Grant and his sons did a whole house installation on a renovation. They did a great job of fitting the equipment in the attic, utilizing a small area for a pipe chase, neatly laying out flex, worked with me in the timing of things between trades, made sure I had heat in the house while working and were great with communication on when they would be there (something many trades area lacking). I highly recommend Banister Heating and Air and will definitely use them again!

Banister Heating and air did all the HVAC work in our new construction. Our house required an ERV system and they were able to help us select the best system and install it in addition to our main unit. We have been satisfied with all of their work. They are respectful, dependable, and professional. We highly recommend them.
