Convertible Heating and Air Conditioning

HORRIBLE BUSINESS!!!! Stay Away!!!!! We are In the process of suing in Small Claims for cost of damages.
We bought a new house and they had installed the new AC. Every couple of days our AC was freezing up and would stop working. We had 2 different HVAC technicians come and ended up having to tear apart dry wall to discover the problem. Electrical work discovered to be done illegally!!!!!!!!!!!!!! AC is 50 amp, control panel is 40amp - 10 gage wire used. After contacting them many times, they refused to change the control panel and wire. They installed a 4 tonne AC with a 3/4 copper pipe when MUST (by manufacturer manual) used 7/8 copper pipe based off the AC manual. MAJOR cost savings corners were cut that they are taking no responsibility for. This fire hazard would have never been discovered until it was too late if it wasn't for our HVAC technicians. Sam was VERY rude to deal with and refused to send out a technician or to acknowledge any wrong doing. Unfortunately, as this will cost a hefty amount to repair and replace and we have decided to sue.
Do yourself, and your wallet a favour and STAY AWAY!
