Sister fails to verify integrity of HVAC contractor before investing in A/C installation

Unfortunately, they also messed up the actual installation of the cooling equipment

A little over a year ago, my older sister replaced her home’s air conditioner. Marcie couldn’t wait to brag to me about the exceptionally high SEER rating. She was so impressed with the manufacturer of the cooling system she chose. She told me how her new air conditioner was a very expensive and top-of-the-line model that included all these awesome features. Marcie was so sure her monthly electric bills would be cut in half and her house would be far more comfortable, cleaner and healthier than mine. When I asked about the HVAC contractor who was completing the installation process, she had very little information. Marcie had noticed an ad in the newspaper for a free estimate and called them up. The guy talked her into all of these expensive upgrades with promises for low utility bills and amazing comfort. I was shocked that she hadn’t bothered to read customer reviews or verify their rating with the Better Business Bureau. My sister didn’t even know whether or not the company was a factory authorized dealer or guaranteed their work. She wasn’t sure if the technicians were NATE-certified or fully licensed and insured. I wasn’t surprised that when the air conditioner was installed, Marcie wasn’t happy with the guys who showed up. She said that they delayed the installation project multiple times, showed up late for the appointment and tracked dirt through her house. They left debris behind for her to clean up and never explained the features or operation of the air conditioner. They didn’t handle the registration for the manufacturer’s warranty. Unfortunately, they also messed up the actual installation of the cooling equipment. Whenever the air conditioner cycled on, it rattled and wasn’t putting out much air. She ended up calling a different company to come in and resolve these problems.
