"They installed a minisplit cooling system, with 3 exchanges June 2021. Since then it is not operating the way it should. In my bedroom with the door closed at night on cool at 70 degrees the humidity goes up to 80%. I wake up uncomfortable, change it from cool to dry mode. The humidity will go down into the 50% range but the temperature drops down to 62 or less! So in cool or dry mode I can't get a good nights sleep! They come and look at it and tell me everything is fine. I'm going to buy a window air conditioner tomorrow which seems insane because i spent $10,000 on this minisplit AC system!"

"We had an emergency after a power surge that fried our furnace. Varsity was at our home first thing in the morning. Ralph went through a thorough diagnostic process with us, went over all of our options with prices, and we ultimately replaced our entire unit. The work was done efficiently within hours. No mess to clean up afterwards, and the techs at Varsity returned our home to the safe, warm environment we needed in preparation for a large winter storm. The techs took proper precautions when entering our home, even going so far as to wearing shoe coverings to protect our floors. The service manager communicated the entire process with us before it was happening, keeping us informed every step of the way. The employees at Varsity treated our family like their family. They made our urgency their priority. Every employee we spoke with was kind, respectful, and thoroughly educated on the situation, even the customer service representatives. This company will continue to serve us through the years. They’ve earned our trust from day one."
