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.

We've been satisfying loyal customers since 1962.

My furnace stopped working and I called this company. My call was taken right away in the middle of the night. I was told someone would be here mid morning. The gentleman called to let me know they were on their way. Once arrived they went straight to work found my issue and fixed it quickly. They were in and out within an hour and had my furnace working properly.

Allen ( your technician)came out and saved us alot of cold days and nights. We have American Home Shield and they sent a technician out 3 times replacing parts and still not fixed. The last technician said we need a new furnace. My furnace is only 5 years old . I thought he was lying and we decided to pay out of our pocket for a second opinion. Wow he saved us. Come to find out the last technician who said we needed a new furnace purposely switched wires on a pressure switch. Allen quickly found the problem and we now have heat . Please give Allen a fantastic review. He's a trust worthy man and professional.

Cory exceeded any expectation I had. Period! I had an issue with my AC system and called Dor-Mar around 11 am and got an appointment for next day. The representative was outstanding, extremely friendly and polite, concerned about the issue (and my health!!!) even if it was the first time ever i had contacted them. By 4 pm on the same day I got a call from Cory saying he was around and asking permission to visit and have an idea on ehat was going on. Not long ago he was leaving with the problem solved and my AC back to action. It was the first time I saw such great attitude and efficiency at the same time. Thank you, Cory and congratulation to Dor-Mar for keeping up with high standards on customer service and attention.
