Great tech, great work

Great work! Had a super old furnace that broke, of course during the coldest weather. Ben was able to remove it and install the new one in no time. Kept me in the loop about everything, and house went from 40 degrees to 65 super quickly! So grateful he was so knowledgeable and efficient. Couldn’t have asked for a better tech!

I had a great experience with Derrick from Dor-Mar Heating and Cooling. He was honest, professional, and did an excellent job getting my furnace back up and running. Derrick was very informative, took the time to explain what was going on, and was not pushy at all, which I really appreciated. It’s refreshing to work with a technician who’s knowledgeable and straightforward. Highly recommend Derrick and Dor-Mar Heating and Cooling!

Today, I addressed an issue with a tankless water heater installed about two years ago. The client reported an error code 12, indicating an exhaust/gas problem. Upon inspection, I noticed a large icicle obstructing the vent. Using a heat gun, I carefully melted the icicle to restore proper ventilation. After ensuring the vent was clear, I conducted multiple tests by running various faucets. The error code did not reappear, confirming the issue was resolved. The water heater is now functioning correctly.

Upon inspection, the system was correctly configured for an inverter-driven compressor. However, the electric heat was not switching over automatically. I adjusted the thermostat settings to enable dual fuel capability, ensuring the system would switch to emergency heat when needed. Specifically, I set the changeover temperature to 20°F. This adjustment guarantees that the system will operate in emergency heat mode whenever the outside temperature drops below 20°F, optimizing energy efficiency and performance during colder weather. The system is now fully functional, providing reliable heating even in extreme conditions.

Upon arrival, I found the system operational, despite the customer having previously shut it down due to a whistling sound. A thorough inspection of the heat pack and blower motor revealed no issues. However, the filter rack was undersized for the equipment, and the customer had been using a MERV 12 filter. This likely caused the system to starve for air, leading to the whistling sound. I replaced the MERV 12 filter with a MERV 8 filter, which is more suitable for the equipment. No other issues were found, and the system is now functioning properly.

The furnace maintenance was successfully completed, ensuring optimal performance. We meticulously cleaned the carbon buildup on the flame sensor, enhancing the system's efficiency. Both the blower and inducer motor were assessed for amp draw, confirming they operate within acceptable parameters. During the inspection, high radon levels were detected. We discussed potential mitigation options, and the customer expressed interest in a system that could be installed in a location other than outside the house. Our team is prepared to explore and implement suitable solutions to address this concern.
