It is estimated that over half of all air conditioning systems operating in the U.S. were not installed properly.
An improperly installed system will not work efficiently and will result in expensive repair and utility bills. Hiring the cheapest contractor is never a good idea, and when it comes to the specialized and complicated industry of HVAC – you definitely need to hire a professional. The company that comes up with the lowest bid will have to cut their costs somewhere.
Examples of improperly installed air conditioning systems can include: undersized and un-insulated refrigerant lines, ducts not sealed or insulated, over sized or undersized air conditioning equipment, mismatched indoor and outdoor sections, improperly charged refrigerant, wiring that has not been upgraded.
Ever hear the saying "Jack of all trades – master of none".
A company that offers Air Conditioning, Plumbing, electrical and other services may not be able to offer the same high level of quality and service as a company that specializes in only Air Conditioning. Your local handyman definitely does not have the knowledge or the experience to properly maintain or repair your Air Conditioning.
Much in the same way that the backyard auto mechanic has become obsolete, the increasing sophistication of today's air conditioning systems requires technicians to constantly fine tune their skills.
