I recently had a mini split installed by McWilliams and couldn’t be any happier! After searching for someone to install with no return calls from other companies they were quick to respond and get out to my house for install. They did an amazing job on my unit and my house finally has cool air/heat definitely more efficient then box ac and space heaters. Everyone was extremely courteous and made sure the job was done right to my liking. I couldn’t have had any better of an experience!.”
