Heating & cooling in Alton
Alton's mix of historic river-town homes and newer construction keeps us on our toes. We service aging systems and install high-efficiency replacements throughout the area.
Built on the bluffs, built to last
Alton's original town plat dates to 1817, and a lot of its housing predates central heat and air by a century or more. Christian Hill sits on the bluff above the Mississippi with homes going back to the 1830s. The Middletown Historic District covers more than 600 buildings, many of them Federal, Italianate and Queen Anne houses from the 1800s. Further from downtown the housing runs newer, from postwar ranches to recent construction.
Old houses like these can be heated and cooled well, but the work is different. Ducts have to be routed through closets and attics that were never meant for them, outdoor units have to fit on steep or narrow lots, and river-valley humidity punishes any system that's oversized or short on airflow.
We make the run to Alton for repairs, tune-ups and full replacements, not just big jobs. If your heat or AC is out, call and we'll tell you when we can be there.

In most cases, yes. The challenge is the routing, not the equipment: running ducts through closets, attics and old chases without tearing up plaster, and finding a spot for the outdoor unit on a sloped lot. The right plan depends on the house, so we look at it in person before recommending anything.
Summer air in the river valley carries a lot of moisture, and an AC only removes it while it runs long enough. An oversized unit cools the house fast, shuts off, and leaves the humidity behind. A thermostat fan set to ON instead of AUTO can also put moisture back into the air. Checking sizing, airflow and fan settings usually points to the fix.
