Here's what our satisfied customers are saying...
I am a new home owner and I had William G Day company come out and do routine work. Scheduling was easy they work with my busy schedule and the technician was very informative when going over everything I should do to help maintain my system. Completely recommend!
I'm a fan of the little guys, not the big deep pocket companies. Been using these guys for a few years now. Thanks for doing a good job on my heater & AC maintenance every year.
Our old heater went out and had W G Day company to replace it. They did a great job replacing the unit at a very reasonable price. The crew showed up on time and cleaned up nicely after the work. Toby was responsive to all my questions and followed up after the work. Highly recommended.
Met with one of the managers about my water heater, nice guy, answered all my questions. Sent me some price options and scheduled a plumber out the next week. Very happy with my new tankless water heater. Thanks again.
Chris was the service pro that took care of the work I had to get done. He was here at 8:00am on the dot as promised. He got right to the jobs I had asked to be done.Installed two new faucets in our bathroom, new shower head and fixed a nonworking body shower head. He was vary courteous, neat, and very knowledgeable about his job.
Excellent and prompt service from serviceman Dave. Pleasant and informative. I will refer your company to friends and family.

We have used William G Day Company for several years now. The staff and service representatives are always pleasant to deal with. They are knowledgeable, prices are reasonable and they fix only what is needed.
I am happy with their company. I used them at my home and my rental property.
William G Day provide a new Air Conditioner system with the Carrier Infinity Unit. Toby was very responsive and modified his proposal several times to meet our requirements. We got a very good price and excellent value. Toby, Kevin, and Marco were courteous and great to work with. The installation was on time and on plan. I recommend William G Day and will go to them for all my future business.
I want to let you know what a great crew you had doing our AC installation. They were not only very competent, but exceedingly courteous, careful, considerate and took the time to communicate with us throughout the job. Please give them our thanks (again) and pass on to others how fortunate we were and think you are to have them on the job.
