Seasonal Maintenance Checklist for Your Furnace or Boiler

You’d think that summertime is when a responsible homeowner can relax about maintaining their furnace or boiler. But despite sunny skies and pleasant temps, it’s actually the perfect time to conduct some much-needed maintenance on your unit.

Why Maintain Your Boiler or Furnace in Spring and Summer?

It might seem like strange timing, but after many months of your unit working hard to keep your home heated, spring and summer is the perfect time to book a maintenance appointment. During this call, your technician can ensure your unit is running efficiently. When a cold snap hits, your unit will be ready.

Maintaining your furnace is a must after breakup and cottonwood season. Outside of checking the overall efficiency of your furnace, they can make sure the unit is clean, replace the filter, and make sure drainages are free of debris. This can make a huge difference in your energy bills and your family’s health.

Maintaining your boiler not only keeps your boiler working as expected, but also ensures that your unit isn’t releasing unsafe amounts of carbon monoxide. Carbon monoxide is odorless, colorless, and tasteless, so you won’t notice if your boiler is releasing amounts that could be poisonous to you and your family.
