Answer . Yes, the thermostat in your home causes the gas valve to come on inside the furnace, although in some of the newer, high efficiency furnaces the process is a little more complicated. Furnaces usually detect the temprature inside the plenum and turn on the blower to move warm air into the… home. Once the home is up to temperature, the gas is shut off and the blower will run until the plenum is cooled.. Answer . The gas should not go off and on until it reaches the desired temperature.\n. \nThe gas should come on and the burners should stay lit until the desired temperature is reached. If this is not the case and the burners come on and off, you have a problem. If the burners come on and stay on until the temp set on your thermostat is reached then all is well. \n. \nIf you notice your burners are not lit and the temp is not reached and the blower is on, then you have a problem that needs a service tech. Your filter could be clogged or your flue pipe could be blocked or there may be a problem with your high limit. (MORE)
Answer . \nUnless there is an access hole in the rear area of vehicle you have to drop the fuel tank- there is access at the top of the tank for replacement
Answer . This is not a job for the home fix-er-upper type. There are special tools required, and special training and Federal/EPA training and testing required for refrigerant recovering and recycling. Assuming, then, that you had all of this covered, you would: make the unit safe, disable an…d lockout the electrical power supply, Pull the refrigerant out of the system and store for later recycling, verify there is no pressure in the system, cut the pipes with a tube cutter leading to the compressor. Remove the power leads to the compressor. Remove the compressor. Mount the new compressor, Fit up new copper pipes and solder them in with a nitrogen purge and limited flux. Connect the power leads. Put a deep vacuum on the system and check for leaks. Charge the system with the correct number of pounds/ounces of refrigerant. Start the system and test run, checking the system pressures with guages to verify proper operation. Put all the panels back on, (with ALL the screws). (MORE)
We have central heat and air. Does the furnace blower unit power on for the AC system too or is there a separate blower?
Answer . There should be only one blower to move the air. The unit will have a coil for cooling and a heat exchanger.
Depends on if one is there already. If not better get a contractor.. You might also consider buying a guide. There are several furnace installation guides on the internet. Coupled with the installation instructions that the manufacturer gives you it should not be a Hugh problem. I do not know if I …am allowed to post one that I wrote but its at www.furnacebook.com . I guess it will get edited if not allowed. (MORE)
An AC unit isn't supposed to heat! If you mean a heat pump, then you may have a relay switch problem. Or maybe, your thermostat is in the cooling mode. Contact a repairman.
The energy source is the same as for heating anything. Gas,Electricity, Burning any fossil fuel. in a boiler (furnace) with water running in heat exchanging coils or manifolds. When heat is needed a pump circulates the hot water through the radiators and back to the furness.
\nNot unless your unit has air flow drop sensors that could damage the pumps. If you installed a new filter and the furnace then quit maybe you didn't properly replace the door. There may be a switch attached to the door or filter. Look fer it!
Hi, Good question and the answer is ( YES! ) as long
In cgs units, one erg is 1 g cm 2 s â2 , equal to 1.0Ã10 â7 J. The imperial /U.S. units for both energy and work include the foot-pound force (1.3558 J), the British thermal unit (Btu) which has various values in the region of 1055 J, and the horsepower-hour (2.6845 MJ). The energy… unit used for everyday electricity , particularly for utility bills, is the kilowatt-hour (kWh), and one kWh is equivalent to 3.6Ã10 6 J (3600 kJ or 3.6 MJ). Electricity usage is often given in units of kilowatt-hours per year (kWh/yr). This is actually a measurement of average power consumption, i.e., the average rate at which energy is transferred. The calorie equals the amount of thermal energy necessary to raise the temperature of one gram of water by 1 Celsius degree, at a pressure of 1 atm. For thermochemistry a calorie of 4.184 J is used, but other calories have also been defined, such as the International Steam Table calorie of 4.1868 J. Food energy is measured in large calories or kilocalories, often simply written capitalized as "Calories" (= 10 3 calories). In physics and chemistry, it is still common to measure energy on the atomic scale in the non-SI, but convenient, units electronvolts (eV). The Hartree (the atomic unit of energy) is commonly used in calculations. Historically Rydberg units have been used. In spectroscopy and related fields it is common to measure energy levels in units of reciprocal centimetres. These units (cm â1 ) are strictly speaking not energy units but units proportional to energies, with hc being the proportionality constant. (MORE)
No, gas is the best heating fuel if you consider price. The only exeption is, are you building a new structure or changing the heat system in an exsisting structure and have to consider new line overages. New gas service is normally installed by the gas provider at a minimal cost unless the distance… from the main is over a certain distance. Call you service provider for this information. (MORE)
All the heat pumps that I know of are electric. Some may have gas backup-- in very cold conditions , heat pump will not work, so some kind of backup is needed.
When operating a high efficiency nat gas forced air furnace and heat pump at what cost ratio or percent of gas therms to kilowatt hours does it make more sense to use the high efficiency furnace only?
There are 3413 btu per kWh and 100,000 btu per therm of natural gas, these are constants. In order to give a correct answer the exact efficiency rating of the high efficiency furnace and the energy costs per kWh and therms would need to be known.

Can a 3ton heat pump make up for an undersize ac unit and inefficient furnace for a 2000sqft 2story home?
Any air cooled heat pump is only effective down to around 35*F outdoor temperature. So your climate has something to do with what you are asking. In some areas with mild winters possibly yes. But on the other hand since your heat pump will also be providing your cooling, 3 tons sounds a bit light to… me for a two story 2000sf home.

NO! the compressor has oil in the crankcase similar to a car. The compressor relies on among other things gravity to return the oil back. There are window shakers out there that will fit your application, just not this one.
The process of pumping down a heat pump is quite simple. First you should switch the unit into air conditioning and put your compound gauge on the suction line. Make sure the unit is running. Then valve off the discharge line and watch your gauge pressure. When it pulls itself down into a vacuum the… heat pump is pumped down within itself. Make sure to valve off the suction line to make sure no refrigerant is released back into the air handling unit. You should now be able to lay some wet rags on the valves to protect them if you desire to sweat the unit away from the line set. (MORE)
The heat exchanger is the metal wall or tubing that is heated up when the burners are ignited. The inside of the heat exchanger allows the toxic flue gases produced from the burners to exhaust out through the furnace flue. The outside of the heat exchanger is where the cold air passes over, beco…mes warmed, and is blown throughout the ductwork of the home. The heat exchanger is the only wall separating the toxic flue gases from the supply air. If a crack develops in the heat exchanger, there is a potential for carbon monoxide gas to leak over to the supply side and be blown throughout your rooms. Carbon monoxide gas is odorless. The human senses will not detect its presence. . Ron Ferrara- DHR Mechanical Services, Inc. (MORE)
How can i find how much it cost to run a air heat pump in central Illinois compared to a gas furnace?
Find out what you pay per kWh, then determine the wattage used per hour of run time of the heat pump. Then multiply the two for cost of runtime per hour. Do the same with your cost per therm (100 cubic feet of natural gas). Determine the input rate of the furnace in btu per hour (100,000 btu input w…ould equal 1 therm used per hour of runtime). Multiply the two and you have your cost per hour of runtime. For example: at $ 1.00 per therm cost and an input rate of 80,000 btu or .8 therms, you would have a cost of $.80 per hour of runtime with natural gas. With a cost of 11 cents per kWh and a system that uses 15 amps, 15 amps x 230 volts = 3450 watts or 3.45kW, multiply that times .11 cents and your cost per hour of runtime is .38 cents. Lastly don`t forget to add in the wattage per hour of the electric strip heater you will need to go with the heat pump. Don`t worry about the power consumption of the indoor fan because you will need that to operate either one. Regardless of how the cost works out for you, I personally would not entertain using a heat pump in your climate. (MORE)
I am assuming that by asking about a "heating thermostat" for a "furnace" we are not talking about air conditioning/heating units or about electric heating units (baseboard, wall-mounted, etc.). If the furnace already has a thermostat installed then it is just a matter of replacing the existing the…rmostat with a new one. Heat-only thermostats can be obtained from home centers such as Lowes or Home Depot. They should be specified to work on 24-volt circuits, unlike those designed for 110/220 volt AC electric heaters. Replacement is simply a matter of removing the thermostat cover, detatching it from the wall, and disconnecting the two wires from the old unit. Connect the wires to the new thermostat and mount it to the wall in place of the old one. Be aware that some thermostats must be adjusted level to work properly - read the enclosed literature that comes with the new unit. If this is a new or replacement furnace that has never had a thermostat connected then there are several additional considerations. You will need to identify a location for the thermostat. This location should be on an interior wall, out of any drafts, and in a location such as a hallway which is an "average" of surrounding rooms. You will have to run 2-conductor thermostat wire (available at home centers) from the furnace to the thermostat. Connections to the thermostat are as outlined above. The connections at the furnace end depend on the type of furnace - passive hot air, forced hot air, passive hot water, circulator-driven hot water, steam, etc. These variations are beyond the scope of this general question.

That depends on what the cost for each particular fuel is in your area and the btu yield of each. Example: 1 gallon # 2 fuel oil yields 140,000 btu and 1 kW=3413 btu. So you would compare the cost of 41 kW vs 1 gallon fuel oil. Plus you need to add the kW usage of the electric auxilliary strip heate…r you`ll need with the HP into that cost. Plus if you live in a colder climate, most of the time you will be running on the strip anyway which is far worse than oil. HP`s are not usually effective below 35*F or so outdoor temp and for that reason if you are in a northern climate you should not consider it. But that is just my opinion. (MORE)
That is the function of the thermostat. There are Auto and Manual changeover models made. Since you asked this question you must have an Auto changeover model.
That will depend on the cost (and availability) of gas in yourarea, when compared to electric costs. It will also depend on theclimate. At very cold temperatures (below 40 F) the heat transferelement of an air/Freon heat pump does not deliver heat, and theless efficient electric heat kicks in. In a …climate that has longperiods of below-freezing temps, a gas furnace may be moreeconomical to operate. (MORE)
A heat pump is one part, of a two part heating and cooling system and can be used as the primary heating unit in mild winter locations. They can also be used to supplement other heating systems where the temperatures are sub-freezing for longer time periods. Heat pumps also are used in summer for co…oling. Basically, the way the system works in cooling mode is the same as most any other AC system. When winter comes it essentially runs the system in reverse to produce heat instead of cooling. The advantage is that it is very cheap to run. The biggest two disadvantages are the compressor has to run during both seasons, causing wear... and ... after you get to about 26 degrees F., the heat pump needs auxiliary heat (gas or electric coil) to warm your house. For most warmer climates they are the best choice. Speak with an HVAC professional to determine your region's best heating option. (MORE)
A heat pump pulls the air back through and recylces it to make heat. A heat strip is just air being pushed across the heat strip to make the air warm.
The hot water may be turned off to them or the valves could be clogged. Rust and sediment build up over time and stop the flow.

How can I get my furnace fan to move more air. We had a new ac unit installed the HVAC tech said our ducting is too big for the house. You can barely feel air coming out?
I am continuing my question because they'll only allow it to be so long. Our house is only 1300 square feet but we live in a cookie cutter development where there are other houses 2600 square feet. So perhaps the contractor ordered one size ducting for all houses. I've been in the crawl space and at…tic inspecting the ducting for leaks with the fan on and have found none. The furnace does fine in the winter when it's heating though here in Western Washington it doesn't get that cold. I replace the filter about ever 3 months and have installed an attic fan to help out. However the AC never seems to keep up even when its only 75 degrees. Thank you. (MORE)

Why doesnt the outside unit Goodman CPLE36-1 central AC unit with heat pump turn on but inside the air blows though it's not cooled and the heat only works on emergency heat?
I would first try to turn the stat up to 80 degrees turn off both breakers, one to the outside condenser and the other to the air handler inside, leave the breakers off for about 30 minutes. then turn the breaker to the out side unit first then 5 minutes later turn on the breaker for the inside unit…. Wait another 5 minutes and turn the stat to 68 and wait a few minutes system should reset and work like it should. If that don't work I would say the starter capacitor is bad. Or the compressor is bad. Or may need to refill the lines. If the first don't work it is time to call a repair man. Hope it works Sincerly Troy H (MORE)
The compressors are basically the same . Very simply put with out getting to technical is what makes a heat pump a heat pump is a reversing valve that changes the direction the refrigerant travels in lines leading to and from the condensing unit and to the coil, without changing direction of flow in… they compressor.

Cost may vary depends on the house size, accessibility, the amount of work involved in duct reworking, disconnecting/connecting gas electricity.

No, just find someone to install it "on the side". You will be able to get it installed for 1/2 the price
If no major duct work involved, the price range is about $1,500 ~ $2,000 for basic models. If you want high efficiency and variable speed, it can easily cost you up to $3,000.

Could be a few things, the house being cold, a broken temp sensor, disconnect between the sensor and the furnace/pump.

Normally an AC unit does not have a vacuum pump in it. It does have a compressor - but the vac pump is a tool for installation. Once you have an air tight network of pipes connecting the indoor and the outdoor units you want to get all the moisture and air out of the system. (The under lieing princi…ples apply to automotive AC as well) The method is to use the vacuum pump to suck the contents out - then refill with inert nitrogen, and rinse and repeat several times to effectively flush any particles of moisture or air out of the system. The tool which allows you to do this is a manifold gauge, it's critical when installing AC systems to remove all air and moisture from the pipes and not allowing any to get back in when you disconnect the schreader valve, so you have to disconnect after the refrigerant has been released into the pipework. If the refrigerant is R410a then when standing it could be at 10 bar pressure, so the best practice is to connect on the low pressure side of the system then run the system and disconnect with it running - so the pressure on the schreader is only about 7 bar. Installing split air conditioning systems should only be done by a trained and competent person though. In the UK there are specific rules about which qualifications are required to do this. (MORE)
