Heating and cooling in the Tri-Cities
One crew for the furnace, the air conditioner and the ducts between them, for homes and for businesses. A-One has worked in Tri-Cities heating and cooling since 1980.
HeatingCoolingAir quality
One crew handles the heat, the cooling and the air in between
A-One takes care of heating, cooling and air quality with one crew, for homes and for businesses. You do not have to coordinate a furnace company, an air conditioning company and a duct company that never compare notes. The same team knows how the furnace, the coil, the ducts and the filter affect one another, so a comfort problem gets traced to its real cause.
That covers a cold January morning, a 100 degree July afternoon and the dusty air in between. A minor repair and a full system replacement start the same way, with one call to the shop in Pasco. The crew serves Pasco, Kennewick, Richland, West Richland, Benton City and Burbank, and takes emergency calls 24/7.
Seven servicesOne crew
Repair, maintenance and installation for every part of the system

AC repair
When the air conditioner quits in a Tri-Cities heat wave, A-One measures the system, finds the part that actually failed and fixes that. Emergency service runs 24/7.
The usual culprits are a weak capacitor, a pitted contactor, a low refrigerant charge or a coil clogged with Tri-Cities dust. The tech measures first, so the part that gets replaced is the one that failed.
AC maintenance and tune-ups in the Tri-Cities
A yearly AC tune-up from A-One covers the system from the outdoor coil to the condensate drain, before dust and 100 degree afternoons turn a weak part into a breakdown.
AC replacement and installation in the Tri-Cities
A-One sizes the system to the house, checks the ducts and installs Amana, Daikin or Goodman equipment. A-One is also a Lennox Premier Dealer.
Furnace and heat pump repair in the Tri-Cities
A-One checks gas, venting and safety controls first, then finds the exact part that failed in your furnace or heat pump. Emergency service runs 24/7.
Furnace and heat pump maintenance in the Tri-Cities
A heating tune-up from A-One follows the furnace or heat pump from thermostat to exhaust, so weak parts are found in the fall and not on the coldest night.

A-One sizes a heat pump or furnace to the house, checks the ducts and installs it with a tested line set and gas connections. Ask about rebates and financing.
