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 Hilliard’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. Hilliard’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 Hilliard 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.

Trevon was wonderful meet in appearance pleasant in personality wonderful experience overall
Job got done
Sam - Hilliard, OH 43026
Our hot water tank flush got done but the process was not smooth. This is the second year in a row that they have not notified a technician that we have a tankless system leading to delays in getting the job done. I have told scheduling both times I scheduled and the message does not seem to be relayed. Dave arrived during the appointment window. He did make a mess on the wall and floor with where the drain is located on the system. He did let me know what happened and grabbed one of our 5 gallon bucks to catch the water after. I was disappointed to find that after Dave left he left the puddle of water on the floor and the 5 gallon bucket stuck under one of condensation pipes I believe. It was a quarter of the way filled with vinegar and water. It took 2 bath towels to clean up his mess. Being 35 weeks pregnant, it was disappointing that he did not clean up after himself and I was left on my hands and knees on the cement slab cleaning up what he should have done. He didn’t even ask for a towel after causing the mess.
Response from Dor-Mar Heating & Air Conditioning:
We apologize for the mislabeling of your Job type Samantha, we have updated the system to show you have a tankless system. We will also be sure to have a conversation with the tech in regards to leaving a mess in your home.

Excellent service
Angel - Hilliard, OH 43026
Good service, but misdiagnosed the issue and the cost
Jesse - Hilliard, OH 43026
He showed up on time and was friendly, but said that the repairs would cost $4000.00 or I could just get a new furnace. The next repairman found the issue and repaired the furnace for $600.00.
Always great
Samantha - Hilliard, OH 43026
Dave is always thorough and explains what he is doing! We are happy to have him continue to work with us. Scheduling is also easy and quick.
