Roughly 5 years ago we had a licensed, reputable a/c company install a completely new Coleman ac system in our house. Unfortunately, every year, the circuit board in the air handler would break down and require replacement. It has been replaced at least 4 times now. Our technician has taken several other steps, as directed by Coleman, to try and troubleshoot and resolve the issue over these years, none of which helped. It really comes down to this air handler being a lemon. Our technician has tried to get Coleman to be helpful and cooperate and understand that he has done everything possible to fix, yet, he has stated that, "Coleman is unwilling to to pay any of the labor or anything for that matter". This is extremely disappointing from a customer service standpoint. Every year Coleman put off replacing the unit, and now they will do nothing. Very disappointed in this company, and will cease to buy any product from them from camping to everything else. This company does not back their product, And they prove that they are not willing to help even when it is obviously a product defect.
