Halden Heating & Air is the HVAC company for Westmont, CA, built around a simple promise: a written price before any work starts, a live arrival time you can track, and a real person on the phone 24/7. Westmont’s housing stock – mostly mid-century single-family homes with aging ductwork and minimal insulation – makes heating and cooling work here different from the coastal neighborhoods. Older systems, tighter budgets, and inland heat all shape how we approach every job. Call (424) 358-3791 when your AC quits or your furnace acts up; someone answers.
Why Westmont Homes Are Different
Westmont is dense with single-family homes built between the 1940s and 1970s, and a lot of them still run on their original ductwork. That means leaky ducts, uneven cooling, and energy bills that don’t match the square footage. Many homes in Westmont also have minimal insulation – some with none in the attic – so the AC works harder than it should during summer. The inland location pushes temperatures higher than the coast, and heavy summer use exposes weak systems fast. We also see a pattern here we don’t see as often elsewhere: original asbestos-wrapped ducts that are now deteriorating, quietly hurting indoor air quality and system efficiency. When a Westmont homeowner tells us one bedroom stays hot while the living room freezes, the ducts are usually the first place we look.
Styles & brands we work with
Our Main Westmont Services
Westmont homeowners call us most for two things: an AC that stopped cooling on a hot afternoon, and a furnace that won’t start on the first cold night. Here’s what each job looks like in Westmont.
AC Repair in Westmont
Westmont’s summer heat is hard on air conditioning, and older systems often fail during the worst stretch. Our AC repair work in Westmont usually involves diagnosing refrigerant problems (the coolant that produces cold air), failing capacitors (the electrical part that starts the compressor), clogged condenser coils, or duct leaks. Because many Westmont homes run their AC heavily from June through September, parts wear faster here than in coastal LA. We arrive with a written price and common parts on the truck.

AC Installation in Westmont
Replacing an AC system in Westmont means dealing with older electrical panels, tight attic access, and ducts that may need sealing before a new unit can do its job. We don’t pad the quote with work you don’t need; we show you what the system actually requires, in writing, before anything is ordered. For Westmont homes from the 1940s through 1970s, the right install is a fixed price, a set install date, and a system sized for how hot Westmont actually gets. AC Installation in Westmont
Furnace Repair in Westmont
Westmont winters are mild, but when that first cold snap hits, a furnace that won’t ignite becomes an urgent problem. Furnace repair in Westmont usually comes down to failed igniters, dirty flame sensors, or a cracked heat exchanger on older units – and that last one is a safety issue, not just a comfort one. If your furnace is making a smell or short-cycling, don’t keep resetting it. We diagnose it, hand you a written price, and fix it the same day in most cases. Furnace Repair in Westmont
