How can I prevent frozen pipes in the winter?

Frozen pipes are a common HVAC emergency in cold climates. Protect your pipes from freezing 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 cold water taps to drip slightly to relieve pressure and prevent pipes from bursting.

{If you suspect a frozen pipe, shut off the main water valve and call a professional. | Thawing frozen pipes requires caution and should be done by a professional.

How do I maintain my air conditioner?

Regular maintenance is essential for keeping your AC unit in top condition. Perform these basic maintenance tasks:

• Change or clean air filters every 1-3 months.
• Clear debris from around the outdoor unit.
• Check and clean the evaporator coil (if accessible).
• Inspect refrigerant lines for leaks.

It's also advisable to have a professional HVAC technician perform an annual or biannual tune-up.

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

A heat exchanger transfers heat from the burned fuel to the air that circulates throughout your home. It separates the combustion process from the circulating air, ensuring that exhaust gases are vented safely outside while clean, heated air is distributed throughout your home. Regular inspection of your heat exchanger is vital for preventing CO leaks. Annual furnace maintenance is crucial for checking the condition of the heat exchanger and ensuring safe operation.

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, even at a higher thermostat setting.
• 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.
