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 Zanesville’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. Zanesville’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 Zanesville 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 was called to a home in the city to fix a drain line that had been broken. Upon arrival, I found that the drain line had been broken due to something falling and causing it to break. I used a specialized tool to fix the issue and verified that the system was draining properly.

I was called to a home to replace a blower motor and capacitor for a furnace. Upon arrival, I found that the blower motor had failed and was causing the furnace to not blow air. I replaced the blower motor and capacitor and the client was cooling well at the time of service.

I am a home service technician who recently completed a plumbing project for a client. The project involved replacing a broken pipe in the kitchen. I provided an estimate for the project, which included the cost of the materials and labor. I also provided a timeline for the project, which included the date of completion and the start date. The client was pleased with the work and hired me to do additional plumbing work in their home.

This is an estimate to install a new 2 ton ductless mini split. This will include all labor and material to get the system installed and up and running. The systems are in stock and ready for installation. If you would like to have this done, please accept the estimate, and we will get this scheduled. Thank you, Ron.

I am a home service technician, and I recently completed a job for a customer. The customer had photos on file, so I called them to let them know. I then filled out a parts order form for the customer, which they approved. I am currently waiting for the parts to arrive at my shop.
Derrick B.
I was called to a home to check on a unit that was blowing out normal temperature air instead of cold air. Upon arrival, I checked the capacitor, which was still good. I then checked the contactor, which was not shorted out on the backend. I checked the high voltage at the disconnect and found that one leg of 120 volts was missing. I went to the breaker panel and found that one leg of 120 volts had been popped. I flipped the breaker and the unit fired with good temperature split.

I am a highly skilled home service professional who recently completed a plumbing project for a client. The project involved replacing water lines and difficult access in an upstairs bathroom, as well as demoing and replacing all cast in relevance to the stack. The scope of work also included installing new fixtures in the bathroom. I am proud to say that the project was completed on time and within budget, and the client was very satisfied with the results. I am now looking forward to taking on new projects and continuing to provide excellent service to my clients.

I am a home service technician, and I recently completed a job replacing a logic control board. The customer approved the parts, and they will be delivered on Thursday. I installed the new logic board system and it is now up and running. The job is complete.
Adam G.
I am a highly skilled and experienced home service professional. I recently completed a job that involved changing filters, cleaning coils, and checking the operation of a sequence. The first step was to access the air handler unit and remove the access panel. I then removed the old filters and replaced them with new ones. Next, I cleaned the coils using a coil cleaner and a brush. Finally, I checked the operation of the sequence to ensure that it was working properly. Overall, the job was completed quickly and efficiently, and the customer was very satisfied with the results.
