The gas furnace built for you!

Thermo Products, makers of Thermo Pride heating and cooling equipment, listens to homeowners and incorporates your needs and concerns into a line of premiere gas furnaces. You are ensured long-lasting trouble-free operation and peace of mind when you choose a Thermo Pride gas-fired furnace.

Traditional Craftsmanship - For over 70 years, the Thermo Pride name has stood for handcrafted products and hometown values. During this time we have never lost sight of our heritage, our goal of producing the highest quality comfort products, or our commitment to complete customer satisfaction. This has allowed us to provide customers like you with the highest quality products, which you deserve. Thermo Pride gas furnaces are designed in upflow (CLHS) and counterflow/horizontal (CDX3, CDB1) models. This ensures that you get the furnace that’s a perfect match for your home.

“Peace of Mind” Warranty - The proven longevity of Thermo Pride’s heat exchanger combined with the “Peace of Mind” warranties, help eliminate your risk and worry of having to repeat a substantial investment. The “Peace of Mind Plus” warranty provides that if the heat exchanger fails within 10 years from the date of installation, Thermo Products will provide you with a replacement furnace*. The “Peace of Mind” warranty covers the cost of defective parts for the first ten years and covers the heat exchanger for life. Should you sell your home, the warranties will also transfer automatically to the new homeowners.

Quality - Proven quality components, heavier construction throughout the appliance, and a cabinet that is designed to last are just a few quality features of Thermo Pride gas furnaces. All models are constructed with state-of-the-art components to operate under a variety of conditions while providing complete comfort.

Temperature Rise - Comfort is the purpose behind any heating system, and warmer air from the heat vents in your home means greater comfort for you. “Temperature rise” is the temperature difference between air entering and exiting the furnace. The higher the temperature rise - the greater the warmth of the air when it enters your home. Thermo Pride has set a standard of 70°F temperature rise across its full line of furnaces, considerably higher than other manufacturers' units. Offering quality, value and traditional craftsmanship, a Thermo Pride gas furnace is truly the gas furnace built for you.

When should I buy a Thermo Pride CDX3 series furnace?

The Premiere 2-stage 90%+ furnace (CDX3) has all of the benefits of the single stage 90%+ furnace (CDB1) plus a few added features.

  • Do you want to increase comfort and further reduce your fuel bills?

The high efficiency ECM variable speed blower motor will save a significant amount of electrical energy in applications that require long or constant blower operation.

  • Is improving your indoor air quality important to you?

The ECM motor will allow for reduced speed during constant fan operation for air filtration and improved indoor air quality.

The ECM variable speed blower motor adjusts to compensate for less than perfect duct applications and/or dirty filters (filters should be cleaned or replaced on a regular basis).

Two stages of heat allow for longer run times at a reduced firing rate. Increased run times allow better air filtration and reduce temperature swings during the milder seasons increasing your comfort level.
