Improving Indoor Air Quality – Heating & Air Conditioning

Indoor Air Quality | Heating and Air Conditioning

According to the American Lung Society, poor indoor air quality is related to respiratory infections, lung cancer, and chronic lung disease. For those who already have lung disease the risk is even greater. The prevention of unclean air when possible is the best approach, with air cleaning devices augmenting the heating and air conditioning and the introduction of fresh air being other means of controlling indoor air pollution.

When a family member suffers from respiratory issues, clean air and proper humidity are a necessity. Cypress Heating and Air Conditioning can provide the assistance you need for improving the home’s indoor air quality. The heating and air conditioning system provide one means of improving the air that passes through it.

Pollutants in Homes

The most common pollutants are radon, combustion products, biological contaminants, volatile organic compounds, lead dust and asbestos.

Biological Pollutants

Biological pollutants include molds, bacteria, viruses, pollen, animal dander and particles from dust mites and cockroaches. These may cause infections, provoke allergic symptoms or trigger asthma attacks. Control measures include frequent washing of bedding to kill dust mites and careful cleaning along with controlling the moisture that promotes the growth of mold.


Sources of asbestos in the home environment include roofing, flooring materials and insulation for ceilings, walls, pipes and heating equipment.


Radon is a naturally occurring radioactive gas that can enter the home through cracks in the foundation floor and walls, drains, and other openings. Indoor radon exposure is estimated to be the second leading cause of lung cancer in the U.S.


Combustion pollutants come from sources such as fuel burning stoves, furnaces, fireplaces, heaters, and water heaters using gas, oil, coal, wood, or other fossil fuels. The most dangerous are the colorless and odorless gases of carbon monoxide (CO) and nitrogen dioxide (NO2). CO interferes with the delivery of oxygen to the body by substituting the gas for oxygen. NO2 irritates the mucous membranes in the eye, nose and throat and can cause shortness of breath and promote infections. The best way to control these pollutants is through proper use and to make sure combustion appliances are installed and maintained by certified professionals. A UL-listed CO monitor should be installed.

Air Filters and Cleaners

A high quality air filter or air cleaner, filters out airborne pollutants as air passes through the heating and air conditioning system. As air is forced through the air filter, dust and other pollutants is trapped, providing cleaner air and reducing heating and air conditioning repair.

However, not all heating and air conditioning systems are designed to pull the required amount of air through a high quality filter, such as a HEPA. For these systems, the use of a high quality filter can result in premature wear or dangerous overheating. A Cypress certified professional is your best source of the proper filter for your system.

An electronic air cleaner is an additional means of cleaning the air. These appliances give airborne pollutants a static charge, causing them to adhere to a collection plate and removing them from the circulated air in the home.

UV Germicidal Lights

A UV germicidal light targets biological contaminants, such as allergens, mold, viruses and bacteria. Installed in ductwork, they utilize safe amounts of ultraviolet radiation to destroy biological pollutants.

Humidifiers and Dehumidifiers

Improper humidity levels affect your comfort and health. Dry cold air leads to dry, cracked, itchy skin, dries out mucous membranes and the sinuses, leaving you susceptible to illness. The furnace won’t need to run as often when a humidifier is used, as a healthy level of humidity makes you feel warmer.

However, humidity levels that are excessive can cause uncomfortable temperatures, and can promote the growth of mold and other biological pollutants. In the summer, high humidity causes high temperatures to feel even hotter than it actually is. A whole-house humidifier in the winter and a dehumidifier in the summer will maintain a healthy and comfortable level of humidity.

Cypress’s qualified professionals can provide the humidifier just right for your home and family.

How Ducts Affect Air Quality

Your home may benefit from professional duct sealing service in multiple ways. Stopping air leaks in the ductwork saves energy by ensuring the conditioned air goes into the living space, and not outside of it. Properly sealed ducts will improve indoor air quality, by sealing out dirt, allergens and other pollutants.

Sources of Poor Indoor Air Quality in the Home

Home construction materials can contribute to poor air quality. The volatile organic compound (VOC) formaldehyde may be contributing to the poor air quality. Potential sources of VOCs in building materials include composite wood products, flooring and adhesives.
