AC Installation in Cincinnati & Dayton, OH
Whether you’re replacing an aging system or cooling your home for the first time, Tri-State Heating & Cooling designs and installs AC systems sized specifically for your home — not a one-size-fits-all box off the truck. Most installations are completed in one day or less.
HOW WE DO IT
What's Included in Your AC Installation
Free In-Home Estimate & Second Opinion
A free in-home estimate and second opinion, with no-pressure guidance comparing your options and price points.
Proper Load Calculation & Sizing
A full load calculation so your new system is sized correctly for your home — not a one-size-fits-all box off the truck.
Ductwork Reconfiguration & Efficient Equipment
Optional ductwork reconfiguration to maximize efficiency, paired with energy-efficient equipment backed by manufacturer and workmanship warranties.
Built for Ohio Valley Homes
Homes across Cincinnati, Dayton, and the surrounding suburbs vary a lot in age and layout — a newer build in West Chester or Mason has very different airflow needs than an older home in the city with original ductwork. We size and, when needed, reconfigure ductwork to match your specific house rather than defaulting to whatever was there before, which matters even more given how demanding Ohio Valley summer humidity is on an undersized system.

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.
