Ameristar Construction in Los Serranos, CA | Elmwood Contractors
We provide independent Ameristar sales & service across Los Serranos, from HVAC equipment platforms to full re-roofs. The short version: we fix and replace Ameristar furnaces, condensers, and roofing systems on hillside and canyon-adjacent homes where grading, drainage, and Santa Ana wind exposure change how the work has to be done. Call (866) 253-8554 for a straight answer and a free estimate.
We’re Elmwood Contractors, led by Nolan Shepherd. We’ve run Ameristar repairs and re-roofs in Los Serranos long enough to know what flatland contractors miss here. This page explains what that means for your home, your equipment, and your budget.
Why Los Serranos Residents Choose Us for Ameristar Service
Most contractors can swap a furnace or nail down shingles. Few can tell you why your Ameristar condenser pad settled three inches after one winter storm, or why your furnace flame sensor keeps failing every time the wind kicks up off Carbon Canyon. We can, because we’ve worked these hillside lots for years.
We use OEM Ameristar parts for coils, control boards, and furnace components when the unit’s remaining life justifies it. For commodity items like capacitors, contactors, and flue boots, we use quality aftermarket equivalents that cost less and perform the same. That’s the honest repair-versus-replace math we bring to every Los Serranos job.
Nolan grew up in Fullerton’s Sunny Hills neighborhood, where half the houses on his street were built in the late ’60s. By the time he was a teenager, he already knew which ones were going to have foundation problems. That early eye for how soil, slope, and water move around a house has shaped how we approach every Ameristar project in Los Serranos.

Common Ameristar Construction Problems We Solve in Los Serranos
- Ameristar condenser coils packed with dust and grit. Hot dry summers bake the coil fins, and Santa Ana winds off the foothills drive fine grit into the condenser. On hilltop lots near Carbon Canyon, we see fin erosion that flatland Chino or Ontario units never experience. We clean, repair, or replace coils based on what the remaining unit life actually justifies.
- Ameristar 80% gas furnaces tripping on flame sensors after wind events. Garage and closet chases on canyon-adjacent lots collect wind-blown dust and debris. That dust coats the flame sensor and inducer, causing failures that a flatland install wouldn’t see for years. We replace the sensor, clean the inducer assembly, and seal the chase so it stops recurring.
- Ameristar architectural shingles losing tab adhesion on windward slopes. Hillside homes off Los Serranos Country Club take asymmetric wind uplift. The windward slope loses shingle tabs, and the next winter storm drives water in at the furnace flue boot and HVAC platform penetration. We re-roof with proper underlayment and flashing, not just new shingles.
- Ameristar condenser pads settling and tilting on graded hillside soil. Heavy winter rain saturates the fill under the pad. The pad shifts, the line set stresses, and the disconnect conduit pulls at the wall penetration. We re-level the pad, re-support the line set, and correct the drainage so it doesn’t happen again.
- Water intrusion at Ameristar furnace flue boots after storms. On hillside re-roofs, the flue boot is often the first failure point. Old sealant cracks, the boot lifts, and water follows the pipe straight into the garage-chase air handler below. We replace the boot and re-flash the penetration as part of any Ameristar roof repair.
Ameristar Service in Los Serranos: What Local Conditions Mean for Your Equipment
Los Serranos sits inside Chino Hills’ hillside and grading ordinance envelope, and that single fact changes every Ameristar job we take here. A re-roof on a sloped street off Carbon Canyon usually needs grading and drainage review that a same-size job on flat Ameristar service in Chino or Ontario lots never triggers. The city wants to know where the water goes, how the slope holds, and whether the new roof or rooftop equipment platform changes any of that. We handle that review as part of the scope, not as a surprise add-on.
On a hillside re-roof off Carbon Canyon near Los Serranos Country Club, we found Ameristar architectural shingles that had lost tab adhesion along the windward slope after a Santa Ana event. The storm that followed drove water in around the Ameristar furnace flue boot and into the garage-chase air handler below. We tore off to the deck, replaced the compromised underlayment and flashing, installed new architectural shingles and a new flue boot, and re-leveled the Ameristar condenser pad and re-supported its line set. The house has been dry through the last two rain seasons.
That’s the difference between reading about hillside construction and working in it. The right material in the right place. Everything else is just catching up to that decision.
Ameristar Models & Products We Service in Los Serranos
We work on the Ameristar equipment most common in Los Serranos housing stock, which runs 1980s to 2000s tract and semi-custom homes with a share of larger hillside properties. That means Ameristar M4AC and M4AH air-conditioner and air-handler split systems, Ameristar M4RC and M4RH residential split systems and heat pump condensing units, and Ameristar 80% single-stage gas furnaces in the M801P and M951P families, usually in garage and closet chases.
For roofing, we service and re-roof Ameristar architectural shingle and standing seam metal lines. We stock common OEM components for Los Serranos turnaround: coils, control boards, flame sensors, flue boots, and flashing kits. If a part needs ordering, we tell you the timeline before we start, not after.

FAQs – Ameristar Construction in Los Serranos
It’s a Los Serranos problem showing up through Ameristar parts. Canyon-adjacent lots pull wind-blown dust into garage chases, and the dust coats the flame sensor and inducer. The Ameristar 80% furnace design doesn’t fail this way on flatland installs nearly as fast, but any builder-grade furnace in the same chase would struggle. We clean the sensor, seal the chase opening, and usually solve it without a board or inducer replacement. Call (866) 253-8554 and we’ll confirm what’s happening on your lot.
Yes, typically 15 to 30 percent more, because slope access, safety tie-offs, tear-off debris handling, and Chino Hills grading and drainage review all add real labor and time. On flat Chino or Ontario lots, Yorba Linda Ameristar service included, a roof is mostly straightforward square footage. In Los Serranos, the pitch and the city’s review process change the scope. Call (866) 253-8554 for a line-item estimate on your specific roof.
Usually, yes. We re-level the pad, re-support the line set, check the disconnect conduit at the wall, and correct the drainage that caused the settlement. If the line set is kinked badly enough to restrict refrigerant flow, we’ll tell you what replacement costs before recommending it. Call (866) 253-8554 and we’ll assess the pad and line set on site.
Metal makes sense on many hillside lots in Los Serranos because standing seam handles wind uplift and ember exposure better than architectural shingles, but it runs $15,000 to $40,000 and the substrate still needs proper underlayment and flashing. We’ll look at your slope orientation, the existing deck condition, and the Chino Hills grading review before recommending metal versus architectural shingle, or if Ameristar repair in Montclair style flat-lot solutions apply. Call (866) 253-8554 and we’ll give you both numbers side by side.
No. We’re an independent contractor, not authorized, sponsored, or warranty-endorsed by Ameristar. That independence means we quote honest repair-versus-replace numbers rather than steering every call toward a sale. We use OEM Ameristar parts where the unit’s remaining life justifies them, and aftermarket equivalents for commodity items where they don’t. Call (866) 253-8554 if you want a straight read on your Ameristar equipment.
