Furnace repair, new heating systems and routine service in Yakima
Yakima's winters average a low of 24 degrees Fahrenheit in some months. When the furnace quits in that stretch, you want the shop that has answered the same phone number since 1947.
Chapter 01
What fails when the Valley drops to 24 degrees
A furnace rarely dies on a mild day. It waits for the first hard freeze, when it has run for hours and every weak part gets its turn to fail. The calls that come into the shop are the ones you would recognize: no heat at all, a blower that runs but pushes out cold air, a burner that lights and shuts itself off, a furnace that cycles on and off without ever warming the house, or a new noise that was not there last winter.
Behind those symptoms sit a short list of suspects. A worn igniter that no longer lights the burner. A blower motor that has given up. A clogged filter that starves the system of air. A flue or smoke pipe that has loosened from its joint. A condensate line that has backed up on a high-efficiency unit. And on an older furnace, the heat exchanger, the part you cannot see and most want checked.
Dave Johnson called Theisen for a routine check-up and learned he had a fire hazard with his original heater. The crew came out and replaced both the heater and the air conditioner, on time and within budget. Gwyn M., whose family had used the shop for years, called after a mid-winter system failure and watched Ryan's crew handle the removal and the new install in one go. Both stories started with a phone call to (509) 452-4787, from Yakima, Selah, West Valley, Moxee, Wapato, Naches, Parker or Ahtanum, on a weekday between 8 and 5.

How a heating job runs, from first look to city inspector
The first visit is diagnosis, and it is honest about the answer. Plenty of furnace calls end with a repair: a new igniter, a replaced blower, a cleared condensate line, a fresh filter. When the unit is past saving, you get a bid for a replacement. David Eldred, who needed a furnace replaced, described the shop as diagnosing on short notice, giving very competitive bids, and then doing what they said when they said they would.
When a furnace does come out, the job is old unit out and new unit in, one house at a time. Most of what Theisen installs today is American Standard, and Lennox is also carried. The crew disconnects the old furnace, sets the new one, connects the flue, the gas and the electrical, runs the condensate line where the unit calls for one, and tests the system before leaving. Gwyn M. wrote that every part of the removal and installation was orchestrated with professionalism and courtesy.
The paperwork is part of the job too. Chris Gordon wrote that the crew held his hand through the city inspector process. David Eldred's team submitted the power company's rebate after his install was finished, then re-submitted it when it needed another pass, and he ended up with a $2,000 rebate check he said he would not have gotten on his own.
Chapter 03
Keeping a furnace honest after the install
Theisen generally suggests a routine service every other year. Some customers do not wait that long: one Yelp reviewer has the shop out at the start of every winter, and says he likes how his furnace runs better after the work. Many Yakima households book in the fall, before the first cold week, so the heat exchanger, flue, blower, igniter and filter have all been looked at before they are needed.
That fall visit is also where problems get caught while they are cheap. A loose smoke pipe, a tired igniter and a plugged filter are all easy to fix on a mild October afternoon and miserable to deal with at 24 degrees. It is the same logic behind Dave Johnson's check-up: someone looked at the heater before it hurt anyone.
