I have intentionally waited a few months before reviewing my new furnace. It's GREAT. I purchased a top of the line variable heat furnace and it's already paying for itself. When I compare my natural gas bill for the last few months compared to last year this time my new furnace is definitely more efficient. The new electronic thermostat is really easy to use even for a non techie like me. Kelly (the owner) walked me through the different furnace options which was really informative but not hard sell. The crew that came out for the install were all super friendly and efficient. I highly recommend Able Heating & Cooling. They also installed a new air conditioner which I haven't used yet so stay tuned for that review :)
