How to Install Home Insulation

In a typical home, improperly insulated walls can account for up to 20% of heat loss. Concrete, stone and masonry foundations often have less insulating value and can be improved witht the use of additional insulation.

How to Improve Home Air Quality

Poor home air quality has been linked to a variety of health-related issues including allergies, headaches, chronic fatigue and insomnia. By improving the quality of air in your home, you can help improve your health and reduce dusts and odors.

Your home’s air quality is affected by appliance combustion, dust mites, house dirt, home-office products, household cleaning products, personal-care products, humidity, improper ventilation, molds, new home construction (glue, carpets, paint, etc.), pet dander and fur, pollen, second-hand smoke and traditional fireplaces.

Eliminate Contamination

There are many ways to improve your indoor air quality.

  1. Remove any sources of indoor contaimination such as cigarette smoke, mould or mildew.
  2. Ensure your home is adequately ventilated.
  3. Use a high-quality filter in conjuction with your forced air furnace or consider having an air exchanger installed in your home.

Fans and Dehumidifers

Other common air quality problems can be created by too much moisture in the home. Excess moisture can lead to molds and dust mites. To control the humidity, use an exhaust fan and dehumidifier. The Home Depot carries a huge selection of models, many of which have a quiet-run feature.

High-Performance Air Filters

Simple, inexpensive paper filters are designed to protect the mechanics of your furnace, but will do little to improve the quality of air in your home. Typically, the more expensive the filter, the better performance and heightened air quality.  Electrostatic filters rate highest because these systems remove even the smallest air particles.

Air Exchangers and Heat-Recovery Ventilators

Air exchangers improve indoor air quality and reduce excess humidity by continually exchanging stale, polluted indoor air with fresh, revitalized outdoor air. They also expell excess humidityand lower the risk of window condensation. This helps prevent damage and deterioration to your home. However, air exchangers have no heat recovery component.

If you live in a colder climate where home heating is essential, take a look at heat-recovery ventilators as an air exchanger. This system expells stale warm air and the heat recovery core warms the incoming, fresh colder air before distributing it throughout your home.

If interested in an air exchanger or heat-recovery ventilator, consult your local The Home Depot associate. Both systems often require professional installation.

Checking Your Air Filter

  • Turn off the power to your furnace
  • Remove your old filter and measure the size of the filter required
  • Find the correct size filter at your local The Home Depot
  • Follow the manufacturer’s instructions to install your new filter

Make a note of the date you installed your filter. As a rule of thumb, replace your furnace filter about every three months. If you have pets or a dusty environment, check your filter often. You may need to change it more frequently.  Changing the filter means your furnace doesn’t have to work as hard, saving you money on electricity bills.
