Quick answer
Comfort Air Solutions works as an HVAC contractor in Franklin, OH, about 15 minutes south of our Miamisburg shop on I-75 or Dixie Highway. We repair and replace furnaces and air conditioners, clear iced PVC vents and frozen condensate lines in winter, test older chimneys for CO, and protect equipment in damp river-town basements.
Franklin sits on the Great Miami River just over the Warren County line and was settled in the 1790s, making it one of the oldest towns in the region. The historic downtown blends 19th-century storefronts with the houses that grew up around them, while newer subdivisions have filled in toward I-75 and SR 123.
From Miamisburg we reach Franklin in about 15 minutes, straight down I-75 or Dixie Highway. That’s close enough for same-day service most days and quick dispatch on winter emergencies.
Franklin homes and the HVAC problems we see
Older homes, damp basements
Around the historic core, many homes are 1900s–1940s frame and brick houses with basements that take on moisture each spring. Damp basements are hard on furnaces: rusted burners, corroded blower housings and control boards that fail early. A raised furnace pad and a basement dehumidifier can add years to the equipment.
Mid-century ranches and 1990s houses on the outskirts have more routine problems — aging AC coils, tired blower motors and filters overdue for a change. For any of them, our furnace repair and replacement work starts with a proper diagnosis, not a guess.
Summer is the other stress point. The river bottom around Franklin holds heat and humidity on still July evenings, and older condensers with weak capacitors or dirty coils give up when the house needs them most. A spring check of amp draw, refrigerant charge and the condensate drain heads off most of those calls.

Local to Franklin
We work throughout Franklin — near Franklin High School, along Dixie Highway, around the historic downtown, and in the homes across the river toward Carlisle. Springboro sits just to the east, and many Franklin families shop and commute along SR 73.
Franklin’s newer growth sits on the east side of town toward I-75 and the SR 123 interchange, where 1990s and 2000s subdivisions have attic ductwork and builder-grade equipment reaching replacement age. On those homes the conversation is less about rust and more about crushed flex duct, undersized returns and whether a two-stage furnace would even out the upstairs.
A typical winter call
After a hard freeze followed by a quick thaw and another freeze, a high-efficiency furnace in Franklin stops heating and flashes an error code. Often the PVC intake or exhaust outside has been blocked by ice or a drift, tripping the pressure switch, or the condensate line has frozen. We clear it, check the drain, and suggest a raised termination if it keeps happening. When it’s the middle of the night, our emergency furnace repair line is staffed.
A practical HVAC guide for Franklin homeowners
Franklin was laid out in 1796 and took a hard hit in the Great Flood of 1913, which is why the Miami Conservancy District now maintains several miles of levee through town. Most of the city, including the downtown business district, sits on the east bank of the Great Miami. Where your house sits relative to the river, and when it was built, says a lot about what its heating and cooling will need.
Franklin by area and era
| Part of town | Typical house | What we watch most closely |
|---|---|---|
| Around the historic downtown | 1900s–1940s frame or brick with a full basement | Basement moisture, rusted burners, shared or oversized chimneys |
| Lower ground near the levee | Older homes and small ranches | Sump and condensate drainage, furnace height off the floor |
| Mid-century streets off Dixie Highway | 1950s–70s ranches | Blower wear, small returns, second- or third-generation equipment |
| East side toward I-75 and SR 123 | 1990s–2000s two-stories | Attic flex duct, upstairs comfort, builder-grade replacements |
A winter checklist for high-efficiency furnaces in Franklin
River fog, freezing drizzle and quick thaws are hard on the white PVC pipes a condensing furnace uses. A few minutes after each storm prevents most lockouts:
- Check that both the intake and exhaust pipes outside are clear of snow, ice and blown leaves, and keep drifts shoveled back at least a foot.
- Look for a long icicle hanging off the exhaust; if it reaches back toward the pipe opening, knock it off gently.
- If the condensate line runs to a pump or an outdoor drain, make sure it is not frozen where it leaves the house.
- Know where the furnace error-code light is and take a photo before calling, so the technician arrives with the right parts.
Planning replacements before the rush
A lot of Franklin’s east-side equipment was installed within the same few years, so many neighbors hit replacement age together. Booking the estimate in March or October, rather than during the first heat wave, gives you time to compare complete system replacement options and pick an install date that suits you.

Why Franklin residents choose Comfort Air Solutions
Closer than most of our own county
Franklin is a straight shot down I-75, nearer to our shop than Huber Heights or Clayton. That short drive matters on a February night when a furnace has locked out on an iced-over intake pipe.
Basement-savvy furnace care
In the 1900s–1940s houses around downtown, spring groundwater and river humidity rust burners and control boards. We look for corrosion on every visit and suggest raised pads or dehumidification before damage spreads.
Chimney and venting safety in older homes
When a furnace moves to PVC, the old masonry flue often gets left to a lone water heater. Our combustion analysis and draft testing catch that before it becomes a carbon monoxide problem.
Home-warranty friendly
If your Franklin home is covered by a home warranty, we work with those companies, explain the diagnosis in plain English and keep the paperwork moving.
