Kill your heating system one month at a time

How great it feels to take a deep breath. To feel the stretch of the lungs as they fill with air. It is refreshing and satisfying.


A little dramatic, I admit but it is very similar to how your furnace feels. Most forced air systems use a big fan to suck air in and push that air over a heat exchanging device and then blow that newly conditioned air throughout the home. The thermostat, usually located centrally in the home, calls for heat the furnace starts heating up. When the brains of the furnace decide the heat exchanging area has heated up enough the fan turns on. It is now the fan’s job to pass air over the heated area and blow that heated air throughout the home.

It is my job to look at furnaces and filters every day and as a general rule: people change their furnace filter when they move in and when they move out. When the filter is dirty the fan is forced to work much harder. Less air is moving over the heat exchanger so more energy is used. This also shortens the life of the entire unit.

Change your filters at least every 30 days in the cooling cycle and 60 days in the heating cycle at least. It will save you money on energy, extend the life of your system and give your poor furnace a welcome breath of fresh air.
