Justin was very respectful, friendly, and very professional. He answered all my questions about my HVAC system in layman's terms, which helped me understand some of the issues I was having with my unit. He made a recommendation of a surge protector and the importance of having one. I agreed that it was a good idea so he installed.I feel a sense of relief since N.Raleigh gets so many lightning storms and I want my unit to be safe and working properly.
