Protect Yourself With a Reliable Carrier Gas Furnace

One of the biggest and most essential investments in your home, your gas furnace protects you and your family throughout the winter. That's why, here at R.A. Heating & Air Conditioning, we feature Carrier products and are a factory-authorized dealer.


A modern Carrier furnace can be up to twice as efficient as many 10-year-old models, saving you up to 50% in operating costs and offering 98.5% energy efficiency. Over their lifespan, they can pay for themselves many times over!


Carrier furnaces are available in the economical Comfort line, the efficient Performance line, or the advanced Infinity series.

59MN7 Infinity® 97 Gas Furnace

The 59MN7A Multipoise Variable – Capacity Condensing Gas Furnace features the modulating Infinity® System. The innovative modulating gas valve is at the heart of this furnace’s quiet operation, along with the variable-speed Infinity ECM blower motor and variable-speed inducer motor. This furnace also provides 3.5 times tighter temperature control than single stage furnaces. With an Annual Fuel Utilization Efficiency (AFUE) up to 98.5%, this Infinity gas furnace provides exceptional savings over standard furnaces as well. This Infinity Gas Furnace also features 4-way multipoise installation flexibility. A Carrier Infinity® Control and an Infinity Air Conditioner or Heat Pump can be used to form a complete Infinity System.

59TP6 Performance™ Series 96

The 59TP6A Two-stage Multipoise Performance™ Condensing Gas Furnace features two-stage heating comfort along with SEER-boosting year-round electrical efficiency. The Comfort Heat Technology® two-stage gas valve is at the heart of the comfort provided by this furnace, along with the electrically-efficient Variable Speed ECM blower motor, and two-speed inducer motor. With an Annual Fuel Utilization Efficiency (AFUE) of up to 96.7%, this Performance™ Series two-stage gas furnace provides exceptional savings when compared to a standard furnace. This gas furnace also features 4-way multipoise installation flexibility, and is available in five model sizes. All units meet Air Quality Management District emission requirements.

58STA Gas-Fired Furnaces

The 58STA 4-way multipoise gas furnaces feature Carrier’s QuieTech™ noise reduction system for incredibly quiet induced draft operation. Applications are easy with 4-way multipoise design, through-the-furnace down-flow venting, 13 different venting options, and a door designed for easy service access. An inner blower door is provided for tighter sealing in sensitive applications. The 58STA furnace is approved for use with either propane or natural gas. The 58STA furnace is approved for use with natural or propane gas, and for use in Low NOx Air Quality Management Districts.

Carrier® Comfort™ Series – Condensing Gas Furnace

If you could look under the hood of a Carrier® Comfort™ Series condensing gas furnace, you’d see what drives the performance: a serious commitment to quality. To squeeze as much of the heating efficiency from the gas you use as possible, Comfort Series condensing gas furnaces include two heat exchangers. The primary heat exchanger does most of the work while a secondary heat exchanger squeezes additional heating energy to optimize savings and comfort.


When combined with a compatible Carrier thermostat, ComfortFan™ technology allows fan-speed choices in “constant on” mode. And, the PowerHeat™ hot surface ignition brings reliability and durability for years of comfort you can depend on and reduced gas usage due to eliminating the pilot light.

We had some trouble over the winter with our furnace and they tried to help over the phone as it was a Friday night and freezing. When the tech was at the house he took the time to explain how the system worked and why our problem was happening and even how to fix it ourselves in the future if we wished (this was a minor problem). Super responsive and helpful. They have earned our business for years to come for sure.
