AfterHVAC Company in Pasadena, CA
Dalton Heating & Air handles HVAC work across Pasadena, where 1920s Spanish Colonials sit next to mid-century ranches and newer hillside builds. That mix means compressors bolted to flat roofs, furnaces squeezed into crawlspaces, and ductwork routed through plaster walls nobody wants opened up. We work on all of it. When your AC dies in August or your furnace quits in January, call (361) 306-9515 and a real person answers, day or night.
Why Pasadena Homes Are Different
Pasadena’s housing stock runs older than most of Los Angeles County. Walk streets like Bungalow Heaven or Madison Heights and you’re looking at 1920s and 1930s construction, where original gravity furnaces were later retrofitted with forced-air systems and central AC. That retrofit history matters. We routinely find undersized return ducts, asbestos-wrapped plenums that need encapsulation before any work can start, and electrical panels that were never upgraded to carry a modern heat pump’s amp draw. The hills above the Rose Bowl add another layer: homes on Linda Vista and Annandale sit on slopes where condenser pads settle and tilt, which shortens compressor life. In the flats near Lamanda Park and Villa Parke, we see more issues with corrosion from sprinkler overspray hitting condenser coils. Not one of these is a dealbreaker, but they all change how a job should be scoped. A company that prices from a spreadsheet without looking at the house will miss half of it.
Climate is the other constant. Pasadena regularly clears 95°F in July and August, and the overnight lows in December dip into the 40s. Systems here get worked hard on both ends of the calendar. Homes in the San Rafael Hills and Hastings Ranch areas deal with stronger sun exposure and, in some streets, Santa Ana wind that pushes dust into condenser fins. That’s a maintenance reality, not an emergency, but it means annual tune-ups earn their keep faster here than in coastal ZIP codes.
Our Main Pasadena Services
Most calls we take in Pasadena are for one of two things: an air conditioner that stopped cooling in the middle of a heat wave, or a furnace acting up once the nights turn cold. Below is how each job works here, with links to the full Pasadena pages.
AC Repair in Pasadena
Pasadena AC repair calls peak between June and September, and the specific failures track with the housing stock. Older condensers on hillside lots fail on capacitors and contactors more often, while systems in tightly packed neighborhoods like Bungalow Heaven tend to struggle with airflow restrictions from undersized returns. Before any repair starts, you get a written price. If the repair doesn’t hold, the guarantee is in writing for a full year and we return at no charge. Full breakdown on the AC Repair in Pasadena page.
Heat Pump Installation in Pasadena
A heat pump handles both cooling and heating, which fits Pasadena’s climate well. The winter is mild enough that a properly sized heat pump covers the heating load without backup strips in most homes. Installation here often involves panel work, since many older Pasadena homes need a dedicated circuit added before the outdoor unit goes in. Load calculations, permitting, and HOA approvals in condos are all part of the job. Details, pricing, and what to expect are on the Heat Pump Installation in Pasadena page.
Furnace Repair in Pasadena
Furnace calls in Pasadena spike in December and January, when overnight temperatures first drop into the 40s. The typical failures we see are ignition problems on older gas furnaces, blower motors wearing out, and limit switches tripping from restricted airflow. Furnaces in crawlspaces, common in the Linda Vista and Annandale hills, also deal with more rust from trapped moisture. Every furnace repair carries a one-year written guarantee. If the work fails, the second visit is free. See the Furnace Repair in Pasadena page for repair ranges and what’s covered.

In Pasadena, we work on a lot of Rheem and York systems in older homes, plus Daikin and Bryant units in newer installations and heat pump retrofits across the San Rafael Hills.

Pricing for HVAC Company in Pasadena, CA
| Service | Typical Range in Pasadena |
|---|---|
| AC Repair | $150 – $650 |
| Furnace Repair | $150 – $700 |
| AC Installation | $3,500 – $7,500 |
| Tune-Up | $80 – $200 |
Pasadena pricing runs slightly above the LA County average on installations, mostly because older homes here need extra electrical work, duct modifications, or panel upgrades before the new equipment goes in. Whatever the number ends up being, you’ll see it in writing before any work starts. That’s The Garrison Standard, and we don’t make exceptions.
