How can I prevent frozen pipes in the winter?

Frozen pipes are a common HVAC emergency in cold climates. Prevent them by:
  • Insulate Pipes: Insulate exposed pipes in unheated areas, such as crawl spaces, attics, and garages.
  • Seal Air Leaks: Seal air leaks and cracks in walls and foundations near pipes.
  • Keep Thermostat Consistent: Maintain a consistent thermostat setting, even when you are away, to keep indoor temperatures above freezing.
  • Open Cabinet Doors: Open cabinet doors under sinks to help prevent pipes from freezing.
  • Let Faucets Drip: During extremely cold weather, allow faucets to drip slowly to keep water moving and prevent freezing.
{If you suspect a frozen pipe, turn off the water supply and contact a plumber.. | Never attempt to thaw a frozen pipe with an open flame, as this could cause a fire.

How can I cool my home efficiently?

To cool your home efficiently:
  • Raise Your Thermostat: Set your thermostat to a higher temperature when you’re away. Consider using a programmable or smart thermostat.
  • Use Fans: Fans can circulate air and make you feel cooler, allowing you to raise the thermostat a few degrees.
  • Close Window Coverings: Keep curtains or blinds closed during the day to block out sunlight.
  • Limit Heat-Generating Activities: Avoid running heat-producing appliances (ovens, dryers) during the hottest parts of the day.
  • Annual AC Maintenance: Schedule yearly maintenance for your air conditioner to ensure it's running efficiently.
  • Plant Shade Trees: Planting trees around your home can provide natural shade and reduce heat gain.

What is a heat exchanger, and why is it important?

The heat exchanger is a vital component of a furnace. It prevents dangerous gases from mixing with the heated air, ensuring that exhaust gases are vented safely outside while clean, heated air is distributed throughout your home. A cracked heat exchanger is a serious safety hazard, as it can allow carbon monoxide to leak into your home. Annual furnace maintenance is crucial for checking the condition of the heat exchanger and ensuring safe operation.
