Fast, Reliable Heating & Furnace Across San Martin
Heating & Furnace service in San Martin runs $175–$825 for repairs and $3,500–$7,500 for full replacements, with most repair calls completed same-day. We’re Crestview Heating & Air California, and our Heating & Furnace team makes the drive down Monterey Road to San Martin regularly — usually within the hour for emergency calls. Owner Marcus Feldman still runs service calls himself, so when you call (844) 560-6978, you’re talking to someone who’ll actually show up at your door, not a dispatcher three states away.
San Martin isn’t like other towns we serve. This unincorporated ranchette community sits outside PG&E’s natural gas grid, which means over half the homes here run on propane-fired furnaces — a completely different servicing reality than Morgan Hill or Gilroy. The coastal salt air drifts inland through the Santa Clara Valley, the agricultural dust from surrounding orchards and fields coats everything, and those sprawling 1960s–1990s ranch homes on 1–5 acre parcels often have ductwork that was undersized from day one. We’ve been sorting out these exact conditions for nearly two decades.
Why Crestview Heating & Air California Is San Martin’s Preferred Heating & Furnace Company
Our 4.8-star average across 250+ reviews didn’t come from easy jobs in climate-controlled suburbs. It came from showing up in places like San Martin, where the furnace problems are weirder and the solutions require actual field knowledge. Marcus Feldman, our owner and Service Manager, has 19 years of hands-on HVAC experience and still carries tools on every call. That means ownership-level accountability isn’t a slogan here — it’s who answers your call and who signs off on the work.
We recently serviced a late-1970s ranch home on East Middle Avenue where a corroded burner assembly was causing a propane Lennox furnace to short-cycle. The homeowner had no idea the coastal salt air was attacking the heat exchanger through the fresh-air intake. We replaced the burner assembly, installed a stainless steel secondary heat exchanger, and upgraded the ignitor to a silicon nitride type that resists moisture-induced cracking. That’s the kind of diagnosis you get when the owner is also the Service Manager.
San Martin’s ZIP 95046 is well within our regular service radius. We’re down Monterey Road, past the ranchettes and row crops, often enough that we keep propane orifice kits, salt-corrosion-resistant heat exchanger components, and extra blower filters stocked specifically for this market. No waiting two weeks for “special order” parts that should be standard here.
Our Heating & Furnace Services in San Martin
Furnace Repair
Most furnace repair calls in San Martin trace back to one of three local conditions: propane orifice clogging from sulfur deposits, salt-air corrosion on heat exchangers and flue pipes, or agricultural dust choking the blower compartment. A typical repair runs $150–$700 depending on what’s failed and whether we’re dealing with a standard fix or something aggravated by San Martin’s unique environment. We service Trane, Lennox, Goodman, and Rheem systems regularly, plus five other major brands — so we’re not going to tell you “we don’t work on that.”
The salt-laden coastal air that drifts through the Santa Clara Valley accelerates corrosion on furnace heat exchangers and flue pipes, causing premature failure within 8–10 years versus 15+ inland. When we diagnose a repair in San Martin, we’re checking for this specifically. It’s not the same inspection we’d run in San Jose.
Furnace Replacement
Full furnace replacement in San Martin typically costs $3,500–$7,500, with the propane fuel source being the first specification we confirm. Because so many San Martin properties lack natural gas access, we size and quote propane-compatible systems from the start — not as an afterthought. The sprawling floor plans common in 1960s–1990s ranch homes here often mean the original ductwork was undersized, so we evaluate whether your replacement needs duct modifications to actually deliver heat to every corner of the house.
Detached workshops, barns, and guest quarters on the same parcel frequently need independent HVAC solutions. We’ve done multi-system jobs on San Martin ranchettes where the main house, a guest cottage, and a workshop each needed separate propane furnaces. Owner-managed, not outsourced — Marcus specs every system himself.
Furnace Tune-Up
A furnace tune-up in San Martin runs $80–$200 and is worth scheduling twice yearly here, not just once. The agricultural dust from surrounding orchards and Gilroy’s garlic fields clogs filters and blower compartments within weeks during harvest season. Outdoor condensers on ranchette properties get buried in tractor-turned field dust every spring and fall. Technicians who don’t schedule coil-cleaning calls around the local ag calendar end up replacing units that should have lasted another decade.
We check propane pressure, burner orifice condition, and heat exchanger integrity specifically for San Martin’s corrosion and sooting patterns. This isn’t a generic checklist. It’s calibrated for what actually fails here.
Heat Exchanger & Ignitor Replacement
Heat exchanger failure in San Martin often shows up earlier than expected due to salt-air corrosion attacking the metal through fresh-air intakes. Ignitor replacement is one of our most common calls — the silicon carbide ignitors standard in many systems crack from thermal cycling aggravated by moisture, and we upgrade to silicon nitride versions that resist San Martin’s coastal humidity.
Ignitor replacement typically falls within our $150–$700 repair range. Heat exchanger replacement, when the unit is young enough to justify it, runs toward the higher end. Sometimes replacement of the full furnace makes more sense. We’ll tell you straight which it is.
Gas Valve Repair
Propane gas valves require different pressure settings and different servicing protocols than natural gas. In San Martin, we see valves sticking or failing due to sulfur residue buildup from local propane. We clean, adjust, or replace as needed — always with the correct propane-rated components, never natural gas parts swapped in desperation.

Trusted Brands We Service in San Martin
We carry factory-trained compatibility across nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. In San Martin, we see a lot of Lennox and Goodman propane furnaces in the older ranch homes, and Trane systems in some of the custom builds from the 1980s and 90s. We stock common ignitors, blower motors, and control boards for these brands locally, so most San Martin customers aren’t waiting on shipped parts. When you’re running propane heat and the temperature’s dropping, that turnaround matters.
Common Heating & Furnace Problems We See in San Martin Homes
- Propane orifice clogging from sulfur deposits. Local propane has higher sulfur content than pipeline natural gas. The burner orifices clog, combustion goes incomplete, and you get sooting, yellow flames, and carbon monoxide risk. We clean and resize orifices, or replace burner assemblies when corrosion has gone too far.
- Salt-air corrosion on heat exchangers and flue pipes. The coastal salt that drifts inland through the Santa Clara Valley attacks metal furnace components years faster than in San Jose or Santa Clara. We inspect for this specifically and specify corrosion-resistant replacements when the original has failed prematurely.
- Agricultural dust choking blower compartments and filters. San Martin’s surrounding row crops and orchards generate harvest particulate that loads filters and coats blower wheels within weeks during peak season. We schedule pre-harvest tune-ups for customers who’ve learned this lesson once.
- Undersized ductwork in sprawling ranch floor plans. Those 2,000–3,500 square foot single-story homes on 1–5 acre parcels often have duct runs that were barely adequate in 1975. The furnace works harder, cycles more, and fails sooner. We evaluate duct capacity when quoting any replacement.

What moves you within these ranges? Propane systems often need more extensive burner work than natural gas. Salt corrosion can turn a simple ignitor swap into a heat exchanger inspection. Agricultural dust loading means blower cleaning adds labor to a standard tune-up. We quote upfront before starting work — call (844) 560-6978 for a free estimate and we’ll give you a firm number for your specific system and situation.

FAQs — Heating & Furnace in San Martin
Yes — propane furnaces in San Martin need more frequent burner orifice cleaning and combustion analysis due to sulfur deposit buildup from local propane supplies. We recommend twice-yearly tune-ups here, with one scheduled before harvest season when dust loading peaks. Call (844) 560-6978 to set up a maintenance plan — estimates are free.
The combination of coastal moisture and temperature swings causes standard silicon carbide ignitors to crack from thermal stress. We upgrade San Martin customers to silicon nitride ignitors that resist moisture-induced failure. Most ignitor replacements run $150–$400 and we stock the upgraded type for same-day repair. Call (844) 560-6978 if your furnace is clicking but not firing.
Dust from surrounding orchards, row crops, and Gilroy’s garlic fields loads your blower filter and coats the blower wheel within weeks during spring and fall harvest. Restricted airflow makes your furnace work harder, run hotter, and fail sooner. We schedule pre-harvest tune-ups specifically to clean blower compartments and swap filters before damage accumulates. Call (844) 560-6978 to get on the seasonal schedule.
Yes — multi-system jobs on ranchette properties are common for us. We size propane furnaces for detached workshops, barns, and guest quarters, running separate fuel lines or tapping existing tanks as appropriate. Each building gets its own load calculation based on use, insulation, and square footage. Call (844) 560-6978 for a free estimate on your specific setup.
Propane-fired furnaces are the standard solution here, and we size, install, and service them regularly. We’ll confirm your propane tank access, pressure, and line capacity before quoting any equipment. Nearly every San Martin ranchette we’ve worked has been in this exact situation. Call (844) 560-6978 and we’ll walk through your fuel source options — estimates are free.
