Lennox HVAC service in Hemet runs $150–$650 for repairs and $3,500–$7,500 for full system replacement, with most calls completed same-day. We’re an independent Lennox service provider — not manufacturer-authorized — with 16 years of hands-on experience across Hemet’s manufactured-home parks and older tract neighborhoods. Call (855) 467-1888 for a free estimate.
Our team services every Lennox product line from Merit to Signature, and we’ve learned how the San Jacinto Valley’s 110°F-plus heat changes what fails and when. We also provide San Jacinto Lennox service with the same field-supervised approach. Jason Trent, our owner and Field Supervisor, still walks job sites himself. That matters when your compressor seizes on a Saturday in July.
Why Hemet Residents Choose Us for Lennox Service
We’ve been working on Lennox equipment in Hemet long enough to recognize the patterns. The Merit 13ACD that labors through August in a 92543 mobile home fails differently than the same unit in a site-built Murrieta tract house. We know because we’ve replaced both.
Our Lennox sales & service approach is built on factory-trained familiarity with nine major brands, not franchise-mandated scripts. Jason Trent grew up in the San Fernando Valley and spent enough summers without reliable AC to understand urgency. He took HVAC coursework at Los Angeles Trade-Technical College before building Stonegate into a 16-year operation with nearly 500 verified reviews. When a Lennox furnace heat exchanger cracks in a 55+ community off Florida Avenue, Jason’s the one checking the combustion analysis himself.
We stock OEM Lennox compressors and heat exchangers for critical failures, plus quality aftermarket capacitors and contactors for faster, cost-effective fixes. Our trucks carry parts for the most common Lennox models in Hemet’s 92543, 92544, 92545, and 92546 zip codes. No waiting two weeks for a coil that we should have on the shelf.
Common Lennox HVAC Problems We Solve in Hemet
- Compressor thermal overload in Merit 13ACD units. Hemet’s basin geography traps heat so effectively that consecutive 110°F days push discharge pressures past design limits. We’ve replaced dozens of seized Merit compressors in 92543 and 92545 manufactured homes after heatwaves that barely register in Temecula.
- Evaporator coil fouling from belly-duct debris. Mobile homes built in the 1970s and 1980s have ductwork running through the crawl space below the floor. Insulation particles and dust get pulled into Lennox coils, choking airflow until the system ices up. Cleaning these coils means working in spaces most techs won’t crawl into.
- Run capacitor failure across all series. Hemet’s older manufactured-home parks have voltage fluctuation issues that shorten capacitor life to 2–3 years. We see this on Signature XPG16 and Merit 14ACX units alike. It’s a cheap fix if caught early, a compressor killer if ignored.
- Heat exchanger micro-cracking in EL180UHNE furnaces. Winter nights in Hemet drop below freezing multiple times per year. Park homes with poor insulation force furnaces into constant cycling. The EL180’s heat exchanger develops cracks from expansion stress, creating carbon monoxide risks that demand immediate shutdown.
- Swamp cooler to refrigerated air upgrades. Many Hemet retirees still run evaporative coolers that stop working above 108°F — not because they’re broken, but because the physics collapses. We regularly convert these setups to Lennox MLA mini-split systems when the homeowner realizes July isn’t getting cooler.
Lennox Service in Hemet: What Local Conditions Mean for Your Equipment
Hemet sits at roughly 1,600 feet in the San Jacinto Valley, surrounded by mountains that block Pacific marine air and turn the basin into a solar oven. Just to the west, we also handle Lennox service in Valle Vista, where the same heat-trapping geography applies. Summer peaks hit 108–112°F while winter nights freeze. This full-spectrum demand is hard on any HVAC system, but Lennox owners in Hemet face an added constraint: the city’s manufactured-home parks, particularly those off 7th Street and Florida Avenue, were built with undersized belly-duct systems and limited equipment access that central-air retrofits simply can’t overcome.
For these homes, Lennox mini-split installations have become our preferred solution. The MLA series doesn’t need ductwork. We mount the condenser on a custom pad, run lineset through a new chase, and deliver zoned cooling to rooms that never had it. Last July, we replaced a Lennox Merit 13ACD in a 1978 mobile home on Warren Road in 92543. The compressor had seized during a 112°F heatwave. We installed a Lennox SL28XCV variable-speed condenser on an elevated pad above flood-prone dirt, re-routing the lineset to bypass collapsed belly ductwork. The homeowner held 75°F through the next spike. The system will tell you what’s wrong — you just have to know how to listen.
Lennox Models & Products We Service in Hemet
We work on the full Lennox residential and light-commercial lineup. The Merit Series 13ACD and 14ACX remain common in Hemet’s 1970s–1990s housing stock. The Signature Series XPG16 and SL28XCV serve homeowners upgrading for efficiency. The EL180UHNE gas furnace heats park homes and tract houses across 92543 and 92545, and we deliver Lennox repair in Homeland with the same parts-stocked trucks. For ductless retrofits in manufactured housing, we install and service Lennox MLA mini-split units.
Our parts strategy is straightforward: OEM Lennox compressors and heat exchangers for components where failure means total system loss, quality aftermarket capacitors and contactors where the specification is standard and the savings matter. We keep common Lennox capacitors, contactors, and defrost boards in stock for same-day Hemet turnaround. For compressor or coil failures in units over 12 years old, we’ll tell you honestly: replacement usually beats repair.
Lennox Service Pricing in Hemet
| Service | Price Range |
|---|---|
| AC Repair | $150–$650 |
| AC Installation | $3,500–$7,500 |
| Furnace Repair | $150–$700 |
| Tune-Up | $80–$200 |
What drives cost? Compressor replacement lands at the high end of AC repair. Full system replacement with duct modification in a manufactured home pushes installation toward the top of the range. A standard tune-up — coil cleaning, refrigerant check, electrical testing, capacitor inspection — stays at the lower end unless we find a developing problem.
Every estimate is free and itemized. No vague “plus materials” language. Call (855) 467-1888 and we’ll give you a real number for your specific Lennox system.

FAQs — Lennox HVAC in Hemet
Repair makes sense if the unit is under 10 years old and the failure is a capacitor, contactor, or minor refrigerant leak. Replace if the compressor has failed and the unit is over 12 years old — the 13ACD’s efficiency rating can’t justify a $1,500+ compressor job in Hemet’s heat load. Call (855) 467-1888 for a free diagnosis and honest recommendation.
Yes. Lennox MLA mini-splits are our preferred retrofit for these homes because they bypass collapsed or undersized belly ductwork entirely. We handle the pad installation, electrical run, and lineset routing. Most Florida Avenue-area installs complete in one day.
Maybe. If your EL180UHNE is cycling on the high-limit switch, blowing cold air, or triggering your CO detector, shut it down and call us. Heat exchanger cracks from Hemet’s freeze-thaw cycles are a documented failure mode in park homes. We test with combustion analyzers and won’t clear a unit that isn’t safe.
Yes. The City of Hemet requires permits for HVAC replacements, including electrical and mechanical inspections. We pull permits on all full-system installations and coordinate inspections so you’re not chasing paperwork. This is standard on our AC installations and Heating & Furnace in Hemet replacements.
No. Breaker trips under thermal load usually mean a failing capacitor, dirty condenser raising head pressure, or a compressor drawing excessive amperage as it dies. In Hemet’s 110°F heat, these problems accelerate fast. Don’t reset the breaker repeatedly — you’ll damage the compressor or create a fire risk. Call (855) 467-1888 for same-day troubleshooting.
