Heating Contractor
One of our primary services is to serve Westerville’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

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. Westerville’s Top Heating Equipment Supplier

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.

Air Conditioner Installation and Replacement Westerville Ohio
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.

I am a home service technician, and I recently completed a maintenance check on an air conditioning unit. I found that the capacitor needed to be replaced, so I did that and also checked the unit's refrigerant levels. I also cleaned the unit's air filter and checked the unit's electrical connections.

I arrived at the customer's home to perform an AC unit inspection. I ran the unit in AC mode to check for a temperature split. I also checked the amps and ohms of both units, checked the wiring, and checked the pressures on the outside unit. I also performed a radon test.
Calob B.
I was called to a home to check on an air conditioner that was not working. Upon arrival, I found that the unit was running but not cooling the home. I checked the unit and found that the condenser coil was dirty and clogged with debris. I cleaned the coil and the unit started cooling the home again. I also checked the refrigerant levels and found that they were low. I added more refrigerant and the unit started cooling the home again. The homeowner was very happy with the service and thanked me for my help.

I was called to a home to check on a unit that was not working. Upon arrival, I checked the amps and ohms of the unit and found that they were within normal range. I also checked the wiring and found that it was in good condition. I then checked the pressures on the condenser and found that they were within normal range. Finally, I sprayed off the coil and found that it was clean.

I arrived at the customer's home to find that their air conditioner was not working properly. Upon inspection, I discovered that the unit was low on refrigerant and had a 17-degree split. I added more refrigerant to the system and checked the temperature split again. The unit was now running smoothly and efficiently. The customer was very pleased with the service and thanked me for my help.

I am a highly skilled and experienced home service professional. I recently completed a job that involved performing air conditioning maintenance on a residential property. The maintenance checklists were extensive, and I had to ensure that all the necessary tasks were completed to the highest standard. The first step was to inspect the air conditioning unit and identify any potential issues. I checked the refrigerant levels, cleaned the coils, and replaced any damaged parts. I also tested the electrical components to ensure they were working properly. Next, I cleaned the air filters and replaced them if they were dirty. This is important because dirty filters can reduce the efficiency of the air conditioning unit and increase energy consumption. I also checked the ductwork for any leaks or damage. Finally, I performed a test run of the air conditioning unit to ensure it was working properly. I checked the temperature settings, the airflow, and the humidity levels. I also made any ne

Ron M.
I am a skilled professional that works for a Dor-Mar Heating & Air Conditioning company. I recently completed a job at a residential home in the city. The job involved cleaning the coils, changing the filters, and replacing the belts. The units were working correctly after the job was completed.
Trevon S.
I was dispatched to a residential home for a unit that was not cooling. Upon arrival, I found that the compressor was not running. I checked the capacitor and found that it was not working. I replaced the capacitor with one on the truck and the unit started up. I then hooked up the gauges to read the refrigerant pressures and found that the system was low on refrigerant. I added 2 pounds of 410a to the system and the unit is now up and running.
Khyrenn F.
I was called to a home to repair a faulty air conditioner. Upon arrival, I found that the capacitor had failed, causing the system to malfunction. I replaced the capacitor and tested the system to ensure it was working properly. I also checked the refrigerant levels and added more if necessary. Finally, I cleaned the condenser coils and checked the electrical connections to ensure they were secure. The customer was very satisfied with the work and thanked me for my prompt and efficient service.
