What is carbon monoxide, and how can it affect my HVAC system?

Carbon monoxide (CO) is an invisible and odorless that is highly toxic when inhaled. Malfunctioning fuel-burning appliances, like furnaces or boilers, can produce carbon monoxide. A cracked heat exchanger in a furnace is a common source of carbon monoxide leaks in homes. HVAC maintenance checks can detect CO risks. CO detectors save lives.

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 allow warmer air to circulate around pipes.
  • Let Faucets Drip: During extremely cold weather, allow cold water taps to drip slowly to keep water moving and prevent freezing.
{If you suspect a frozen pipe, shut off the main water valve and call a professional. | Never attempt to thaw a frozen pipe with an open flame, as this could cause a fire.

How do I reset my HVAC system?
