Heating and hot water

Older homes may combine steam radiators, hot water zones, multiple thermostats, humidifiers and gas fireplaces. We inspect and test before deciding what needs service, and we check the heating system before the cold. Our technicians have experience with Lochinvar boilers and water heaters.
On an agreement, boiler service, humidifier settings, fireplace changeovers, chimney checks and boiler filings follow the house checklist. NYC Brownstone General Contracting diagnoses failures and handles repairs, controls, water heaters and related system work.

Questions
Do you work on pre-war systems and steam heat?
Yes. Older New York City homes, including their piping, controls and restricted equipment spaces, are familiar ground. We inspect the existing system before deciding what should be maintained or recommending a repair or improvement.
Why is my boiler short-cycling?
Short-cycling means the boiler turns on and off more often than it should. Possible causes include thermostat or control problems, restricted airflow, pressure problems, dirty components or equipment that is not operating correctly. The system needs to be diagnosed before a repair or replacement is recommended.
Why is one floor colder than the others?
Uneven temperatures can come from airflow or balancing problems, thermostats or controls, insulation, water pressure, radiators, piping or ductwork. We inspect and test the system before recommending the next step.
How do you decide whether to repair or replace equipment?
The recommendation is based on what is most cost-effective for the owner. We consider the equipment's age and condition, how long a repair is likely to last, parts availability, efficiency and the risk of another failure. We explain the options before you decide.
How do I schedule heating service before winter?
Call the office early to schedule a heating inspection and service before cold weather. Agreement clients have this seasonal work scheduled through their property manager as part of the house's maintenance plan.

We walk through the house with you and look at its condition and its systems. The office then writes the checklist and the agreement, priced from what the walkthrough found.
