HVAC Contractor

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.

Brian was our tech today. I had the best experience while he tested our heating system. He explained everything he was doing so that even I could understand. He gave all possible options so that we could choose which best suited us and our needs. He wasn’t pushy and didn’t try to up-sell us something we didn’t need or want. We will definitely come to this company for all of our HVAC needs and will request Brian if he’s available.

Dor-Mar was great called in the AM and they were able to come out that day. Brian the technician that came out was very professional and friendly. He was able to identify and confirm the problem. He promptly resolved my issue and our air was back to normal!
Kyle B.
Recently had an air conditioner go belly up on 4 of the hottest days starting on Memorial Day. We called Dor-Mar the night before and a technician Wes arrived first thing on Memorial Day. Wes did all he could then delivered the bad news, but fortunately he was very knowledgeable with helping us choose a new system. We were so pleased that we decided to add on a new furnace as well at the same time. Dor-Mar also was kind enough to deliver a portable air conditioner to us to get us by for the 3 days for install. Doug and Tyler arrived on Thursday and I was very impressed with them. Not only were they kind and considerate Doug was so knowledgeable on the equipment he answered every question we had and left us feeling very confident with our install with new Rheem equipment. Very happy customer.
