HVAC Company in La Puente, CA
Dalton Heating & Air is the HVAC company La Puente homeowners call when a system fails and they want it handled by the book. La Puente’s mix of 1950s and 1960s ranch homes, tight lots, and San Gabriel Valley summer heat means most of our work here involves older ductwork, undersized electrical panels, and AC systems working harder than they were ever designed to. You can reach a live person at (361) 306-9515 any hour, any day.
Why La Puente Homes Are Different
Most of La Puente’s housing stock went up between the mid-1950s and early 1970s. That means single-pane windows, original duct runs, and electrical panels sized for an era before central air became standard. We regularly see 100-amp panels on Valley Boulevard-area homes trying to support a modern AC plus a heat pump retrofit. The fix is not always bigger equipment. Sometimes it is duct sealing, sometimes it is a panel evaluation before installation day, and sometimes it is simply repairing what a previous technician misdiagnosed.
The terrain matters too. Homes in the northern foothills sit on sloped lots that make condenser placement and drainage more particular than a flat suburban yard. And the summer heat arriving off the Valley floor pushes attic temperatures well past 130 degrees, which ages capacitors, contactors, and fan motors faster than in coastal cities. A 10-year-old AC in La Puente has often done the work of a 15-year-old unit somewhere cooler. That changes the repair-versus-replace math, and we tell you the truth about which one makes sense before any money changes hands.
Our Main La Puente Services
These are the two jobs La Puente homeowners call about most, each with its own page so you get the full picture on cost, process, and what to expect.
AC Repair in La Puente
When an AC quits in July out here, the house gets uncomfortable fast, and attics make it worse for the equipment. We find failed capacitors, refrigerant leaks, clogged drain pans, and dead fan motors. Every repair gets a written diagnosis and a fixed price before work starts. Most jobs are done in one visit, and if the repair fails inside a year, we return at no charge. Full detail on the AC Repair in La Puente page.

Heat Pump Installation in La Puente
La Puente winters are mild enough that a heat pump often handles both cooling and the occasional cold night without gas backup. Older homes may need a panel check and duct assessment first, which we include before quoting. This is load-calculated, ordered, and scheduled work, never same-day. You get a written, fixed price and a set install date. See the Heat Pump Installation in La Puente page for the full breakdown.

Furnace Repair in La Puente
Furnaces run less in La Puente than in colder climates, which means more failures from neglect than wear. We see flame sensors, inducer motors, and control boards that failed because the unit sat unused for months. Repairs are diagnosed in writing, priced before we start, and covered by our full-year written guarantee. The details are on the Furnace Repair in La Puente page.
