All County A/C & Heating is run by a father-and-son team. Patrick Dennis has been in business for more than 30 years and is the Assistant Dean at Nova Community College for HVAC. His son James Dennis has been working as an HVAC technician for more than 12 years.

Together, we have grown the business to what it is now. All employees have completed the HVAC program and are working towards an associate's degree in the Natural Science Department.

We offer a variety of maintenance services designed to address your unique needs, and our rates are among the most competitive in the industry. Contact us today for an initial system checkup and get the peace of mind that comes from knowing your heating and air conditioning system is working as effectively and efficiently as possible.

"A few weeks ago, you educated and helped me... over the phone! I need to thank you and want to buy you lunch as a thanks. More importantly, I don't know you but operating from good intent and your heart helps me in an enormous way!"

Thanks Again,
