Alfred came in a timely manner and was very polite. He didn't mark up any of the walls or the doors with the equipment. The company had followed up on a repair that was done 2 days prior and the technicians had done an amazing job of a hand off so Alfred knew what he had to check without me having to explain. He did a thorough job of explaining everything that was done and showing me the damaged items that needed to be repaired. He helped me find good spots for my carbon monoxide detectors and told me where to store my furnace filters. This was my first time having my furnace serviced for a tune up and I would do this again. Thank you.
