Efficiency Testing
DEP‑required combustion efficiency testing to keep your boiler safe, compliant, and optimized — on every fuel and at every firing rate.
NYC DEP Compliance
We perform all required combustion efficiency testing per NYC Department of Environmental Protection guidelines.
What Our Efficiency Testing Includes
We perform all necessary combustion efficiency testing as required by the New York City Department of Environmental Protection (DEP). After your boiler is cleaned and the burner is overhauled, it is essential to test efficiency on both gas and oil for dual-fuel burners, and at both high and low fire. Our professional technicians ensure your heating equipment is tuned to run at optimal levels on all fuels.
DEP-required combustion efficiency testing
Post-cleaning & post-overhaul validation
Dual-fuel (gas & oil) testing
High-fire and low-fire tuning
Optimization for safety & fuel savings
Before
Heavy soot build-up reduces heat transfer and efficiency.
After
Clean tubes restore proper airflow and peak efficiency.
