I am in the processing of trying to but a furnance and AC. I am trying to do my homework but it is confusing. I am trying to find out the correct information on Lennox, Air Ease and Trane. I ruled out Carrier because it was a nightmare experience dealing with the company. My compressor on my AC went out in less than 3 years and they would not back their product. I am giving you a call at your toll free number and would appreciate any information you would be able to give me. Thank you for your time. Confused & perplexed.
