We’re Crestview Heating & Air California, and our Heating & Furnace team knows Ontario’s homes inside and out. From the post-war tract houses near Holt Boulevard to the newer master-planned communities off the 60 Freeway, we’ve spent nearly two decades servicing the exact furnace failures this climate produces. Ontario’s location in the Inland Empire heat trap means your system works harder than most, and that wear shows up in specific ways we’ve learned to diagnose fast. Marcus Feldman, our owner and Service Manager, still runs calls personally across San Bernardino County, including regular routes to Ontario, Montclair, and Upland.
Why Crestview Heating & Air California Is Ontario’s Preferred Heating & Furnace Company
Ontario customers find us through word-of-mouth in neighborhoods like the 91762 corridor and the newer 91761 tracts near East Ontario. Our 4.8-star average across 250+ reviews reflects real jobs finished, not curated testimonials. When we say “owner-managed, not outsourced,” we mean Marcus Feldman reviews every Ontario dispatch and often arrives with the technician to assess complex jobs personally.
Response time matters in Ontario because furnace failures don’t wait for convenient weather. We maintain parts inventory for Carrier, Trane, Lennox, Goodman, and Rheem units commonly found in local homes, which means fewer return trips and faster heat restoration. Our familiarity with Ontario’s specific building stock — the 1950s–70s homes with attic ductwork, the 1990s–2000s builds with aging builder-grade equipment — lets us quote accurately and show up prepared.
Our Heating & Furnace Services in Ontario
Furnace Repair
Ontario furnaces take a beating. In central Ontario, especially around 91762, we’ve replaced heat exchangers cracked by thermal stress from attics that hit 155°F in July. Near the I-10 corridor in 91761, voltage fluctuations from industrial warehouse loads cause ignitor failures on older Lennox and Rheem units. Our furnace repair runs $150–$700 depending on the component and accessibility. We carry ignitors, gas valves, and blower motors for the nine major brands we service, so most Ontario repairs finish in a single visit.
Furnace Replacement
When repair costs approach 50% of replacement value, we’ll tell you straight. A new furnace installation in Ontario ranges from $3,500–$7,500, including removal, permitting, and ductwork modifications if needed. Homes in 91764 near Ontario Mills or the newer developments south of the 60 often need upgraded electrical connections or plenum adjustments to accommodate modern high-efficiency units. We size every replacement to Ontario’s actual heating load, not the original 1960s calculation.
Furnace Tune-Up
Our $80–$200 tune-up includes burner inspection, heat exchanger check, gas pressure test, and ductwork assessment. In Ontario, we pay special attention to attic duct sealing because those 150°F summer temperatures degrade flexible duct connections and cause furnaces to work harder all winter. A tuned furnace in Ontario’s 91762 area typically runs 15–20% more efficiently than a neglected unit in the same neighborhood.
Heat Exchanger Repair & Replacement
We recently serviced a 1962 split-level on Plum Avenue in Ontario’s 91762, where the furnace’s heat exchanger cracked due to thermal stress from 155°F attic temps. We replaced it with a high-efficiency Carrier gas furnace and sealed the ductwork to handle the extreme heat differentials typical of this neighborhood. Heat exchanger failures are serious — carbon monoxide risk means we never patch and pray. If we find cracks, we shut the unit down and explain your replacement options clearly.
Ignitor Replacement
Hot surface ignitors fail regularly in Ontario’s warehouse-adjacent neighborhoods where voltage sags from industrial equipment create premature wear. We stock ignitors for Goodman, Rheem, Lennox, and Trane units common in 91761 and 91764. Replacement typically runs $150–$400 including diagnostic. We’ll also check your electrical supply if we see patterns suggesting upstream issues.
Gas Valve Repair
Construction dust from ongoing development in 91761’s master-planned communities has caused an uptick in gas valve sediment clogging. A failing gas valve produces weak burner flames, delayed ignition, or complete shutdown. We clean or replace valves and test gas pressure at the manifold to confirm proper operation. This repair falls within our standard $150–$700 furnace repair range.

Trusted Brands We Service in Ontario
Your system, our specialty. We factory-train on Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard — the nine brands most commonly installed in Ontario homes. Our parts van stocks ignitors, gas valves, blower motors, and control boards for Goodman, Rheem, and Lennox units we see most often in 91761 and 91762. That inventory means Ontario customers wait hours, not days, for repairs that other companies have to order.
Common Heating & Furnace Problems We See in Ontario Homes
- Rusted heat exchangers from Santa Ana moisture swings. October and November temperature spikes to 90°F+ followed by rapid cooling create condensation cycles in attic-mounted furnaces. We’ve replaced more heat exchangers in Ontario’s 91762 in October than any other month.
- Ignitor failures from industrial zone voltage fluctuation. Homes near the I-10/I-15 warehouse corridor experience more electrical instability than inland neighborhoods. We see premature ignitor failure on 8–12 year old Lennox and Rheem units in this zone.
- Gas valve sediment from construction dust. The ongoing buildout in 91761’s eastern tracts pumps fine particulate into HVAC intakes. Gas valves clog, pilot assemblies foul, and burner orifices narrow. Annual tune-ups catch this before failure.
- Undersized ductwork causing furnace overwork. Central Ontario’s 1950s–70s homes were built for smaller systems. Modern furnaces pushing through 60-year-old ductwork cycle on and off excessively, cracking heat exchangers and burning out blowers.

FAQs — Heating & Furnace in Ontario
Santa Ana winds blast through the Cajon Pass and hit Ontario with 90°F+ temperatures in October and November, forcing homeowners to switch cooling systems back on after “winterizing” them. This rapid cycling between heating and cooling modes stresses heat exchangers, ignitors, and control boards in furnaces that haven’t run consistently since spring. We see our highest volume of emergency furnace calls in Ontario during these wind events. Call (844) 560-6978 if your system won’t fire up — estimates are free.
Probably, at least partially. Original ductwork in 91762’s 1960s tract homes was sized for smaller systems and routed through attics that now exceed 150°F in summer. That heat degrades flexible duct connections and forces modern furnaces to overwork. We assess ductwork during every replacement quote and typically recommend sealing or replacing the attic trunk lines. The investment usually pays back in 3–5 years through efficiency gains. Call for a ductwork evaluation — estimates are free.
Goodman, Rheem, and Lennox dominate the 1990s–2000s master-planned homes in 91761. These builder-grade installations are now 15–25 years old and hitting predictable failure points: ignitor degradation, blower motor bearing wear, and control board capacitor failure. We stock parts for all three brands and complete most 91761 repairs same-day. Call (844) 560-6978 to confirm parts availability for your specific model.
Townhomes near Ontario Mills and along the 60 Freeway corridor often have furnace closets with minimal working space, sometimes less than 24 inches clearance. We measure everything during our free estimate and specify compact high-efficiency units or horizontal flow configurations when vertical space is constrained. Our crew has installed in Ontario townhome clearances as tight as 18 inches. We’ll tell you upfront if your space requires creative solutions — no surprises after we start.
Yes, especially for homes in 91762 and 91764 with older 80% AFUE units. Ontario’s extended heating season — furnace runs from November through March, plus those Santa Ana fallback weeks — means efficiency gains compound. A 96% AFUE furnace typically saves Ontario homeowners $200–$400 annually versus an 80% unit, with faster payback than in milder coastal climates. We calculate exact payback during your free estimate based on your home’s size and current usage. Call (844) 560-6978 to run the numbers.
