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.

dye test/ Inventory dye and cartridge AND INSTALL UV LIGHT. COIL CLEANING. COLLECT PAYMENT WHEN COMPLETE. ANY QUESTIONS CONTACT DAVE.
Brandon M.
Performed a/maintenance. Return air filters were both clean. Found evaporator coil for the main floor system had lots of rust and corrosion, as well as quite a bit of debris build up on the coil and potentially mild build up on the coil as well. Checked pressures and found pressures on the older system to be slightly low. Pressures on the new system were good. Amp draws were both good. I would recommend having evaporator coil cleaned and possibly refrigerant added to allow system to cool properly.

NEED TO RETURN TO REPLACE THE CONTROL BOARD FOR FURNACE. CONTROL BOARD IS UNDER WARRANTY. COLLECT PAYMENT FOR LABOR WHEN COMPLETE.
Courtland K.
Inducer motor amp draw is high. Likely crack in heat exchanger, bearings completely out in the inducer motor. Blower motor bearings likely out too. Blower wheel is rusted. Due to the age and condition of the furnace I would recommend replacing rather than repairing.
Willie N.
NEED TO RETURN TO REPLACE THERMOSTAT WIRE FOR FURNACE. COLLECT PAYMENT WHEN complete. Tried to run new thermostat wire was unsuccessful. I would have to cut into customers. Unfinished basement ceiling to do the work and he declined, but I did charge an hour labor for trying.
