An undersized or improperly matched furnace is one of the most common causes of uneven heating and high winter bills. Tri-State Heating & Cooling installs furnaces sized to your specific home, not a generic replacement — with most installs completed in one day or less.

A free in-home estimate and second opinion, with no-pressure guidance comparing your options and price points.
Proper load sizing based on your home’s square footage, insulation, and layout — not a swap of the old unit for a similar-sized new one.
Optional ductwork reconfiguration where it improves performance, paired with energy-efficient equipment backed by manufacturer and workmanship warranties.
Homeowners in Cincinnati’s older neighborhoods often deal with original ductwork never designed for a modern high-efficiency furnace, while newer construction in Mason, West Chester, and Kettering can be undersized for the actual heat loss of the home. Both situations call for the same thing: a proper sizing calculation before installation, not a swap of the old unit for a similar-sized new one. That’s the standard we install to.

How long does furnace installation take? Most installations are completed in one day or less, about 90% of the time.

Excellent customer service from the first service call to a quote to replace all duct work and move the system from our attic to the main level. Explained options available with all pros and cons and gave options for different price points and systems and why one vs another. We appreciate the professional install job and crew. I would highly recommend this company because they are trustworthy people doing their best work.
