Heating and Cooling Services in Sullivan

Our heating and AC services include installation, maintenance, and repairs for a wide range of system types. As HVAC equipment ages, it loses efficiency and becomes more prone to breakdowns. We can install many types of heating and cooling equipment, including high-efficiency furnaces, boilers, and cold-climate heat pumps. We also install ductless systems, which are ideal for homes without ductwork.

To keep your new system operating effectively and efficiently, it needs regular professional maintenance. Schedule a tune-up for your heating system in the fall and for the cooling system in the spring. This allows time for any necessary repairs before you need the system full-time.

Our list of HVAC services includes:
  • AC repair
  • AC installation
  • Heating repair
  • Heating installation
  • Heating and cooling maintenance
  • Furnaces
  • Boilers
  • Heat pumps

Serving Sullivan and Nearby Areas

Temperature extremes in our area place extra stress on your HVAC and plumbing systems. Our average winter low is in the low-to-mid-20s, with cold snaps that can plunge well below zero. Older homes across Ashland County may lack sufficient insulation, pushing heating systems to their limits. It can also lead to frozen and burst pipes. However, regular maintenance and timely repairs help keep systems running smoothly and avoid costly breakdowns.

Frequently Asked Questions

Homeowners often have questions about our HVAC and plumbing services. Here are answers to the most common ones we hear.


Our HVAC services cover furnaces, boilers, heat pumps, central ACs, ductless systems, and indoor air quality equipment. For your plumbing system, we install water heaters, repair and replace fixtures, find and fix hidden leaks, and clear clogs. We can handle installation, maintenance, and repairs for all these home systems.

It’s best to schedule AC or heating repair services at the first sign of trouble. This prevents the problem from growing, which would then be more expensive to repair. For forced-air systems, the first sign is often low airflow or unusual cycles.

A common sign you need furnace repair service is hearing unusual or loud noises. You should also call if you notice a yellow or flickering pilot light. The rotten-egg smell of natural gas is a definite sign to evacuate and call for repair immediately.
