Furnaces and Heat Pumps

Furnaces and Heat Pumps in Weld County

The evolution of furnaces has been significant over the years. Conventional furnaces exhausted combustion gases fast and hot so they would exit the chimney flue before cooling and condensing. The furnace heat exchanger would not as efficiently collect as much heat from the fuel combustion process as possible. Condensing furnaces have the ability to capture some heat even after the combustion exhaust gases have cooled and condensed. This is accomplished by utilizing two heat exchangers, one designed for primary heat exchange and one to handle condensed exhaust gases consisting of water and carbon dioxide. The exhaust gases are depleted of a portion of their heat until the condensate drips out of the heat exchanger and the flue gases exit from a plastic PVC pipe instead of a chimney.

A-1 Heating and Air Conditioning

There are three types of furnaces recommended today:

where the burner and blower have one “on” stage. Available in 80% efficient and high-efficient furnaces.

burner flame and burner to operate on a high and low setting depending on how much heat is required. Available in 80% and high-efficient furnaces.

controls for the burner and blower motor to allow fine-tuned adjustments to the burner setting and blower motor speed, and modulates them to keep the temperature of the room, closest to the thermostat setting. Available in high-efficient furnaces only.

Furnace Efficiency Ratings

The annual fuel utilization efficiency (AFUE) is a thermal efficiency measure of combustion equipment such as furnaces, boilers, and water heaters. AFUE measures the amount of fuel converted to heat in the space, in proportion to the amount of fuel entering the furnace. The higher the AFUE rating, the more efficient the furnace is

Efficiency categories can be organized as follows:
