I am going to have to replace my 2 heating and air systems on my home soon. Are there any recommendations on brand names etc. that have best reliability? My neighbors have used Trane with one of them having to have the compressor replaced after only 4 years.
Also, are the any comments on the efficiency of the units? Is it worth the extra money to go for the higher efficiency units or the extra filtration systems etc.? I have seen some comments on sites that say they are only there to run up costs and do little for the air quality.
