HVAC Company in Duarte, CA
Meadowsweet Heating & Air is the HVAC company in Duarte, CA that treats foothill homes like they’re our own. Duarte sits where the San Gabriel Valley floor rises into the mountains, and that changes everything about how heating and cooling systems perform here, from 100°F summer afternoons to Santa Ana wind events that push smoke down the canyons. We handle AC repair, furnace repair, and AC installation for the ranch-style tract homes that make up most of this city, always with a written price before any work starts. Call us at (747) 966-3037 and a live person answers, day or night.
Why Duarte Homes Are Different
Duarte sits at a thermal pinch point. The valley floor meets the San Gabriel Mountain foothills right here, and that geography pushes summer temperatures 10 to 15 degrees hotter than coastal Los Angeles, routinely above 100°F. The same canyons that heat the city also funnel downslope Santa Ana winds and wildfire smoke from the mountains directly behind town. An HVAC system in Duarte has to handle extreme cooling loads and real air-quality threats in the same season, which most flatland systems were never designed to do.
The housing stock adds another layer. Most Duarte homes are single-story ranch-style tract houses built between the late 1950s and mid-1970s. Their duct systems, often original or early replacements, run through unconditioned attics that bake past 140°F in summer. That heat blows out flex duct connections and quietly drains efficiency. We find this constantly on the foothill streets above Huntington Drive, where south- and west-facing attics on the steeper grades bake hardest. Duarte’s position inside the San Gabriel Valley’s inversion layer also means ozone and particulate levels run high, so filtration upgrades like MERV-13 or better matter here far more than they do closer to the coast.
Our Main Duarte Services
Most Duarte homeowners call us for two reasons: a system that stopped cooling in July or a furnace that won’t fire on a cold January morning. When a replacement is the smarter call, we handle that too. Each service has its own dedicated Duarte page below.
AC Repair in Duarte
When your air conditioner quits on a 102°F Duarte afternoon, you need a technician who understands what this climate does to equipment. We diagnose everything from failed capacitors and contactors to refrigerant leaks and blown duct connections in attics that have been roasting all day. Our crews work fast but carefully, with shoe covers on every floor surface and drop cloths under the work area. We service Carrier, Trane, Lennox, Rheem, and more, and every repair comes with a written price before we touch a single part. See what’s involved on our AC Repair in Duarte page.

Furnace Repair in Duarte
Duarte winters are mild by national standards, but a dead furnace on a 40°F night with kids in the house is urgent. We repair gas furnaces, heat exchangers, igniters, blower motors, and thermostats across the ranch homes and newer builds throughout the city. The foothill angle matters here too: homes on sloped lots often have furnaces tucked into tight closets or attic spaces that need careful, clean work. Our technicians follow the C.A.R.E. values on every visit: clean up like it’s their own home, ask before moving anything, respect quiet hours. Details are on the Furnace Repair in Duarte page.

AC Installation in Duarte
A new air conditioner in Duarte has to be sized for real heat, not a coastal guess. Load calculation matters when your attic hits 140°F and your ducts run through unconditioned space. We install high-efficiency systems from brands like Trane, Lennox, Goodman, and Rheem, with options for the filtration upgrades this airshed actually needs. Every installation includes a fixed written price, a set install date, and the 365-Day Done Right Promise behind the whole job. Read the full breakdown on our AC Installation in Duarte page.

Brands We Service in Duarte
Our technicians are qualified to service equipment from nine leading manufacturers, including Trane, Lennox, Goodman, and Rheem. That breadth matters in Duarte, where a 1960s ranch home might have a 25-year-old Goodman sitting next to a two-year-old Lennox in the house down the street. We stock common parts locally so repairs move quickly. See the full list on our brands page.
Pricing for HVAC Company in Duarte, CA
| Service | Typical range in Duarte |
|---|---|
| AC repair | $150-$650 |
| Furnace repair | $150-$700 |
| AC installation | $3,500-$7,500 |
| Tune-up | $80-$200 |
What pushes a Duarte repair toward the higher end of that range is usually the attic: duct damage from extreme heat exposure, or a system that’s been working against 140°F attic temperatures for years. The lower end covers simpler fixes like capacitors, igniters, and thermostat replacements. Whatever the number, you’ll see it in writing before any work begins, never as a surprise on the invoice.

What Duarte Customers Say
"Furnace tune up before winter. He was careful going in and out, closed the gate behind him every time because of the kids, and cleaned up the work area completely. Calm, thorough guy."
- Marcus Pell"Comfortable in every room now, and not a trace that a crew had been here. Booties, drop cloths, the works. They even wiped down the thermostat they'd handled. Really considerate."
- Lamar Finch"New system install. They protected the hallway floor all the way to the attic and vacuumed after. Worked quietly around my work calls. Not a trace left behind."
- Rosalind Okeke
