Installed a new Viessmann boiler and corrected the exterior venting to improve system reliability, efficiency, and safe operation. Connected to existing heating and electrical systems. Purged boiler free of air. Performed 3 minute gas leak check at 8 inches of water column. Performed combustion test of boiler and confirmed proper operation of boiler. Installed a Rinnai on-demand propane water heater flowed water through existing indirect tank to ensure tank stays flushed. Installed bypass valves to make on demand water heater the prime source for hot water.

Arrived on site to perform an annual tune up on propane furnace and to inspect some vents not blowing hot air. After our inspection, we found that the ductwork under the house was in really bad shape. We could not access most of the ducting as plumbing pipes were in the way and the crawlspace is about 2 feet tall. The ducting in general was pretty poor. They said they may be tearing up the subfloor soon and when they do we can come back to inspect the ductwork more to see what can be done. We will performed the tune up on the propane furnace. The tune up included inspecting the flame sensor, igniter, burners, heat exchanger, and general electrical components. We got approval to replace the igniter after we tested it and it came to about 125ohms. We look for around 50-60 for hot surface igniters. We wire brushed the burners and inspected heat exchanger tubes. Everything looked okay for the age. We then performed a combustion analysis and checked for CO leaks. Analysis was good and no

We were called to evaluate a shower leak and low water pressure concern. Upon inspection, we observed signs of active or prior leaking on the sheetrock ceiling below the bathroom, with likely failure of sealant around the shower drain, valve escutcheon, and shower arm penetrations contributing to the issue. We also noted lower than desired water pressure at the shower fixture. At the homeowner’s request, we applied new sealant to the shower drain, valve escutcheon, and shower arm areas as an attempt to correct the leak without opening the sheetrock ceiling below. We also adjusted the home’s pressure reducing valve to improve overall water pressure and installed a new chrome Kohler shower head to enhance performance and reliability. The shower was not tested after completion in order to allow proper curing of the newly applied sealant. The homeowner was advised to wait a minimum of 24 hours before using the shower to allow the sealant to fully cure and dry. The homeowner was advised t

Returned from the previous visit to complete the installation of a new boiler feed valve. The new valve was properly installed and adjusted to ensure the boiler maintains the correct water pressure for safe and efficient operation. After installation, the system was tested and confirmed to be functioning properly at the time of service.

Performed annual preventive maintenance on the oil-fired boiler system. Service included a comprehensive inspection of all safety controls and operating components to verify safe operation, optimal efficiency, and compliance with manufacturer specifications. Replaced the oil nozzle and oil filter, cleaned the fuel strainer, and thoroughly brushed and vacuumed the boiler heat exchanger and smoke pipe to remove soot and debris buildup. Conducted a combustion analysis and draft test to confirm proper burner performance and ventilation. All readings were within acceptable ranges, and the boiler is operating properly at this time. Reviewed system safety controls and general operating guidelines with the customer.

Upon inspection, the existing water heater was due for replacement and the boiler’s automatic water feeder was found to be malfunctioning. We removed the old water heater and professionally installed the homeowner-supplied unit, added a new thermal expansion tank to protect the plumbing system from excess pressure, and replaced the defective boiler water feeder to ensure proper and automatic system water replenishment. All water connections were completed in accordance with current plumbing and mechanical code standards, the system was filled and tested for proper operation, and all components were verified for safe, leak-free performance. The system is now operating reliably, providing safe hot water and improved protection for the home’s plumbing and heating systems.

Service Report Customer reported water leaking in the boiler room from two separate heating zones. Upon inspection, I found multiple high air vents that were heavily corroded and determined them to be the source of the leaks. Three high vents were replaced due to corrosion and failure. After replacement, I purged the affected zones to remove air from the system and verified proper circulation. All zones were confirmed to be heating properly, returning hot water, and no leaks were present at the time of departure. The system is currently operating as designed. Customer also reported ongoing issues with their well system. They stated they will be contacting the company that currently services their well for further evaluation. Additionally, we recommend having one of our plumbers inspect the piping to the well tank, as well as the well tank itself, to ensure there are no related issues contributing to system concerns. Customer requested estimates for the following additional work:

This project included the complete removal and replacement of the existing outdated boiler and domestic water heater with new equipment. All near-boiler piping and wiring were upgraded to ensure safe, reliable, and code-compliant operation. The supply and return manifolds were replaced to improve system performance and overall heat distribution. A scale prevention device and thermostatic mixing valve were installed on the new water heater to enhance longevity and provide consistent water temperature control. The water heater tank temperature was set to 140°F, and the mixing valve was calibrated to 4.5, delivering 120°F water to all fixtures for optimal safety and comfort. All heating zones were thoroughly purged to remove trapped air, ensuring proper circulation and balanced heat distribution throughout the system. System flow and operation were verified to confirm each zone is functioning as designed. A boiler treatment inhibitor was added to the system to help prevent corrosion and

The homeowners contacted our company to replace the internal components of the toilet shut-off valve after discovering it was no longer sealing properly. The issue was identified when the toilet began running continuously while the homeowners were away and did not shut off, resulting in the toilet overflowing and causing significant water damage to the bathroom flooring, surrounding walls, paint, and the ceiling below. During evaluation, it was also found that the PVC toilet drain line had broken as a result of the incident and subsequent stress to the system. On 2/13/2026, we repaired the toilet shut-off valve by replacing the failed internal components to restore proper water control and prevent further leakage. The remaining repairs—including replacement of the damaged PVC drain piping and removal and replacement of the faulty toilet (identified as the root cause of the overflow event)—are scheduled to be completed at a later date.

Performed annual preventive maintenance on the oil-fired boiler system, including a comprehensive inspection and testing of all safety controls, combustion components, and operating systems to verify safe and efficient operation in accordance with manufacturer specifications. Replaced the oil nozzle, oil filter, and pump strainer. Oil line was plugged with sludge, we used a push pull pump to remove sludge. Conducted a combustion analysis and draft test to confirm proper burner performance and venting. Rebuilt the air scoop assembly to restore proper air elimination and ensure the hydronic system is free of trapped air for optimal operation. At the customer’s request, we will return in the spring to evaluate the attic air handler system.
