Heating and Air Conditioning Service, Repair and Installation Services You Can Rely On

Serving Central 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

Central Ohio’s Highest-Rated Air Conditioning Contractor

Air conditioning contractors install, repair, and maintain the central air conditioning equipment, ductwork, electrical equipment, and controls found in residential and commercial cooling systems.

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.

Contact the most trusted Air Conditioning Contractor in the Central Ohio area.

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.

Contact us for a free estimate for replacement air conditioning equipment.

Jayden was delightful and courteous. I ended up needing a new control board that they could order and with labor would have cost me $600. I found one on Amazon for $250 and can do it myself. I don’t have anything bad to say, just got the part myself and can do the labor too is all. Otherwise, great customer service and promptly got me on the schedule. I would call them again if I needed to. ☺️

Anthony from Dor Mar came out to check an unusual problem I have in my condo. While ultimately unable to help due to the issue not being something they handle, Anthony got me one step closer to a solution by recommending another company. He was knowledgeable and a very nice young man to work with. I would definitely use Dor Mar in the future and would request Anthony.

Excellent service at a fair price. Anthony Payton was our tech and was probably one of the nicest guys you could meet. Highly recommend
Update: (Original post below)Service help called me and resolved the issue with being provided a service i didn’t want. They refunded the 216 to my card and I was able to pay the technician the way I wanted to, but admittedly still paid with my card as it ended up being $130 total and I didn’t just want to charge my card $5 with $125 in cash. Technician was awesome and the other service operator was very helpful. Dor Mar will continue to have my service as they promptly resolved the charge/billing issue as well as my heating/cooling issue right away. Thanks again for doing the right thing as well as being an awesome company to work with.Original 2 star review:Service techs are great, however, being charged the full $216 service plan before they even show up with a 4 hr window of when they will show when I deliberately stated on the phone I’m going to pay in cash for most of it is ridiculous!! And then stating to them I do not want to be put back on their monthly subscription plan, and then being put on it anyway is a very dishonest way of doing business. This will be the last time I use Dor Mar.

They were able to come to my house the next day and confirmed my water softener was not working and the mineral count in my water was way to high for my comfort for drinking purposes!I ended up purchasing a water softener and RO system from them. They worked with my schedule and came out to install the systems a week later.The 2 men who came out to do the install were very kind and were able to answer any questions I had. They even took out my old softener for me! Thank you Doug, I greatly appreciate you and your co-worker!!
