Nine more swaps from around the valley are on the project showcase.
What the furnace trucks became
Four trades, one number since 1947
Theisen started out vacuuming furnaces and smoke pipe. The work grew into full heating and cooling, and the cleaning never left the truck.
Air conditioning
A/C repair and new condensers
For the weeks it sits over 100. Same-day help when the schedule allows, honest repair-or-replace advice, and new condensers set level on fresh pads.
Air conditioning
Ductless
Mitsubishi ductless mini-splits
Heat and cooling for rooms the ductwork never reached. Installs, refrigerant and electrical repairs, and the cleaning that keeps a wall head from smelling.
Ductless
Since 1947
Furnace and duct cleaning
The trade on the old truck doors. Clogged ducts starve airflow and can become a fire hazard, so the vacuum still comes out every season.
CleaningPainted on the truck door
The same 4787 since the furnace cleaning trucks
The 1950s Theisen Furnace Cleaning trucks carried GL 2-4787 on the door. The shop still answers (509) 452-4787. Different owners, different equipment, the same number to call when the house goes cold.
- 1947Theisen starts cleaning Yakima furnaces with a power vacuum truck: filters, smoke pipe, ducts.

- 2023Ryan and Lacey Cyr take over and widen the work to full heating, cooling and ductless.

What the valley says after the truck leaves
“the Theisen Team navigated the power company maze to submit and then RE-submit the Power Company's rebate process -- which meant I will get a check for $2,000 as a rebate.”
The first claim had been denied. “This refund would not have happened without their help, as the initial claim was denied.”
“My hot water heater went out 1 day before vacation. Owner Ryan came out, gave an estimate, got the crew and electrician out same day. How accommodating and efficient service. Great job”
“I used Sam and Dennis at Theisen for the 25 years I lived in Yakima and was hesitant when I found out they sold it and retired. I was right to stick with the new owners, of course they would have sold it to good people. My A/C unit went out and I had to replace everything on a Friday of course. The new owners not only got it done by Monday but let me use a plug-in unit for the weekend. It was 96 degrees inside, so I was very grateful. The new owners treated me good, were very respectful and so were their employees. They have my trust in return.”

Yakima, Selah, West Valley, Ahtanum, Moxee, Naches, Parker and Wapato. The shop is at 1014 N 34th Ave in Yakima, so most of the valley is a short drive.
Monday through Friday, 8:00 AM to 5:00 PM. Call (509) 452-4787 or email theisenheating@gmail.com and the office will set a time.
We generally suggest a routine service every other year. Plenty of Yakima customers book us every fall anyway, because the furnace runs better after a cleaning and filter change going into winter.
Yes. One customer's rebate claim was denied the first time; we resubmitted it, and the second submission meant a $2,000 rebate check. Ask about rebates when we bid the job.
No, we don't normally service gas fireplaces. Call a fireplace specialist for those so you don't pay for a trip we can't finish.
Most of our installs are American Standard furnaces, air handlers, heat pumps and condensers. We also carry Lennox, Mitsubishi ductless, Generac standby generators, Navien, Honeywell and Heat & Glo.
