Collier's Heating & Air Conditioning

We’ve served North Central Indiana since November 1987, providing residential and commercial heating, air conditioning, and indoor air quality services. Our roots began in Warsaw when Joe Collier and Ken Diekoff purchased a Lennox dealership. More than 30 years later, we remain committed to quality service, competitive rates, and customer satisfaction. Our experienced technicians are NATE certified and dealer trained, giving our customers knowledgeable support for their home and workplace comfort needs.

For homeowners, we install and service comfort systems, provide indoor air quality solutions, and help customers explore geothermal options. Our commercial capabilities include complete heating and air conditioning installations, repairs available day or night, rooftop units, and indoor air quality services. We also service commercial refrigeration equipment, including walk-in coolers and ice machines. Whether we are helping with a residential system or handling the demands of a commercial property, we bring practical experience to every job.

Our services extend beyond conventional HVAC. Through our separate Fireplace Shoppe, we offer wood-burning, gas log, and pellet fireplaces, along with parts, accessories, barbecue grills, and outdoor furniture. We also provide fireplace cleaning, repair, and replacement services. For customers interested in using solar energy, our solar specialists install solar panels and solar attic fans. These attic fans help remove superheated air during the summer and can help protect the roof during the winter. From heating, cooling, and indoor air quality to geothermal systems, solar energy, fireplaces, and commercial refrigeration, we are here to help our customers make informed choices about comfort and energy savings.
