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.

"In the past two years, we have trusted Dor Mar Heating & Air Conditioning to diagnose, perform maintenance to and ultimately replace both our furnace and central air conditioning systems. Our every contact with Dor Mar folks, from the tech team on-site to the management and office support teams, has been superior to any other related company we have interacted with. Their work was precision, covering all the details to make certain their systems used to replace our original systems were installed perfectly. At every turn, I have been very impressed with the Dor Mar technicians and back office/management folks and would highly recommend Dor Mar for any AC/Heating system maintenance and/or system replacement you may need."

Today, we have performed necessary routine maintenance on your air conditioning unit. Our technician diligently conducted an examination of both the indoor and outdoor coils to ensure their satisfactory condition. Furthermore, we carefully inspected all electrical connections for any signs of damage and assessed the amp readings of the blower motor, condenser fan, and compressor. Thorough examinations were also conducted on the refrigerant pressures, as well as the contactor and capacitor readings.
