Dalton Heating & Air is the HVAC company Pasadena homeowners call when a system fails during a July heat wave or a January cold snap. Our crews work on the houses that make Pasadena different: century-old Craftsman and Spanish Colonial homes with original ductwork, tight crawl spaces, and preservation rules that most HVAC companies never deal with. We put every price in writing before work starts, guarantee every repair for a full year, and answer the phone with a live person day or night. Call (626) 657-5344 when you need a straight answer and a crew that shows up.
Why Pasadena Homes Are Different
Pasadena’s housing stock forces a kind of precision that newer suburbs don’t demand. A 1915 Craftsman in Bungalow Heaven may have lathe-and-plaster walls, no central air, and a crawl space too shallow for standard duct runs. A Spanish Colonial in San Rafael Hills may have original tile work we need to protect while routing refrigerant lines. None of this is hypothetical for us: it is the daily reality of working in Pasadena.
The climate adds another layer. Summer heat waves regularly push temperatures above 100°F, while winter nights can dip near freezing. That dual demand means a system must cool hard in August and heat reliably in December. When a technician understands both loads and the house itself, the job gets done correctly the first time. Pasadena also has landmark districts like Bungalow Heaven where preservation guidelines require condensers out of sight and slim-duct systems that fit inside original wall cavities. We plan for that before the first bracket goes on the wall.
Styles & brands we work with




Our Main Pasadena Services
Three services carry most of the weight for Pasadena homeowners, so we built a dedicated page for each one. Each page covers local pricing, what the job involves in Pasadena’s housing stock, and how our written guarantee applies.
AC Repair in Pasadena
Pasadena’s older homes often run air conditioners that were retrofitted into structures never designed for them, and when a capacitor, contactor, or refrigerant line fails in August, waiting is not an option. We diagnose the problem, show you the written price before any work begins, and complete the repair inside the same visit whenever the part is in the truck. We service Carrier, Trane, Lennox, Goodman, and five other major brands, and every repair carries a 365-day written guarantee. Full details on AC Repair in Pasadena.

Heat Pump Installation in Pasadena
A heat pump can heat and cool the same Pasadena house, which makes sense when winter nights and summer heat waves both demand reliable output. Many of the homes we retrofit have no existing central air, so we plan the refrigerant line routing, the ductwork or ductless layout, and the condenser placement against preservation rules and lot constraints. You get a fixed written price and a set install date before anything is ordered. Full details on Heat Pump Installation in Pasadena.

Furnace Repair in Pasadena
Pasadena furnaces tend to be smaller, older, and tucked into spaces with poor access, and when one fails on a cold night, the house gets uncomfortable fast. We diagnose the ignition system, heat exchanger, or blower issue and give you a written repair price before we touch a component. If the repair does not hold, we return at no charge within the guarantee period. That is The Garrison Code, and it applies to every job. Full details on Furnace Repair in Pasadena.

Pasadena pushes prices toward the higher end when a home has restricted crawl spaces, preservation requirements, or ductwork that must be replaced rather than reused. What never changes: the price is in writing before we start, and it does not move after you approve it.
