AC replacement and installation in Lebanon
Free replacement estimates from your Lebanon neighbors, with equipment sized for your house and installed to last.
If you are shopping for a new air conditioner in Lebanon, you will meet a lot of salespeople and very few explanations. We would rather explain. Heavenly Air installs and replaces central air conditioning across Lebanon and Wilson County, offers free estimates on complete system replacement and does not push equipment you do not need.
Because we work out of Lebanon, we see the same houses year after year: older homes around the square that have had two or three systems, newer subdivisions, large country houses on long lots and additions that outgrew their original equipment. Each one calls for a different approach.
Three Lebanon houses, three different installations
The older home near the square. Often built without ductwork and retrofitted later, with ducts squeezed through tight attics. The new system can only perform as well as those ducts allow, so we inspect and, where needed, repair or modify them as part of the job.
The big house on a country lot. Long duct runs and long refrigerant line sets, often two systems. Sizing and duct design matter more than the equipment brand, and we plan the routing before we order anything.
The house with the addition. The bonus room, sunroom or finished attic added load the original system was never sized for. Sometimes the answer is a second small system rather than one larger one.
How we size a replacement
We do not copy the old unit’s tonnage. We look at square footage, insulation, window area and orientation, ceiling height, the ducts and how the home is used, because an oversized system short cycles and leaves a house humid, and an undersized one never catches up. Efficiency is rated in SEER2, and staged or variable-speed equipment cools more evenly and manages humidity better at a higher price. We explain what each option buys you so you can decide.
What is included in a complete installation
Our installations are clean, code-compliant and backed by a 10-year parts and labor warranty on new installations:
- Reviewing the house and ductwork before choosing equipment
- A level, stable pad and proper clearance for the outdoor unit
- A matched indoor coil and a correctly sized line set
- Evacuating and charging the system to manufacturer specifications
- A properly sloped condensate drain with a safety switch where needed
- Safe electrical connections and a compatible thermostat
- A full test, a walk-through of the controls and cleanup
What drives the price
System size and efficiency, single-stage versus staged or variable-speed equipment, the condition of the ductwork, how hard the installation is to reach, and electrical and thermostat needs. We give written estimates after we have seen your system. Estimates on complete replacement are free, and financing is available for residential and commercial projects. See our financing page.
Replace now or wait for summer?
If your system is more than 12 to 15 years old or already needs a repair, ask for a replacement estimate now. Spring and fall are the best times to replace, when schedules are open and you are deciding on your own terms instead of in a heat wave. Our Lebanon AC repair team can give you both numbers on the same visit.
AC Installation & Replacement in Lebanon: common questions
How long does a replacement air conditioner last in Lebanon?
Most central air conditioners last about 12 to 15 years in the Southeast, longer with regular maintenance.
Can you replace just the outdoor unit?
Sometimes, but the indoor coil, line set and thermostat need to match for the system to perform and keep its warranty. We evaluate that on the estimate.
Do I need new ductwork with a new air conditioner?
Not always, but leaky or undersized ducts limit any new system. We inspect the ducts and tell you what, if anything, should be done.
Is there a warranty?
Yes. New installations come with a 10-year parts and labor manufacturer’s warranty.
