I called Cozy World when my A/C broke down early in the Fall. It was a 15 year old unit and the service person advised that the repair would be costly and it was time for a replacement. Cozy World's pricing beat others by quite a bit and they were able to source and install a new unit just two days later. During that install they discovered that my old furnace had a crack in the heat exchanger. The installer showed me the issue and explained the safety issues. Cozy World was able to provide a fair price for a new furnace and install it within a couple days. The installers were knowledgeable, careful while working in my home and made sure everything was in order before leaving. Cozy World also registered the warranties and forwarded all the paperwork for my records. It was super efficient and would highly recommend.
