I had an ac unit installed by hectco. About 2 weeks after installation I am awoken by high pitch noise. Told since noise intermittent and still had warranty then call back if had any other problems. Called back numerous times and finally tech sent out. Found burnt wire and said problem electrical. Electrician stated Problem with ac unit. Called company again dodged calls. Guess what? My 2 yr labor warranty out! In the last 5 years company has moved several times. How do you serve someone when can't find? To sum up buyer beware! Gave 2 yr warranty but would not return. Failed to register unit for free 10yr parts warranty therefore voided. Called MS State Board of Contractors and found previous case against hectco. Why am I writing this? So you will not have to go through what I did. PS keep up with receipts! AC dealers were not forthcoming on where unit purchased. They say I need my receipt. Thought computers hold everything? Wrong! It is up to you to prove when installed! Again buyer beware unless you have $6000 you just want to give away Hector!!!!! read more
