Derrick is exceptional!

Derrick was absolutely a pleasure to work with. He treated me like I was a member of his family. It was clear that he was not just concerned about getting the account; he was concerned about my health. Specifically, I have a significantly amount of black mold, which could do great harm. Thank you, Derrick! You are a class act!

I am a highly skilled home service professional who has successfully completed furnace maintenance for a client. During the maintenance process, I verified the operational performance of the system, ensuring that all components functioned as intended. The carbon buildup on the flame sensor was thoroughly cleaned to enhance efficiency. Additionally, I assessed the amp draw of both the blower and inducer motor to confirm they were operating within acceptable parameters. I also replaced the air filter and inspected the electrical connections for any signs of damage. Finally, I provided the client with a detailed report outlining the maintenance performed and any recommendations for future maintenance.

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 customer had been experiencing issues with their heating and air conditioning system, and they were concerned that it might need to be replaced. I arrived at the home and performed a thorough inspection of the system. I checked the thermostat, the air filters, the ducts, and the furnace. I also checked the electrical connections and the gas lines. After the inspection, I determined that the system was running great. I explained to the customer the steps that I had taken to diagnose the problem and the steps that I would take to fix it. I also provided them with a quote for the repairs. The customer was pleased with the results and decided to have the repairs completed. I scheduled the repairs for the next day and arrived on time. I worked diligently to complete the repairs and ensure that the system was running properly. After th

I am a highly skilled home service professional. I received a call for a leaking water sea mode call. Upon arrival, I found that the evaporator coil drain had become clogged with excessive rust and mold. I cleared the drain and inspected the system for safety. I discovered that the system had a cracked heat exchanger. I discussed different options with the client, and they decided to shop around for quotes before making a decision. I will let them know which company they decide to go with.

The toilet was not flushing properly. I checked the tank and found that the water level was low. I flushed the toilet and the water level rose. I checked the pipes and found that there was a blockage. I used a plunger to clear the blockage and the toilet started flushing properly. I also checked the pipes for any leaks and found none.
