AC installation and replacement in Mt. Juliet

Sizing matters more than brand in a humid climate

The most common installation mistake in Middle Tennessee is an oversized system. It looks like a good idea, since bigger sounds safer, but a unit that is too large cools the air quickly, shuts off before it has run long enough to remove moisture and cycles on and off all day. The result is a house that is cool but clammy, and a compressor that wears out early.

Near Old Hickory Lake and J. Percy Priest Lake that effect is amplified. We size a replacement from your home, not from the label on the old unit. We look at square footage, insulation, window area and orientation, ceiling height, the ductwork and how the house is actually used.

Common Mt. Juliet replacement situations

Every house is different, but these are the cases we run into again and again:

• Builder-grade systems at the end of their life. Homes built during Mt. Juliet’s growth years often came with standard-efficiency equipment that is now 12 to 18 years old.
• Bonus rooms over garages and vaulted ceilings. These rooms are hard to cool, and sometimes the answer is ductwork changes or a staged system, not a bigger one.
• Systems that still run R-22 refrigerant. Repairs get expensive because that refrigerant is no longer produced.
• Additions and finished attics. New square footage changes the load, and the old system was never sized for it.

What a complete installation includes

A good installation is more than swapping boxes. Our process covers:

• Reviewing the house and the ductwork before the equipment is chosen
• Setting the outdoor unit on a level pad with proper clearance
• Matching the indoor coil and connecting a correctly sized line set
• Evacuating and charging the system to the manufacturer’s specifications
• Running and sloping the condensate drain correctly, with a safety switch where needed
• Making safe electrical connections and installing a compatible thermostat
• Testing the system, walking you through the controls and cleaning up

Efficiency, comfort options and cost factors

Efficiency is rated by SEER2, and higher ratings use less electricity. Staged and variable-speed equipment runs longer at lower output, which controls humidity better and runs quieter, at a higher price. The ductwork, the size of the house, how hard the attic is to access and any electrical work all affect the final number, which is why we give written estimates after seeing your system rather than quoting by phone.

Free estimates are available on complete system replacement, and we offer financing for residential and commercial projects. See our financing page.

How long installation takes

A straightforward replacement is often completed in a single day. Projects that include new ductwork, additional zones or electrical upgrades take longer, and we give you the schedule before we start. Permit requirements vary by city and county, and we handle them as part of the job.
