B & S Heating-Air Conditioning and Refrigeration | Experienced HVAC Repair in Waltham, MA

First, check that your thermostat is set to "heat" and that the circuit breaker hasn't tripped. If those are fine and you have no heat, it's best to call a professional like B & S Heating. Attempting repairs yourself on a gas boiler can be dangerous and may void warranties. Our local technicians can quickly diagnose common Waltham boiler issues like faulty ignitors, low water pressure, or circulator pump failures to get your heat back on safely.

Warning signs include a yellow or flickering burner flame (it should be blue and steady), soot or rust on your furnace or boiler, and excessive moisture on windows near the unit. The most important step is to install working CO detectors on every floor of your Waltham home and have your heating system inspected annually by a certified technician. B & S Heating performs comprehensive safety checks to ensure proper ventilation and combustion, protecting your family from this silent hazard.

Our preventative maintenance visit is designed for our local climate and common systems. We thoroughly clean and inspect critical components like the heat exchanger for cracks, test for carbon monoxide, check gas pressure and electrical connections, lubricate moving parts, and ensure your system vents properly. This proactive service not only improves safety and efficiency but also helps prevent unexpected breakdowns during our coldest months, saving you money on energy bills and costly emergency repairs.
