Corcoran & Harnist Heating & Air Conditioning Inc

Based in Cincinnati, Ohio, we provide comprehensive heating, ventilation, and air conditioning services for residential and commercial properties. With more than 44 years in the heating and cooling industry, we bring practical experience to projects of all sizes. Our services include installation, repair, maintenance, and replacement for heating and air conditioning systems, as well as ductless and geothermal heat pumps. We also offer indoor air quality solutions and 24/7 emergency HVAC assistance.

We believe good service begins with listening. When you schedule an appointment, we ask about your indoor comfort goals, discuss your needs, and arrange a date that works for you. From there, we recommend practical options that fit your property, preferences, and budget. We work with established brands such as Carrier® and help you compare heating and cooling systems so you can make an informed choice for your home or commercial property. Our employees are trained in current HVAC installation and maintenance techniques to help each project proceed smoothly and each system perform as expected.

For commercial customers, we install and repair HVAC systems and rooftop units, service commercial refrigeration equipment, and provide energy management, building automation, and indoor air quality solutions. Our geothermal heat pump services include system design, installation, repair, and maintenance, with our technicians helping determine an appropriate solution for each property. After installation or repair, our service plans can help keep equipment operating at peak efficiency. Throughout every project, our focus remains on responsive, professional service and personalized solutions designed around your comfort needs.
