Old coil with HVAC Refrigerant Leaks
Old Leaking Condenser Coils (also referred to as freon leaks) can cause serious issues with HVAC heat pump equipment. HVAC refrigeration circuits are designed and built to hold the refrigerant. It is a sealed hermetic system. The HVAC refrigeration circuit should never need refrigerant. An HVAC refrigeration system does not burn refrigerant. The refrigerant is used over and over again to move heat from one place to another. Aside from a leak, once the refrigeration system is properly charged, the system should never need refrigerant for the life of the equipment. (more…)

Condenser Coil Repair - A crane is used here to lift a new condenser coil to a rooftop. The old condenser coil was leaking and could no longer be repaired. The process involved recovering all the refrigerant from the Trane rooftop unit.
The rooftop unit was then partially disassembled and the old coil cut out from the system taking great care and planning to ensure the new coil could be retrofitted to the old refrigeration piping system.
Good planning and skilled HVAC techs make the jobs go smoothly and make the replacement seem easy especially to the customer. (more…)

Learning the Basics of HVAC - To understand air conditioning and heat pump applications you will need to study refrigeration. Both air conditioners and heat pumps use refrigeration to move heat. Air conditioners move heat outside in the summertime using the process of refrigeration. Furthermore, heat pumps move heat in both directions (to the inside in the winter and to the outside in the summer) using the principles of refrigeration. (more…)

Basic Heat Pump Maintenance - A good heat pump maintenance plan will include a thorough check of the refrigeration system, the electrical system, the heat pump controls, and the air filter system of the heat pump. Heat pump maintenance is as important as maintenance on your vehicle. If we fail to take good care of our vehicle then it is more prone to breakdowns whereas if we keep it in good condition with proper maintenance it is more reliable and repairs usually cost less when repairs are needed.
Of course, if you take good care of the heat pump with regular maintenance major repairs will likely never occur and it is possible you will repair free with a good maintenance plan in place for your heat pump. Basic maintenance adds life to the equipment, keeps the equipment running longer adding to the lifespan, and during the overall life will keep the heat pump more efficient.
