We had been having 3 wks. of rennovations/remodeling to our house when Randy, Drake State Air service came exactly at the 8 am scheduled time for our furnace check-up. He overheard me talking about how the wood floor contactors had not fixed the furnace sliding door. Randy noticed the screws were stripped but while he was sitting on the floor servicing our furnace, he was able to remove the screws. He made suggestions about what to use and how to fix it properly. He did a great job, very professional, but friendly and thoughtful! So glad Randy was our serviceman! We love Drake State Air!
