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 Columbus’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. Columbus’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 Columbus 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.

I arrived at the customer's home to perform a routine maintenance check on their heating and cooling system. Upon arrival, I noticed that the thermostat was not working properly. I checked the wiring and found that the common wire was not connected to the thermostat board. I connected the wire and turned on the thermostat. The unit started up and the cooling and heating systems began to operate as expected. I tested the thermostat to ensure it was working properly and made any necessary adjustments. I also checked the air filters and replaced them if necessary. Finally, I cleaned the outdoor unit and checked the refrigerant levels. The customer was satisfied with the service and thanked me for my help.

I was called to a home in the suburbs to repair a dehumidifier that was not working properly. Upon arrival, I found that the duct was clogged with debris, which was preventing the dehumidifier from drawing in enough air. I removed the debris and cleaned the duct thoroughly, which allowed the dehumidifier to work properly again. The homeowner was very grateful for my help and expressed her satisfaction with the service.
Calob B.
I am a professional HVAC technician with Dor-Mar Heating & Air Conditioning. I was recently assigned to replace a furnace and water heater at a residential home. The job involved removing the old units, installing the new ones, and ensuring that everything was properly connected and functioning. I also took the time to clean up any debris and leave the area clean and tidy.
Trevon S.
I conducted a thorough maintenance visit on a residential air conditioning system. I started by asking the customer about any specific concerns they had regarding the unit. I then inspected the furnace filter and evaporator coil, checked the blower amp draw, and ensured proper airflow by examining the condenser coil's cleanliness. I also inspected the electrical components of the condenser for any signs of burnt or loose wires and verified the microfarad readings on the capacitor. Finally, I confirmed that the refrigerant pressures were within the correct range to guarantee optimal system performance. The unit was an old r22 system that was not in good shape. I did not hookup gauges to the system. I informed the customer that she should be prepared to replace the unit soon as it was on borrowed time.
Bryson A.
I am a highly skilled home service professional. I recently completed a job replacing the TXV and line drier for an evaporator coil. The TXV was under warranty, so I was able to get it replaced without any additional cost. The evaporator coil was also in need of repair, so I replaced it with a new one. The customer was very satisfied with the work I performed, and I was able to leave them with a clean and functioning HVAC system.
Calob B.
The customer had a clogged drain that was causing water to overflow into the furnace. I diagnosed the issue and determined that the control board needed to be replaced. I removed the old control board and installed a new one, and the furnace was working properly again.
cameron c.
I arrived at the client's home and performed a thorough maintenance check on the air conditioner. I checked the refrigerant levels, cleaned the condenser coils, and tested the electrical components. I also performed a radon test to ensure the air quality in the home was safe. Finally, I sprayed out the evaporator coil to remove any dirt or debris that may have accumulated.
Ron M.
The air conditioner was not cooling the house. I checked the system filters and found that they were clogged. I removed the filters and cleaned them. I also checked the system for leaks and found none. I checked the refrigerant levels and found that they were low. I added more refrigerant and the system started cooling the house again.
Garett F.
I was called to a home to inspect a heating and cooling system. Upon arrival, I noticed that the room temperature was rapidly rising. I inspected the attic and found that the insulation was insufficient, which was causing a high heat load for the system. I recommended that the homeowner install additional insulation to improve the system's efficiency and reduce energy consumption.
