A Breath of Clean Air
Do you ever have concerns about the quality of air inside your home? Most homeowners worry about outdoor allergens, but interior air quality can be even more problematic. That’s because allergens (among other harmful impurities) circulate repeatedly through your air ducts and around the house.
There are countless filtration and purification solutions available on the market. Consult with one of our specialists at A 100% Guarantee Heating and AC to discover which solution matches your family’s needs! Call our friendly staff today at 707-689-5128 and ask about our indoor air quality service in Vacaville, CA.
Concerns About Indoor Air Quality
There are two facets of air quality that most concern us as homeowners: purity and humidity. Both heavily impact our day to day comfort at home, but even more important is their effect upon our health. Without balanced humidity and clean air, our chances of physical side effects increase considerably.
Air Purity
Air Purification
Out of the two air quality factors, this one affects our health the most. Allergens, such as dust, bug debris, pet dander, and dirt, are typically trapped by the air conditioning units’ filter. However, when the filter becomes clogged (or simply lets particles slip through), these allergens spread around the house. If you regularly have to dust around the house, that’s a good sign it’s time to replace the filter.
The most concerning impurities in your home’s air supply are pathogens. Though they may not interfere with daily activities, pathogens (including bacteria, fungi, and viruses) may eventually be inhaled by a family member. This is especially problematic for individuals with weakened immune systems, though anyone can be affected.
Whole house air purification appliances target pathogens and other harmful contaminants in your HVAC system. The product typically utilizes a meshwork of filters combined with another neutralizing agent (such as germicidal light) to trap and kill pathogens. The result? Clean, worry-free air!
Humidity
Balancing Humidity
Have you ever experienced a winter where the air was unusually dry? This lack of humidity causes itchy skin, lung irritation, dry eyes, and even nose bleeds. Unfortunately, many families experience this overly dry air on a regular basis, inside their home. Not only does the dryness affect their health, it also pulls moisture out of wooden furniture, flooring, and other valuable property.
While portable humidifiers (and some hot tea) can soothe this problem, the relief is both short-lived and confined to a single room. Whole house systems, on the other hand, spread relief to every room inside your home. If your home regularly suffers from dry air, call the A 100% Guarantee Heating and AC team at 707-689-5128 and ask about this Vacaville, CA indoor air quality service!
Indoor Air Quality Testing
Do you worry about the quality of your home’s air? The first step to fixing the problem is scheduling an indoor air quality test. This testing reveal potential impurities in your homes HVAC system. More importantly, it allows you to make an informed decision regarding your next steps!
