What's Different About Cooling Mount Juliet Homes

We service homes across the 37122 area, from the neighborhoods off Mt. Juliet Road and Lebanon Road to the streets near Charlie Daniels Park and Old Hickory Lake. Most of these homes have the indoor unit in the attic, which works fine until the condensate drain clogs and water comes through the ceiling. Many have two systems, so one can fail while the other hides the problem for a while. Outdoor units on newer lots often sit in full sun, close to fences, shrubs or the path of the lawn mower, and they collect grass and debris. And a lot of the original builder-grade systems are now old enough that repairs come more often.

Signs Your AC Needs Repair

One floor is fine and the other is warm
Water stains on a ceiling under the attic unit
The outdoor unit hums but the fan doesn't turn, or it won't start at all
Ice on the refrigerant lines
Rooms feel cool but damp
The electric bill is noticeably higher than last summer

What a Visit Looks Like

Call or text and tell us which system it is and what it's doing. We check the electrical parts, refrigerant, airflow and drainage, including the drain pan and float switch in the attic. You'll know what's wrong and what it costs before we start. Capacitors, contactors and drain clogs are usually fixed the same visit, and we confirm the house is cooling before we leave.

Repair or Replace?

Most air conditioners and heat pumps last around 10 to 15 years. If yours is in that range and the compressor or coil fails, a replacement is often the better use of your money. If it's younger and the problem is a part, we'll fix it. If only one of your two systems needs replacing, we'll say so.

Honest Summer Tips

Check the attic drain line and filter in spring. A clogged drain is the most common cause of ceiling leaks we see.
Keep the outdoor unit clear, and point the mower's discharge away from it.
Hot upstairs rooms are common in two-story homes. Before buying new equipment, see our Mount Juliet heating and air page for the usual fixes.
If the system ices up, turn it off and call us. Don't keep running it.

Usually not, but don't wait long. The downstairs unit will work harder trying to keep up.
