On the day of the install, the technicians arrived on time and were extremely courteous, hard working, and knowledgeable. One of them even brought to my attention a very small leak in the water line to my water heater. I had no idea it was there! They answered all of my questions, explained my new system to me, and when they were finished they did such a great job of cleaning up that you would never know they were there!

The technicians at Climate Systems were awesome. In fact, they were phenomenal! I was extremely impressed. They weren’t the cheapest, but they were close to the least expensive. They were professional and handled things more professionally than I expected. They did a great job at explaining the installation process. My father was in air conditioning, so I know a thing or two. I highly recommend them if you ever need an air conditioner installed!

The same gentleman has come from Climate Systems for the past several years. He arrived between the hours we had pre-arranged. He is familiar with our house and HVAC system because his company installed it. He worked in the basement and then adjusted the thermostat in the dining room to test the various functions. He left the work areas clean and was, as always, courteous and professional. They come highly recommended in my book!
