We’ve been driving out to Loomis since 2012. Gregory Hahn founded this company and still leads every technical decision, and our trucks know the difference between a quick trip down Horseshoe Bar Road and a winding haul up to the larger ranchette parcels off Delmar Avenue. Loomis isn’t Roseville with trees. The housing stock is older, the lots are bigger, and about one in five homes here has no natural gas line at all. That changes everything about how we diagnose, what parts we carry, and what we recommend.
Why Redwood Heating & Air San Diego Is Loomis’s Preferred Heating & Furnace Company
Our reputation in Loomis was built one propane regulator at a time. Gregory Hahn holds a Master Technician designation, and that credential is on the truck, not in a corporate office. When you call us, you’re getting 13 years of field experience across nine major HVAC brands, not a dispatcher sending whichever crew is available.
We’ve earned 428 verified customer reviews averaging 4.6 stars, and a meaningful share of those come from Loomis homeowners who found us after a one-brand dealer couldn’t handle their propane setup. We respond to Loomis calls with the same urgency as our San Diego base because we know what a hard freeze night does to a family with a failed furnace on a rural parcel.
Our technicians understand Loomis’s specific challenges: orifice sizing for propane conversion, regulator pressure checks, and the ductwork realities of custom 1970s homes with vaulted ceilings. We don’t template our load calculations. Every Manual J we run accounts for the actual house in front of us.
Our Heating & Furnace Services in Loomis
Furnace Repair
Most furnace repair calls we get in Loomis involve propane ignition failures or erratic cycling in older units. The $150–$700 range covers the majority of repairs, from ignitor replacement to gas valve work. In the Loma Rica Ranch subdivision, we replaced a 30-year-old propane furnace where the original heat exchanger had rusted through. The home had no gas line access, so we designed a high-efficiency propane system with a cold-climate heat pump for dual-fuel operation — a solution that would be unnecessary just five miles west in Roseville’s gas-rich subdivisions. We carry propane-specific orifices, regulators, and ignition modules on our trucks because driving back to a warehouse wastes your time.
Furnace Replacement
When a furnace in Loomis hits 20-plus years, replacement usually makes more sense than chasing intermittent failures. Our Heating & Furnace team handles full replacements from $3,500–$7,500, including propane-to-propane swaps, electric conversions, and dual-fuel heat pump add-ons. The large floor plans and vaulted ceilings common in Loomis custom homes demand careful load calculation. We’ve seen too many systems installed by out-of-town contractors that short-cycle constantly because the ductwork was never designed for the actual house. We measure everything. We don’t guess.
Furnace Tune-Up
A propane furnace tune-up in Loomis runs $80–$200 and should happen annually, ideally before the first hard freeze. We check burner orifices for corrosion, test regulator pressure, inspect the heat exchanger with a borescope, and verify that safety switches actually trip. The temperature swings here — 100°F summers to genuine hard freezes — put thermal stress on components that milder climates don’t replicate. Infrequent maintenance on a propane system is how you get ignition failures at 11 PM on the coldest night of January.
Heat Exchanger Inspection & Replacement
Heat exchanger cracks are especially common in Loomis due to those extreme seasonal temperature swings. Metal expands and contracts. After 15 or 20 years of that cycling, thin spots develop. A cracked heat exchanger is a genuine safety issue — carbon monoxide can enter your living space. We inspect with visual and electronic methods, and if replacement is needed, we’ll show you exactly what we found. In many cases, especially with older propane furnaces, a full system replacement is the more cost-effective path.
Gas Valve Repair
Propane gas valves require different pressure ratings and orifice sizing than natural gas units. We’ve found valves on Loomis properties that were never properly converted, or where the original conversion kit was installed incorrectly decades ago. Proper gas valve repair and calibration prevents the sooting, delayed ignition, and rollout issues that can damage a furnace beyond practical repair.
Ignitor Replacement
Hot surface ignitors in propane furnaces fail more frequently when the system cycles on and off repeatedly — exactly what happens with undersized ductwork or poor airflow. We don’t just swap the part. We figure out why it failed.

Trusted Brands We Service in Loomis
We service your brand. Our technicians are factory-trained or field-experienced across Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Loomis customers, this matters because older custom homes often have mixed equipment — a Lennox furnace from a 1995 renovation paired with a newer Rheem AC, or a Goodman propane unit that replaced an oil burner. We don’t need to call in a specialist. We stock common ignitors, gas valves, and control boards for Trane, Lennox, Goodman, and Rheem locally, which means faster turnaround on repairs and fewer return trips.
Common Heating & Furnace Problems We See in Loomis Homes
- Propane furnace ignition failures from old regulators and orifice corrosion. Years of infrequent maintenance let moisture accumulate in propane lines. The orifice opening degrades. The pilot or ignitor can’t establish consistent flame. We see this constantly on rural Loomis parcels where the furnace hasn’t been touched since the previous owner.
- Heat exchanger cracks from thermal stress. Loomis’s 100°F-plus summers and hard-freeze winters create expansion-contraction cycles that Sacramento Valley systems simply don’t experience. We find cracks in 20-year-old furnaces that would have lasted another decade in milder climates.
- Undersized ductwork in custom-built homes with vaulted ceilings. The open-beam, high-ceiling designs popular in 1970s–1990s Loomis construction look beautiful but move air poorly. Rooms stay cold. The furnace short-cycles. The fix isn’t a bigger furnace — it’s proper duct redesign with Manual D calculations.
- All-electric heat pumps struggling below 35°F. Homes without gas lines sometimes have heat pumps that weren’t specified for cold-climate operation. When the auxiliary heat kicks in constantly, bills spike and comfort drops. We specify cold-climate rated equipment with proper low-ambient performance.
Pricing for Heating & Furnace in Loomis, CA
Here’s what heating and furnace work actually costs in Loomis. These ranges reflect our 13 years of pricing jobs across Placer County’s varied housing stock.
| Service | Typical Range in Loomis |
|---|---|
| Furnace Repair | $150 – $700 |
| Furnace Replacement | $3,500 – $7,500 |
| Tune-Up | $80 – $200 |
What moves you within these ranges? Propane systems often need regulator replacement or line pressure testing that natural gas jobs don’t. Custom homes with poor access or buried ductwork take more labor. And if we’re converting from propane to a dual-fuel heat pump setup, that’s a different scope entirely. We price upfront after diagnosis, not after the work is done. Estimates are free. Call (844) 875-9451 to schedule.
We Also Serve Cities Near Loomis
Our service area extends throughout the Placer County foothills. We regularly run calls to Rocklin, Granite Bay, Roseville, and North Auburn. Rocklin and Roseville customers tend to have natural gas infrastructure and tract-home ductwork — simpler jobs in some ways, but we bring the same diagnostic rigor. Granite Bay shares Loomis’s custom-home character. North Auburn sits higher in the foothills and sees even colder nights, making heat-pump low-ambient ratings critical there.

FAQs — Heating & Furnace in Loomis
Yes. We service propane furnaces regularly in Loomis and carry propane-specific orifices, regulators, and ignition parts on our trucks. Our technicians are trained on propane pressure settings and conversion specs that differ from natural gas. Call (844) 875-9451 to schedule — estimates are free.
A cold-climate heat pump paired with your existing propane furnace as backup is often the most efficient path for Loomis. The dual-fuel approach handles 100°F summers with efficient cooling and manages hard-freeze nights without the all-electric bill shock. We design these systems specifically for foothills temperature ranges, not valley-floor assumptions. Call (844) 875-9451 and we’ll run the numbers for your actual house.
Usually yes. Heat exchanger replacement in an older furnace often costs 60–70% of a new system, and the remaining components are still past their reliable lifespan. We inspect and document the crack, then quote both repair and replacement so you can compare. For propane systems especially, newer equipment offers better safety controls and efficiency. Call (844) 875-9451 for an honest assessment.
Yes. We size, install, and repair all-electric heat pumps for Loomis properties off the gas grid, and we specify cold-climate models with low-ambient ratings that perform below 35°F. Proper load calculation matters even more in all-electric homes because there’s no propane backup to cover a sizing mistake. Call (844) 875-9451 for a free estimate.
Annually, before winter. Propane systems need orifice inspection, regulator pressure verification, and combustion analysis that natural gas units don’t. The hard-freeze risk in Loomis foothills makes pre-season maintenance non-negotiable. Our $80–$200 tune-up covers all of this. Call (844) 875-9451 to schedule before the cold hits.
