This review is based on my experience with the sales adviser. I had comfort issues in an older home we just moved into. I called the major reputable companies in my local area with good reviews-Howard Air, Day and Night, Hobaica(worst). I was frustrated as each of the advisers said they would follow-up, and none would. Probably a busy time of the year-before summer and the scope of work was complicated. Jason Waller from Larson Air was the only adviser who took the time to follow-up and bring his service manager Dean to trouble shoot the problems. They showed up on time and were clean and professional. The scope of the work needed in my home would eventually involve a General Contractor. I would recommend giving Larson Air a chance to earn your business.
