Used this company to service our heating system under a maintenance proram. The service tech arrived on time and was very polite. He replaced a processor board (at about $800) and had the system working well. He told me that, if we decided to replace the entire system (ours is 13 years old) the cost of the repair would be deducted from the cost of the replacement. This offer was good for 30 days according to the tech. Three and half weeks later we decided to bite the big bullet and replace the system. Called the company and was told that the offer was only good for two weeks. Later in the conversation was told it was only one week. Needless to say, somebody somewhere told a lie. I will not renew the maintenance contract nor allow this company back in our house. Once burned, twice cautious.
