HVAC Company in Redmond, WA

Most HVAC calls we get in Redmond involve homes built during the Microsoft campus expansion from 1985 to 2005 that were never designed for cooling. These houses run on original gas furnaces with duct systems that need careful modification before a heat pump or AC can work properly. Our technicians are trained on nine major brands including Goodman, Rheem, and Daikin, and every repair comes with a written 365-Day Done Right Promise. If your furnace quits on a foggy January morning or you’re finally adding AC after the last heat dome, call us at (817) 402-2972. We answer live, 24 hours a day.

Why Redmond Homes Are Different

Redmond’s housing boom left a specific legacy. Thousands of homes on Education Hill, in Bear Creek, and around Overlake were built with gas furnaces only, on the assumption that Pacific Northwest summers would stay mild. The 2021 heat dome changed that assumption for good. Now we’re regularly retrofitting heat pumps into heating-only duct systems, a job that barely exists in cities with newer stock.

The geography compounds the problem. Redmond sits in the Sammamish River valley, which holds marine moisture and morning fog longer than elevated Bellevue or Kirkland. Crawl spaces stay damp from October through April, accelerating mold around poorly sealed duct boots. Most of these homes have ducts running through unconditioned crawl spaces, so moisture intrusion and duct sealing are persistent issues we address on nearly every job.

The original 80,000-100,000 BTU single-stage Carrier or Lennox furnaces from the mid-1990s are still running in many of these houses. Their ducts were intentionally oversized for heat distribution, but that same sizing creates static-pressure problems when a heat pump’s air handler tries to push cooling airflow through the same trunk lines. We often need a blower-speed audit and damper balancing before the new system will pass King County inspection. This isn’t a generic install; it’s a retrofit problem specific to Redmond’s era of tech-suburb buildout.

Our Main Redmond Services

Redmond homeowners call us most often for these three jobs, each shaped by the local housing stock and climate conditions.

AC Repair in Redmond

AC repair in Redmond usually means a system that was added to a house never designed for cooling. We find refrigerant leaks at linesets run through crawl spaces, compressor strain from mismatched coils, and airflow issues caused by ducts that were sized for heat only. Our technicians carry common parts for Goodman, Rheem, and Daikin systems, and most repairs are completed same day. Every repair includes a written price before we start and a 365-Day Done Right Promise before we leave. AC Repair in Redmond

Furnace Repair in Redmond

Furnace repair in Redmond often involves those original mid-1990s gas units still heating homes on Education Hill and in Bear Creek. We replace failed igniters, clean flame sensors fouled by valley moisture, and track down intermittent pressure-switch problems caused by blocked venting through damp crawl spaces. Because these systems are past their design life, we always explain whether a repair makes sense or if a heat-pump conversion is the smarter path. Furnace Repair in Redmond

AC Installation in Redmond

AC installation in Redmond is increasingly a heat-pump retrofit into existing heating-only ductwork. We start with a load calculation and static-pressure test, then modify or seal ducts as needed before the new air handler goes in. King County’s electrification incentives and the reality of hotter summers make this the dominant new-system job in Redmond. We handle the rebate paperwork and provide a fixed written price that doesn’t change at the door. AC Installation in Redmond

What Redmond Customers Say

★★★★★ 4.8 from 6+ reviews

"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."

- Natalie Esposito
