AC Installation and Replacement, Done Right
Bigger is not better with air conditioning. An oversized unit cools too fast, short-cycles and leaves the air clammy, while an undersized one never catches up. The right size starts with a load calculation of your home, not a rule of thumb.
We look at your ducts, your insulation and your windows, recommend a system that fits and install it with correct refrigerant lines, drains, electrical connections and a clean finish, then walk you through how to use and maintain it.
Music City Plumber brings ac installation and replacement to homes and businesses in Nashville and across 20 Middle Tennessee cities.

Questions About AC Installation and Replacement
Still have a question?
How long does installation take?
Many replacements are completed in a day or two, depending on the system and the ductwork. We give you a realistic timeline at your visit.
Should I replace the furnace and AC together?
Matched equipment often works better together, and replacing both at once can be efficient. We explain the options for your home.
Do I need new ductwork?
Not always. We inspect your ducts and tell you whether they can be reused, repaired or need replacement.
