Finished a spring maintenance check-up. Cleaned the condenser coils on a Trane XE1200. These outdoor coils collect a lot of dust and pollen, which reduces airflow and efficiency. Regular cleaning is a simple way to improve performance and potentially save on energy costs.

A Burnham Series 2 boiler was experiencing high pressure and frequent relief valve discharge in New Haven. I inspected the expansion tank and found it waterlogged. I replaced it with a Watts ETX-30 diaphragm expansion tank, adjusted system pressure, and bled the radiators. The boiler is now maintaining proper pressure, preventing future overflows and ensuring smooth operation.

Installed a new high-efficiency heating system for a homeowner in New Haven, CT. Their previous unit was outdated and struggling to heat the home effectively. The new system will provide improved energy efficiency and better temperature control. I also optimized the ductwork for more balanced airflow throughout the house.

Brushed and vacuumed flue pipe and heat exchanger Replaced oil filter, nozzle, and strainer Checked all electrical connections and safeties Performed combustion and smoke tests While performing the maintenance we found high levels of sludge at the oil filter. After getting customer authorization we added sludge additive to the oil tank. We also found corrosion starting to form on the inside of the boiler between the sections. Brought the customer down and showed them the corrosion. Recommend replacing the boiler at some point in the future. Upon arrival we found the pressure relief was dripping. Could not see the pressure through the sight glass of the pressure gauge. Removed the plastic and found the boiler was at 30 psi which will cause the pressure relief to drip. Found the autofeed was leaking water by and caused the pressure relief to drip. Drained some pressure from the system and valved off the autofeed. Pressure when leaving was 19
