Time to have your heating system cleaned and checked so you can get the best performance from your boiler or furnace for when you need it the most.
- Remove any debris that may be blocking a power venter, fill pipe or fuel storage container.
- A smart thermostat is a great investment. It allows you to monitor your heat levels in your home while at work or away and can alert you to a potential problem if your heat drops.
- Make sure your heating vents or baseboard are in the open position, cleared of any blockage and pet hair.
- Check your air filters, clean air filters help with optimal air flow. For those who have pets, you may have to change filters more often.
- A ceiling fan can help a room stay warm while you are in it. Make sure the blades are going clockwise so as the heat rises it will push air out to the walls and back down again. Shut your fan off when not in the room as it will not help regulate the house.
- Anytime you put enclosed additions onto your home, finish a basement or increase the size of your family, you increase the fuel amount that is burned. Notify us of these changes so we can make the appropriate adjustments to your deliveries.
