Today my new air filter system was installed by J. A. Bertsch Heating & Cooling, I'm looking forward to the benefits of it assisting me with persistent allergies. Their employee, John, was well experienced and explained in detail the equipment and minor maintenance on my part. While he was here, he checked out my AC. Noticing how loud it ran, he replaced a part at no cost to me, and the problem was instantly fixed. I'm very impressed, and highly recommend this company.
