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

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 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 am a highly skilled and experienced home service professional. I recently completed a job where I changed filters and tightened belts on a residential heating and cooling system. This involved removing the old filters, cleaning the coils, and replacing the belts. I also checked the system for any leaks and made sure it was operating efficiently.
Steve S.
I was called to a home to repair a central air conditioning unit that was not cooling. Upon arrival, I found that the thermostat was programmed backwards, causing the unit to run continuously. I diagnosed the issue and installed a new board system, which resolved the problem. The customer was very pleased with the service and thanked me for my help.

I was called to a home to install a new blower motor. The old motor was not working, so I replaced it with a new one. However, the new motor was not working either. I diagnosed the problem and found that the control board was faulty. I replaced the control board and the blower motor started working again.

This is an estimate to replace the blower wheel on a residential heating and cooling system. The labor is included in the estimate, and the parts are available. If you would like to move forward with this estimate and accept the terms, we will schedule the work. Thank you, Adam.
Calob B.
I was called to a home to address a problem with the heating and air conditioning system. Upon arrival, I found that the system was not producing enough airflow and the blower speed was too low. I added more airflow to the system and raised the blower speed, and the system is now running great.
James B.
I installed a roof top unit and a tenor heater for a customer. I removed the old unit and installed the new one, ensuring it was properly secured and connected to the electrical system. I also installed a tenor heater and connected it to the gas line. I tested the unit to ensure it was working properly before leaving the job site.
Calob B.
I am a skilled professional that works for a Dor-Mar Heating & Air Conditioning company. I received a call from a customer who reported that their air conditioner was running good but they could not find a leak. I arrived at the customer's home and performed a thorough inspection of the air conditioner. I checked the refrigerant levels, inspected the condenser coils, and checked the evaporator coils for any signs of leaks. After completing the inspection, I found that the air conditioner was not leaking. The customer was happy with the results and thanked me for my help.
cameron c.
I arrived at the customer's home and performed a comprehensive inspection of their air conditioning unit. I checked the temperature split, amps and ohms, wiring, pressures, and radon test. I also sprayed off the coil and checked for any leaks.
cameron c.
I arrived at the customer's home to perform an air conditioning service. I ran the unit in the air conditioning mode to check for a temperature split. I also checked the amps and ohms of both the indoor and outdoor units to ensure they were functioning properly. I checked the wiring and pressure on the outside unit to ensure it was working correctly. I also performed a radon test to check for any potential radon gas in the home.
Ron M.
I am a highly skilled home service professional who recently completed a job for a client. The job involved installing a new water heater in their home. I arrived at the client's home on time and began the installation process. I worked diligently to ensure that the installation was done correctly and efficiently. I also took the time to explain the features and benefits of the water heater to the client, ensuring that they were satisfied with their purchase. After the installation was complete, I cleaned up the work area and left the client with a satisfaction guarantee. The client was very pleased with the job and expressed gratitude for my professionalism and expertise.
