Lemont's housing, from limestone-era homes to new construction
Lemont is one of the older towns in the area, settled in the 1830s. It grew up along the Illinois & Michigan Canal and became known for its limestone quarries, and the historic downtown still shows it. Since then, the village has spread up the bluffs into newer neighborhoods and golf course communities. That range of ages means very different HVAC needs from one street to the next:
The homes we work in most:
- Older homes near downtown. Houses built before modern ductwork was standard may have converted gravity systems, boilers, small or undersized ducts, or no central air at all. Ductless mini-splits are often the best way to add cooling without opening walls.
- Mid-century and '70s–'90s homes. These are often on their second or third furnace and AC. Many systems are 15–20 years old now and need more frequent repairs.
- Newer two-story homes and subdivisions. Larger floor plans often have hot upstairs bedrooms in summer. Airflow balancing, zoning or a ductless unit can fix it.
- R-22 air conditioners. Systems made before 2010 may use R-22 refrigerant, which hasn’t been produced or imported in the U.S. since 2020 (EPA). Leak repairs on those systems get expensive.
- Hills and bluffs. Homes set into slopes often have walk-out basements, and the lower levels and upper floors can be very different temperatures.
Boilers and radiators in Lemont's older homes
It’s common for older homes near a historic downtown to have been built with hot water or steam heat instead of forced air. If your Lemont house has cast-iron radiators or baseboard heat, a boiler is doing the work, and it needs different care than a furnace.
We service boilers as well as furnaces. Common calls in older Lemont homes include:
- Radiators that stay cold or heat unevenly. This is often trapped air or a circulation problem, and it can usually be fixed in one visit.
- Pressure and relief-valve problems. A boiler that keeps losing pressure, or a relief valve that drips, should be checked before it becomes a bigger issue.
- Aging controls and circulator pumps. Replacing a failed part is often far cheaper than replacing the whole boiler.
If you want to add central cooling to a radiator-heated home, you don’t have to tear open walls for ductwork. A ductless mini-split from Rheem or Durastar can cool the main rooms, or the hot upstairs bedrooms, while your boiler keeps heating the house in winter.

Replacing a furnace or AC in Lemont, done right
When repair no longer makes sense, we’ll give you an upfront quote with options instead of a single take-it-or-leave-it price. Every replacement includes:
- A load calculation. Lemont homes vary a lot, from compact older houses to large two-story homes set into hillsides. We size the new system to your house, not to whatever unit was there before.
- All brands installed. We carry Rheem and Durastar and install all major brands.
- Haul-away of the old equipment, so nothing is left in your garage or basement.
- Flexible financing, so a failed system doesn’t have to wreck your budget.
We’re licensed, bonded and insured, and we’re a women-owned, family-operated business based next door in Bolingbrook.
