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

Serving Westerville 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.

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.

Dor Mar always does a great job. Preston was awesome. He helped explain the routine maintenance for our tankless water heaters while he did the work. He also double-checked out radon system as a courtesy.

Great plumbing maintenance service!




Review of Dor-Mar Heating & Air Conditioning

Had a great experience with technician in checking my plumbing system, from the water heater to faucets and sump pump. All checked out great thanks to my water softener and new water heater working as expected. Radon check was a nice included service.

Review of Dor-Mar Heating & Air Conditioning

Brad took time went above and beyond. He took time to show us causes and solutions to our problems. Gave valuable insight and knowledge to our HVAC system. When we mentioned our utility bill had been higher than usual he went above and beyond the main concern (lack of air flow) and found that there was a bad capacitor causing our heat to work overtime. Dispatch also did a great job communicating. Will be staying with Dor Mar for future concerns.
