When the term "furnace" is used within the context of heating a house, it's assumed to be a "forced-air" furnace, not a blast-furnace or other type. The forced-air furnaces all heat in the same method: by sucking in air, heating it, and blowing it out. Thus, furnaces heat your home by heating the air inside it. There are 4 major types of furnaces: gas (natural gas & liquid propane), oil, electric, and solid fuel (wood, wood pellets, corn, coal, etc...).

quot;oversized" furnace will warm up the house quicker, but it will use more fuel and there will be greater temperature swings in your home. A smaller furnace will maintain more even temperatures, use less fuel, but will take longer to raise the temperature. McCullough Heating & Air Conditioning will calculate the proper furnace size to maintain 80 degrees inside when it is zero degrees outside. [ back to top ] See similar questions...

YES! Our unit works with or on any typical upflow, downflow, or horizontal forced air furnace as well as heat pumps! See similar questions...

Yes. Currently Video Furnace supports OS X as described elsewhere in this FAQ regarding minimum platform requirements. Yes, Video Furnace supports RH Linux 7.3 and 8.0 in X/Windows with OpenGL. See platform requirements in another part of this FAQ. With Linux, the first request to watch IP video may ask that you accept and install the appropriate Java plugin. Figures 1 ??? 5 show the popup messages displayed during installation of the appropriate Java run-time environment. See similar questions...

A heating unit that heats air by transferring heat in a metal combustion area to the air and circulating it through the house in a network of ducts. The common fuels used to heat the air circulated through the furnace are fuel oil, natural gas, and electricity. Furnaces may need to be replaced if the heat exchanger cracks or if the homeowner wants to upgrade to achieve higher fuel efficiencies and save money on heating bills. An air conditioning system can normally be added to a furnace. See similar questions...

Air filters in your furnace/air conditioning system were originally designed to help keep the equipment clean. But as we have sealed our houses from air infiltration so as to conserve on energy used, we have enveloped ourselves inside an environment that is continuously off-gassing gases and shedding airborne particles. Thus there is a need for better filtration to protect us from the air that we breathe. Your air ducts can be a breeding ground for germs, bacteria, mold and mildew. See similar questions...

No. moisture will NOT condense on your filter as long as your filter is not severely clogged and dramatically restricting air flow. The Desert Spring furnace humidifier is a passive evaporative device. Therefore the air passing through the unit will only carry as much moisture as it can hold. Similarly, the moisture will not condense in your duct work. Steam or atomizing humidifiers can cause these problems, but not a passive by-pass humidifier like the Desert Spring.

Answer: That depends on what type of furnace you have. If you have a warm air furnace then you have an air filter. If you have a boiler and radiators then you probably don't have air filters. See similar questions...

During the summer, dust particles build up on the heat exchanger. When fall comes, you start your furnace, and the heat exchanger heats up to approximately 200 degrees Fahrenheit. Every time the furnace begins operating, the dust and dirt that built up all summer long begins to burn the dust off, which is the smell that is coming from your furnace. See similar questions...

McCullough’s comfort consultant will measure your home and calculate the actual heating & cooling load on the home (calculation using Manual J v8 that incorporates information about window size & direction, walls, ceiling, floor, appliances, insulation, etc). This will determine the proper size of equipment and ductwork that is needed. This will be compared to your current equipment & ductwork and will be adjusted based on your lifestyle, etc. See similar questions...

Generally allow one day for replacing a heating and air conditioning system. Installing a brand new central heating and cooling system, including ductwork , may take two days. Be aware that reputable contractors will refuse to install a new air conditioning system or heat pump system when it is raining. This is due to the fact that when moisture gets inside refrigerant lines it can be very damaging and can cause reliability and maintenance issues. [ back to top ] See similar questions...
