2 months agoWe called Swiss Air to repair a leak in our gas lines. Our technician, John, was great to work with. He was friendly and personable, explained what needed to be done, and fixed the problem quickly. He also arrived within an hour or two of us calling. Overall, the experience was great, the price was reasonable, and the work was done well. We'll definitely call Swiss Air again if we need help in the future. -

2 months agoWe had Swiss Air come out to put humidifiers on our furnaces. They were able to quickly get us on their schedule and the technician was friendly. About two weeks later, the humidity in the house still felt low and the humidity reading on the humidifiers never seemed to reach where it was set to. When we called, they promptly came back out. They mentioned that the fan wasn't hooked up quite right and fixed it. However, it still seemed like the house was dry and the readings never matched what it was set to. A few weeks later, one of the furnaces stopped working completely and was covered in several inches of ice. We called out a different company this time and they quickly figured out that the humidifiers were not installed correctly and were missing a relay, which was causing the a/c to be running at the same time as the heater almost constantly. At this point we let the other company fix it instead of giving Swiss Air a third chance to install it correctly, costing us about $500. Now, the reading finally matches what it's set to and the house feels less dry. -
