Todd Lityma serviced our heater that was acting up. We contacted Todd after certain rooms in our house were getting too hot or too cold compared to the rest of the house. Todd quickly came up with a solution and saved us a lot of money! We really appreciate him and United Heating and Cooling. My parents have been using United for a while and they were the ones who originally recommended United. We are very pleased with their service! Thank you again United and Todd!
