Top Notch Air Conditioning and Heating Install and Replacement in Hartsville and Middle Tennessee
If your HVAC system is not heating or cooling properly, needs frequent repairs, or is more than ten years old, it may be time to consider replacing it. At Top Notch, we take both your indoor comfort needs and budget into account before recommending a new system. We evaluate the cooling load to ensure that equipment is sized correctly and look at existing ductwork to ensure air will circulate efficiently.
If you have added on to your home or experience uneven temperatures throughout your home, there are solutions. Ductless mini-split heat pumps and air conditioners can be used to augment a ducted system or provide conditioned air for spaces that are difficult to connect to ducts.If you need a new air conditioning installation in your Greater South Nashville area home, Top Notch Building Group provides new AC and furnace installations, upgrades and replacements.
Energy-Efficient A/C and Heating Equipment
A modern HVAC system can enhance comfort while reducing energy use. Dual- and multiple-stage heat pumps and air conditioners from American Standard and other high-quality manufacturers use less energy to operate and provide excellent humidity control. Ductless units can be turned off without affecting temperatures in other rooms. Zoned systems allow precise climate control for different parts of your home. Geothermal heat pumps use up to 70% less energy.
After installation, we support our work to maximize the life of your new system. Our scheduled repair, emergency repair, and preventive maintenance services keep you comfortable all year long.



Importance of Proper Installation
According to the Department of Energy, improper installation is a major factor in poor performance, increased repairs and early system failure. Undersized units run for long periods. Oversized units reach the set temperature quickly and switch off without removing humidity, leaving rooms feeling clammy. Both oversized and undersized units break down more often and can reduce efficiency by up to 30%.
Factors affect the sizing of a new system include:
- Square Footage
- Room Configuration
- Building Orientation
- Number of Door & Windows
- Amount of Installation
- Landscaping & Shade
