Trusted HVAC Repair in Brooklyn, NY 11211 - Marc Air Conditioning & Refrigeration

In Brooklyn homes, short cycling is often caused by a clogged air filter restricting airflow, an oversized unit for the space, or a faulty flame sensor. Our first step is a thorough diagnosis to pinpoint the exact issue. We'll clean or replace filters, test components, and calibrate your system for efficient, long-running cycles that properly heat your home and reduce wear and tear.

We frequently respond to boiler failures due to issues like a broken circulator pump, a failed ignition system, or low water pressure—common problems in Brooklyn's aging systems. Our technicians are experts in all major boiler brands. We carry many common parts on our trucks to facilitate same-day repairs, getting your heat and hot water restored as quickly as possible.

We recommend a pre-season tune-up, ideally in the fall. This includes cleaning critical components like the heat exchanger and burners, checking for gas leaks or carbon monoxide issues, testing safety controls, and verifying system pressure and airflow. This proactive service catches small problems before they become full breakdowns, ensuring your system runs safely and efficiently all season long.
