A-One Air: heating, cooling, electrical and plumbing for the Tri-Cities since 1980
One family shop on N 20th Avenue in Pasco, and one number on every van. Call it for a furnace that quit, a breaker that will not hold or a water heater that finally gave up.

PascoSince 1980Second generation
The sign on N 20th Avenue lists five trades. One shop does all of them.
Al and Carol Hagen started A-One in 1980 on commercial refrigeration. Customers kept asking for more, so the shop added cooling and heating, then electrical, and now plumbing. Their son Kyle runs it today.
That history is why one call covers the furnace, the panel and the water heater. The same crew knows how the systems in a house lean on each other, and the shop still tests for the cause with blower door and duct leakage testing before it sells a fix.

What A-One customers say on Google
“Our AC quit working in the 100 degree heat. Taylor came at 8 pm and fixed it really fast. The 2nd day he came right away when something else went wrong. For the 3rd day in a row, superhero Taylor came to the rescue.”
“They were quick and efficient when installing my new system, and they were always willing to answer any questions I had afterward. When I felt like my system wasn't getting as cold as I had expected, they came out the same day to check everything and address my concerns.”
“He was on time, very professional with outstanding customer service skills. He did the best job and the price was reasonable!”
