Call us at (844) 560-6978 for a free estimate.
Upland sits at the base of the San Gabriel Mountains where cold air drains nightly out of Cucamonga Canyon. That creates a dramatic north-south split: foothills homes in 91784 regularly see winter nights dip near or below freezing while the southern flats in 91786 bake at 105°F+ in summer. Your system, our specialty — we’ve spent nearly two decades working on equipment that has to survive both extremes.
Why Crestview Heating & Air California Is Upland’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 furnace quits on a 38°F January night in northern Upland and knowing exactly why that 15-year-old Carrier failed. Owner Marcus Feldman still manages jobs in the field as Service Manager, so ownership-level accountability isn’t a slogan — it’s who answers the phone and who checks the heat exchanger.
We’ve been in the HVAC industry for 19 years. That means we’ve worked on virtually every system type, age, and brand you might own. We service nine major brands including Trane, Lennox, Goodman, and Rheem, so you’re never told “we don’t work on that.” From emergency calls to commercial buildouts, we bring the technical range to handle whatever your Upland property needs.
Our response time to Upland is built around understanding that heating failures here aren’t just uncomfortable — they’re genuinely dangerous when overnight lows in the foothills drop below freezing. We prioritize calls from 91784 and 91786 zip codes, and we know the difference between a ranch home on Foothill Boulevard with 1950s ductwork and a custom build in the northern hills that needs proper zoning.
Our Heating & Furnace Services in Upland
Furnace Repair
Furnace repair in Upland demands more than swapping a part. The Santa Ana winds that funnel through Cucamonga Canyon pull attic dust into furnaces, clogging flame sensors and causing nuisance lockouts within days of a wind event. We don’t just clean the sensor — we check the return path, seal duct leaks that draw dusty attic air, and test combustion after the repair because Upland’s dual-season load means your furnace works harder than equipment in flatter neighboring cities.
Most furnace repairs in Upland fall between $150–$700. A failed ignitor on a cold morning runs toward the lower end. A gas valve replacement or control board failure trends higher. We diagnose before we quote, and estimates are free.
Furnace Replacement
Upland’s northern 91784 ZIP freeze-line sees winter lows that force heat-pump emergency heat strips to cycle daily, while the southern 91786 flats regularly hit 105°F+ — a 40° range that makes dual-fuel systems far more valuable here than in Ontario or Montclair. When we size a replacement furnace for your Upland home, we calculate heating load against those canyon-cooled nights, not just average Inland Empire temperatures.
The 1950s–1970s ranch-style tract homes dominating central and southern Upland often have original or first-replacement ductwork routed through superheated attics with undersized air handlers. A new furnace without addressing that airflow restriction will crack its heat exchanger just like the old one did. Our replacement quotes include duct assessment because we’re not interested in installing equipment that fails early.
Furnace replacement in Upland typically runs $3,500–$7,500 depending on efficiency rating, size, and whether duct modifications are needed.
Furnace Tune-Up
A furnace tune-up in Upland isn’t a generic checklist. We inspect heat exchangers for pitting caused by condensation from freezing overnight downslope drafts in 91784 — damage that standard 80% furnaces suffer faster here than in lower-elevation markets. We test flame sensors for dust sensitivity because we know another Santa Ana event is coming. And we measure temperature rise across the coil because undersized return ducts in those ranch homes restrict airflow and overheat the exchanger.
Tune-ups run $80–$200. For Upland’s dual-extreme climate, we recommend pre-season maintenance before both heating and cooling seasons.
Heat Exchanger Inspection & Replacement
On a December morning in northern Upland’s foothills (91784), we replaced a rusted-through heat exchanger in a 15-year-old Carrier gas furnace; the homeowner had smelled gas for weeks because the secondary exchanger cracked from the nightly freeze-thaw cycle unique to the Cucamonga Canyon cold drain. That’s the kind of failure pattern you learn only by working in Upland.
Heat exchanger cracks are serious safety hazards — carbon monoxide can leak into your living space. We inspect with visual, combustion, and when warranted, camera examination. If replacement is needed, we match the new exchanger to your system’s capacity and check that condensate drainage won’t repeat the corrosion pattern.
Ignitor Replacement
Hot surface ignitors fail from thermal cycling, and Upland’s cold-start demand — furnaces kicking on at full output after sitting idle through a 70°F day — accelerates that wear. We stock ignitors for Goodman, Rheem, Lennox, and other major brands so Upland customers aren’t waiting on parts during a cold snap.
Gas Valve Repair
Gas valve failures in Upland often trace back to debris from Santa Ana dust events or moisture from condensation in 91784’s freeze zone. We test valve operation, gas pressure, and regulator function as an integrated system because a valve that opens but doesn’t meter correctly is just as dangerous as one that won’t open at all.

Trusted Brands We Service in Upland
We service equipment from nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Upland customers, that means we stock common parts locally and can often source same-day replacements for Trane ignitors, Lennox heat exchangers, Goodman gas valves, or Rheem control boards. Your system, our specialty — we didn’t pick nine brands to sound impressive. We did it because Upland homeowners own all nine, and “we don’t work on that” isn’t something you’ll hear from our technicians.
Common Heating & Furnace Problems We See in Upland Homes
- Santa Ana wind dust loading. The downslope and Santa Ana wind events that funnel through the Cucamonga Canyon gap can load a brand-new HVAC filter to near-failure in days and create enough negative attic pressure to pull flex-duct joints apart. Northern Upland technicians commonly find separated duct connections and debris-choked coils as the first post-wind-event call of the season.
- Freeze-thaw heat exchanger cracking in 91784. Freezing overnight downslope drafts in the northern foothills cause condensation on heat exchangers that accelerates pitting and cracking in standard 80% furnaces. We’ve replaced more secondary heat exchangers in north Upland than in any other Inland Empire city we serve.
- Undersized return duct overheating. The 1950s–1970s ranch homes throughout 91786 have return ducts sized for smaller furnaces. When a modern high-output unit pulls against that restriction, the heat exchanger overheats and trips the limit switch on the coldest mornings — right when you need heat most.
- Nuisance flame sensor lockouts after wind events. Dust pulled into the furnace cabinet coats the flame sensor within days of a Santa Ana event. The furnace lights, the sensor can’t confirm flame, and the control board shuts down the gas valve. Upland customers call us thinking they need a major repair; often they need thorough cleaning and a filter upgrade.

FAQs — Heating & Furnace in Upland
Short cycling in northern Upland’s 91784 ZIP usually traces to restricted airflow or a safety shutdown. The most common cause we find is a dirty flame sensor coated with Santa Ana dust, or an overheated heat exchanger tripping the high-limit switch because undersized returns can’t move enough air. Freezing overnight downslope drafts also cause condensation that corrodes exchanger surfaces, leading to irregular combustion. Call (844) 560-6978 and we’ll diagnose whether it’s a $150 sensor cleaning or a heat exchanger issue requiring replacement.
A dual-fuel system — heat pump with gas furnace backup — is usually the best value for Upland’s 40° temperature swing between northern foothill winters and southern flat summers. Heat pumps alone struggle below 35°F, which 91784 hits regularly. Straight gas furnaces waste efficiency potential during Upland’s mild shoulder seasons. We size dual-fuel setups based on your specific elevation and exposure to canyon drainage. Call for a load calculation and free estimate.
You need a furnace properly matched to your ductwork, not necessarily a special model. Most 1960s Upland ranches in 91786 have returns sized for 60,000–80,000 BTU output, but homeowners or prior contractors often installed 100,000+ BTU units. That mismatch overheats the exchanger and trips limits. We measure static pressure and airflow before recommending any equipment. Sometimes the right fix is a smaller furnace plus duct modifications, not a bigger one.
During Santa Ana wind season, typically October through March, check your filter monthly. Upland’s canyon gap funnels extraordinary dust loads that can choke a standard 1-inch pleated filter in three weeks. Northern foothills homes with more tree pollen and mountain debris may need even more frequent changes. We recommend MERV 11 minimum during wind season, with a spare filter on hand. A $15 filter change prevents $400+ sensor and coil cleanings.
Our Upland tune-up covers combustion analysis, heat exchanger inspection for freeze-thaw pitting, flame sensor cleaning and sensitivity test, gas pressure and valve operation check, blower amp draw and capacitor test, limit switch verification, thermostat calibration, and filter assessment. We also inspect duct connections for separation from wind-driven attic pressure. The appointment takes 60–90 minutes and costs $80–$200. Call (844) 560-6978 to schedule before the next cold snap.
