Gavin was very personable from his phone call prio to arriving on time, to his instructions on how to operate our unit when he left! Talk about professional! He even vacuumed the area involved when he left. Woke up to a warm house this morning. No cold spots! Love this quiet unit. No more loud cadet heaters blaring. Gavin had all the paperwork ready and filled out. Even had the tax papers and envelope ready, addressed and stamped! Arrow should be proud to have Gavin on their team!
