    I have had My Dear Watson perform several plumbing jobs, including changing out a gas water heater, an air conditioning compressor, and a condensate pump, to name a few. Always courteous, on time, helpful, and reasonable. Nice people too.

    I had an issue with a water leak at my house and couldn't figure out where it was coming from. I called My Dear Watson and they came at 8AM the next morning. They surveyed my systems, diagnosed the issue, and found the problem. They were done within and hour and you wouldn't have even known they were there. Recommend.

Frequently Asked Questions About My Dear Watson Plumbing, Heating & Cooling

What is the difference between oil and gas furnace cleaning?

Oil and gas furnaces require different cleaning approaches. Oil furnaces need specialized attention for the oil burner, which must be cleaned and tuned for optimal performance - a step not necessary for gas furnaces. Both types require maintenance of blower motor compartments, including thorough cleaning and filter replacement to ensure efficient operation and good air quality. The flue pipe and exhaust chambers in both systems need vacuuming to remove debris and prevent dangerous carbon monoxide buildup. For oil furnaces specifically, maintenance includes replacing oil tank and pump screen filters, cleaning the drawer assembly, inspecting electrodes and nozzles, checking oil pressure, and conducting a comprehensive combustion analysis with smoke testing. This thorough maintenance ensures longevity, efficiency, and safety for your heating system throughout the season.

Why do I need to winterize my home?

Winterizing your home during fall is essential to protect your investment. Water damage poses the greatest threat to properties, especially those unoccupied for extended periods. A fundamental preventive measure is shutting off the main water supply when leaving your home for any duration. For homes with hot water heating systems, adding glycol helps safeguard baseboard heaters and heating coils from freezing damage. These winterizing glycols are safe for both plumbing systems and the environment. We recommend developing the habit of shutting down your main water supply even for weekend absences. After closing the main supply, it's important to drain the system to its lowest point, which could be a basement bathroom, utility sink, or the bottom of your water heater.
