Miller's Heating & Air is a fantastic company. I recently converted to a gas furnace which Miller's installed along with a new air conditioner, an air purifier, and a replacement water heater. I was very pleased with their work. Brian Trenda, their salesperson, is so good. He visited the house several times throughout the entire process to make sure everything was just right, and he called me a lot. I just had my first annual service and maintenance visit and Brian called me that evening to see how everything went. It makes me feel comfortable and reassured knowing that they are there for me. Emergency service is included in the contract, and the one time I had to call for an emergency, someone was here within the hour. Miller's Heating & Air is an excellent mom-and-pop business. I give them five stars.
