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 Granville’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. Granville’s Top Heating Equipment Supplier

Did you know that most consumers view online reviews as reliable as a personal recommendation? 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 Granville 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.

Excellent
Rick - Granville, OH 43023
Very professional and courteous.
The only tech I'd like coming to my house!
Jim - Granville, OH 43023
Steve was the 5th technician to come look at our AC unit and our whole-house dehumidifier. Every other tech from Dor Mar said they were unable to service our units due to access. They were all young and didn't know enough about how to solve issues. Steve not only did what it took to get to our (admittedly) difficult to reach air handler in the attic, but he went the extra mile to figure out exactly what was wrong with the dehumidifier, and didn't trust that just because it seemed to be running, that it was fixed. He listened to me when I explained what was going on and took the unit apart to really figure out what the issue was - it's what you expect a tech to do!! And he kept the cost reasonable in the process. I would request that his and only his name be who comes next time. The other techs wasted my time waiting for them during 5 different service call windows by not knowing how to figure out our situation. I hope he's able to train the next guys coming up!
Quick Response and Fix
Dustin - Granville, OH 43023
Response time was very fast and the fix was very quick. Charges seemed a little high considering tech was on site for 10 minutes but pretty par for the course these days.

Derrick B.
Showed up to no cool call, customer stated that after they changed the filter, their system would not run properly. Showed up and found that it was a DC communicating system, and that airflow from other filter was causing ICB to not want the compressor to kick on, Erased code, ran system, and system ran flawlessly for client.

Set up thermostat and walked customer through it. Hooked up humidifier without any new parts.
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.
