    • Cyndi Davis· September 2026

      Ben and his team were exceptional! We were in dire straits and had a wedding happening on a Saturday afternoon. It was 100° outside and the air conditioner went out. We had 100 people showing up in just a couple hours. Not only did they come in after hours and return multiple times with the correct parts needed, but they went above and beyond to make sure that our guests had air-conditioning! I could not recommend them more! Ben and Dave you guys were unbelievably amazing! These guys will be the first guys I ever call in the future!

      John W performed summer maintenance on my HVAC. He gave ample notice of his arrival time, was friendly, and very thorough.

      Their technician was very knowledgeable and did not try to over sell me on anything during my seasonal maintenance appointment. He let me know what could wait and what to look for to know when something is failing so I could contact them to schedule a repair.

      Came when expected, very efficient in diagnosing the problem and super friendly. I thought I was at least gonna spend some big money but the tech located some loose wires and fixed it for free. Couldn't be happier with the service and would highly recommend to anyone with a downed HVAC system.

      Tyler was great very professional and very friendly! He lets us know what's going on with our unit and is always more than willing to answer questions. We've had a great experience with this company and it's nice to know that when something goes wrong they are just a call and a quick visit away.

      Excellent job in every way. The original tech diagnosis advised us not to try and repair our ac unit .we chose to replace it and he did a great job of scheduling us right away.the salesman was terrific and the financing took maybe 5 minutes..the installers were on time and hard workers with great personalities .we love our new ac/furnace and the price is very competitive.highly recommend!!

      Cody with Swiss Air was great. He explained everything was doing for my summer maintenance and took his time with every task to make sure it was completed properly. Had another visit due to my capacitor going out. Tim and John were great and even called to see if it was under warranty for me still. I wasn't, there were none in stock, but they got be a close replacement in and AC back while the other part comes in.
