Mainstream Heating & Cooling

Since 1995, our family-owned team at MainStream Heating & Cooling has served homeowners and businesses in Clarksville, Montgomery County, surrounding Tennessee communities, and nearby parts of Kentucky. Our service area includes Woodlawn, Adams, Pleasant View, Palmyra, Cumberland Furnace, and Oak Grove, Kentucky. We provide 24/7 heating and cooling service, work on all brands, and help customers choose new HVAC systems based on the property’s size and layout, comfort needs, efficiency, budget, warranties, and long-term performance.

We believe excellent service involves more than the equipment we sell, install, and service. From the first phone conversation through a service call or installation, we put our customers’ needs first and focus on fast, quality work at a fair price. Our highly qualified technicians and installers handle complex diagnoses, repairs, and installations with the goal of delivering maximum comfort and value. Our team includes NATE-certified technicians, reflecting our commitment to high standards in heating, ventilation, air conditioning, and refrigeration service. We stand behind our repair work: if a repair is not fixed right, we will redo it at no charge. We also guarantee that equipment we install will perform as stated, or we will remove it and return 100% of the customer’s investment.

Our services cover heating, cooling, indoor air, refrigeration, and energy-saving comfort options. We are designated as a Certified Geothermal Installer and are certified by the International Ground Source Heat Pump Association to install geothermal heat pump systems. Whether our customers need help restoring a system, comparing replacement options, or considering geothermal heating and cooling, we focus on their needs and work hard to exceed their expectations. Our goal is to provide residential and commercial customers with dependable climate-control service, qualified diagnoses and repairs, and equipment options suited to their comfort needs and budgets.
