This is an outstanding company when it comes to customer service. The owner, Mr. Arens, and every employee on the staff is friendly and intelligent. Dave is our favorite technician. He's very thorough for the furnace and air conditioner inspections. They charge about $70 per visit and I get a new filter each year. It might sound expensive, but preventative maintenance saves money in the long run. A few years ago, Arens Heating & Cooling installed our energy-efficient furnace, which has been great during this time of high utility costs. Also, I've talked to the owner about the efficiency of space heaters and I was really impressed by his knowledge. I highly recommend this company.
