Natural Gas Furnaces

Reliable

Direct Hot Surface Ignition System features an advanced silicon nitride igniter for years of reliable starts.

Durable

The RPJ® III primary heat exchanger is made of corrosion-resistant weld-free stainless steel. The unique integrated ripple-edged design forces more heat to the outside surface area for higher efficiencies.

Heating On Demand

Two-stage redundant gas valve, two-speed induced draft blower assembly, and variable speed motor operate normally at the lower stage and ramp up as needed.

Quiet

Variable speed circulation blower motor is pre-lubricated, dynamically balanced, and resilient mounted to reduce vibration and noise.

System Monitoring

State-of-the-art electronic controls monitor system operation and allow for advanced diagnostics, a timesaving tool for technicians.

Air Conditioning

Quiet

The Copeland® scroll compressor operates without noisy pistons and comes with a deluxe sound blanket to reduce compressor sound levels. Two-stage operation means it runs mostly in the lower, quieter stage and switches to the higher stage in higher temperatures for more cooling.

Durable

The galvanized steel cabinet features a coated inlet grille with narrower spacing to provide maximum protection as it allows for proper airflow and easy coil cleaning.

Efficient

The scroll compressor and the 7 mm copper tubing with aluminum fin coils work collectively to save on energy.

Smooth Operation

The two-speed fan motor operates most of the time on quieter, lower speed. Aerodynamic air discharge design reduces operating sounds. Matching with variable speed indoor fan allows whisper-quiet indoor operation.

Service Friendly

The Comfort Alert II system has all of the standard comfort alert features. Plus, it can alert homeowners to call for service before a problem develops by working with an optional Comfort Alert II compatible thermostat.
