Serving Columbus Ohio Since 1962

HVAC Contractor

Dor-Mar is one of the highest rated HVAC contractors in Central Ohio. In business since 1962, we consider our customers the most important part of our business, and it shows in our online ratings.

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.

Air Conditioner Installation and Replacement

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.

See What Our Happy Customers Are Saying…

We've been satisfying loyal customers since 1962.

"It was so great to talk to Cindy in my time of crisis. 😉 She scheduled someone to be out to my house on the same day as my call, even during this busy season of AC repairs. She made sure I was informed of all the details and benefits of their call-out service including annual inspections on my AC, furnace, and water heaters. It adds real value to the call-out fee. In a separate review, I rated Garett who took care of my AC repair, but I also want to recognize Alexandria who received and addressed a simple follow-up question I had. Well-done all around and thank you all!"

"I wanted to wait on writing my review until our journey with Dor Mar was complete. Brian helped us first, evaluating an old furnace + AC unit at a home we recently purchased. He gave us an honest assessment of our options (repair vs replace,) and we went with a new system. He gave us good advice and helped us choose a system that was right for our budget and home. Matt and Steve removed the old system and installed the new. Like Brian, they were incredibly courteous and professional. Both were knowledgeable and helped teach me about the new system. Brandon came out a week, or so, after the installation to do a quality check of the new system. He was also incredibly helpful and offered sound tips on air flow and balancing it in order to heat/cool our home evenly. Everyone I've spoken to over the phone has also been courteous and knowledgeable. I'd recommend Dor Mar to anyone in need of heating/cooling help!"

"Brian was great! He called before coming to our house, very courteous, asking if 20 minutes was enough time. Arrived within time stated and took time to acknowledge/ pet our dogs, making them feel comfortable. He then went on to explain what he was doing, walked me thru the process as he went along and even waited to check results of his fix. He suggested a few extra services but was not pushy. Overall pleasant experience!"
