Dalton Heating & Air handles the heat, humidity, and older-home quirks that define San Gabriel. Much of the housing stock here was built between the 1920s and 1960s, which means our technicians routinely work around vintage plaster walls, undersized electrical panels, and crawl spaces that haven’t been touched in fifty years. We put every price in writing before work begins, guarantee every repair for a full year, and answer the phone with a live person around the clock. Call (626) 657-5344 when your system stops cooperating.
Why San Gabriel Homes Are Different
San Gabriel sits far enough inland that summer temperatures regularly outpace the coast by ten degrees or more. Heat waves here are not a coastal rumor; they’re a July routine, and that puts real strain on aging condensers. The housing stock adds another layer. Pre-war bungalows near the San Gabriel Mission often have original plaster walls and minimal insulation, which changes how we approach everything from duct sizing to thermostat placement. Mid-century ranch homes, common north of Las Tunas Drive, tend to have crawl spaces and attics that work well for ductwork but frequently lack the electrical capacity that a modern heat pump demands.
In the historic districts, we see this pattern constantly: homeowners want central air but won’t sacrifice vintage lath-and-plaster walls to get it. Ductless mini-split systems solve that problem without tearing into original finishes. Elsewhere, homes built before panel upgrades became standard may need a subpanel or service upgrade before a new system can be installed safely. We’ll tell you that on the first visit, not after the drywall is open.
Styles & brands we work with
Our Main San Gabriel Services
Most calls to our San Gabriel dispatch fall into two buckets: repairs on systems that quit mid-heat-wave, and installations that bring older homes up to modern cooling standards without gutting the architecture.
AC Repair in San Gabriel
When a San Gabriel home loses cooling in August, the clock matters. Our technicians arrive with parts for major brands on the truck, so the most common fixes happen same-day. We diagnose first, put the repair price in writing, and then do the work. Every repair carries our one-year written guarantee, and if it fails inside that window, we return free of charge. For details on what we fix and what it costs, see AC Repair in San Gabriel.
Heat Pump Installation in San Gabriel
Heat pumps make particular sense in San Gabriel, where mild winters mean one system can handle both cooling and the occasional chilly night. For older homes without ductwork, ductless mini-splits preserve original plaster and trim while delivering the comfort central air would. We handle the load calculation, the electrical assessment, and the full installation, with a written price before any equipment is ordered. See Heat Pump Installation in San Gabriel for pricing and process.
Furnace Repair in San Gabriel
San Gabriel winters are mild, but a dead furnace on a forty-degree night is still a real problem, especially in homes that rely on older gas furnaces. We service and repair those systems, from pilot assemblies to blower motors, and the repair is guaranteed in writing for a full year. Most furnace repairs run $150 – $450 depending on the part.

What pushes a repair toward the high end in San Gabriel is usually access. Crawl-space furnaces and attic air handlers add labor time, and homes with outdated panels sometimes need an electrical upgrade before a new system can pass inspection. Whatever the job, the price is in writing before any work starts, and nothing gets added at the end.
