AfterHVAC Company in San Carlos, CA
Dalton Heating & Air is the HVAC company San Carlos homeowners call when a system fails and the answer needs to be straight, fast, and in writing. Most San Carlos homes were built between the 1950s and 1980s, which means furnaces and air conditioners are hitting the age where repairs stop making sense and replacement becomes the real conversation. Whether it’s a dead compressor in July or a furnace that won’t fire in December, we give you a written price before any work starts and back every repair with a 365-day guarantee. Call (361) 306-9515 and you’ll reach a live person, any hour.
Why San Carlos Homes Are Different
San Carlos sits on a slope between the bay and the Santa Cruz Mountains, and that terrain changes how HVAC systems wear. Homes in the flats near El Camino Real deal with bay moisture and mild marine air, while houses up the hill at the foot of Crestview Drive or Brittan Avenue get hotter afternoon sun and colder nights. A furnace cycling short because the return air is choked, or an AC condenser struggling against direct afternoon exposure on a hillside lot, are both common calls here.
The housing stock is heavily single-family, mostly ranchers and two-story builds from the 50s through the 80s. That means original ductwork is often undersized for modern heat pump output, and older electrical panels may not have the headroom a new system requires. We also work around San Carlos’s permitting process with the city’s building department, and HOAs in the hills sometimes require equipment placement that doesn’t block a sightline or sit too close to a property line. None of that surprises us. It just changes the order of the job.
Our Main San Carlos Services
Three things dominate the HVAC calls in San Carlos: AC systems that quit in summer, heat pumps going in as replacements for old gas furnaces, and furnaces that fail when the temperature drops. Each service has its own detailed page.
AC Repair in San Carlos
When a San Carlos AC system fails, it’s rarely a simple part swap. Hillside condenser pads shift over time, which stresses the refrigerant lines running into the house. Older ductwork in 70s-era ranchers can also leak enough airflow to freeze an evaporator coil. Our techs diagnose the entire path, not just the box outside. We stock common capacitors, contactors, and fan motors on the truck so we can usually get a system cooling the same day it’s diagnosed. Every repair gets a written quote before work starts and a written one-year guarantee after. Read more on our AC Repair in San Carlos page.
Heat Pump Installation in San Carlos
Heat pumps are becoming the default replacement in San Carlos, partly because the climate suits them and partly because gas rates keep climbing. The installation itself is more involved here than in flat cities: exterior pad leveling on slopes, line-set runs through crawl spaces or finished walls, and electrical service upgrades where the panel is original to the house. We size the system with a load calculation, not a rule of thumb, and the price is written before we order equipment. See what a full install covers on our Heat Pump Installation in San Carlos page.
Furnace Repair in San Carlos
San Carlos nights get cold enough that a furnace failure is urgent, not inconvenient. The typical call early in the season is an ignition problem: a dirty flame sensor, a failing igniter, or a pressure switch that won’t close because a flue is partially blocked. In older homes, cracked heat exchangers show up more often than homeowners expect because the furnaces are simply at end of life. We test for combustion safety on every repair and give you the written price before the work begins. Details are on the Furnace Repair in San Carlos page.

Brands We Service in San Carlos
We’re factory-trained on nine major residential HVAC brands, and in San Carlos that matters because the installed base is mixed. We see a lot of Goodman and Rheem in the older tract homes, York and Daikin in more recent remodels and additions. We keep common parts in local van stock, which shortens repair time on most calls. See the full list on our brands page.

FAQs About HVAC Company in San Carlos
Most San Carlos repair calls are handled same-day. Emergency dispatches, like a furnace down on a cold night or an AC failure during a heat spike, are prioritized. Call (361) 306-9515 and a live person will give you the next available window, not a callback line.
Most new installations, including heat pumps and full AC replacements, do require a permit from the City of San Carlos building department. We handle the permit application and scheduling as part of the installation. Simple repairs and tune-ups don’t need one.
Yes. Some hillside HOAs restrict condenser placement, noise output, or visibility from the street. We review the HOA documents before quoting equipment location, so the written price reflects the actual installation conditions from day one.
