What does an HVAC Contractor do?
An HVAC contractor is a business whose service technicians are tasked with installing, maintaining, and repairing heating, ventilation and air conditioning systems. In the state of Ohio, a professional license is required for a company to perform these services. Learn More About HVAC Contractors
Heating Contractor
One of our primary services is to serve Canal Winchester’s needs as a Heating Contractor. The job of a heating contractor is to install, repair and maintain heaters, ventilation systems, and air conditioners. This includes associated equipment like ductwork, thermostats, furnaces, heat pumps and boilers. Some heating contractors offer additional services like performing energy audits, cleaning ductwork, installing indoor air quality equipment, or sealing ductwork.
The Best Heating Contractor Keeps Your Family Comfortable
If your heating equipment breaks, or is in need of any type of maintenance, repair, or replacement, a heating contractor is the right professional to reach out to. Find out more about Heating Contractors
Heating Equipment Supplier
In addition to maintaining and repairing heating equipment, furnaces and heat pumps, Dor-Mar offers replacement equipment. When it’s time to replace your heating equipment, it’s just as important to choose the right equipment supplier or installer as it is to choose brand, BTU, efficiency, and other elements of your system. If you are spending money to repair a heater that’s more than 10 years old, it might make more sense to replace it with a new, more energy-efficient furnace. Undoubtedly, the new system will use less energy simply because newer units include improved technology. Canal Winchester’s Top Heating Equipment Supplier

There are a number of review websites where you can read detailed descriptions of a particular homeowner’s experience. Often these sites also have a 1-to-5 star rating system. Look for a high review count (meaning the company has been around for a while or service a large number of customers) and a high average rating, no less than 4.5 stars. You can also see if the company is actively paying attention to, and responding to, consumer reviews.
Dor-Mar Heating and Air Conditioning has accumulated more than 1,000 reviews and has an average rating of 4.83 stars on Google. We make it a point to respond to every review, positive or (the rare) negative review. If something went wrong, we work to make it right.

Air Conditioner Installation and Replacement Canal Winchester Ohio
As your old A/C system deteriorates with age, it must work much harder to cool the air inside your home. This means it’s necessary for it to consume more energy to deliver the desired temperature. When you consider this and the significant difference in the energy efficiency of current air conditioning systems versus those manufactured only 15 or 20 years ago, it’s easy to see how switching to a new, state-of-the-art system will represent substantial savings on your energy bills.
Installing a new air conditioning system is not a job for a weekend warrior. The installation must be completed in accordance with local and state building codes and following the manufacturer’s specifications in order to protect your warranty. The job demands a licensed and trained professional like the ones at Dor-Mar Heating & Air Conditioning.

Bryson is great. He seems to really know his stuff and I feel confident that he did an excellent job. He and his partner even came early because I had mentioned to them I needed to make a community visit for work. He’s focused and has been here before so felt very comfortable.
Amazing service!

Amazing service!
Krista - Canal Winchester, OH 43110
In the extreme heat, our air conditioner went out. David went above and beyond and triple checked everything just to see if we could fix the problem without having to replace everything. He was super thorough and walked us through all the steps. In the end, we got a new unit and he arranged everything and provided us with multiple options. We were thankful for the education and for the wonderful customer service.
Zach S.
Leaking from turbidity sensor and wash motor. Needs new wire harness as well, harness is corroded from leak
Trevon S.
During the recent maintenance visit, we conducted a thorough evaluation of the air conditioning system. We initiated the session by inquiring about any specific concerns the customer might have had. The condition of the furnace filter and evaporator coil was assessed, and we recorded the blower amp draw. We also ensured proper airflow by inspecting the cleanliness of the condenser coil outside. Additionally, we examined the electrical components of the condenser for any signs of burnt or loose wires and verified the microfarad readings on the capacitor. Finally, we confirmed that the refrigerant pressures were within the correct range to guarantee optimal system performance.
