Olaf saved us!!! On day three of no air conditioning – in Clarksville – we were desparate to find someone who would come, especially since it was the weekend. We googled numerous companies – only to leave messages. We passed a CerProTech van on the freeway and immediately called the number on the side and within an hour we had Olaf and his tech Mike at our house. They were so professional and repaired the unit quickly. I can’t say enough about this company – everyone we dealt with was wonderful. Thank you, thank you!
