First of all, let me start by saying that I don’t normally take time to write reviews, however, a review of this company is definitely needed. I run a property management company and have had the pleasure of dealing with Four Suns twice now. Some of our owners use home warranty companies (which can be difficult to get quality vendors out in a timely manner) and this is how we were introduced to Four Suns. They are not only VERY responsive (were out the same day for a home warranty call) but took care of the problem right away and were VERY professional, honest and courteous to our clients. We will be using them going forward for ALL of our HVAC calls! A lot of HVAC companies come and go but I know this company will be around for a long time due to their customer philosophy. Thank you Four Suns!
