Blake and Luke were fantastic!

1/4/2017

I've been a Guthrie & Sons customer for several years now and highly recommend them. We had to get a new AC/furnace and they made the entire process as painless as possible. Who knows how old the previous units were but we needed something in ASAP. Since the sales appointment it was just a few days for the install unit to come in. Blake and Luke were fantastic and always super aware of professionalism and cleanliness - we have dogs so I needed our home to be clean otherwise my pups would get sick. On day two of the install another crew came in to help so there were four Guthrie & Sons vans parked outside - it was awesome! They worked so hard and did a fantastic job. A BIG thanks to everyone from Jessie in the office (she is fantastic) to Matt, Luke, Blake, Nick...They are all great and you'll be happy to work with them.

Great service. Great product. Knowledgeable staff. The technicians came out went over all work and explained everything. They were very clean and left no traces. Everything that was installed was clean and had great fit/finish. The price was the best in town. If you are looking for any heating/air conditioning these guys should be first on your list.

I'd definitely hire them again or recommend to a friend.

Needed to replace an old air conditioner for my 1940s home. Guthrie & Sons provided a prompt quote and let me know what to expect during the whole process. They were able to work with my schedule, showed up on time and the job took about the time they estimated - even with an unplanned work around due to my original set up! Very conscientious about keeping dirt and dust outside. Cleaned up the whole work site. Follow up testing was scheduled and passed. I'd definitely hire them again or recommend to a friend.
