The truth about most HVAC companies is that anytime your units have an issue they want to automatically sell you brand new units instead of figuring out or fixing the problem. Not only is this a sign that they don't have knowledge or experience needed but it shows all they care about is your money. Thornberry Bros not only does great job installing new residential and commercial units but they have the knowledge and experience to maintain, repair and back up the work they do. This is so rare to find a company that can truly provide service even after your new install. They have went above and beyond on all of our residential and commercial HVAC needs. I recommend them to everybody who is tired of being taken advantage of by companies who are out to get your money. Great job!
