EXCELLENT Based on 66 reviews Posted on Keaton SmithTrustindex verifies that the original source of the review is Google. Luke came on thanksgiving morning to fix our unit and even explained everything that was going on in it so I would know what had happened in case it happened again. It doesn’t get any better than this when it comes to customer service and friendliness. I now have a much better understanding of my AC unit and will continue to only use Luke going forward!Posted on Alexander MillerTrustindex verifies that the original source of the review is Google. Hands down best guy in the business. Super quick and very honest. Extremely rare to see either of those qualities post 2020. Thanks Luke!Posted on Tina DavidsonTrustindex verifies that the original source of the review is Google. My hero !! My system broke on Saturday morning and he was on top of it to fix.

Luke is the best AC person I have ever done business with, takes the time to explain what is going on and does not try to sell you things You don’t need. Alpha comfort and Design is the only AC company we will ever use. Thanks Luke TimPosted on Yvonne MvquireTrustindex verifies that the original source of the review is Google. Luke is the absolute best. He literally saved me $800+ dollars. I chose an expensive mini split to be installed and he took the time to researched a mini split (same brand) that worked best for what I needed. It was the same thing, just less expensive. He is very honest, friendly, polite, great sense of humor and definitely knows his stuff. He entertained my and my fathers questions and explained the process to me. He cleaned up after the job and went above and beyond what a is expected of an AC company. If anyone needs to contact me as a reference, please ask Luke to share my info. He is hands down the best. Not to mention, he did not overcharge. The price he quoted was what he charged. And, what I paid was extremely reasonable. He is a good person and he worked non stop until the job was done.Posted on Lindsey SwindleTrustindex verifies that the original source of the review is Google. Luke is responsive, reliable and has provided same day service. His work is the best I have worked with and is of good value. He is knowledgeable and trustworthy. He has helped me to learn how to take care of my AC unit. I highly recommend Alpha Comfort Design, you will be grateful you called.Posted on Cristen CarrTrustindex verifies that the original source of the review is Google. A company, let’s call them Hank Gray, told me yesterday I need a new unit because my unit is operating with 50% R22 refrigerant, which is no longer available anywhere in the world. Also said they could not resolve the issue of my unit tripping. Got a second opinion from Alpha today. None of that was true!!! Getting a refund on the down payment I paid to Hank Grey, for a new unit I don’t need. 100% recommend Alpha and will use them when I do need a new unit!Posted on Aimee HuberTrustindex verifies that the original source of the review is Google. Our family has used Alpha Comfort Design for a few years now after being referred to them by a co-worker, following some negative experiences with other companies. We have never had a better experience with a company. Luke is honest, knowledgeable, and detailed. He explains everything well, treats your home like his own, and his pricing is very reasonable. Honestly, my husband and I couldn't say enough great things about Luke and our numerous experiences with Alpha Comfort Design. We know other families that also use them and have had outstanding experiences as well. This is an honest, dependable company, and we'd recommend them 100%!Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.
