Found bad motor

I called Dormar told them our blower motor quit working and it was either the motor or a control relay. He confirmed it was the motor and wrote up a estimate.

Dor Mar makes it easy

Dor Mar keeps my HVAC appliances in working order all year, every year. I work 3 jobs and don’t have a lot of extra time to deal with these types of things. They always give me courtesy calls to remind me when it’s time to check things each season. Makes one less thing to worry about in this fast-paced life.

I was a professional who worked for a Dor-Mar Heating & Air Conditioning company. I was responsible for installing insulation and reconnecting heat runs. I started by removing the old insulation and cleaning the area. I then installed the new insulation and secured it in place. I reconnected the heat runs and tested the system to ensure it was working properly. I also cleaned up the work area and disposed of the old insulation properly.

I was called to a home to install a new thermostat and test the heating and air conditioning system. Upon arrival, I found that the thermostat was not wired correctly, so I had to rewire it. After that, I tested the system and found no issues.

I am a highly skilled and experienced home service professional. I recently completed a job replacing a blower motor and squirrel cage system for a furnace. The old motor was noisy and not working properly, so I replaced it with a new one that is quieter and more efficient. I also replaced the squirrel cage system, which is the part of the furnace that moves the air through the vents. The new system is up and working great, and the customer is very happy with the results.

I was called to follow up on a job that was completed a few days prior. The client had called to complain that their air conditioner wasn’t cooling properly. I arrived at the client’s home and found that the coil was not in stock. I filled the system with 1 pound of 410a refrigerant and got the pressures and temperature splits correct. I awaited the arrival of the evaporator coil to be swapped out.

I was dispatched to a home in the city to check on a heating and air conditioning unit that was not working. Upon arrival, I found that the power was out to the unit and the electric panel inside was locked. I needed to restore power to the unit to check the hvac meter. I was unable to gain access to the electric panel because the key was not available. I had to call the power company to restore power to the unit.

I was called to a customer's home to fix a leaking supply line. I provided a verbal estimate for the job, which the customer agreed to. I then went to work repairing the leak, which took about an hour. The customer was very satisfied with the work I did and paid me in full.
