Called Keith to get take a look at the furnace. Unfortunately it needed replaced and they gave us some pricing. Decided to go with it and they put in a high efficiency one for us. I did have to call them back a couple times because it stopped working intermittently. Took a couple times but they figured out the original installers undersized the vent. They fixed it and has worked great since. They were always on time and super respectful of the us, our pups, and the house. I would recommend them and plan on calling when We install our central air.
EDIT: We did end up calling Keith for the AC. Keith came out and looked everything over and gave me suggestions on how to make everything work. The other 2 companies I had come in told me they would add the AC and hoped it worked. I decided to go with Keith and his guys were great once again. It has been working wonderfully and this summer has been much more enjoyable. They earned the 5 star review.
