The Hassler Whole-Home Approach

When assessing the cooling needs of your home, our technicians do more than just help you pick out a top-quality AC unit. We use a whole-home approach when dealing with your home, and are mindful that all of its “systems”–cooling, heating, ventilation, inhabitants, etc.–are deeply intertwined and interrelated. We go above and beyond a simple install, making sure that your air conditioning unit will function optimally for your whole home, and will complement your existing systems to achieve maximum efficiency, home comfort, improved air quality and energy savings. In addition to AC installations, we offer energy audits and other home performance upgrades to make sure you are getting the most from your HVAC equipment. To help reduce unexpected service emergencies, we offer our annual service agreement to keep your air conditioning system running at peak performance year-round.

Mike, apparently Rene and your team did such a good job the rebate is even a bit higher than expected. Thanks for the good work. Your commitment to qualifying and getting the rebate was a key factor of why my wife and I chose your company for the installation over other companies we received quotes from.
