McNally's was professional, on-time, and very respectful of my home. They finished a dual zone AC/Furnace installation in half a day. Craig quoted the job and was extremely competitive on pricing. I highly recommend McNally's for your home HVAC needs!!!

Cory was fast, efficient and a great communicator. He called on his way and was at my house when he said he was would be. He explained everything that was wrong, what part was needed and why. Always nice to have someone talk to you instead of at you when you aren’t totally sure what they are talking about. Appreciated his patience.

Russ really helped us find the best product for what we were looking for and worked with us on our budget needs. He was friendly and gave us all of the information we asked for. Even after installation, he checked in on everything and remained available if we had any questions.
Tyler and his crew were also quick with installation and did an excellent job. They were respectful and got the job done during the expected time frame.
Great service from everybody at McNally's!

Not sure if Angel has even left my driveway yet but without haste this review needed to be posted. He was awesome. Honest, knowledgeable and helped talk through some potential plans as I deal with an old AC unit. He got it going immediately and again, helped with a plan of action moving forward. Highly recommend.
Would like to add a huge thank you to Fred who came out a few weeks later as my unit continued to fall apart - he helped shore it up until we can have McNallys replace the unit. Once again, super accommodating and knowledgeable.
