces and attics. The persistent onshore fog drives relative humidity that standard furnaces don’t address. We regularly recommend ERVs and whole-home dehumidification as part of heating system conversations in Aptos — it’s a practical necessity, not an upsell.

FAQs — Heating & Furnace in Aptos
Salt-air corrosion from Monterey Bay accelerates metal fatigue and pitting, particularly in oceanfront neighborhoods like Rio del Mar and Seacliff where units may show severe corrosion within three to five years. The marine layer deposits salt on outdoor vent terminations and cabinet surfaces that inland systems never encounter. We spec marine-grade coated coils and recommend annual corrosion-inhibitor service for coastal installations. Call (844) 560-6978 to schedule an inspection — estimates are free.
Often no — many original ignitor assemblies and gas valves for 1960s wall furnaces were discontinued decades ago, and retrofitting modern components to old fireboxes isn’t always safe or possible. We’ll check part availability first, but if your unit uses a discontinued gas valve, replacement with a modern sealed-combustion system is usually the only viable path. Call (844) 560-6978 and we’ll tell you honestly where your system stands.
This usually indicates a limit switch issue, thermostat wiring problem, or — in Aptos specifically — restricted airflow from undersized ductwork that causes the furnace to run continuously without satisfying the call for heat. Piecemeal ductwork from earthquake retrofits is a frequent culprit in local homes. We diagnose the root cause rather than just replacing parts. Call (844) 560-6978 for same-day service.
Generally no — at 30 years, even a working furnace is well past efficient operation, and replacement parts become harder to source each year. In Seacliff specifically, salt-air corrosion likely has already compromised the heat exchanger and cabinet. We recommend putting repair money toward a high-efficiency sealed-combustion replacement with corrosion-resistant components. Call (844) 560-6978 for a free replacement quote.
We specify epoxy-coated or galvanized coils, corrosion-resistant cabinets, and proper outdoor vent termination placement to minimize direct salt spray exposure. Annual maintenance with corrosion-inhibitor application is standard practice for our Aptos installations, not optional. We’ve learned that contractors who skip these specs generate expensive warranty callbacks fast in this climate. Call (844) 560-6978 to discuss equipment options for your coastal home.
