Yes the same way you pump down a a/c, shut off unit at stat, remove electronics housing compartment door, place gages on service ports and close the liquid side service valve using your service wrench , then almost shut the suction side . keep it about a half of turn open. press in contactor and monitor gages till almost all pressure is gone then quickly close valve the rest of the way. newer unit have a low pressure switch in them making this difficult with out leaving ref in system as they cut out at around 50 psi. barring this you must recover ref into bottles

Heat pumps do work on a refrigerant to reverse the normal flow of?
Heat (or thermal energy).
What are heat pumps used for?
A heat pump is a central air conditioner that uses a reversing switch to operate in reverse; the way the air conditioner works in the summer. If you went to the big fan unit (condenser) outside your house during the summer, you would notice, it blows hot air from the fan . Heat pumps are used to produce heat for residential housing, economically, by absorbing temperate winter air, and using it to heat your house. Heat pumps can usually maintain heat in your house down to about 20 degrees Fahrenheit, until you would need to use another source to heat your house. Heat pumps are mostly used in the Southern parts of the United States, where the winters are mild, Heat pumps can be economically used in other parts of the United States where average temperature during the winter may not go below the 20 degrees, disused earlier, and the break-over price for fuel cost using the main furnace. Usually, propane gas, verses running the electricity for the heat pump is more economical. To find out if a heat pump would work for your situation. Contact a qualified hvac contractor to perform an energy survey of your residence.
How is passive and active solar heating systems different from one another?
a passive solar system converts sunlight into thermal energy without using pumps or fans and active solar system captures the suns energy then uses fans and pumps to distribute the heat
What are the advantages of having an under floor heating system?
There are many advantages to having an underfloor heating system. The main advantages are their ability to work with heat pumps, and their no maintenance set up.
What metering device is the most efficient for heat pumps?
Thermostatic Expansion Valve (TXV, TEV). Any high efficient system requires one.

What are inground heat pumps?
GEO - thermal system.
What system uses compression pumps and condensers to the cool air?
Heat pumps use compression pumps and condensers to cool air.
What is the worst rated heat pumps?

Does heat pumps need Freon to blow heat out?
Yes, the heat pump (in the heating mode) is like an air conditioner in reverse. It cools the outside air and heats the room air. Of course, you need Freon to do this heat-transfer process.

What heat are pumps?
A better way to heat and cool your home - but it may be expensive in the git go. Heat pumps have a problem heating with temperatures below 35 degrees. They can't provide heat if it is below 35 degrees outside. Pipes are laid under ground to use the 55 degree amibent heat there and the heater with 55 degree coolant, the heat is extacted by the heatpump to warm your house. They can also work in the reverse to cool homes. Acting similar to a refrigerator, heat pumps can draw heat from the home and transfer it into the ground and tamp into the cooler ground temperature.
Understanding The Geothermal Heat Pump?
Conventional heat pumps heat homes and buildings by extracting heat from the outside air. In summer months, heat pumps function as air conditioners by reversing the process. Unfortunately, heat pumps are trying to provide heat when the air is coldest outside and to cool when the air is hottest. Thus, in very cold and very hot weather, conventional heat pumps do not operate efficiently.The Geothermal Heat PumpGeothermal heat pumps offer another solution to heat and cool homes and commercial buildings. Instead of exchanging heat with air, these heat pumps exchange heat with the ground or a source of water. This gives geothermal heat pumps a significant efficiency advantage over conventional heat pumps because the ground and water sources are more thermally inert than air. What this means is that the ground below the frost line and bodies of water do not change temperature much no matter what the season. So geothermal heat pumps do not have to work as hard to heat in the winter and cool in the summer as conventional heat pumps do. Consequently, they use significantly less electricity than conventional heat pumps and have less need for auxiliary heating sources. There are two types of geothermal heat pumps. The closed system uses a mix of water and antifreeze that flows through pipes buried in the ground or submerged in a large body of water such as a pond or lake. The open loop system pumps water from a well, pond, or lake through the heat pump and then pumps the water back to the source or to a drainage ditch.Factors to ConsiderGeothermal heat pumps are more efficient than conventional heat pumps, but that efficiency advantage varies greatly. A consumer may see as little as a 20% gain over his current energy source, or he may see in excess of 60% gains in efficiency. Factors such as the local geology, availability of a water source, the type of geothermal heat pump installed, and the cost of the type of energy currently used impact the efficiency gains. Geothermal heat pumps also cost twice as much or more than conventional heat pumps to purchase and install. However, they cost less to maintain and usually have a longer lifespan than conventional heat pumps. Home and business owners should do significant research and seek expert assistance before determining which type of heat pump is right for them.

Quality of Trande Products?
Yes. Trane is one of the best heat pump manufacturers. They produce high quality products. You can buy their heat pumps. They won't wear down or break down easily.
Do heat pumps bring fresh air in the house?
Not unless you have a fresh air duct connected to the return air system.
