We've been using Classic Aire Care for a couple of years. We signed up for their maintenance program where they show up every quarter to look over our equipment, change filters, clean blowers and compressors, and make sure the system is working up to standards. They are quick to point out potential issues and give an estimate to how much life might be left in a questionalble component. They've never been wrong and our heating and AC have always performed flawlessly, winter and summer! Can't say enought good things about these find folks.
