Lennox HVAC in Hollister, CA | Stonegate Heating & Air California
We provide independent Lennox service across Hollister’s 95023 and 95024 ZIP codes, with same-day availability for most calls. The one thing that makes our Lennox work here different: we’ve learned to read what the Calaveras Fault creep does to outdoor pads and gas connectors, and we factor that into every repair and replacement we quote. For a free estimate on your Lennox system, call us at (855) 467-1888.
Why Hollister Residents Choose Us for Lennox Service
We’ve been working on Lennox equipment in California for 16 years, and in Hollister specifically long enough to know that a tech trained in Salinas or Gilroy will miss things here. The fault creep. The valley heat that hits 105°F while the coast stays mild. The 1960s ranch homes on Park Hill Drive with ductwork never designed for the cooling loads we see now.
Jason Trent, our owner and Field Supervisor, grew up in the San Fernando Valley and spent enough summers without reliable AC to know exactly what that feels like. He took HVAC coursework at Los Angeles Trade-Technical College before building Stonegate into what it is now: nearly 500 reviews at 4.7 stars, with Jason still showing up on the bigger jobs himself because he doesn’t trust a final walkthrough to anyone else. We’re certified on nine major brands, Lennox included, so we never hit you with “we don’t service that model.” We stock common Lennox-specific parts locally to cut wait times, and we use OEM components on critical repairs to keep your warranty intact. Lennox sales & service is one of our core competencies, but we remain an independent provider, not a factory-authorized dealer.
Common Lennox HVAC Problems We Solve in Hollister
- Evaporator coil micro-leaks from thermal cycling. Hollister’s daily temperature swings, 105°F afternoons dropping to the 50s at night, expand and contract refrigerant joints constantly. On older Lennox systems still running R-22, this stress accelerates pinhole leaks at the coil. We pressure-test, locate the leak, and replace with R-410A-compatible coils when the repair makes sense.
- Variable-speed blower motor failures from agricultural dust. The San Benito Valley’s farming activity generates fine particulate that standard 1-inch filters don’t catch. Lennox Elite and Signature series variable-speed motors are precise, but that precision means dust buildup on the control electronics causes premature failure. We clean the module and recommend upgraded filtration.
- Heat exchanger cracking in Merit series furnaces. Hollister winter nights hit the low 30s with frost, then daytime recovery runs the furnace hard. Older Merit 80% furnaces, common in those 2000s tract homes, develop stress cracks in the heat exchanger from this cycling. We inspect with cameras and won’t clear a cracked unit, period.
- Condenser fan motor and capacitor failures from extreme heat plus ground movement. 105°F ambient temperatures already push capacitors to their rating. Add the Calaveras Fault’s slow creep straining electrical connections at the disconnect, and you get intermittent voltage drops that cook motors. We check the pad level and connection integrity, not just the part that failed.
- Refrigerant leaks from shifted condenser pads. We replaced a Lennox Merit 13ACD condenser on Park Hill Drive after the homeowner noticed the unit was starting to tilt. The concrete pad had shifted 2 inches out of level due to fault creep, stressing the copper lineset and causing a slow refrigerant leak. We installed a reinforced pad with deeper footings and upgraded to an EL16XC1 with flexible connectors that can tolerate ongoing movement.
Lennox Service in Hollister: What Local Conditions Mean for Your Equipment
Hollister sits on one of the few continuously creeping faults in the United States. The Calaveras Fault offsets curbs and driveways by inches annually, and that movement doesn’t stop at your property line. For Lennox owners, this means our technicians must inspect flexible gas connectors and refrigerant lines for stress fractures caused by slow ground movement, a failure mode virtually unseen in cities without active fault creep. A furnace replacement on the older ranch-style homes near downtown, where original ductwork was sized for heating only, requires us to verify seismic gas shutoff valve compliance, not as a formality but because the city has seen enough fault-related incidents to enforce it. Meanwhile, Hollister’s inland valley position, far enough from the coast that Pacheco Pass only partially moderates temperatures, produces seasonal swings that coastal-trained techs underestimate. Your Lennox SL28XCV variable-capacity system was engineered for precision, but precision equipment performs poorly when installed on a tilting pad or connected through rigid gas line in ground that moves. We account for both problems before we quote the repair.
Lennox Models & Products We Service in Hollister
We work on the full Lennox residential and light-commercial lineup: the Merit Series (13ACD, 13HPX) still common in those early-2000s Hollister tract builds; the Elite Series (EL16XC1, EL18XCV) that offers a practical efficiency upgrade for homeowners replacing R-22 systems; the Signature Series (SL28XCV, SLP98V) for maximum efficiency in homes with properly sized ductwork; and the Dave Lennox Signature Collection for premium installations. For critical components, heat exchangers, compressors, and control boards, we source OEM Lennox parts to protect your warranty and ensure exact fit. Capacitors and contactors may be quality aftermarket equivalents when OEM stock is back-ordered, but we disclose the substitution and explain why. Our Hollister warehouse stocks common Lennox capacitors, contactors, and blower motors for same-day turnaround on most standard repairs.

Lennox Service Pricing in Hollister
| Service | Price Range in Hollister |
|---|---|
| AC Repair | $150–$650 |
| Furnace Repair | $150–$700 |
| AC Installation | $3,500–$7,500 |
| Tune-Up | $80–$200 |
What drives cost: the part required, refrigerant type and charge amount, accessibility of the indoor coil or furnace, and whether fault-creep damage has affected connected components beyond the failed part. A compressor replacement on a Merit 13ACD runs higher if the pad has shifted and we need to re-pour with deeper footings. Our free estimate includes full diagnostic time, a written quote with line-item breakdown, and an honest assessment of repair versus replacement. If your Lennox system is over 15 years old and the repair exceeds 50% of replacement cost, we’ll tell you. For an exact quote on your system, call (855) 467-1888, estimates are free.

FAQs — Lennox HVAC in Hollister
Yes, California code requires seismic gas shutoff valves in fault-impacted zones, and Hollister’s active Calaveras Fault creep puts the city squarely in that category. We verify existing valve function on every furnace replacement and install new ones where missing or non-compliant. Call (855) 467-1888 to schedule an inspection of your current setup.
The original ductwork in Hollister’s 1950s–1970s ranch stock was sized for heating, not for the cooling loads created by 95–105°F valley afternoons. Your Lennox unit may be perfectly functional while undersized ducts choke airflow. We measure static pressure and airflow at each register to determine whether duct modification or equipment upsizing is the right fix.
Twice yearly, minimum, once before peak summer and again after harvest season. The fine dust from San Benito Valley agriculture coats condenser fins, raising head pressure and forcing your compressor to work harder. For homes near active fields, we sometimes recommend quarterly coil cleaning during the dustiest months.
Sometimes, but not always. Modern R-410A and R-32 systems operate at different pressures and often require larger line sets. If your Hollister home has the original ductwork from the 1960s or the tight duct runs common in 2000s tract builds, we test airflow before quoting to avoid installing a unit that can’t breathe properly. Call (855) 467-1888 for a free assessment.
The EL18XCV or SL28XCV variable-capacity systems handle Hollister’s wide swing most efficiently, modulating output rather than cycling full-on or full-off. That said, the best model is the one properly matched to your ductwork and load calculation. We run Manual J calculations on every replacement, not rule-of-thumb sizing. Call (855) 467-1888 to schedule a load analysis.
