AfterHVAC Company in Glendora, CA
Dalton Heating & Air handles HVAC work in Glendora, CA, where foothill heat, older duct systems, and tight property lines all shape how an air conditioner or furnace gets fixed or replaced. We give every Glendora homeowner a written price before any work starts, and every repair carries a full-year written guarantee. If something fails inside that year, we return at no charge. You can reach a real person at (361) 306-9515 any hour, any day. What most people want to know first is what the job costs and who is showing up. Both answers are concrete, and they are below.
Why Glendora Homes Are Different
Glendora sits against the San Gabriel foothills, which means summer afternoons push well past 100 degrees on streets north of the 210 while evenings cool down fast. HVAC systems here cycle hard. A condenser that spends ten hours a day pulling 110-degree air through the coil works differently than the same unit in a coastal climate, and we account for that when we size repairs or quote a replacement. Homes built across the 1950s through the 1980s still carry original duct runs in many cases, with returns that were undersized even by the standards of their day. That is a real constraint. You can put a modern system on old ductwork, but the airflow numbers have to work or the new unit never performs to its rating.
Lot sizes in Glendora also change the job. Many neighborhoods, especially south of Foothill Boulevard, have narrow side yards where an outdoor condenser has to meet five-foot clearance rules and still leave room to walk. North of Sierra Madre Avenue, rooflines get steeper and attics tighter, so routing a new lineset or replacing a plenum takes more care than a wide-open Southern California tract home. We plan for that before we quote, because finding out during the install is the thing homeowners are most right to hate.
Our Main Glendora Services
Most calls in Glendora come down to two situations: an air conditioner that stopped cooling or a furnace that will not light. Heat pump installation has also picked up as homeowners replace aging gas furnaces with electric systems that heat and cool from one unit. Each of these has its own Glendora page with detailed pricing and what the job involves.
AC Repair in Glendora
An AC repair in Glendora usually starts with a system that ran fine through the fall, sat mostly idle through the mild winter, and then failed on the first 95-degree day. Capacitors, contactors, and fan motors are the common culprits. Those are small electrical components that start and run the outdoor unit, and they wear out faster in foothill heat. We arrive with common parts on the truck, diagnose the system, and put the repair price in writing before touching anything. Learn what the job costs and what is covered on our AC Repair in Glendora page.
Heat Pump Installation in Glendora
Heat pumps are a strong fit for Glendora because our winter lows rarely get cold enough to challenge a modern cold-climate unit, and the same system that heats the house also runs the air conditioning all summer. It is one outdoor unit doing both jobs. The install usually includes replacing the indoor air handler, running a new lineset, and confirming the existing ductwork can move enough air. Sizing matters, and we run the load calculation before we quote a number, not after. Full details, including the range of installed cost, are on our Heat Pump Installation in Glendora page.
Furnace Repair in Glendora
A furnace that will not fire usually fails on the first cold morning it is actually needed, which in Glendora often means a December night in the low 40s. Igniters, flame sensors, gas valves, and draft inducer motors are the parts we replace most. That last one, the inducer, is a small blower that vents combustion gas out of the flue. When it fails, the furnace locks itself out for safety, which is the right behavior. We service all major brands and stand behind every repair in writing for a year. See typical repair costs and what a same-day visit looks like on our Furnace Repair in Glendora page.

Pricing for HVAC Company in Glendora, CA
These are the ranges we charge across Glendora. The spread is wide because a capacitor swap and a condenser motor replacement are not the same job. The price is in writing before we start, every single time.
| Service | Typical range in Glendora |
|---|---|
| AC repair | $150 – $650 |
| Furnace repair | $150 – $700 |
| AC installation | $3,500 – $7,500 |
| Tune-up | $80 – $200 |
What pushes a Glendora repair toward the top of those ranges is usually access. A condenser squeezed into a side yard with a drainage swale on one side and a block wall on the other takes longer to work on than one with open space, and attic furnaces with steep roof pitches are slower to reach and slower to button back up. None of that changes how we bid: the price is written before any work begins, and it does not move at the door.
