Sources of Indoor Air Pollution

Did you know indoor air can be two to five times more polluted than air outdoors? Indoor air pollution can have significant and harmful effects on your health, according to the Environmental Protection Agency. Airborne pollutants cause contaminants that get into your lungs, causing respiratory issues, especially for the millions of Americans that suffer from allergies and asthma.

Air pollution can also damage your HVAC system and inhibit the way it functions, diminishing indoor air quality for Maryland homes and businesses. Fortunately, taking appropriate action can significantly improve indoor air quality – leading to a healthier environment for you, your family and co-workers.

Contaminants in HVAC Systems

Your heating and cooling system comes in contact with many types of toxins on a daily basis. Sources of indoor air pollution, include:

  • Mold and mildew
  • Bacteria and viruses
  • Tobacco smoke
  • Dust and dirt
  • Pet dander and hair
  • Pollen
  • Home furnishings
  • Cleaning products
  • Chimneys and stoves
  • Asbestos

Over time, indoor air pollution builds up in your HVAC system and impact the system’s performance, which can lead to health problems, expensive repairs or even replacement.

Protect Your HVAC System From Pollutants

The easiest way to limit indoor pollutants in your home or business is to avoid exposing areas to the common contaminants listed above. But, inevitably, indoor spaces will be exposed to some level of indoor pollutants no matter how hard you try to prevent them. There are steps homeowners and businesses can take to improve the health of their HVAC systems.

How to Improve Indoor Air Quality

Grove Heating & Cooling has several solutions for improving indoor air quality.

Regular maintenance tune-ups

One of the easiest ways to protect your HVAC system from indoor pollution and other harmful toxins is through regular maintenance of your heating and cooling system. Maintenance should be performed twice a year – in the spring and fall.

Our NATE-certified technicians will check all of your system’s HVAC components and parts and clean them of any excess debris that can cause damage and shorten the life of your system. This will improve the health of your HVAC system and prevent it from circulating harmful particles in the air.

Air purifiers

Media air cleaners are another level of protection for your HVAC system. Normal air filters are about an inch thick, but a media air cleaner is typically about 4 to 5 inches thick and captures smoke, bacteria, pollen and other harmful contaminants from entering the system.

Media air cleaners are typically installed on or near the furnace, and they should be replaced about once or twice a year.

Complementing your air cleaner with a high-efficiency air purifier is a great way to provide extra protection.

Whole-home dehumidifiers

A whole-home dehumidifier works well in areas with high-humidity levels. Excess moisture indoors can lead to mildew, mold and dust mites that can grow in your HVAC system. If the air in your home is thick and sticky, a dehumidifier can provide the relief you need.


On the opposite end, too little humidity can also be harmful to your health and comfort. Dryness can lead to several health problems, including dry skin and bloody noses. Low humidity levels can also cause the flu and other viruses to live longer outside the body.

Installing a humidifier adds water to the circulated air to improve comfort and reduce the chance of getting sick. Increased humidity can also save you money on your energy bill because it provides an insulating effect that allows you to lower the thermostat.

Duct cleaning

Duct cleaning creates an overall healthier environment by reducing dust and other particles that would otherwise circulate around your home. Air ducts can contain harmful contaminants, including mold, mildew, pollen and bacteria.

Removing these harmful toxins will result in a more efficient system by reducing the buildup that can cause the system to work harder.

Updating Your Thermostat

When you upgrade your existing thermostat to a smart thermostat you can set and maintain the desired temperature you need to stay comfortable. Features on smart thermostats include humidity seniors that allow you to set the right humidity level in your home.
