Tetco Heat Pump Features

Each TETCO heat pump is built to last with the high efficiencies for incredible comfort and cost-savings. Wondering what goes into each geothermal unit? Each of the below features is included on almost every one of our units, making them a cutting-edge, uncompromising geothermal solution.

Available Sizes

The size of the system required for home and buildings depends on the size of the conditioned space, insulation values, window type, etc. TETCO units come in a variety of sizes, and are appropriate for small homes and multi-ton applications.


The safety features of TETCO units include microprocessor controls that function to protect the unit if something were to happen. Safety is also taken into account throughout the lifetime of a TETCO Geothermal System. Our products are ETL certified to UL and CSA standards.

Hot Water Assist

Most TETCO geothermal heat pumps come standard with hot water assist. The unit will use excess heat to assist with heating a home or building's hot water, resulting in 25% - 40% savings on water heating costs annually.


All of our geothermal systems are ENERGY STAR certified, qualifying them for many incentives. Geothermal heat pumps cooling efficiency is rated by Energy Efficiency Ratio (EER) and heating efficiency is measured by Coefficient of Performance (COP). TETCO units meet or exceed all federal minimums for EER and COP. Additionally, TETCO Geothermal Systems are AHRI certified to ISO standards, which means they meet further high efficiency standards and are produced in an environmentally-conscious manner.

All-Aluminum Microchannel Air Coil

Many of our American-made geothermal heat pumps come standard with an all-aluminum Microchannel Air Coil. This improves heat transfer for increased efficiencies and lower operating costs, helps increase the system's lifespan, and enhanced structural integrity means less chance of damaging the coil during basic maintenance. 

Variable-Speed Fan

A variable speed fan provides the ultimate in comfort, allowing the fan to adjust based upon compressor speed, and evening humidity levels while cooling. In addition, for homes where constant fan (continuous air circulation) is beneficial, a variable speed fan operates at a much lower speed, which provides circulation and filtration at a significantly reduced sound level.

Heavy Gauge Steel

TETCO geothermal systems are built to last with heavy gauge steel. The panels can be easily removed for installation and maintenance.

UL GREENGUARD Gold Certified Cabinet Insulation

TETCO’s exclusive UL GREENGUARD Gold certified cabinet insulation allows the unit to operate quietly, so as to never disturb your comfort.

Compressor Type

TETCO geothermal systems are built with variable-speed, two-stage, or single-stage compressors. This allows our product line to cover a wide array of applications, system demands, and budget constraints.

Temperature Sensors

As part of the safeties that come standard with TETCO geothermal systems, an air coil temperature sensor protects the system in the event the filter is blocked or the fan motor stops working. Additionally, with the ES6V, an outdoor ambient sensor provides temperature feedback, enabling the unit to use the lowest possible water temperatures; this eliminates temperature swings and noticeably increases your space's comfort.
