The Most Efficient Heating and Cooling System Available Today

If you are looking for a new heating and cooling system for your home, you may be asking, ‘What is the best or most efficient system out there?’

Well, search no further. ClimateMaster’s Trilogy® 45 geothermal heat pump system exceeds 45 EER, the industry's current highest rating.

EER stands for Energy Efficiency Rating and is used to rate the cooling efficiency of geothermal heat pumps by the Air Conditioning, Heating, and Refrigeration Institute/International Standards Organization. Generally speaking, the higher an EER, the more efficient your system is, and the more money it can save you on your home’s utility bills.

In addition, the Trilogy 45 system is recognized as ENERGY STAR® Most Efficient 2019 for exceeding stringent efficiency requirements. You can read more about the Trilogy 45 system on ENERGY STAR’s Most Efficient 2025 web page here.

Why is the Trilogy 45 system more efficient than any other heating and cooling system?

The Trilogy 45 is so efficient because of how it operates. Traditional heating and cooling systems start delivering heat or cooling and then stop when the desired temperature is reached. Turning on or restarting heating or cooling requires a lot of energy.

Meanwhile, the Trilogy 45 system runs at lower speeds for longer periods, maintaining a constant level of comfort while using less energy because it doesn't constantly turn off and on.

The Trilogy 45 system is designed to operate slowly and consistently for peak efficiency and peak savings. On an extremely hot or cold day, the Trilogy 45 speeds up and delivers full comfort (capacity) regardless of the outdoor air temperature.

Patent-Pending Hot Water Technology = Even More Energy Savings

Domestic hot water is now the second largest user of energy in US homes today (even more than air conditioning in most places in the United States )¹.

To reduce hot water costs, ClimateMaster developed a patent-pending technology called Q-Mode® that delivers over 80% savings by generating year-round, full-time hot water at 500%+ efficiency.

Additionally, Q-Mode provides additional energy savings from free cooling when simultaneously heating water. Q-Mode makes Trilogy unique among other products by enabling such low operating costs.

While delivering ultra-high efficiencies, you don’t have to compromise on comfort. Our Trilogy geothermal heat pump system recovers hot water more quickly than traditional water heaters, delivering more hot water without needing a larger tank.

An Award-Winning Heating and Cooling System

Our Trilogy system was recognized as one of the top 100 most technically significant products introduced in the marketplace. Co-developed with Oak Ridge National Laboratory, Trilogy Q-Mode won a prestigious R&D 100 Award in 2013, recognizing Trilogy’s groundbreaking improvements in heat pump technology and energy efficiency.

The revolutionary Trilogy 45 represents a major breakthrough in comfort and efficiency, continuing ClimateMaster’s legacy of innovation. Watch our video about ClimateMaster: 50 Years of Innovation.

Ultra-Quiet Operation

Trilogy 45 is so quiet that you will hardly know it is running. The system is designed to operate slowly and consistently, unlike traditional air-source systems, which often feature noisy outdoor fans that disturb you and your neighbors.

Safety and Cleanliness

Geothermal systems use no flames to heat your home, so dangerous carbon monoxide and gas leaks are eliminated. The Trilogy 45 geothermal Series uses foil-faced insulation and a stainless steel drain pan for easy cleaning.

Breathe Easier with Superior Indoor Air Quality

The Trilogy 45 delivers superior air filtration for improved indoor air quality with MERV 11 filters and enhanced air exchange from extended run times.
