Our furnace went out completely, so we reached out to 2 companies to get their bids. Even though they were more expensive, we decided to go with Complete Comfort Heating and Cooling. Both companies said the same thing, in terms of the issue, but their salesman explained everything much better, and their warranty was better, as well. They were flexible with scheduling the appointment, and the installers came very quickly. They were very prompt, polite, and even took their shoes off when they entered our home. In about 5-6 hours, they installed a brand new furnace, and took the old one with them. I would use them again in the future.
