HVAC Repair Northport NY | Call M J Marchia

A noticeable decrease in cooling efficiency, higher-than-normal energy bills, and the unit running longer than usual are key signs of dirty condenser coils. For Northport homes, pollen and debris from our seasons can quickly clog coils. Our technicians perform a thorough inspection and cleaning to restore proper airflow and efficiency.

First, check for simple issues like dead batteries or a tripped circuit breaker. If problems like incorrect temperature readings or the system not turning on/off persist, it's time for expert diagnosis. We repair or replace faulty thermostats to ensure accurate control and comfort, preventing wasted energy.

We recommend bi-annual tune-ups: one for your cooling system in spring and one for heating in fall. This includes cleaning coils, checking refrigerant levels, inspecting electrical components, and calibrating your thermostat. This proactive service helps prevent the common breakdowns we see locally and extends your system's lifespan.
