“We couldn’t ask for any better workers than the ones who installed our unit. They were really efficient, courteous, cleaned up the site really well, and both answered my stupid questions without hesitation. The vibration noise we experienced is now gone, thanks to the opening made. We plan to use your services in the future. Thank you Michael MacNider for your initial visit – it made us well informed. You are a great salesman.”
