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 Pataskala’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. Pataskala’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.
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 Pataskala 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.

Preston R.
I was called to a home to repair a drain that was not draining properly. I arrived at the house and inspected the drain. I found that the drain was clogged with debris and needed to be cleaned out. I used a drain snake to clear the drain and then used a hydro jet to clean out the drain completely. After the drain was cleared, I tested it to make sure it was draining properly. The customer was very happy with the work and paid me for the job.

*I was dispatched to a home for a possible cartridge replacement. * The client was taking a shower, making it difficult to identify the issue. * Upon arrival, I noticed water dripping from the shower. * I removed the handle and found that the cartridge was leaking. * I replaced the cartridge and the client was satisfied with the service. * No other issues were found in the home.

I was called to a home to replace a thermostat and fix a blown furnace fuse. Upon arrival, I discovered that the thermostat was set for rh only, causing the furnace to not turn on. I corrected the issue by resetting the thermostat and adjusting the furnace fuse. After testing the system, I found that the heating and cooling worked great.

Trevon S.
I am a highly skilled and experienced home service professional. During the recent maintenance visit, I conducted a thorough evaluation of the air conditioning system. I initiated the session by inquiring about any specific concerns the customer might have had. I assessed the condition of the furnace filter and evaporator coil, recorded the blower amp draw, inspected the cleanliness of the condenser coil outside, examined the electrical components of the condenser for any signs of burnt or loose wires, and verified the microfarad readings on the capacitor. Finally, I confirmed that the refrigerant pressures were within the correct range to guarantee optimal system performance.

Preston R.
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 checklist included tasks such as checking the refrigerant levels, cleaning the air filters, and inspecting the condenser coils. I also replaced a POF 10mf blower capacitor that was out of stock in the truck. The job required careful attention to detail and a thorough understanding of the HVAC system. I am proud to have completed the job successfully and to have provided my clients with the high-quality service they deserve.

Calob B.
I am a highly skilled home service professional. I recently completed a job where I installed an air conditioner in a residential home. The job went smoothly, and the customer was very satisfied with the results. The air conditioner is now running good, and the customer is ready for the summer.

Preston R.
I recently completed a job for a home service company. The job involved estimating the cost of labor, half a pound of refrigerant, and sealant. I started by inspecting the unit and taking measurements to determine the size and scope of the job. I then provided a detailed estimate of the cost of the labor, refrigerant, and sealant, including any additional materials or tools that may be required. I also explained the process of the job and the expected timeline for completion. The client was pleased with the estimate and hired me to perform the job.
Travis V.
I was hired to install a hot water tank and expansion tank in a residential home. The hot water tank was located in the basement, and the expansion tank was located in the attic. I began by disconnecting the power and water supply lines to the old hot water tank and expansion tank. I then removed the old tank and expansion tank and disposed of them properly. I installed the new hot water tank and expansion tank in their respective locations and connected the power and water supply lines. I also tested the tank and expansion tank to ensure they were working properly.

Zach S.
I am a skilled professional that works for a Dor-Mar Heating & Air Conditioning company. I received a call from a customer who was experiencing issues with their heating and air conditioning system. Upon arrival, I discovered that the timer was stripped and needed to be replaced. I also noticed that the knob on the thermostat was broken. I replaced the timer and knob with new ones and tested the system to ensure it was working properly. The customer was very satisfied with the work I performed and thanked me for my help.
