We were treated very professional

These guys started the morning on time. When they got to the site, they made sure that all of the material was there. They did’t spend alot of time running back and forth.They are very hard worker and they make sure that they PICK up behind themselves! I’m getting alittle ahead of myself, when Billy came he made sure that everything was explained to us. He took time to make sure that the unit we wanted was the right one for our home. We were treated very professional. I would DEFINITELY use and RECOMMEND this company to everyone.

They're very helpful and knowledgeable.

I called them at 9 o’clock and they were actually willing to come out at 9 o’clock on a Saturday night but I told them just to come on the next morning. They came here Sunday. They’re always there when I needed them. They’re fairly priced. It’s a family business. He didn’t charge me any extra for that. They’re always there available for you. They’re very helpful and knowledgeable. They offer their service 24/7.

Best investment I have ever made

Shane & Billy did the install. They were very professional, and courteous. After installation they spent time with me ensuring that I understood how to operate my new system. Billy checked back with me several times after the installation to see if everything was working properly, and if I had any questions. If I have a question when I call them someone calls me back the same day. I can’t say enough about their service and their product. I love my new system. Best investment I have ever made. I would recommend this company to anyone I know.

delightful experience with this outstanding company

I have never written a review before, but I had to share my delightful experience with this outstanding company. First of all, the way I found out about Moreau’s is that my step daughter called me., raving about them. Shortly thereafter, my A/C went out on a weekend. I had a service contract with another company, so I felt obliged to call them first, and so I did. I waited and waited and waited……Read more

Very professional, very polite, and knowledgeable

They always seem to really care of what they are doing. They’re very professional, very polite, and knowledgeable of what they do.

had a fantasy experience with them.

Robert and Ross came by today to do the heating service on our two units. They performed a very thorough service and worked fast and clean. Very friendly and even offered to put our Christmas bins back in the attic while they were up there. I highly recommend Moreau and we’ve always had a fantasy experience with them.
