HVAC Company in Crestline, CA
Dalton Heating & Air is the HVAC company Crestline homeowners call when a furnace quits on a 28-degree night or an AC unit gives out during a September heat spike. Most homes here sit between 4,500 and 6,000 feet, so systems work harder and fail faster than they do down the hill. We show up inside the window, put the price in writing before any work starts, and stand behind every repair with a full-year written guarantee. Call (361) 306-9515 and a live person answers, 24/7.
Why Crestline Homes Are Different
Crestline is not San Bernardino with trees. A cabin off Waters Drive built in the 1950s has different ductwork, different insulation, and different failure points than a newer house near Lake Gregory. We see it in the service calls that come in every season.
The elevation is the biggest variable. At 5,000 feet, air is thinner and moves less heat. A system sized for the valley will short-cycle and overwork up here. Cold snaps in January routinely push furnaces past their limits, and the ones that fail are usually the ones that were never right-sized for mountain duty. Summer brings the opposite problem: afternoons in the 90s with no coastal breeze, and AC units that sat idle for nine months now have to carry the load.
Snow loads matter too. Condenser units buried in snowdrifts can choke airflow, and a vent pipe plastered with ice will trip a furnace limit switch. Then there’s the road time. Crestline sits off Highway 138 and Lake Gregory Drive, and from Riverside-San Bernardino where our dispatch runs, the run up the mountain adds 40 to 50 minutes. We plan for that so you’re not waiting on a tech who underestimated the climb.
Homes here are a mix of 70-year-old cabins, 1980s ranches, and the odd modern build near Crest Forest Drive. Each one needs a different approach. We don’t sell cookie-cutter fixes up here.
Our Main Crestline Services
Three jobs dominate the work we do in Crestline. Each one has its own page with full pricing and detail, but here’s the fast version.
AC Repair in Crestline
When the temperature climbs in July and an AC unit has been sitting since October, the call is usually the same: it runs but doesn’t cool, or it won’t turn on at all. We diagnose the system, explain the fix in plain terms, and hand you a written price before touching a wrench. Most Crestline AC repairs run $150 to $650 depending on the part. Warm air blowing is often low refrigerant; a dead unit is frequently a capacitor or contactor. AC Repair in Crestline has the full breakdown.

Heat Pump Installation in Crestline
A heat pump is a sensible answer for mountain homes because it heats and cools in one unit, and modern cold-climate models hold their output down into the teens. Installation in Crestline means careful sizing for elevation, a proper snow stand for the outdoor unit, and often new electrical work. We handle the full job: load calculation, equipment order, install, and all permits. Typical installs run $3,500 to $7,500. See Heat Pump Installation in Crestline for the details.

Furnace Repair in Crestline
Winter in Crestline is when furnaces earn their keep, and when one fails it fails hard. No heat at 5,000 feet is a real problem, not an inconvenience, so we treat furnace calls as priority work. Common fixes include igniters, flame sensors, limit switches, and control boards, with most repairs landing between $150 and $700. Every repair carries the written full-year guarantee. The full scope is on Furnace Repair in Crestline.

Brands We Service in Crestline
We’re factory-trained on all nine major residential brands. In Crestline that matters because the housing stock is older and the equipment turnover is higher. Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For the mountain inventory, we keep common Goodman, Rheem, and York parts stocked locally, which trims a day off the average parts wait compared to ordering from the valley. See our brands for the full lineup.
Pricing for HVAC Company in Crestline, CA
| Service | Typical range in Crestline |
|---|---|
| AC Repair | $150 – $650 |
| Furnace Repair | $150 – $700 |
| AC Installation | $3,500 – $7,500 |
| Tune-Up | $80 – $200 |
Two things push Crestline prices toward the upper end of those ranges. First, the drive: dispatch from the Inland Empire office adds travel time to every call. Second, deferred maintenance. A unit that hasn’t been touched in five years usually needs more than one fix. Whatever the number is, you get it in writing before work begins. That’s the Garrison Standard, and it’s not optional on any Dalton job.
Neighborhoods We Serve in Crestline
We run service across the whole Crestline footprint, from the lake side out to the forest edge. Most calls route to one of these areas:
- Lake Gregory shoreline
- Cedar Pines Park
- Valley of Enchantment
- Top Town and Crest Forest Drive corridor
- Waters Drive and Old Mill Road area
For urgent calls, like a furnace down in a hard freeze, we aim to have a tech heading up the hill within the hour.

FAQs About HVAC Company in Crestline
Most Crestline calls are answered by a tech on the road within the hour. We stage our schedule knowing the run up Highway 138 takes time, so a dispatch inside 60 minutes is normal, not a stretch goal. Call and you’ll talk to a live person, not a queue.
Most equipment replacements do. San Bernardino County requires permits for new furnace and AC installs, and we pull them as part of the job. Repairs and tune-ups generally don’t need one. We handle the paperwork so you don’t have to chase the county.
We cover the full Crestline area: lake side, forest side, Cedar Pines Park, Valley of Enchantment, and everything in between. The only thing that changes is road time, and we factor that into scheduling, not into the price.
