Repeat customer. Got a new HVAC/AC unit two years ago, and when we needed to change our first floor unit, I only called McNallys. Russ has worked with us both times. He is great and I would recommend!

Angel was polite, professional and efficient. Even though I called at the last minute, Angel came to the rescue. He cleaned my furnace. And gradually, it went from 60 degrees to 70 degrees. Angel is an asset to your company. He was fantastic. Thanks to all of you for helping me with my "heating" issue. You guys are the best. I will be using you in the future.

McNally's is the best! They installed my AC unit last summer and today they came to do a maintenance check on my furnace. The technician Brenden was great! He was very thorough and checked that everything was working as it should be. I renewed my maintenance agreement without hesitation because I will not go anywhere else now that I've seen the care that McNally's takes of their customers.

We needed a new furnace due to a crack in our furnaces heat exchanger. We went Costco and learned about McNally's. It was a no-brainer.. No one can beat McNally's and they offer solid customer Service from Sales to Installation to Service.

Furnace went out Friday after Thanksgiving. Brendon fixed us up that night after a looong day.

Recently during our annual tune-up, Esteban quickly noticed a crack that was emitting CO. Our furnace is only 6 years old so this unexpected issue caught us off guard. The entire McNallys team was extremely patient and explanatory as they helped us work through the issue. We ultimately decided to replace and upgrade our current system with a better one, and within four days, our new system was properly installed and working. The installation team was neat and efficient, I was so pleased. Thank you to Russ for helping us with the financial paperwork and rebates, he came to our home twice to make sure everything was in order, despite it being a holiday week. We look forward to continued work with McNallys and highly recommend them to anyone in the area.
