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

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.

I was contacted by a client who needed a maintenance visit for their home's air conditioning unit. The client informed me that the blower unit was making noise and that they had already spoken to a representative from the company. I asked the client to provide me with the necessary information to schedule the maintenance visit, including the model number of the unit and the date and time of the visit. I also asked the client to provide me with any specific concerns or issues they were experiencing with the unit. After receiving the necessary information, I scheduled the maintenance visit for the following day. I arrived at the client's home and performed a thorough inspection of the air conditioning unit. I identified the issue as a loose blower unit and replaced the belt and filters. I also cleaned the condenser and evaporator coils to ensure proper airflow. After completing the maintenance visit, I provided the client with a detailed invoice and explained the services that were per

I am a skilled professional that works for a Dor-Mar Heating & Air Conditioning company. I recently completed a job for a customer who was concerned about the quality of their indoor air. They had noticed a musty smell in their home and wanted to have their air ducts cleaned. I started by performing a WH flush on the air ducts to remove any debris or contaminants that could be causing the smell. The WH flush is a process that involves using high-pressure water to clean the ducts from the inside out. After the WH flush, I performed a radon test to determine the level of radon in the air ducts. Radon is a naturally occurring gas that can be harmful to human health if it is present in high levels. The radon test involved placing a radon detector in the air ducts for a period of time. The detector measured the level of radon in the air and provided a reading. Based on the results of the WH flush and radon test, I recommended that the customer have their air ducts cleaned and sealed. Thi
