During the furnace inspection, I identified a failed igniter in the system. While one igniter was functioning correctly, it was crucial to conduct a thorough combustion analysis to rule out any additional issues with the unit. The analysis is necessary to ensure optimal performance and safety. Additionally, I observed rust in the combustion chamber, which could potentially affect the system's efficiency and longevity. I recommended cleaning and treating the rust to prevent further deterioration. Scheduling a follow-up visit to complete the combustion analysis and address the rust issue is essential for maintaining the furnace's proper functioning.

I was called to a home to fix a heating issue. The unit was not wired for aux heat, so I wired in the heat strips and tested the heating. I found that the heat strips were not working, so I replaced them. After replacing the heat strips, I tested the heating again, and it was working properly.

I completed a furnace inspection today, checking the air filter and recommending a change out as soon as possible. I also checked the resistance across the ignition system, which came back good. I noticed some carbon buildup on the flame rod, so I cleaned it off to ensure efficient operation. I verified the good operation of the gas valve and adequate heat being added to the air. There were no concerns with the system's operation.

I am a highly skilled and experienced home service professional. I recently completed a job that involved changing filters and checking the operation of a sequence. The sequence was a complex system that controlled the flow of water in a residential building. The first step in the job was to access the system and remove the old filters. I then replaced the filters with new ones and tested the system to ensure that it was operating correctly. Next, I checked the pressure and flow rates of the system to ensure that they were within the manufacturer's specifications. If any issues were found, I made the necessary adjustments to the system to ensure that it was operating properly. Finally, I cleaned up the area and disposed of the old filters properly. This job required a lot of skill and attention to detail, and I was pleased to be able to complete it successfully.

I was hired to repair a metal fence. The fence was made of metal and had some rust on it. I used a wire brush to remove the rust and then applied a coat of primer to the fence. After the primer dried, I applied a coat of paint to the fence. The fence looks great now.

I was tasked with installing a new outside condenser for a customer. The condenser was a large unit that needed to be installed on the roof of the customer's home. I had to remove the old unit and install the new one in its place. This involved disconnecting the electrical wiring, gas lines, and refrigerant lines. I also had to make sure that the new unit was level and securely fastened to the roof. Once the new unit was installed, I had to test it to make sure it was working properly. I also cleaned up the area and removed all of the old equipment.
