Metro-Boston Air & Refrigeration: Qualified HVAC Repair Serving Melrose, MA 02176

Common signs include a yellow or flickering furnace flame (it should be blue), soot or staining around your appliance, excessive condensation on windows, and flu-like symptoms in household members that improve when you leave home. If you suspect an issue, leave immediately and call 911, then contact us for a professional inspection. We perform comprehensive safety checks on furnaces and boilers to identify and resolve carbon monoxide risks.

Often, thermostat malfunctions are repairable or simply require an update. Our technicians will first diagnose whether it's a wiring issue, dead batteries, a faulty thermostat, or a signal problem with your furnace or AC. We'll explain your options, from repairing your current unit to installing a modern, programmable, or smart thermostat that can improve your home's efficiency and comfort in our New England climate.

We recommend an annual professional tune-up, ideally in the fall before the heating season. This service includes cleaning critical components, checking for carbon monoxide leaks, testing safety controls, and ensuring efficient operation. Regular maintenance is the best way to prevent unexpected breakdowns during cold snaps, improve your system's lifespan, and most importantly, keep your family safe from potential hazards.
