This was a post I did 3 years ago. I accidentally posted it to a Sam's A/c. I didn't realize that I wanted SAM HEATING AND A/C. SO HERE GOES. What a group. They called me to let me know they would Show up 30 minutes early and was it ok with me? Absolutely. Sam came personally and went through my a/c system. He determined he needed to come back and do some further work as he needed some parts. Gave me the bid and it seemed reasonable. 2 days later he was 20 minutes early. I thought with all the extra work that this project entailed, he would charge me some additional money

I recently purchased a new home (older home, 1960's) and it needed a complete makeover from top to bottom. With such a big purchase/home improvement I sought after three bids before beginning the project. Sam came in with the best price and the best name brand equipment. I had a brand new AC compressor installed on the side of the house, brand new furnace installed in a dedicated closet, brand new vents and duct work routed throughout the house. Like I said it was a big job. My fianc and I could not be any more happier with his service. Sam and his crew were prompt polite quick and cleaned

Sam just installed a new AC system for me at my rental yesterday. I had 3 quotes from different companies and Sam gave me the best product, service and price. He and his crew did a fantastic job. I highly recommend this company. Great Service, honest and professional. I will continue to use their services in my home and my rentals!

We recently need a mini split for our upstairs master bedroom . Sam and his team were so professional and reliable. I liked how they wore booties and placed barriers to walk on to protect our floors . We had our mini split installed well and in a matter of hours . I highly recommend their services.
