We’ve been driving out to Loomis since 2009. Jason Trent, our owner and field supervisor, knows the difference between a Rocklin tract home and a Loomis horse property on five acres with a propane tank behind the barn. That matters when your furnace quits at 11 PM and the tech needs to understand LP gas regulators, not just natural gas lines. Loomis sits at 400–500 feet in the western Sierra foothills, catching the same 100°F+ Sacramento Valley summer heat but cooling off sharper at night and hitting harder freezes than the valley floor. Your system works harder here, and it works differently.
Our Heating & Furnace team covers the 95650 ZIP and surrounding Placer County foothill properties. We carry factory-authorized parts for Carrier, Bryant, and American Standard, and we’ve built relationships with regional distributors for LP-specific components that aren’t always on suburban warehouse shelves.
Why Stonegate Heating & Air California Is Loomis’s Preferred Heating & Furnace Company
Sixteen years in business and nearly 500 verified reviews at 4.7 stars mean we’ve earned repeat calls from Loomis homeowners who’ve learned the hard way that not every HVAC contractor understands propane systems. Jason Trent supervises every project personally. He’s not in a back office; he’s on your property, checking manifold pressure on a propane furnace or verifying heat exchanger integrity in an attic unit that’s been baking at 140°F since June.
Loomis customers tell us the same thing: they called us because the last company sent a kid who’d never seen an LP conversion kit. We’ve heard it on Horseshoe Bar Road, on Taylor Road, and up in the Valley Oak canopy off King Road. Our response time to Loomis averages under 90 minutes for emergency calls placed before 3 PM, and we stock common gas valves, ignitors, and heat exchanger sections for 1980s-era Rheem and Goodman units that still heat half the ranches in this town.
The rural character of Loomis means we often service a main house, a detached workshop, and a barn or guest quarters on the same property. That’s three separate systems, sometimes three different fuel types, and one invoice. Suburban contractors who optimize for single-family tract homes don’t build that into their dispatch model. We do.
Our Heating & Furnace Services in Loomis
Furnace Repair
Most Loomis furnace repairs fall between $150–$700. The call starts with combustion analysis and a heat exchanger inspection. On propane systems, we check regulator output pressure and LP line moisture traps, because moisture in propane lines corrodes gas valves faster than natural gas ever will. We’ve replaced failed valves on 30-year-old Rheem units where the part had been discontinued, and we’ve sourced aftermarket equivalents that buy homeowners another heating season while they decide on replacement. If your furnace is cycling short, blowing cold, or throwing error codes, we’ll diagnose it on the first visit and give you a written quote before touching a wrench.

Furnace Replacement
A full furnace replacement in Loomis typically ranges from $3,500–$7,500 depending on capacity, efficiency tier, and whether we’re adapting from propane to a dual-fuel heat pump configuration. Loomis’s wider diurnal temperature swing, hard winter freezes, and hot summers make dual-fuel systems increasingly popular on horse properties. The heat pump handles moderate heating and all cooling; the propane furnace kicks in below 35°F when heat pump efficiency drops. Our team recently serviced a 1980s ranch on Horseshoe Bar Road where a legacy Rheem propane furnace had a failed gas valve, the original part had been discontinued, and the homeowner preferred upgrading to a dual-fuel heat pump that could handle Loomis’s hard winter freezes while still burning propane when needed. We sized the system for the home’s actual load, not a rule-of-thumb square-footage guess.

Furnace Tune-Up
Tune-ups run $80–$200 and should happen every fall before the first hard freeze. In Loomis, that freeze often comes in late November, earlier than Roseville or lower Sacramento. Our tune-up covers combustion analysis, gas pressure verification, heat exchanger inspection with a borescope, blower amp draw, and thermostat calibration. On propane systems, we pull and inspect the regulator vent screen, check for moisture in the drip leg, and verify orifice condition. We also inspect attic ductwork for rodent damage and collapsed flex runs. Unconditioned attics in Loomis hit 140°F+ in summer; that thermal cycling degrades duct seams and insulation. Catching it in fall means you’re not bleeding heat into a dusty attic all winter.

Heat Exchanger Inspection & Replacement
A cracked heat exchanger is a safety shutdown. No exceptions. In Loomis’s older housing stock, 1970s and 1980s furnaces have heat exchangers that have cycled through 30+ years of expansion and contraction. We inspect with a borescope camera, document findings with photos, and explain exactly what we’re seeing. Replacement heat exchangers are available for some models, but on high-hour propane furnaces where the burner assembly and gas valve are also near end-of-life, we’ll give you honest numbers on repair-versus-replace. Propane burns hotter than natural gas; that extra flame temperature accelerates metal fatigue. It’s a real factor in Loomis that doesn’t come up in Rocklin subdivisions with NG service.

Gas Valve Repair
Propane gas valves fail from moisture corrosion, debris from aging LP tanks, and overpressure events when regulators malfunction. We test inlet and outlet pressure, check coil resistance, and verify proper shutoff delay. If the valve is rebuildable, we’ll say so. If it’s a discontinued part on a 1985 furnace, we’ll tell you that too, and we’ll have replacement options ready. Loomis homeowners with propane systems learn fast that not every HVAC tech carries LP-specific test gear. We do.

Ignitor Replacement
Hot surface ignitors on modern furnaces, and pilot assemblies on older units, both fail with age. Propane’s higher BTU content and different flame characteristics mean the ignitor and flame sensor need proper gap and positioning for LP, not just NG defaults. We measure microamps at the flame rod and adjust as needed. A weak flame signal in a propane furnace will lock you out on the coldest night of the year.

Trusted Brands We Service in Loomis
We maintain factory training and parts access for nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Loomis customers, that means no dead-end “we don’t service that brand” conversation. We stock common ignitors, gas valves, and control boards for Carrier and Bryant systems at our Sacramento warehouse, and we’ve built direct relationships with regional distributors for LP-specific components on Rheem and Goodman propane furnaces. Turnaround on most parts is 24–48 hours; same-day completion happens when the failure mode is predictable and the part is on our truck. That’s the advantage of 16 years in this market. We know what fails on Loomis’s 1980s ranches because we’ve already fixed it on the next street over.
Common Heating & Furnace Problems We See in Loomis Homes
- Propane gas valves and regulators corrode from moisture in LP lines. Loomis’s semi-rural horse properties frequently rely on propane rather than natural gas, and tanks that aren’t serviced annually accumulate moisture that works its way into the gas valve. The valve sticks, leaks, or fails to open fully. We check the drip leg and regulator vent on every propane service call.
- Blue Oak leaf litter and acorns pack outdoor condenser coils by mid-summer. Valley Oaks and Blue Oaks dominate nearly every Loomis property, and the spring pollen load plus year-round acorn debris and leaf litter clog outdoor condenser coils far faster than in adjacent suburban Rocklin. Local techs know that skipping the annual coil flush here means a compressor call by mid-July. We include coil cleaning in every tune-up.
- Uninsulated ductwork in 140°F+ attics loses efficiency and develops leaks. Loomis’s custom ranch homes built before modern Title 24 standards commonly route flex duct through unconditioned attic spaces. The insulation degrades, seams separate, and you’re heating your attic instead of your living room. We inspect with thermal imaging and seal or replace as needed.
- Rodents puncture flex ducts in barns and guest houses. Detached workshops, barns, and guest quarters are common on Loomis horse properties and frequently represent a secondary HVAC service need on the same job. Field mice and roof rats chew through flex duct in outbuildings where the duct runs through crawl spaces or unsealed chase ways. We find the damage, repair with rodent-resistant hard duct where appropriate, and seal entry points.
Pricing for Heating & Furnace in Loomis, CA
Here’s what heating and furnace service costs in the Loomis market:
| Service | Price Range |
|---|---|
| Furnace Repair | $150–$700 |
| Furnace Tune-Up | $80–$200 |
| Furnace Replacement | $3,500–$7,500 |
What moves the needle within these ranges? Accessibility matters. A furnace in a tight attic crawl space takes longer to service than one in a garage closet. Propane systems require additional safety checks and LP-specific test equipment. Parts availability on discontinued 1980s models can extend timeline and cost if we need to source aftermarket or cross-reference equivalents. And dual-fuel heat pump conversions involve electrical panel assessment, line set sizing, and thermostat configuration that a straight furnace swap doesn’t.
We don’t quote over the phone for replacement work. Every Loomis home is different, especially the custom ranches with additions, detached buildings, and unique duct layouts. Our estimates are free, detailed, and delivered in writing. Call (855) 467-1888 to schedule.

FAQs — Heating & Furnace in Loomis
Yes, we regularly source parts for legacy Rheem propane furnaces in Loomis, including aftermarket gas valves, ignitors, and heat exchanger sections when factory parts are discontinued. We cross-reference part numbers against current production equivalents and maintain relationships with regional distributors who specialize in obsolete HVAC components. If a part is truly unavailable, we’ll give you replacement options with exact pricing before proceeding. Call (855) 467-1888 with your model and serial number.
Yes, Loomis’s wide diurnal temperature swing and hard winter freezes make dual-fuel systems an excellent fit for propane properties. The heat pump handles cooling and moderate heating efficiently; the propane furnace engages below 35°F when heat pump capacity drops. We’ve installed several dual-fuel conversions on Horseshoe Bar Road and Taylor Road properties where homeowners wanted to reduce propane consumption without sacrificing freeze protection. Jason Trent evaluates each home’s heat load, existing ductwork, and electrical panel capacity before recommending this configuration.
Your Loomis property is almost certainly shaded by Valley Oaks or Blue Oaks, and the spring pollen, acorn debris, and leaf litter produced by these trees clog condenser coils two to three times faster than in suburban Rocklin with its manicured lawns and limited canopy. The debris insulates the coil, raises head pressure, and forces the compressor to work harder until it fails. An annual coil flush in May, before the 100°F days arrive, prevents this. We include it in every tune-up.
It’s common in Loomis but not ideal. Attics in Loomis’s older homes regularly exceed 140°F in summer, which thermally stresses the heat exchanger, control board, and blower motor. Flex duct in unconditioned attic spaces also loses efficiency as insulation degrades. We inspect for proper clearance, combustion air supply, and safe condensate drainage on every attic furnace call. If your system is due for replacement, we’ll discuss whether relocating to a conditioned space or upgrading to a high-efficiency sealed combustion unit makes sense for your home.
Yes, we routinely service multiple systems on the same Loomis property, including main houses, detached workshops, barns, and guest quarters. Many Loomis horse properties have two or three separate HVAC systems with different fuel types and ages. We schedule adequate time, bring appropriate parts for each unit, and bill for actual work performed rather than charging separate trip fees. Mention the additional systems when you call (855) 467-1888 so we dispatch accordingly.
