Service Master Heating & Air Conditioning Corp - Merrick's Certified HVAC Repair

Common signs in Merrick homes include uneven heating or cooling between rooms, higher-than-normal energy bills, and excessive dust. You might also hear whistling sounds from the ducts. Our technicians perform a professional pressure test to accurately locate and measure leaks, then seal them with durable mastics or metal-backed tape to restore your system's efficiency and comfort.

First, check simple things like the thermostat settings, circuit breaker, and that the system has power and water pressure. If it's still not working, don't delay—especially during our colder months. A sudden boiler failure in Merrick often indicates a faulty component like a circulator pump, ignition control, or pressure valve. Call us for a prompt diagnosis and repair to restore your heat safely and prevent further damage.

Our comprehensive tune-up includes cleaning critical components like the burner assembly and heat exchanger, checking for carbon monoxide leaks, testing safety controls, lubricating moving parts, and inspecting the entire system for wear. For boilers, we also verify water pressure and inspect the expansion tank. This proactive service helps prevent the breakdowns and inefficiencies common in our area, ensuring your system runs reliably and efficiently.
