Our air conditioner unit was 15 years old and showing it's age. Like most homeowners, we dreaded having to replace it. We've used Comfort-Air Engineering for years and we knew they would treat us well. We were right. It started with an inspection of our current unit. They explained everything so carefully. They told us what our current unit was doing well, what is was doing poorly and all the options we had for replacement. When we chose a new unit, we had no doubt we were getting the best option for our home. Installation day arrived. The team was courteous and professional. They worked so quickly. When it came time to work inside the house, they made sure my carpet and furniture was protected from all construction. When the work was complete, they made sure all my questions were answered. I highly recommend Comfort-Air Engineering because of their hard work and their politeness.
