Claremont isn’t like other Inland Empire cities. The pre-WWII bungalows around the Village, the gravity-fed systems near Pomona College, and the foothill homes north of Baseline Road each present heating challenges that require real field experience, not a dispatcher reading from a script. We’ve worked on systems in Claremont that most technicians under 40 have never seen in person.
Why Crestview Heating & Air California Is Claremont’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 a 1920s gravity furnace failed on a January night, when a Santa Ana cold snap pushed a 40-year-old gas valve past its limit, when a Claremont Colleges facilities manager needed steam-to-hot-water integration without shutting down a building. 250+ customers who left reviews agree: owner-managed, not outsourced, makes a difference.
Marcus Feldman holds the title of Service Manager, which means he answers the phone, assigns the crew, and checks the work. No layers. No “we’ll have someone call you back.” When you call (844) 560-6978, you’re talking to someone with skin in the game.
We know the 91711 ZIP code well. We’ve replaced furnaces in the historic district near Harvard Avenue, tuned up systems in the College Heights neighborhood, and handled emergency calls in the foothill developments off Mount Baldy Road. Claremont’s orographic heat effect, where air stalls against the San Gabriel Mountains and drives temperatures 5–10°F higher than Pomona just 10 miles west, creates thermal stress that shortens equipment life. We factor that in when we size replacements and recommend maintenance intervals.
Our Heating & Furnace Services in Claremont
Furnace Repair in Claremont
Furnace repair in Claremont runs $150–$700 depending on the component and system age. The most common calls we get involve ignitor failures and gas valve problems, often triggered by rapid cycling during Santa Ana wind events. Those sudden October and November cold snaps force aging furnaces to fire up after months of dormancy, and the thermal shock cracks brittle ignitors or jams sticky gas valves. In the Village and near the Claremont Colleges, we also see cracked heat exchangers in 1940s-era gravity furnaces where repair parts have been obsolete for decades. We’ll tell you honestly when a repair is throwing good money at bad equipment.

Furnace Replacement in Claremont
Furnace replacement in Claremont costs $3,500–$7,500, with the wide range reflecting whether your home has existing ductwork or needs a full retrofit. This is where Claremont’s housing stock gets interesting. The Craftsman bungalows and Spanish Colonial Revival homes near the Village were built without ducts. We’ve done attic duct retrofits, crawl-space runs, and mini-split conversions that avoid wall demolition entirely. For 1970s–1990s foothill homes north of Baseline Road, replacement is usually straightforward swap-out of end-of-life equipment, though we often find undersized ductwork from original construction that needs addressing. We recently replaced a failing 1950s gas gravity furnace in a Craftsman bungalow on College Avenue near Pomona College. The homeowner opted for a modern Carrier high-efficiency furnace with duct modifications, avoiding a costly steam-to-hot-water conversion. Our crew worked around the original masonry flue to maintain the home’s character while boosting heating efficiency.

Furnace Tune-Up in Claremont
A furnace tune-up in Claremont costs $80–$200 and should happen every fall before Santa Ana season. We clean burners, test gas pressure, check heat exchanger integrity, and verify blower amp draw. In Claremont’s extreme heat pocket, where summer thermal load pushes equipment hard, fall maintenance catches the wear that accumulated during months of near-continuous operation. Homes near the Colleges with steam or gravity systems need slightly different checklists, we inspect condensate drainage, test safety controls, and verify venting integrity on converted systems.

Heat Exchanger Repair & Replacement in Claremont
Heat exchanger failure is the end of the road for most furnaces, especially in Claremont’s older housing stock. The original gravity furnaces and early gas conversions in Village homes used heavy-gauge steel heat exchangers that last 60–80 years but eventually crack from thermal cycling. Once cracked, carbon monoxide risk makes replacement mandatory, not optional. We don’t sugarcoat this. A new heat exchanger in a 30-year-old furnace is usually a bad investment. We’ll show you the crack, explain the CO risk, and give you replacement options that fit your home’s configuration. For historic homes, we often recommend high-efficiency sealed-combustion units that can vent through sidewalls, eliminating the need to rebuild an aging masonry chimney.

Trusted Brands We Service in Claremont
Your system, our specialty. We service nine major HVAC brands, and for Claremont customers we regularly stock parts for Trane, Lennox, Goodman, and Rheem, the brands we see most often in local homes. Factory-trained compatibility means we’re never telling you “we don’t work on that.” Whether it’s a 1990s Lennox pulse furnace in a foothill ranch or a newer Rheem modulating unit near the Colleges, we’ve got the technical literature and common failure patterns in our heads from 19 years in the field. Parts availability matters in Claremont because Santa Ana events don’t wait for shipping. When we can source locally and complete same-day, we do.
Common Heating & Furnace Problems We See in Claremont Homes
- Cracked heat exchangers in original gravity furnaces. The 1920s–1940s homes near the Claremont Village and Colleges have original equipment with heavy-gauge steel fireboxes that finally give out after 80+ years of expansion and contraction. Repair parts are obsolete. Replacement with a modern sealed-combustion furnace or ductless heat pump is the only safe path.
- Santa Ana wind cycling burns out ignitors and gas valves. Those sudden fall cold snaps, with 90°F days dropping to 40°F nights, force rapid on-off cycling in furnaces that haven’t run since spring. Ignitors crack. Gas valves stick. Blower motors overheat from short-cycling. Maintenance before October prevents most of these.
- Undersized ductwork in retrofitted older homes. When a Village bungalow gets a forced-air furnace added to original gravity-heat ductwork, the passages are too large and too leaky. The furnace blower works overtime, premature motor and capacitor failure follows. We resize and seal ductwork as part of replacement.
- Steam boiler failures in Craftsman homes near Scripps and Pomona Colleges. Original 1940s steam systems with rusted wet returns, failed traps, or cracked boiler sections. The question is always: repair with a modern steam boiler (possible but specialized) or convert to hot water or forced air (more disruptive but opens efficiency options).
Pricing for Heating & Furnace in Claremont, CA
Here’s what heating and furnace service costs in Claremont’s market. These are real ranges based on jobs we’ve completed in the 91711 area, not teaser rates that balloon on site.
| Service | Price Range in Claremont |
|---|---|
| Furnace Repair | $150 – $700 |
| Furnace Replacement | $3,500 – $7,500 |
| Furnace Tune-Up | $80 – $200 |
What moves you within these ranges? System age and accessibility matter most in Claremont. A standard ignitor swap on a 1990s furnace in a foothill garage? Lower end. A gravity-furnace removal with asbestos abatement and new ductwork in a Village bungalow? Higher end. Brand and efficiency rating affect replacement cost, a 96% AFUE modulating Lennox costs more than a standard 80% Goodman, but the utility rebate math often favors the upgrade. We give upfront pricing before any work starts. Estimates are free. Call (844) 560-6978 to schedule.

FAQs — Heating & Furnace in Claremont
Yes, you have two main paths: an attic duct retrofit with flexible duct runs to ceiling registers, or a ductless mini-split heat pump system that uses wall-mounted heads and no ductwork at all. We’ve done both in Village bungalows. Attic retrofits typically run $3,500–$5,500 on top of the furnace itself. Ductless systems cost more per ton but avoid any wall demolition. Call (844) 560-6978 and we’ll assess your joist layout and insulation to recommend the cleaner fit for your home.
Replace it, in nearly every case we’ve seen. Steam boiler repair parts for residential systems are increasingly obsolete, and a cracked section or failed wet return usually signals systemic corrosion. A modern steam boiler replacement is possible but requires a contractor who understands steam, a rarity in Southern California. Most Claremont homeowners opt for a forced-air furnace with new ductwork, or a ductless heat pump, to gain air conditioning capability that steam heat never provided. The upfront cost is higher than repair, but the efficiency gain and elimination of steam maintenance typically pay back within 8–12 years. Call for a free assessment of your specific system.
A standard gas furnace replacement in a 1970s–1990s foothill home typically runs $3,500–$5,500 in Claremont, assuming existing ductwork is adequate. These homes usually have original sheet-metal ductwork that’s undersized by modern standards. If we need to add returns, resize trunk lines, or seal significant leakage, costs move toward $5,500–$7,500. We test static pressure and airflow before quoting to avoid surprises. For an exact quote on your Baseline Road-area home, call (844) 560-6978, estimates are free.
Rapid cycling during Santa Ana events happens because your furnace is overheating and hitting its high-limit safety switch. The most common cause in Claremont is a dirty filter or restricted return airflow, the extreme dry air and dust during Santa Ana conditions clog filters faster than normal. Less commonly, a failing blower motor or cracked heat exchanger triggers the same protective shutdown. Rapid cycling is hard on every component and drives up gas bills. Schedule a tune-up before Santa Ana season, we check airflow, limit switch function, and heat exchanger integrity. If you’re cycling now, call (844) 560-6978 before a minor issue becomes a dead furnace.
Yes. The Claremont Colleges’ older campus buildings with steam-to-hot water conversions require careful integration of modern forced-air or hydronic equipment with legacy infrastructure, and this institutional retrofit complexity is essentially unique in the surrounding Inland Empire market. We’ve worked on systems where a modern Lennox furnace or rooftop unit must communicate with existing hot water coils, pneumatic controls, or building automation systems from another era. It’s not residential work, and most residential-only contractors in neighboring cities have never developed this skill set. Marcus Feldman oversees commercial jobs personally. For Claremont Colleges facilities or similar institutional properties, call (844) 560-6978 to discuss your specific mechanical room configuration.
