Air Conditioning Service

If you’ve lived in Tennessee for a while, you know how important it is to have good air conditioning. We’ve been providing high-quality air conditioning service for many years, and we’ll be more than happy to bring our skills to your home. We install Trane air conditioners and service all makes and models.

Heat Pump Services

Given our area’s fairly mild winters, heat pumps are a highly efficient heating and cooling solution for many of our customers. They do require a fair amount of service, though, and the heating service team at Stanley Best Heating & Air, Inc. is up to the task. Contact us today if you need help with your heat pump.

HVAC Services


There’s nothing like a furnace to keep you warm and comfortable all winter long. Whether you have an oil or a gas furnace, we provide heating service for all makes and models. We also install a range of highly efficient Trane furnaces for residential and light commercial applications.

Ductwork Replacement

When you have central air or forced-air heat, a good duct system is essential. If your ductwork is old or in disrepair, we’re here to provide you with brand new and highly efficient ducts.

Indoor Air Quality

Indoor air quality isn’t just about people with asthma or allergies. It affects everyone in your home, even pets. We carry and install a broad range of IAQ products, including air cleaners, humidifiers and ventilators.

Ductless Mini-Split Systems

Some of the most efficient cooling systems available today are ductless mini splits. When you’re ready to go ductless, you need Stanley Best Heating & Air, Inc. to get your new system up and running within the same day of installation.

Geothermal Systems

When you’re ready to make a major long-term investment in your home climate control, put the power of geothermal energy to work for you. These systems deliver incredible energy efficiency by taking advantage of stable temperatures underground. We’re proud to install all types of geothermal heat pumps for home and business owners throughout our service area.

Controls & Thermostats

The products you use to control your heating and air conditioning systems are as important as the systems themselves. We proudly install a wide range of advanced controls, including programmable thermostats, home zoning systems and wireless thermostats.

Evaporator & Fan Coils

Your evaporator and condenser coils do all of the heavy lifting in your air conditioner, and as air conditioning service professionals, we can help. Contact us today for repairs and maintenance on your evaporator and fan coils.
