Winter is no joke in Southern Maryland. The last thing any homeowner in St. Mary’s, Calvert, Charles, Prince George’s or Anne Arundel County wants is for their heating system to stop working in the middle of a freezing night. But as the old saying goes: an ounce of prevention is worth a pound of cure. The team at Q-DOG Quality Discount Oil & Gas is here to help you keep your heating oil or propane tank filled and to provide guidance for best home heating practices.
Here are four simple ways you can keep your boiler or furnace in peak condition for the winter.
Heading out of town this winter? It’s fine to lower the heat, but please don’t turn it off completely. Set your thermostat to around 60°F and your fan to “auto” to keep air circulating safely without wasting energy.
Want even more control? A smart thermostat makes it easy by letting you monitor and adjust your home’s temperature from your smartphone or tablet — wherever you happen to be!
If your home uses a furnace, checking your air filter regularly is one of the simplest ways to keep your system running efficiently. Take a look at it at least once a month during heavy heating seasons. A dirty filter restricts airflow, forcing your furnace to work harder and use more energy. Replacing filters regularly improves indoor air quality, supports efficiency and extends your equipment’s lifespan.
If your home uses a boiler, it’s important to flush it once or twice a year. Sediment and sludge can build up over time, reducing efficiency and increasing wear and tear. To flush it, turn off the boiler, open the drain valve with a bucket underneath and let the hot water run until it’s clear. Then refill the tank with clean water. Check your boiler’s manual for detailed instructions or contact a trusted heating technician to handle it safely for you.
Don’t wait until the cold sets in to discover your heating system needs attention. Schedule your annual heating tune-up before winter arrives. A professional technician can inspect your boiler or furnace, identify potential issues and ensure everything is running efficiently and reliably.
While Q-DOG doesn’t perform system tune-ups, we’re happy to recommend an experienced and trustworthy service provider in your local area. Regular maintenance is one of the best investments you can make to avoid costly emergency repairs and keep your home warm all winter long.
Get the best possible price for your propane or heating oil, avoid run-outs and free yourself from needing to constantly check your tank gauge.
