An interview with Trane on A major HVAC manufacturer surveyed its customers in 2002 and asked them about their priorities when purchasing heating and cooling equipment. The customers ranked their preferences in the following order: If you've visited the websites of any central air conditioner manufacturers, you've no doubt seen claims about quality, yet no one does systemmatic quality comparisons of air conditioners.

Here are some of the components that affect the quality of

The most expensive part of a central air conditioner is the compressor. The compressor increases the pressure on the Freon (or Puron), and releases heat. (The compressor is located outside in a typicalSeveral manufacturers use scroll compressors instead of conventional compressors in their high end air conditioners. Scroll compressors involve less friction than a conventional compressor and this increases their reliability and typically makes for a quieter unit. Another mechanism to protect the compressor is a "short-cycle" protector. the compressor is cycled on and off quickly (within a period of a few minutes) -- perhaps because of a loss or power, or an over-active thermostat. Because short-cycling can shorten the life of a compressor, a short-cycle protector enforces a five or six minute wait after power interruptions. The casing itself helps to protect the components stored outdoors. Some manufacturers offer special panels, paints and even weather-resistant screws to provide better protection.

While not directly tied to durability, manufacturers are beginning to offer self-diagnostic tools which can assist HVAC contractors during service calls. Some of these tools can also store error codes for several days, or even contact a service contractor directly!Best Central Air Installation Companies in Baltimore, MD 2016 This company provides professional HVAC services for commercial and residential properties.
