Although most economical and efficient option of heating and cooling, Geothermal heat pumps installations can go awfully wrong if your HVAC technician is inexperienced and not 
qualified enough. Here are the five most common mistakes with your Geothermal heat pumps you can avoid.
Proper sizing of your Geothermal Heat Pump
Most of the times, over sized heat pump remains the issue particularly when your HVAC technician in inexperienced. To negate his inexperience, he considers a comparatively large safety factor often resulting into over sizing equipment. Not only such heat pumps consume more energy, their functions lead to short cycling which ultimately results into considerable temperature variation and quick wearing down the instrument itself. Always ask for proper load calculation based on ACCA Manual (J).
Proper distribution system
Although all geothermal systems wonk on the principle of drawing thermal energy from ground, heat distribution system varies greatly according to its type. Here, duct work plays a key role in effective functioning of your HVAC system. Whether its radiant system or forced air duct system, they should be designed in appropriate manner. Always follow ACCA Manual (D) for residential heat pumps.
Selection of appropriate type of circulator pump
The circulator pump is the one responsible in moving water from the ground and then into the heat pump. This circulator pump should have required power to overcome friction from the fittings, piping and fittings and the pressure drop. A good Las Vegas Air Conditioning repair contractor will select a pump based on a power of specific heat pump and head loss calculation.
Correct sizing of Ground LoopS sized incorrectly
Ground loop plays an important role in functioning of geothermal system. While an undersized loop will result in an inefficient system leading to a frozen or overheated ground loop, an oversized ground loop will result in unnecessary extra consumption of energy. Never use “rule of thumb” for sizing your ground loop. On the other hand a good HVAC contractor should consider factors like flow rates, soil temperature and conductivity.
