Duct Cleaning

Report

The first step in our process is to lay sheets down and if we are not on protective sheets we will be wearing boot covers to protect your floors. After the sheets are laid we will run an 8 diameter, non-marking hose from our Duct Cleaning Unit to the ductwork in your furnace room. We will attach the non-mark hose to both the supply and return air ductwork.

Made a deal with the owner of this business and apparently all he cares about is his wallet and himself. Very unprofessional and hid behind his elderly secretary to pass blame for his choices. if your looking for someone that is non trustworthy and only cares about himself and non local Billings people look no further than this man

My experiences with ACT have always been outstanding. They are the utmost in professional service and I have recommended them to friends and family. Our furnace quit last night. I called at 8am and and Penny sounded very concerned that our heat was out. She said she would have someone out as soon as possible. Trevor was here at 9am. He quickly diagnosed the issue and had a blower motor here and installed within an hour and a half! In the middle of the worst cold snap in years, they must be overflowing with service calls and yet they made me feel as if I were their only customer.

Act heating and cooling was such an amazing company to work with. Drew was so helpful and kind with the elderly couple we had him work with. The way he showed not only care for getting their heat back on but the extra mile he went for them shows not only the outstanding character of the company but Drew himself. We can't thank Act Heating and Cooling enough for their help and the compassion they and drew showed towards a couple in need. Will defiantly be using and recommending this company to all people in Billings.
