AfterHVAC Company in Tustin, CA
Tustin sits in a part of Orange County where summer temperatures regularly climb past 90 degrees and the marine layer doesn’t always make it inland. That means air conditioning in Tustin gets worked hard from June through October, and the age of the housing stock here, much of it built between the 1950s and 1980s, shows up in the service calls we run. We’re Dalton Heating & Air, and we handle AC repair, heat pump installation, and furnace repair for Tustin homeowners who want a written price before any work starts. If your system is acting up, call (361) 306-9515 and you’ll reach a live person, not a voicemail tree.
Why Tustin Homes Are Different
Tustin’s housing stock splits into two broad groups, and each one changes how we approach an HVAC job. The older neighborhoods like Old Town Tustin and the areas around Tustin High School have homes from the 1940s and 1950s. A lot of those were built before central air was standard, so the ductwork was retrofitted later and we regularly find runs that are undersized for modern equipment. The newer master-planned communities like Tustin Ranch and Columbus Square were built with efficient, larger systems, but those units have now been running for 15 to 25 years and are reaching the age where compressors and heat exchangers start to fail.
Elevation and microclimate matter here too. Homes up by Tustin Ranch and Peters Canyon catch more sun exposure and less of the coastal breeze than properties down near the 5, so the same size house can have a noticeably different cooling load. We size equipment and diagnose airflow with that in mind rather than applying a one-size-fits-all rule. Tustin also has HOA communities where outside condenser placement and noise rules come up, and we’ll flag that before an installation so there are no surprises at the permit stage.
Our Main Tustin Services
Most Tustin homeowners call us for one of three jobs, and each has its own dedicated page with specific pricing, timelines, and what to expect.
AC Repair in Tustin
When an air conditioner goes down in a Tustin August, it doesn’t take long for the upstairs to become uncomfortable. Our AC Repair in Tustin page covers the most common failures we see in the area: capacitor failures on older units, refrigerant leaks on systems that have been topped off too many times, and condensate drain clogs that shut the system down. Every repair gets a written price before we turn a wrench, and it’s covered by a written full-year guarantee.
Heat Pump Installation in Tustin
Heat pumps are a practical fit for Tustin’s climate because they handle both cooling and the mild winter heating we get here without a separate furnace. Our Heat Pump Installation in Tustin page goes into sizing, equipment options, and what a typical installation runs. The job includes a load calculation, written fixed quote, and coordination with any HOA requirements on condenser placement.
Furnace Repair in Tustin
Furnaces in Tustin don’t see the run time that systems in colder climates do, but when a cold snap hits, a furnace that has sat idle for months tends to show its age. Our Furnace Repair in Tustin page covers ignition failures, blower motor issues, and heat exchanger concerns on systems that are often 15 to 25 years old. Repairs are priced in writing before work starts and guaranteed for a year. If the fix doesn’t hold, we return at no charge.

Brands We Service in Tustin
Our technicians are factory-trained on most major residential brands you’ll find in Tustin homes, including Rheem, York, Daikin, and Bryant.

We carry common replacement parts on the truck, which keeps most repairs to a single visit. See our brands for the full list.
Pricing for HVAC Company in Tustin, CA
| Service | Typical range in Tustin |

Repair prices in Tustin move toward the higher end when the job involves a refrigerant leak, an undersized duct correction, or a unit located in a tight attic or a Tustin Ranch hillside lot that makes access harder. Installation cost depends on the home’s square footage, efficiency rating, and whether new ductwork or an electrical upgrade is needed. Whatever the number, it’s in writing before any work begins, and that price doesn’t change when the job gets harder than expected.
