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:The igniter, flame sensor and high-limit switch are the parts of a furnace that can be replaced. Other replaceable furnace parts include the mounting bracket, fan blade, control board, capacitor and drain pan.
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: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:Troubleshoot heating problems at home by determining the cause, such as a thermostat merely being set at too low a temperature, by the problem, which is that the furnace does not put out enough heat. The solution is to raise the thermostat settings to a comfortable temperature.
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: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: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: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: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:The exact method depends on the thermostat, but most programmable thermostats have a reset switch or button. This is often located below the main panel of the thermostat or on the side where it is difficult to press by accident.
A:The amount of energy used to air condition a building depends on the size and layout of the building and the air conditioner's seasonal energy efficiency rating. A licensed heating and air conditioning contractor can estimate how much energy a given system uses to cool a given building.
A:Troubleshooting an air conditioner starts with making sure the thermostat is powered on and connected by setting the system to cooling mode and turning the fan on. If this fails, the power cable and circuit breaker should be inspected.
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:Fans do not typically cause the temperature in a room to drop. It is possible to use a fan to create a wind-chill cooling effect under certain circumstances. A person without air conditioning may only circulate hot air when setting a fan in the center of a warm room.
A:According to the U.S. government's Energy Star website, about half a home's energy bill goes to heating and cooling, so one way to cut down on electric bills is to ensure heating and cooling equipment work efficiently and to seal the house to avoid temperature leakage. Other ways to cut down on electricity include using hot water sparingly, upgrading to energy-efficient appliances and turning off lights when not in use.
A:Gas heaters of all types need access to a gas line, which often leads to higher installation costs. Gas heating units are often more expensive than their electrical counterparts, but they may cost less to run.
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: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.
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.
