HVAC, Attic Leaks & Insulation – Winterization Part 3



Increase positive airflow, reduce the draft, seal areas where water can enter your home and fluff up your insulation for winter. Quick tips to prepare your home for winter.


  • It is best to replace filters every quarter (3 months) to allow maximum airflow. Enough dust can build up in three to four months that can reduce the blower productivity as well as add stress to your heating system.
  • Place a carbon monoxide detector on every floor of your home, including basements. Replace detectors every five to six years.
  • When you know that your air conditioner will not be used for an extended period of time, consider placing a cover over your unit to protect it from the elements. Be sure to check under the cover a few times during the winter as critters sometimes try to make it their home. Do not forget to remove the cover before you kick on the air conditioning.

Attic & Roof

  • The attic is a great place to save energy and add comfort to your home. Sealing your attic helps stop major air leaks and maintain the desired temperature inside your home. Combined with proper insulation, air sealing can help to avoid formation of winter ice dams. Seal any gaps or cracks with caulk or spray foam. If it is an area that could allow water to enter your attic, use a silicone caulk. As a general rule, use caulk for anything ¼ inch or smaller.
  • When it comes to your roof, the easiest and safest method of check shingles for damage or wear and tear is with a pair of binoculars. If you see any areas that seem abnormal, call a professional to take a closer look.

Insulate & Seal

  • Electrical outlets are often an overlooked area where cold air sneaks into your home. Insulate behind all electrical outlet wall plates, especially those on the windy side of your home. In most cases, spray foam or caulk should do the trick.
  • In crawlspaces and exterior walls look for areas that might allow cold air to rush in on a breezy day. It does not take much more than a crack to fill your crawlspace with cold air and create a draft in your home. Spray foam is a good way to seal off small cracks or gaps. In addition, you might consider insulating between the floor joists in your crawlspace. It is recommended that you contact a professional when adding insulation, especially if your crawl space is tight quarters.
  • When it comes to your attic, it is best to have a quality insured home professional assess whether you need additional insulation. Fiberglass and cellulose can compact over time reducing the R-value and what might look okay to a untrained eye could be an area of heat loss that a little insulation would resolve. Fiberglass and cellulose Insulation are like a fluffy coat that holds the heat into your home. When compacted the fluffy coat effect is reduced.


  • Uncover south facing windows to let the light shine in. Not only does this brighten things up during a season of reduced light, but it will also help heat your home on those cold sunny days.

When in doubt about anything home related, it is always best to contact a quality insured home professional.
