Which type of heating system to install in my home Heat pump or gas furnace and ac unit?
That will depend on the cost (and availability) of gas in your area, when compared to electric costs. It will also depend on the climate. At very cold temperatures (below 40 F) the heat transfer element of an air/Freon heat pump does not deliver heat, and the less efficient electric heat kicks in. In a climate that has long periods of below-freezing temps, a gas furnace may be more economical to operate.

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.
Mechanical penetrations (Supply or Return Air Vents) are not allowed in garages in residential construction under the International Residential Code.. . Some countries' Buil…ding Codes and/or Regulations may allow a garage to be heated by a normal water-heated radiator supplied by the house's furnace or hot water calorifier. (Calorifier = "boiler" in everyday language.) . To find out if it is allowed where your home is situated you must check the Building Codes and/or Regulations for your locality i.e. Town/State/Country or - better still, as you needed to ask this question here - ask a locally-licensed plumber or HVAC (Heating Ventilation and Air Conditioning) technician for advice. . . Yes you can, as long as you use a 1 way trap tha restricts the airflow only to the garage and not backwards. "International building codes" do not apply everywhere
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 t…o 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.
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 winte…rs 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. Best to get your appliances properly sized for your situation and climate. It sounds as if you`ve already been burned once with guesstimates.
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 b…urners to exhaust out through the furnace flue. The outside of the heat exchanger is where the cold air passes over, becomes 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.
Yes, not a problem.
need to change condensing units. from cooling only to heat pump
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, w…all-mounted, etc.). If the furnace already has a thermostat installed then it is just a matter of replacing the existing thermostat 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.
Could be lots of things. If you have a standing pilot light, one that stays on all the time, the thermocouple may be bad. A thermocouple is a small rod that sits in the flame …of the pilot light. It then runs to the gas valve. This produces a small amount of electricity that keeps the valve open to let the gas in. If the pilot light goes out it shuts the valve so the house doesn't blow up. Easy enough to replace. If the pilot light is still on and the furnace will not light, it has to be the thermocouple. Check fuses at the furnace and in the panel. Newer gas furnaces have a circuit board in them that can go bad. There are a dozen things that could keep it from working, it is just a process of elination.
Your location matters. If in Florida heat pump in more northern climes furnace & ac.
Homes are heated with natural gas, also known as methane.
It's easier than you think. First, turn off the breaker to the furnace. Then remove the thermostat from the wall, paying close attention to which wires are hooked to what term…inals. The terminals are labeled with letters, and are about 99% universal in the industry. They are most likely color coded(R=red, Y=yellow...)But just make sure you re-wire the same way it was before, so you furnace is getting the same imput as the old stat. If you have wires or terminals that don't match up go ahead and schedule a service call, but definitely try it first. It can be as easy as 4 color coded wires.
Could be a few things, the house being cold, a broken temp sensor, disconnect between the sensor and the furnace/pump.
Rule of thumb is 500sf per ton. 1500sf = 3 ton
