Quick answer
If you're looking for an HVAC contractor in Lebanon, OH, Comfort Air Solutions fixes and replaces furnaces, central air and heat pumps from the Federal-era blocks around the Golden Lamb out to the 1990s and 2000s neighborhoods near I-71. The drive from Miamisburg runs about 30 minutes, and our emergency line never goes to voicemail.
Lebanon wears its history openly. The Golden Lamb has welcomed travelers on Broadway since 1803 and is known as Ohio's oldest continuously operating inn, and the blocks around it are lined with Federal, Greek Revival and Victorian homes. Drive a few minutes toward I-71, though, and you're among subdivisions built in the 1990s and 2000s, their basements full of builder-grade equipment.
Comfort Air Solutions serves both halves of the city from our Miamisburg shop, about 30 minutes southeast. The same technicians handle a brick house downtown and a two-story off SR 48; the diagnosis just heads in different directions.
Lebanon homes and the HVAC problems we see
Two very different sets of HVAC problems
| Historic core near Broadway | Newer neighborhoods toward I-71 | |
|---|---|---|
| Typical era | 1800s to early 1900s | 1990s to 2010s |
| Common equipment | Converted gravity or older forced-air furnaces, window units, a few boilers | Original gas furnace with a matched split AC, now 15–30 years old |
| Frequent issues | Undersized ducts, uneven floors, uninsulated attics | Tired blower and inducer motors, leaking coils, noisy condensers |
| Usual fix | Duct redesign, ductless zones, careful furnace replacement | Right-sized system replacement |
In the newer homes, the conversation often turns to complete HVAC system replacement. Many original systems were sized by rule of thumb, so we recalculate with a Manual J before recommending anything. An oversized AC short-cycles and leaves a finished basement clammy in July; the right size runs longer and pulls more moisture out of the air.

Local to Lebanon
Lebanon, street by street
Our techs know the city: the historic district around Broadway and Main, neighborhoods near Lebanon High School, homes out by the Countryside YMCA, and the subdivisions off SR 48 and SR 63 heading toward the interstate. The Lebanon Mason Monroe Railroad's excursion trains leave from downtown, and when December's Horse-Drawn Carriage Parade fills Broadway we plan routes around the crowds.
A typical call from one of those 2000s-era neighborhoods: the furnace starts, the inducer motor hums, and then everything shuts down on a pressure-switch fault. Sometimes the inducer itself is failing; just as often a condensate trap clogged with debris is backing water into the switch hose. We clear or replace what's needed, test combustion, and — when the equipment is nearing retirement anyway — lay out repair and replacement options side by side, frequently priced right there in the basement.
Homes that went up during a building boom often still carry drywall dust and sawdust in their trunk lines. If your filters load up fast or registers leave a gray film, professional air duct cleaning is worth a look. We also cover nearby Mason and Waynesville on the same routes.
A Lebanon homeowner's guide to heating and cooling
Lebanon has a few conditions most of its neighbors don't share: a city-run electric department that has been operating since 1895, a historic core where houses change hands for their character, and a ring of 1990s and 2000s neighborhoods whose original systems are all reaching the end of their service lives around the same time. Here is how we would plan around each one.
Buying or selling in Lebanon: what inspectors flag
Home inspectors working Warren County tend to write up the same HVAC items in Lebanon listings. Knowing them in advance lets a seller fix the cheap things and gives a buyer realistic numbers before negotiating.
- Data-plate age. An original 1998 furnace or AC in a subdivision off SR 48 almost always gets flagged as near end of life, even if it runs fine.
- R-22 equipment. Older condensers use a refrigerant that is no longer produced, so a leak repair on one of those is a very different conversation than on a newer unit.
- Chimney venting in the historic district. An inspector will note a gas water heater left orphaned in an oversized masonry chimney after the furnace was changed to a PVC-vented model.
- Rust in the drain pan or a wet secondary line. Both suggest the coil has been sweating into the pan for years.
- Missing service records. A written tune-up report from the last year answers a lot of buyer questions before they are asked.
City electric service and your outdoor equipment
Because the city buys bulk power through American Municipal Power and runs its own distribution lines, any rebate or time-of-use question for a heat pump goes to the city's electric department, not a large investor-owned utility. Summer thunderstorms still bring brief outages and flickers anywhere. Our techs check contactors for pitting and capacitors for weak readings during a spring visit, since a compressor restarting against a failing capacitor after a power blink is a common way to lose one in July.
Planning for the subdivision replacement wave
When several houses on a Lebanon street were built the same year, their furnaces and air conditioners tend to fail in the same few seasons. If your neighbors are replacing, use a fall visit to get an honest read on yours and compare heating repair against a planned system replacement before a January breakdown forces the choice.

Why Lebanon residents choose Comfort Air Solutions
Right-sizing the builder-grade systems
Subdivisions off SR 48 and SR 63 went up fast, and many got whatever tonnage the builder stocked that month. We load-calculate before replacing, which is why a new Bryant system in those houses usually ends up the same size or smaller than the old one, not bigger.
Respect for Greek Revival and Federal interiors
Near Glendower and the courthouse, original woodwork is part of a house's value. Shoe covers, drop cloths and a careful plan for every penetration are standard on our crews, and reviewers regularly mention the cleanup.
Options priced at the kitchen table
When a Lebanon system is at the repair-or-replace line, you see both paths in writing, often with several equipment tiers quoted on the spot. Replacement quotes are free, and financing is available with approved credit.
Care for older residents
Plenty of Lebanon homeowners are retirees for whom a cold house is a health risk. Our phone is answered every hour of the day, and Fan Club members get priority scheduling when a repair can't wait.
