Several family members recommended (along with dealer) the Goodman unit. I was replacing a 20 year old gas pack unit so I was interested. I purchased a 14 SEER 5 ton unit and everything was good, so I thought. Six months after installation the unit quit heating. Dealer comes out, cannot find a leak, recharges and good to go. Six months later (like clockwork) the unit quits cooling. Again a leak cannot be detected (two techs tried without success), unit recharged. Six months later same scenario, no heat. Up until this point the dealer had not charged me a dime. He contacted the distributor who told him the coil would need to be replaced. I screamed of course because I had purchased a new unit and had had nothing but problems. Why should I be the one to pay for a repair that had been ongoing? I called Goodman Consumer Affairs who told me they would try to pay for some of the refrigerant if I submitted the invoice, no guarantees. I then spoke with a supervisor who was a little more helpful by backing the warranty to date of purchase which allowed the dealer to be paid from day 1 by Goodman (which they should). Then the problem escalated. The part was ordered but would not be shipped until a truck was fully loaded. The coldest weather we have experienced in years, my 70 year old wife and I endured with electric heaters. The entire ordeal has lasted for approximately 3-4 weeks. I asked the consumer affairs supervisor if they had never heard of Fed-Ex and next day service. No one seemed to care if we were without heat (except the dealer) from the distributor to the company.The part received was one that must be retrofitted for the unit, not one that "slides right in" but must be adjusted to fit. As I told the Goodman representative , I am also complaining to the state consumer affairs office. My plans were to have another 2 ton Goodman unit installed this winter in our upstairs but I assure you it will not be a Goodman unit.
