I needed to replace my old furnace due to cracked heat exchanger and in doing so decided to add AC, Mike and Tom arrived at the house about 9:45AM and told me that he believed that they could rap up the entire job by 6:00 or 6:30PM if all went well. They got right to work and worked steadily throughout the day and sure enough come 6:00PM or so we were in the testing explanation and wrap up phase. The new unit is performing so well that we can't believe it as for Mike and Tom it felt like I had known for a good while, very trust worthy and dependable. If you have need of HVAC work I highly recommend you contact Drake Heating and Air.
