HVAC Company in Los Alamitos, CA
HVAC work in Los Alamitos comes down to two things: older coastal homes with aging ductwork and the salt air that shortens a condenser’s life. Most repair calls here are either a capacitor that failed on a 15-plus-year-old system or a furnace heat exchanger corroded by years of marine-layer moisture. We’re Dalton Heating & Air, a Garrison Partners company founded in 2003. Every job starts with a written price, and every repair carries a written guarantee for a full year. Call (361) 306-9515 and a live person answers, day or night.
Why Los Alamitos Homes Are Different
Los Alamitos sits in the Los Angeles Basin’s coastal plain, about 6 miles from the ocean. That means a marine layer that rolls in most evenings from spring through early fall, keeping mornings damp well into July. For HVAC equipment, that moisture is the enemy. Condenser coils corrode faster here than they do 15 miles inland. The housing stock runs from 1950s and 1960s ranch homes north of Katella to newer builds in the Rossmoor-adjacent neighborhoods and around Los Alamitos Boulevard. The older homes often still have original duct runs sized for a furnace-only system, which makes adding an AC or converting to a heat pump a real engineering job, not a swap. Many Los Alamitos properties also sit on postage-stamp lots with tight side yards. That changes how we route refrigerant lines and where a condenser can physically sit to meet code clearance. If you’re in a neighborhood with an HOA, the unit placement and noise rating both have to clear board review before we pull the permit.
Our Main Los Alamitos Services
AC repair and furnace repair are the two calls Los Alamitos homeowners make most often, and heat pump installation is growing as the rebates get stronger. Each service has its own Los Alamitos page with pricing and a full breakdown.
AC Repair in Los Alamitos
An AC breakdown in Los Alamitos usually hits in August, when the marine layer thins and the inland heat pushes into the 90s. The most common failures we see are capacitors, contactors, failed condenser fan motors, and low refrigerant from a slow leak in the coil. Before we open the unit, you get the repair price in writing. If it’s done, it’s guaranteed in writing for a year. AC Repair in Los Alamitos

Heat Pump Installation in Los Alamitos
Heat pumps make strong sense in Los Alamitos’s mild winters: you get heating and cooling from one unit, and you’re not paying for gas. The catch is that older Los Alamitos homes typically need a duct assessment and often an electrical panel allowance. We size the system with a Manual J load calculation. Every heat pump install gets a written fixed price before any equipment is ordered. Heat Pump Installation in Los Alamitos

Furnace Repair in Los Alamitos
When the furnace fails in a Los Alamitos winter, it’s often the igniter, flame sensor, or a control board shorted by moisture. Many of these furnaces are original to 1960s and 1970s homes, so the heat exchanger gets a hard look on every visit. Same discipline applies: a written repair price before work starts, and a full-year written guarantee after. Furnace Repair in Los Alamitos
