Gas bill Leaving you Cold ? We can help.

If your furnace is over 12 Years old, chances are replacing it will reduce your heating costs by at least 30%. It can also help improve your comfort, health and safety. To get the perfect combination of balanced comfort and energy savings, call Thermocool to schedule a time for one of our comfort advisors to conduct a comfort analysis, and to design the size and style of furnace that will work best for your home or business.

Warm air heating is the most common, dependable and economical source of heating comfort for your home or business. A warm air furnace is typically fired by fossil fuels such as natural gas, fuel oil, propane and electricity and distributes that heat transfer by a fan which is connected to a ducted distribution system.

When your thermostat has a call for heat, it communicates this signal to your furnace. The burners come on, and in some cases also a combustion blower depending on your brand of furnace and efficiency of your furnace, as it heats up the combustion chamber inside the furnace. The blower or circulation fan starts to operate. As the fan is operating, it will pull in air from your conditioned space by the return/cold air duct distribution system. This air will now pass by and around the combustion chamber picking up (heat transfer) and supplying the hot/warmer air through the supply/hot air duct distribution system back to the conditioned space. This cycle will continue until the thermostat is satisfied or desired temperature has been reached.

Each and every structure should have a survey of its elevation, square footage, square foot of windows and doors and exposure to determine the correct load size or amount of heating capacity that is required. This survey is also known as the Manual J Load calculation.

AFUE means “Annual Fuel Usage Estimate” or efficiency.

80% AFUE means that 80% of the fuel burned by an appliance is providing heat to the conditioned space. The remaining 20% is venting through the chimney and heating the outside.

By installing a furnace with a rating of 98% AFUE now 98% of your heating dollars is actually heating your conditioned space, and only 2% is lost to the outside.

80% AFUE warm air furnaces have different features and options which can be installed in multiple positions and locations depending on construction of the structure. These furnaces require a chimney or metal flue for venting. 80% warm air furnace is a fan-assisted appliance which utilizes a small fan, or inducer motor, to pull combustion air (air from inside the conditioned space) into the combustion chamber and force exhaust gas out into the flue.

90% AFUE or better warm air furnaces have different features and options which can also be installed in multiple positions and locations, but the venting and combustion process are different. Theses furnaces are direct-vent appliances which means that both the exhaust and intake air (combustion air) are piped directly to the outside. No combustion air is utilized from the conditioned space, which can help lower the amount of unwanted infiltration (drafts) in a building. The combustion chambers are sealed for better control of the combustion process. 90% warm air furnaces are also known as condensing furnaces. A condensing furnace recovers waste heat from the exhaust gases, which would normally vent to the outside, but now are captured in a secondary heat exchanger that pulls heat from water vapor being produced during the combustion process.
