Preparing Your HVAC System for Harsh New Hampshire Winters

In the Northeast, cold winters and generous snowfall are constants we can rely on. As we look ahead to the winter of 2023-2024, there is conflicting information about what to expect. El Niño predictions suggest a milder, wetter season, while the Farmer’s Almanac foresees “below-average temperatures and an abundance of snowstorms, sleet, ice, and rain” in New England during the coldest months of January and February. While nothing is certain, experience has taught us that harsh weather is inevitable at some point during the winter. With the promise of snow and freezing temperatures, it is essential to ensure that your HVAC system is prepared to keep your home warm and comfortable, no matter what lies ahead. So, the question is: how can you achieve that?

Scheduling regular furnace or heat pump maintenance appointments with your Lakes Region HVAC technician helps detect potential issues and prevent costly breakdowns.

First Things First

Begin by scheduling a comprehensive inspection and maintenance appointment with a licensed HVAC technician. A professional service will encompass an evaluation of your entire heating system, including indoor and outdoor units, ductwork, and your thermostat. Investing in this inspection ensures the early detection of potential issues, preventing costly breakdowns during the coldest part of the year. During the inspection, your technician will:

  1. Replace your HVAC system’s air filters. Old, dirty, or clogged filters reduce airflow and can lead to higher energy bills. In the winter, when demand is high, ensuring optimal airflow is vital to prevent breakdowns and keep heating costs low. Additionally, clean filters enhance indoor air quality, a top priority when people are typically spending more time indoors.
  2. Verify that your thermostat is functioning properly.
  3. Inspect ductwork for leaks or blockages that can result in heat loss and reduced efficiency. If cleaning is necessary, they will assess the severity and provide guidance on either handling it yourself or hiring a professional duct cleaning service.
  4. Clean and examine the furnace for issues such as worn-out parts, ignition problems or carbon monoxide leaks.

If your HVAC system includes a heat pump, the technician will test it to ensure effective warm air delivery.

Sealing drafts in your home keeps the warm air inside during cold weather months and allows your heating system to work efficiently and effectively.

Be Proactive

Once professionals have inspected and tuned your system, you can take several straightforward steps to stay warm and maintain your HVAC system’s efficiency this winter:

  1. Inspect your home for drafts, particularly if you live in an older home. Seal any draft-prone areas, such as doors and windows, using caulk, weatherstripping or window film.
  2. Enhance insulation in your attic or crawl spaces to prevent overworking your system.
  3. Ensure your outdoor unit is free of debris and fallen leaves.
  4. Consider installing a cover for your outdoor unit to protect it from winter’s harsh conditions.

Taking these proactive steps before the cold weather arrives can give you peace of mind and allow you to enjoy all that New Hampshire winters have to offer while staying warm and comfortable in your home.
