Unionville is a community in northern Bedford County, between Shelbyville and the Rutherford County line. It has stayed rural, but it’s seen steady growth from people who want land and quiet within reach of Murfreesboro and Nashville.
That means two kinds of homes side by side: newer houses with heat pumps, attic air handlers and long duct runs, and older farmhouses with systems that have been patched over the years. Both get the same honest diagnosis.
Heating & cooling in Unionville
What Unionville homes ask of a system.
Newer construction
Builder-grade systems in newer homes often need drain, airflow and thermostat attention in the first years, before small problems turn into ceiling stains.
Attic air handlers
Equipment in a hot attic depends on a clear condensate drain and a working float switch. A clogged drain is one of the most common summer calls.
Wide-open exposure
Homes on open land take full sun in summer and full wind in winter. Sizing the system for the actual house matters more than the square-foot rule of thumb.
Rural power
Like much of rural Bedford County, the Unionville area is served by Duck River Electric. All-electric heat pump homes are common.
Unionville questions
Asked in Unionville.
Does Redeemer serve Unionville and northern Bedford County?
Yes, Unionville is in Bedford County, which Redeemer Heating and Air serves from Shelbyville. Call or text (931) 224-8403.
My newer Unionville home’s AC leaks water in summer. Why?
The most common cause is a clogged condensate drain or a full drain pan at the indoor unit. Turn the system off at the thermostat and call; clearing the drain and checking the float switch usually solves it.
Is my builder-installed system the right size?
Sometimes not. If the house is clammy, cycles on and off quickly, or has rooms that never keep up, sizing or ductwork may be the issue. A careful look at airflow and the duct layout is the place to start.
