Heating & cooling in Collinsville
From Uptown and Main Street to the neighborhoods on both sides of the county line, we keep Collinsville homes comfortable year round with honest repairs and clean installs.
Uptown character, newer neighborhoods all around
Collinsville is a city of about 24,000 that spans two counties, mostly Madison with parts in St. Clair. Uptown and the streets around Main hold many of the older homes, and newer neighborhoods fill in the rest of town. Plenty of houses here have also been added onto over the years, which matters more for heating and cooling than most people expect.
An addition is usually tapped into ductwork that was sized for the original house, so the new room ends up starved for air and the old rooms lose some of theirs too. Older systems that came with the house are often running well past their expected life. Both show up as hot and cold rooms and higher bills long before anything actually breaks.
Route 159 runs from our Edwardsville base through Glen Carbon straight into Collinsville, so we're a quick trip away. Most repair calls here are handled the same day.
Questions from Collinsville
Yes. If you have a Collinsville address, you're in our service area, whichever county you're in. Route 159 makes it a quick trip from our base in Edwardsville, and most repairs are handled the same day.
Most additions are tied into ductwork that was sized for the original house, so there isn't enough air left over to keep the new room comfortable. Sometimes balancing plus a dedicated supply or return run fixes it. If the system is now undersized for the whole house, we'll tell you that too.
Common signs: the AC runs but blows cool instead of cold, ice forms on the copper line or indoor coil, or you hear a hiss near the unit. Refrigerant doesn't get used up, so if it's low there's a leak. Topping it off without finding the leak only buys a little time.
What Metro East neighbors say

"Dan provided the best and quickest service possible. Our AC went out on a hot summer day and the company we'd booked canceled on us, and Dan got us up and running again."
"Dan is genuinely the best HVAC guy I've worked with. He's fixed multiple things at my house with no problems since. If you want a fair price with workmanship and pride behind the work, this is your guy."
