BTU is an abbreviation for British Thermal Unit, which is the international measure of energy. An air conditioner's BTU must be matched to the size of the room for adequate cooling. BTU tables estimate different energy requirements.
A:Repair a swamp cooler by replacing defective parts, such as blower motors, floats, pumps and evaporative pads. In areas where swamp coolers are common, most home improvement stores carry these parts. Swamp coolers are simple cooling devices and most owners can make repairs easily.
A:A good temperature to set the thermostat to during the summertime is 78 degrees Fahrenheit. It is recommended that electricity consumers set the thermostat temperature to 85 degrees when they are away from home.
A:Determining the appropriate size for an air conditioner ensures proper and effective function. If the unit is too large, it cools the room but doesn't properly remove humidity, resulting in a damp or clammy feeling. Conversely, a unit that is too small doesn't sufficiently cool the room.
A:A pilot light flame stops burning if the thermocouple is damaged or misaligned. The thermocouple is a piece of wire placed near the pilot light flame that detects heat. If no heat is detected, the pilot closes the gas valve to prevent unburned fuel from entering the home.
A:The average furnace lasts 15 to 20 years. This life span is typical of a furnace with a stainless or aluminized steel heat exchanger. In contrast, old furnaces with heavy metal heat exchangers last for 30 to 40 years, but they are less efficient than newer models, prompting many homeowners to replace them even if they still work.
A:Use the area of a room to determine the proper air conditioner size estimate, which is measured in British thermal units per hour. A 100- to 150-square-foot room needs a 5,000 BTU per hour unit, while a 400- to 450-square-foot room needs a 10,000 BTU per hour unit.
A:If an air conditioner is not cooling as well as it once was, it may need Freon. Some signs of this include the air conditioner being turned up to the highest setting, but barely producing any cold air, or cold air not coming out at all. Another sign is if large amounts of water are leaking from the air conditioner's air handler.
A:Replacement parts for small window air conditioners can be purchased online from home improvement stores such as The Home Depot as well as from parts suppliers such as Universal Appliance Parts and Zoro. Discount department stores with appliance sections such as Sears also sell many parts for small air conditioners.
A:Thermostats vary by design, but digital thermostats typically have both the current temperature and the target temperature. Traditional thermostats generally have a knob or lever attached to a marker that points to the desired temperature.
A:Conserving non-renewable fossil fuels by utilizing the earth's natural, renewable resources is one of the major advantages of alternative energy use. Using renewable energy sources is cost effective as well as environmentally friendly.
A:Kerosene and diesel are made up of long, flammable hydrocarbon molecules derived from crude oil, which is also known as petroleum. Kerosene is made up of a mixture of carbon chains with between six and 16 carbon atoms per chain. Diesel fuels are heavier, with anywhere from eight to 21 carbon atoms per chain. Both are liquid at room temperature, but diesel fuel has a higher boiling point.
A:BTU is an abbreviation for British Thermal Unit, which is the international measure of energy. An air conditioner's BTU must be matched to the size of the room for adequate cooling. BTU tables estimate different energy requirements.
A:Depending on the level of damage found, removing and replacing the air conditioner cord plug head is the best way to repair the cord on an AC window unit. Power cords with multiple tears and cuts in the rubber casing or damaged electrical wires should be replaced instead of repaired.
A:A variety of external elements can cause a false alarm from a standard ionization smoke detector. Loss of power, humidity, dust, insects and debris from common household appliances can all cause a false alarm.
A:Several different issues cause a central heating system to stop working. For instance, when the power is out, most systems no longer provide heat. Even though a forced air system uses natural gas as fuel, it may require electricity to operate the blower. If too many lights and electronics are on in the house, power overload can trip the electrical circuit breakers and affect the central heating system.
A:A typical ceiling fan uses 60 to 75 watts of energy per hour even when running on high. This makes ceiling fans a very efficient alternative to a typical central air conditioning unit, which uses 3,500 watts.
A:As of 2014, a building owner can expect to pay between $5,000 and $11,000 to replace the residential HVAC system. The cost of replacing an HVAC system varies greatly. The type of system, installation costs and any necessary changes or modifications to the structure can dramatically affect the cost of replacing the HVAC system.
A:Generally speaking, thermostats work by using a mercury switch that is in contact with a thermometer wire to trigger a temperature-adjustment lever in response to the expansion or contraction of the wires as they are heated or cooled. The expansion and contraction of these wires triggers switch relays that control heating and cooling by triggering either a circulation fan and heater or air conditioner.
