Our furnace broke down last week and our neighbors recommended R.K Heating and Air. They came out the same day and come to find out our furnace was pretty old and not repairable, so they recommended a new furnace. They gave us a good quote and warranty. They came back and installed the furnace the very next day. All work was done as expected. New furnace is quieter and more efficient than the old one. Thanks for the quick and friendly service.
