Simple Tips to protect HVAC in winter from snow and Ice


In the winter, it is important to protect your HVAC from freezing. Following these tips can keep your system running smoothly and avoid costly repairs.

  • Avoid using fans near windows and doors. When your fan blows warm air directly onto a window or door, it may freeze the glass and trigger the need for repair. Try to use fans only near ceiling vents or exhaust grilles.

  • Clean ductwork regularly. Dirty ductwork can lead to dampness buildup and mold problems. Have your ductwork cleaned periodically to avoid these issues. Even if you don't notice moldy smells, it's best to get rid of the problem before it worsens.

  • Install thermal blankets. Thermal blankets help insulate your air conditioner from extreme heat. These blankets are often recommended for use over the coils of an air conditioner to provide additional protection .

  • Use dehumidifiers. Dehumidification systems reduce humidity levels in the air around you. That way, moisture won't build up in your home, causing potential damage to your HVAC equipment. You should consider purchasing dehumidification systems if you live somewhere where humidity levels tend to rise above normal.

  • Insulate attic space. Attics are prone to high-temperature extremes, especially at night. Ensure to add insulation to the attic space to decrease the risk of overheating.
