Mark was great. When I first called, he gave me some tips on what to watch out for when hiring someone to do the job. After calling around, I felt most comfortable working with Mark. I booked an appointment for the week after. Mark called an hour before the appointment to ensure we are still on track, and he called once he was here. We did a quick walkthrough and he explained to me what he would do and how he works. He pointed out that the AC is in dire need of a clean as well. I didn't feel pressured into purchasing that on top of what was agreed upon. Looking at it after, it really did need a good clean!!! Mark did a fantastic job and once he was done, walked with me through the entire house, giving me tips on how to take care of everything. I would certainly hire him again.
