About Us

Spectrum Manufacturing is an independent manufacturer of geothermal heat pumps located near Spokane, Washington. Founded in 2008, Spectrum Manufacturing approached the design and manufacturing of their geothermal heat pumps with one goal- to satisfy dealers and homeowners. With this in mind, Spectrum Manufacturing built a geothermal heat pump in a class of its own.

Benefits of a Spectrum Geothermal Heating and Cooling System

Lower Operating Costs

A geothermal heat pump is 400 percent efficient, compared to a fossil fuel furnace which is only 80-90 percent efficient. Overall, a geothermal heating and cooling system can save you from 30-60 percent on annual energy costs. Cutting your utility bill in half can make a huge difference.

Low Maintenance

Geothermal heat pumps require little to no maintenance. When installed correctly, the geothermal ground loop lasts for generations, out of sight and out of mind. And since there are very few moving parts on the geothermal heat pump itself, maintenance comes down to occasionally changing the air filter.


A geothermal heat pump typically lasts for 25 – 30 years. Because there are very few moving parts, and because Spectrum geothermal heat pumps are built using stringent quality control guidelines, a geothermal heat pump will outlast any other heating and cooling system. In addition, the ground loop is guaranteed to last more than 50 years, giving you peace of mind in your investment.

More Attractive

Many heating and cooling systems require components located outside and around the building.  This can clutter the surrounding area, destroying the scenery. However, with geothermal, there is no equipment to clutter the area surrounding the building.

Control System

The control system inside the Spectrum geothermal heat pump is unmatched. The control system features a simple yet extremely reliable controller known as a PLC, (programmable logic controller). Proven in multiple industrial and commercial markets, this controller is unparalleled in flexibility and dependability. As the PLC is working, it displays the operations of the heat pump on an external screen- allowing for fast and easy monitoring and diagnosing.

Noiseless Operation

Spectrum Manufacturing has gone the extra mile in making sure that their units are the quietest on the market. The compressor is isolated twice using heavy duty rubber grommets. A specially designed compressor blanket muffles the noise of the compressor. In addition, the Spectrum geothermal heat pumps have a three-layer automotive grade insulation package. These factors make the Spectrum geothermal heat pump  the quietest on the market.

Residential or Commercial

Spectrum Manufacturing has a solution for all job requirements. Whether it is just a three ton residential job or a 30 ton system for a commercial building, Spectrum Manufacturing is there to provide an answer to any heating or cooling need.

Spectrum Manufacturing offers a full line of geothermal heat pumps for commercial and residential applications. We have water to water units, water to air units and we also manufacture our own hydronic fan coils.

Dealers who have installed these systems are truly impressed, saying they are very quiet and reliable, and customers are very happy with their purchase.

That is our mission.
