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 Central Ohio’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. Central Ohio’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.
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.
Dor-Mar Heating & Air Conditioning has attained a track record as Westerville’s most reputable, trustworthy HVAC contractor. With offices and service technicians available throughout the metro Columbus, Newark and Zanesville areas, we bring responsive, family-oriented service to your door, frequently the same day.

Steven was able to come out a day after my capacitor and fan motor went out. He was able to get the unit up and running with parts stocked in his truck and got everything up and running in just a few hours. Really nice guy and was very helpful answering all my questions about A/C and how everything works.
Nicholas G.
Doug and Jeremy from Dor-Mar did an outstanding job. They worked tirelessly to remove our old (1960s era) HVAC system and install a brand new one. We’re so happy to have a working system again. They took care to ensure everything was done correctly and their attention to detail was impressive. They were meticulous during clean-up and we are thrilled with the result. They also took the time to teach me about the system and ensure I was 100% satisfied.

Review of Dor-Mar Heating & Air Conditioning
Just had my first experience with Dor-Mar today. David was out to fix an issue that was identified by the prior owner. He fixed the issue and was so efficient that he saved me some of the quoted labor! He also recommended some humidifier settings to run my system more efficiently. I signed up for their service program and was happy to hear that they would contact me to set up the preventative maintenance included versus me having to remember to schedule it. David was great and I’ll definitely be requesting him when scheduling future jobs!

Review of Dor-Mar Heating & Air Conditioning
This is our second experience with Dor Mar, both service calls have been exceptional. For this more complicated project, Dor Mar fit us in on very short notice to replace our furnace and ac unit. Perfect timing with this being a Midwest spring weather week with near freezing temps today and forecasted temps in the 80s for the end of the week. Cody Thompson was professional, knowledgeable and exceptional in working with his coworker, Brandon, to handle an efficient and effective installation.
