Lennox HVAC in Highland, CA | Crestview Heating & Air California
We provide independent Lennox service throughout Highland, CA, with 19 years of hands-on experience diagnosing how Lennox systems perform in this mountain-edge microclimate, and we also offer San Bernardino Lennox service to nearby communities. What sets our work apart is the air quality reality here: Highland’s position at the San Bernardino Mountains’ alluvial fan base traps wildfire smoke and Inland Empire smog against the mountain face, making whole-house air scrubbers and high-MERV filtration standard equipment on every Lennox install we do, not an optional upsell.

Why Highland Residents Choose Us for Lennox Service
We’ve been working on Lennox equipment in Highland long enough to know the difference between a generic diagnosis and one that accounts for this city’s specific problems. Marcus Feldman, our owner and Service Manager, still runs service calls himself. He grew up in Woodland Hills watching summer heat wreck systems that weren’t built for it, trained in HVAC/R at Los Angeles Trade-Technical College, and spent the next two decades learning how Lennox variable-speed blowers behave when attic ducts hit 145°F.
That matters because Highland’s housing stock, mostly 1960s–1980s tract homes built before cityhood in 1987, forces your Lennox system to fight through ductwork routed through unconditioned attics. We’ve replaced blower motors on EL18XCV units where the original mastic seal failed from thermal cycling, and we’ve cleaned condenser coils packed with cottonwood after Santa Ana winds barreled through the Cajon Pass, similar to the Lennox service in Muscoy we provide. We carry OEM Lennox parts for critical components, and we stock compatible aftermarket capacitors and contactors so you’re not waiting on a backorder when it’s 108°F outside.
Our Lennox sales & service covers every model line from Merit to Dave Lennox Signature Collection. We’re not a franchise dispatch center. When you call, you’re talking to someone who knows why your specific Lennox problem keeps happening in Highland specifically.
Common Lennox HVAC Problems We Solve in Highland
- High-pressure cutouts on Merit 14ACX condensers. Santa Ana winds funnel debris through the Cajon Pass and mountain gap directly across Highland’s north-facing neighborhoods. Cottonwood, pine needles, and dry chaparral dust pack into condenser coils faster here than in flatland cities. We clean the coil, check refrigerant charge, and recommend a post-Santa-Ana cleaning each autumn.
- Variable-speed blower motor overcurrent faults on Elite EL18XCV units. Original duct mastic in Highland’s 1970s tract homes degrades in attics that reach 140–150°F. Return air leaks force the blower to work harder, drawing overcurrent and throwing fault codes. We seal returns properly, then verify amp draw against Lennox spec.
- TXV failure on R-22 Merit systems. Highland’s summer highs exceed 105°F while the mountain backdrop blocks prevailing winds from flushing heat out. That extended runtime cycles TXVs through wider thermal swings than coastal Inland Empire cities. We’ve replaced dozens on aging Merit units still running R-22.
- Condensate drain pan corrosion. Winter nights here drop below freezing more reliably than the valley floor. Freeze-thaw cycles in unconditioned attics crack plastic pans and corrode metal ones. We inspect drainage paths on every fall tune-up because a blocked drain in January means water damage, not just poor cooling.
- Heat pump underperformance on hillside installations. Newer Highland subdivisions along mountain-facing slopes have steeper rooflines and tighter utility chases. Heat pumps sized only for cooling load underperform on genuine freeze nights here. We verify heating balance points against actual local design temperatures, not generic San Bernardino County data.
Lennox Service in Highland: What Local Conditions Mean for Your Equipment
Last July, we serviced a 15-year-old Lennox Elite system on Balsam Avenue in the 1970s tract home section of Highland. The outdoor condenser had a high-pressure cutout from cottonwood debris caught during a Santa Ana wind event. We cleaned the coil, replaced the capacitor, and recommended a post-Santa-Ana coil cleaning service to prevent recurrence.
That call was typical for reasons generic Lennox pages miss. Highland sits at roughly 1,200–1,500 feet elevation in a temperature inversion bowl that traps wildfire smoke, particulate matter, and Inland Empire smog directly against the San Bernardino Mountains. The EPA routinely records among the worst air quality readings in the entire US here. For Lennox owners, that means your filtration system works harder than a comparable unit in Fontana, Riverside, or even one receiving Redlands Lennox service ever would. When we install a Lennox system in Highland, whole-house air scrubbers and high-MERV filtration aren’t premium add-ons. They’re baseline equipment. We’ve seen Signature Series variable-speed systems run their indoor air quality accessories nearly year-round here, where in other cities they’d cycle off for months. That usage pattern affects filter change intervals, blower motor wear, and whether a 14 SEER Merit unit can actually deliver its rated efficiency with a standard 1-inch filter slot.
Lennox Models & Products We Service in Highland
We work on every Lennox residential line, from entry-level Merit through the Dave Lennox Signature Collection.
- Merit Series: 14ACX, 14HPX, and legacy R-22 units still running in Highland’s older tracts. We stock replacement capacitors and contactors for fast turnaround, and we source OEM compressors when the math favors repair over replacement.
- Elite Series: EL18XCV variable-speed AC, EL296E two-stage furnace. These are common in 1990s–2000s Highland homes. We carry OEM circuit boards and blower motors, and we know the specific fault codes these units throw in high-static duct systems.
- Signature Series / Dave Lennox Signature Collection: SL28XCV, SLP98V, and full modulating systems. We handle warranty-adjacent work and precision commissioning for these, including airflow verification in Highland’s restrictive attic spaces.
Our parts approach is straightforward. Critical components, compressors, circuit boards, and TXVs get OEM Lennox parts. For capacitors, contactors, and hard-start kits, we’ll recommend quality aftermarket if OEM backorders would leave you sweating through a 110°F weekend. If I wouldn’t put it in my own house, I’m not putting it in yours.

FAQs — Lennox HVAC in Highland
Your compressor is working against a dirty condenser, low refrigerant charge, or failing capacitor, all of which spike amp draw when ambient temperatures exceed 105°F. Highland’s extended cooling season and Santa Ana debris loads accelerate these failures. We measure actual amp draw against Lennox spec and clean coils before recommending any parts. Call (844) 560-6978 if your breaker tripped more than once, it’s not a fluke.
Usually not, if the compressor or TXV has failed. R-22 refrigerant is prohibitively expensive, and Highland’s 105°F+ summers force aging systems to run at maximum load for months. We assess remaining system life against replacement cost, factoring in whether your current ductwork can support a modern variable-speed unit. Call (844) 560-6978 for a free replacement estimate.
Every 30–45 days during peak heating and cooling seasons, and every 60 days shoulder season. Highland’s trapped particulate matter loads filters faster than most Inland Empire cities. If you’re running a Lennox whole-house air scrubber, we check those media during tune-ups and replace on condition, not calendar.
Yes, San Bernardino County requires permits for full system replacements, and Highland’s cityhood since 1987 means local inspection coordination, just as we handle for customers needing Lennox repair in Loma Linda. We handle permit paperwork as part of our installation service, including Title 24 compliance documentation for the county.
Probably smaller than you think. Original 1960s–1980s tract homes in Highland often have 3–4 ton systems that were oversized to compensate for leaky ducts. We perform Manual J load calculations and duct blaster testing to right-size your replacement, sometimes dropping a half-ton after sealing returns. Proper sizing matters more in Highland’s climate extremes than brute-force capacity.
