On Wednesday Nate came to look at my ac system not working. It was a 30 year old system and would cost way more than I wanted to spend on it to repair. On Friday Josh came and quoted me a new ac and furnace. The prices and rebates were acceptable to me so we scheduled for Monday to have them come in and measure for the air handler. Monday at 9:30 am they called and could get it installed the next day! Today Neal and Trevin came to install the system and by about 3:30 it was up and running! The whole process from the first call to installation was seamless. Every person I talked to on the phone or in person were very nice and very helpful answering any questions. I look forward to doing business with Kalins for many years to come!
