Heat pump and gas furnace installation in the Tri-Cities
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.

A heat pump or a gas furnace: the choice depends on your fuel, your ducts and your winters
Eastern Washington winters are cold and dry, with hard snaps that heating equipment has to be selected and sized for. A heat pump also cools the house in summer, so one outdoor unit covers both seasons. A gas furnace makes strong heat regardless of the outdoor temperature and pairs with a separate air conditioner. A-One also installs electric and oil furnaces.
The right choice depends on what you already have. A house with a gas line and sound ducts may keep a furnace and add efficient air conditioning. A house heated with electric resistance often has the most to gain from a heat pump. A dual fuel setup pairs a heat pump with a gas furnace as backup. A good tech lays out the tradeoffs and lets you weigh utility rates, rebates and how you use the house.

Load, ducts and installation decide whether the new equipment heats the house evenly
Installation starts with a load calculation for the house, not a swap for the same size as the old unit. The tech measures the rooms, checks insulation and windows and looks at how the old system performed. Duct size, static pressure and the return path come next, because ducts built for an old, smaller blower can choke a modern variable speed unit. A-One uses duct leakage testing and blower door testing.
On the day, the crew sets the furnace or air handler level, connects and tests the gas line, venting and drain, and sets the outdoor unit on a pad. For a heat pump, the line set is flushed or replaced, the system is pressure tested, pulled to a deep vacuum and charged by measurement. The tech sets airflow and thermostat settings, including defrost and backup heat behavior, and walks you through the system before leaving.

Rebates, warranties and the first winter are part of the job
A-One says it holds the certifications needed to help customers qualify for utility rebates through Benton PUD, Benton REA and the City of Richland, and it works with Tri-Cities Credit Union and Numerica Credit Union on financing. Ask about programs and paperwork before you choose the equipment, since rebate terms tie to what gets installed and programs change.
As a Certified Amana Dealer, A-One provides a 10-year warranty on parts and labor for all new Amana systems, as well as a lifetime warranty on the compressor. That covers new Amana systems only. During the first winter, watch how the heat pump defrosts, how evenly the rooms warm and how the system sounds on the coldest mornings, and tell the shop if anything seems off.
