“I was very happy with this company until they provided me with an estimate for a hot water heater install. To start with, the estimate estimated the wrong product. I asked for a 50 gallon tank and they estimated a 40 gallon tank. To make matters worse, their estimate for a new water heater, without my 20% discount for having a maintenance contract, was over $600 more than the 4 other estimates I got from local HVAC companies. It is clear that Cardwell simply jacks up the cost of the unit before they provide the customer with the 20% labor discount. I spoke with the manager, Terry, and she advised that different companies charge different prices for the same thing. While I generally agree with that, I advised her that is impossible that their estimate for the identical unit, before a labor discount, was $600 more than their local competition. I think it is pretty clear that their promise of a 20% discount off of their labor rates is false and misleading since they increase the price to account for the discount. This conduct is unlawful and it will be dealt with! Extremely hard pass! I will bet they will not post this honest review on their site so I will post this elsewhere.”
“Sean came out when our heater wasn't working and spent a great deal of time trying to get it up and running. Once we realized we needed a new heater, John was able to come out quickly and provide options without any pressure. Installation was done in a very timely manner and installers were friendly and clean and did a great job.”
