HSPF2 stands for Heating Seasonal Performance Factor and is a measurement of a heat pump’s heating efficiency. As with SEER2, HSPF was updated to HSPF2 to help reflect your system’s performance after installation.

The ENERGY STAR program is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy helping us all save money and protect the environment through energy-efficient products and practices.

Rather than running at only one or two speeds, the inverter-driven compressor changes its speed in small, precise increments like a dimmer switch to provide longer, gentler run cycles. That means temperatures are held exactly where you want them, even in extremely hot or cold weather.

MHT™ Technology helps transfer heat in and out of your home more efficiently. Featuring lanced coil fins for greater coil-to-air contact, rifled tubing for enhanced refrigerant flow, and a fan venturi cover to focus air flow over the coils to more efficiently remove heat in cooling mode and absorb heat from the air in heating mode. That means our air conditioners and heat pumps are designed to last longer and help ensure your home stays consistently comfortable. 

The combination of a gas furnace and an electric heat pump pairs two energy sources for the perfect balance of energy efficiency and comfort.

When properly matched with a variable-speed furnace or air handler, your outdoor unit can, in many cases, provide an elevated SEER rating.

Pair this model with a Pro Series™ variable-speed furnace and a Comfort Sync® A3 Thermostat, for optimum performance. With higher energy efficiency, premium technology and a smart thermostat, our Pro Series™ systems give you the highest degree of control over your home environment. Explore the full Pro Series™ line.

When you pair this model with the Comfort Sync® A3 Thermostat, you unlock total control over your home environment from anywhere. Program your Comfort Sync® app once and enjoy the freedom of fully intelligent heating and cooling. Your system adapts to deliver total harmony across your home, all on your schedule, so you can spend more time enjoying your home, and less time tinkering with thermostat settings.

Rather than running at just one speed, the 18LX Inverter-Driven Scroll Compressor is able to run at lower speeds and longer cycles, removing more humidity from the air for a more dry, consistently comfortable home environment.

Each of our matched indoor air coil units feature drain pans treated with Microban antimicrobial protection. It stops the growth odor-causing mold and mildew on contact and helps ensure long-lasting performance.

Allows heat pumps to enter defrost mode without excessive noise. Since refrigerant pressure is allowed to equalize before the switch, the heat pump can dissipate performance-robbing frost and ice quietly.

Greatly reduces operating sound so your outdoor entertaining is not interrupted.

Rather than running at just one speed, the inverter-driven compressor is able to run at lower speeds and longer cycles. That means approximately 50% lower noise levels compared to a 14 SEER single-stage unit for comfort you'll never have to think about.

High-tech design allows for better sound control and is engineered for long-lasting durability.

The combination of both high- and low-pressure switches give additional reliability to each of our outdoor units. The high-pressure switch prevents operation if refrigerant pressures exceed safe levels, protecting the compressor. If your unit does not have enough refrigerant, the low-pressure switch prevents the unit from drawing in moisture and other contaminants while operating.

When you pair this model with the Comfort Sync® A3 Thermostat, your thermostat communicates with each component, making constant adjustments and sending regular maintenance reminders to your smart phone to ensure your entire system is always working in harmony for your ideal environment.

Select outdoor units feature Omniguard® Total Corrosion Protection Technology, offering improved corrosion protection compared to traditional coils and preserving the life of your system for years to come.

Our outdoor units use a sealed contactor with lugs to provide a safe and secure power connection, and the lugs help technicians during routine maintenance.

Our dedication to engineering a better product is backed by a 10-Year Limited Warranty on parts and extended warranty options including full unit replacement on equipment installed by a registered ComforTeam or ProTeam dealer.*
