I was recommended Dor Mar by a neighbor a few years ago and will continue to use them. Ron was a pleasure to work with. He’s very knowledgeable and helped me understand what was going on with my furnace that I had no clue about. Thanks!

Derrick showed up, ran some diagnostic checks on the furnace, and determined the root cause of the issue in less than an hour. Our furnace is going to need another visit, but he got our heat up and running until a permanent fix can be implemented.

Upon inspection, it was determined that the boiler's aquastat and gas valve required replacement. I promptly returned to address these issues. The aquastat, responsible for regulating the water temperature, was replaced to ensure efficient boiler operation. Additionally, the gas valve, which controls the flow of gas to the burner, was replaced to maintain safe and reliable performance. Furthermore, the thermal fuse had blown, indicating an unsafe flame rollout system. This critical component was replaced to prevent any potential hazards and ensure the boiler operates safely.

Upon inspection, it was determined that the system required a new gas valve to ensure proper functionality and safety. I communicated the issue to Sean and explained the necessity of the replacement. Sean approved the work and we agreed that the replacement would be carried out in the morning. I ensured all necessary steps were documented in pinned notes for future reference and to maintain a clear record of the work performed. The new gas valve was installed successfully, and the system is now operating as intended.
Upon inspection, the practice unit was not heating. I verified both high and low voltage supplies to the circuit board, confirming they were within acceptable ranges. Despite the correct voltages, the unit remained unresponsive. Further investigation revealed a faulty circuit board. To prevent additional damage, I unplugged the unit. I placed an order for a new circuit board and ensured the unit was safely disconnected until the replacement arrives.
Upon arrival, I first inspected the unit for heating issues and an airflow fault. I began by examining the air filter for clogs and cleaned it if necessary. Next, I checked the evaporator coil for dirt and debris, ensuring it was free from obstructions. I adjusted the fan speed from medium low to medium high to enhance airflow. I also opened a register in the basement to facilitate better air circulation. Additionally, I measured the gas pressure, which was slightly high, and adjusted it accordingly. Finally, I conducted a check for CO2 leaks in the supply air. The system is now functioning correctly.

I began by ensuring the thermostat was set to the cooling mode. I then disabled the scheduling feature to allow for manual control of the system. Next, I meticulously cleaned the flame sensor to ensure optimal performance and safety. Following this, I conducted a carbon monoxide test to verify the system's efficiency and safety. I also cleared the outdoor termination to remove any obstructions that could impede airflow. Throughout the process, I maintained a focus on precision and safety, ensuring that all components were functioning correctly. The system is now ready for use, providing a comfortable environment.
We began by gathering all necessary pricing information from our distributor to ensure accurate cost estimates for the project. This step was crucial to avoid any discrepancies in the final bill. After receiving the comprehensive pricing details, we proceeded to create an over-estimate, which provided a detailed breakdown of all potential costs involved. This over-estimate served as a transparent and thorough guide for our client, ensuring they were fully informed about the financial aspects of the project. The meticulous approach allowed us to maintain high standards of accuracy and customer satisfaction.
Upon arrival, I conducted a thorough inspection of the heating system. I tested the functionality of the unit, ensuring it was operating efficiently. After identifying a minor issue, I promptly made the necessary adjustments. I also reviewed the system's settings to optimize performance. Following the repair, I conducted a series of tests to confirm the system was working correctly. The store manager confirmed the heat was functioning properly, expressing satisfaction with the service.

During the furnace service, I identified that the air filter was excessively dirty, which was impeding system performance. Additionally, the flame sensor was coated with grime, affecting its efficiency. I meticulously cleaned the flame sensor, restoring its functionality. I advised the client to replace the air filter to ensure optimal system operation. After these adjustments, the furnace functioned correctly. Given the system's age, I recommended a comprehensive visual inspection of the heat exchanger during our next scheduled maintenance to preemptively address any potential issues with integral components.
