Locally Owned, Family Operated

Stay Cool Climate Control was founded by Jeremy Wolfe in 2018 and is still independently owned and funded.  A lifelong O’Fallon resident, he runs the company alongside his brothers, Carter (operations) and Cole (service technician), with their father Eric supporting homeowners through the sales department.

Over the years, Jeremy has built a team of the most trusted professionals in the heating and cooling industry, bringing in experts across all necessary fields. Together, they continue to grow and expand the services offered, ensuring homeowners receive the best solutions for every comfort need.
 
We are available 24 hours a day for all heating and cooling repairs, replacements, rehab projects, new construction, and specialty jobs outside the standard HVAC scope. If there’s a way we can help, we will.
 
Stay Cool offers maintenance memberships, free system replacement estimates, and free heating & cooling inspections on newly purchased homes for current customers.
 
Our team also completes 100+ hours of continued education every year and is fully licensed, bonded, insured, and certified in refrigeration and gas.
