Milford, NH Homeowner Learns How Critical This Is
A blocked outside vent to your heating system, caused by snow, ice or some other debris, can cause the entire system to shut down. If the HVAC unit does not have an automatic shut-off, the excessive heat caused by the blockage can cause significant damage. Even worse, carbon monoxide and other toxic chemicals can leak into the home, putting everyone living there at serious risk.
A homeowner in Milford recently contacted Joyce Cooling & Heating Inc.. His heating system was no longer working. A technician was able to troubleshoot the problem immediately.
Snowfall Accumulations Can Block Outdoor Vents
As snow drifts accumulate throughout the winter storms, the snow drifts can block your outdoor vents. Without being able to release the hot air outside, the HVAC system can overheat. It is important to know where your outside vents are located and to ensure that this area is cleared so that the unit is properly vented. Even a partial blockage can affect the unit’s ability to heat the home and affect the energy efficiency. The snow should be cleared away by hand or with a soft brush. Using a shovel or snowblower can cause damage to the furnace vent pipe.
Snow building up outside the vent can also cause ice and frost to accumulate. This can further block the HVAC system’s ability to work properly, as it inhibits air flow. If there is ice around the vent, gently scrape this off with your hand or you can use a plastic putty knife. Inspecting for ice is especially important during very cold temperatures.
The cause for the heating shut-off in Milford was a safety feature in the HVAC system triggered by an abundance of carbon monoxide. A Joyce Cooling & Heating Inc. technician was able to clear the vent and get the unit once again running properly.
