AfterHVAC Company in Temple City, CA
Temple City homeowners face a unique challenge: summer temperatures regularly hit 100-105°F, yet most houses here were built in the 1950s-70s without central air conditioning. At Coldharbour Heating & Air, we’re the local team that handles full HVAC retrofits in these older ranch homes, from wall-furnace replacements to complete ductwork design-builds. Our technicians are trained on nine major brands including Rheem, York, and Daikin, and every repair comes with our written 365-Day Done Right Promise. Call (817) 402-2972 and a live person answers, day or night.
Why Temple City Homes Are Different
Temple City sits on the San Gabriel Valley floor, pinned between the San Gabriel Mountains and the Puente Hills. That geography blocks the Pacific marine layer almost entirely, so summer heat lingers 15°F above what coastal LA feels, and heat waves stick around longer than in foothill neighbors like Arcadia. Fall Santa Ana wind events bring rapid low-humidity swings that stress aging furnace heat exchangers.
The housing stock compounds the problem. Temple City’s dominant single-family ranch homes, built roughly 1950 to 1975, were originally fitted with wall or floor furnaces and window-unit cooling. Where ductwork exists, it’s often undersized galvanized sheet metal that has corroded or sagged after decades of attic heat exposure. A large share of our service calls involve homes with zero ductwork, no plenum, and no viable attic clearance, meaning we design from scratch rather than swap equipment. SCAQMD ultra-low-NOx furnace requirements add another layer, every new furnace installation must meet strict emissions standards that affect model selection and venting design.
Our Main Temple City Services
Most calls we get from Temple City fall into three categories: cooling repair during summer heat waves, furnace repair when Santa Ana winds expose cracked heat exchangers, and full system installation for homes that never had central air.
AC Repair in Temple City
When a compressor fails on a 102°F August afternoon in Temple City, speed matters. We stock capacitors, contactors, and refrigerant for common systems, and our technicians carry digital gauges calibrated for the R-410A and R-32 refrigerants found in newer units. Many Temple City homes still run legacy R-22 systems, when we find a leak in one, we explain the repair cost against replacement options honestly. AC Repair in Temple City covers everything from refrigerant recharges to full compressor replacement.
Furnace Repair in Temple City
Wall furnaces and early floor furnaces are still common in Temple City’s 1950s-60s neighborhoods. We repair standing pilot ignition systems, replace cracked heat exchangers, and upgrade to modern direct-vent units where possible. Fall Santa Ana events push these aging systems hard, and we see a spike in heat-exchanger cracks when humidity drops suddenly. Every repair includes our written 365-Day Done Right Promise. Furnace Repair in Temple City handles both emergency no-heat calls and seasonal safety checks.
AC Installation in Temple City
Homes without existing ductwork need creative solutions. We evaluate small-duct high-velocity systems and ductless mini-splits for finished spaces where opening walls isn’t practical. Load calculations account for Temple City’s true inland heat gain, not coastal assumptions. Permits pull through Los Angeles County, and we handle SCAQMD compliance documentation for any gas furnace component. AC Installation in Temple City covers full design-build projects and central system upgrades.

What Temple City Customers Say
"The repair was done well and quickly. Scheduling over the phone was a little clunky and I got transferred twice, but the tech himself was great and on time."
- Brett Haygood"Furnace was short cycling all winter. They diagnosed a bad sensor instead of condemning the whole unit like I feared. Cheap fix, honest call."
- Russ Tiedemann"Thermostat and a weak blower. Fixed both in one visit, explained the guarantee, and didn't leave a mess. I've already recommended them to my neighbor."
