The HVAC (heating, ventilation, and air conditioning) systems are one of those complex pieces of machinery that most people rely on yet have little knowledge of how they function. The heating portion of the HVAC makes use of either electrical resistance or the combustion of natural gas to generate heat. The heat is then transferred to the air exchanger and into the air ducts. Many homeowners prefer one type of energy usage over the other, but there is very little difference in efficiency with a modern HVAC Replacement in Folsom CA. For some folks, the safety of a gas-free home easily offsets any variance in operating expense.
The AC portion of the HVAC is a more complex component because the AC must compress a chemical refrigerant. Compression forces a state change in the chemical that allows it to collect heat as it passes through the evaporator coil. The heat is carried outdoors where it is released into the air and the refrigerant is ready to be compressed again. This constant pressure change, and the heat that results, can put a lot of strain on the condenser and is the main reason that the refrigerant should be checked annually. AC refrigerant carries the lubricant that protects the condenser and reduces the chance of wear. A damaged condensing unit can be an expensive repair. In some cases, such as the replacement of an older system, it may be more cost effective to have a complete HVAC Replacement in Folsom CA.
Replacing an aging HVAC can be a huge task. First comes the removal of the old system and the testing of any ducts connecting to it. Assuming that the replacement will fit in the same space, it may be possible to reuse the existing air ducts. However, old air ducts can be a huge source of air loss and may need to be repaired or replaced. It pays to discuss all possibilities with the contractor before the job begins so no unexpected expenses arise. It is also important to get the right size system for the building. Have the contractor calculate the exact requirements for the square footage of the building. Visit the website for more information about HVAC installation and replacement.
