Indoor air quality is more important than ever!
You may think that all heating, ventilation and air conditioning (HVAC) systems do is to heat or cool homes and commercial facilities so that everyone inside will feel comfortable. While this is a primary function, you should know that your system—when designed, installed and maintained according to high standards of quality—also contribute to the improvement of indoor air quality in homes, offices and commercial spaces.
What factors create poor indoor air quality?
Humidity. In a household, normal activities like bathing and cooking can create higher levels of indoor moisture—and consequently, humidity—when there are no means of mechanical ventilation provided (such as exhaust fans) or if the construction of the space allows poor ventilation (if there aren’t enough windows to let air move freely from inside to outside and vice-versa). In La and Southern California more homeowners who did not previously have HVAC in their homes are installing new equipment because of the climate change. We had a hot, humid summer and a winter where we are battling outdoor elements.
Airborne contaminants from outside
HVAC systems may draw air into the indoor space from outside, and this can be a problem when the outdoor environment has high levels of contaminants such as pollen, dust particles, spores from mold, and other things that can cause or aggravate allergies. With the recent Aliso Canyon Gas leak so close to home, as a Los Angeles HVAC company we take the quality of your indoor air very seriously.
Airborne contaminants produced inside
Your appliances could be creating the contaminants that spoil the quality of indoor air within your house. Your cooking appliances, such as gas cooktops, should come with provisions that help improve ventilation, which pertain to fans that send exhaust fumes outside the house. All gas-burning appliances (water heaters, furnaces, boilers, etc.) can produce carbon monoxide and other particulates that could remain and accumulate indoors.
How does my HVAC system contribute to indoor air quality?
Good HVAC systems come with air filters that remove particles from the air. This filtration function is a key element that can help protect the HVAC system, as well as maintain the good quality of air in occupied indoor spaces.
There are different kinds of air filters used in HVAC systems. Low efficiency filters keep out lint, dust, pollen, dust, bacteria, insects and soot, to prevent clogging in the system’s cooling and heating coils. Medium efficiency filters offer better filtration capabilities and are typically used in combination with low efficiency filters in indoor structures and environments that must be extra clean. There are also high efficiency filters that can be used without pre-filters, which makes them a cost-effective option, especially for larger spaces.
Of course, maintenance is a must to ensure that your HVAC system’s air filters remain in top-notch condition to effectively prevent airborne contaminants from finding their way indoors. A regular cleaning schedule should be observed to keep dirt from accumulating inside the ductwork and causing humidity levels to rise, which can lead to condensation that could create a moist environment that supports the growth and proliferation or microbiological organisms.
Be sure to ask about our anual maintnance program where we come out twice a year to clea, check and calibrate your Heating and air system. This will ensure your safety as well as give you peace of mind.
