Zone Heating & Air Conditioning Inc. | Qualified HVAC Repair in Rocky Point, NY

Common signs include unusual banging or kettling noises from the boiler, frequent pressure gauge readings that are too high or too low (outside the 1-2 bar range), and your system constantly needing to be repressurized. These issues can strain your entire HVAC system. Our technicians can diagnose the root cause—often a faulty pressure relief valve or expansion vessel—and perform the necessary repair to restore safe, efficient operation.

Modern, high-efficiency HVAC systems are engineered with advanced safety features and superior combustion technology, drastically reducing the risk of carbon monoxide (CO) production. When we install a new furnace or boiler in your home, we ensure it's perfectly sized for your house and properly vented. This correct installation is critical for safety. We also strongly recommend pairing any new installation with CO detectors on every level of your home for complete peace of mind.

It can be. A dusty smell when first turning on the heat is often normal, but a persistent burning smell, or a sharp, chemical odor could indicate an electrical issue or overheating component. Most critically, a smell like formaldehyde or exhaust fumes could signal a crack in the heat exchanger, which is a potential source of carbon monoxide. If you notice unusual smells, especially alongside symptoms like soot around the appliance or pilot lights that frequently blow out, shut off the system and call us immediately for a safety inspection and repair.
