Air Conditioning Improves Indoor Air Quality

Air Conditioning improves air quality in Matthews

Cool power. Replacing dirty air filters and cleaning AC coils are two maintenance tasks that keep an AC system working at peak efficiency.

When it's hot and muggy outside, air conditioning keeps you cool and dry indoors. A well-functioning AC system is especially important to people with allergies or asthma, who take refuge indoors when pollen counts and ozone levels are high.

Contact us today to evaluate your home's air conditioning system to ensure it is efficient and that it is the best option for your home. We service Mount Holly, Fort Mill, Huntersville, Gastonia, Matthews, Hickory, Denver, Lincolnton, Rock Hill, Gaffney, and all nearby locations.

Reduce Allergy and Asthma Symptoms with the best Air Conditioning System

If you rely on air conditioning to reduce allergy and asthma symptoms, be sure your system is equipped with an efficient filter, such as one with a MERV (Minimum Efficiency Reporting Value) rating of 8 or more. As your trusted air conditioning contractor, we will first make sure your air conditioning unit can handle using a high-efficiency filter, such as one with a MERV of 13. If the blower is not powerful enough, you may end up restricting the system's air flow, reducing the system's efficiency, and possibly overworking and damaging the condenser. Also, be sure to replace your filter frequently so as to strengthen its efficiency.

A clogged air filter decreases your system's efficiency because it restricts air flow. In general, filters with 4 to 5 inch deep pleats last longer than standard 1 inch deep filters, which may need to be changed as frequently as every month. You may be able to retrofit a deeper filter cabinet to your ductwork, but check with an HVAC contractor first.

APCO Whole-House Air Purifier

The award-winning APCO system (Advanced Photocatalytic Oxidation) uses a unique combination of UVC light and activated carbon cells to reduce airborne odors, mold, germs, and allergens throughout the entire home.  ACPO is installed in the duct work of the central air system so it can remove airborne contaminants as they pass by.

Why Choose APCO?

  • Award-winning technology: APCO is a winner of the prestigious AHR Innovation Award, the highest honor of the HVAC industry.
  • Guaranteed for life: APCO is so confident in the quality of their design and manufacturing that the product comes with a lifetime warranty on all parts except the UV lamp.
  • Ozone-free: Many air purifiers that claim to reduce odors do so by generating harmful ozone. APCO not only doesn't produce ozone, it actually removes it from the air!

Clean Air Ducts Make a Difference

In addition, be sure that HVAC air ducts are clean. A thin coating of dust on the inside of duct walls may not pose an air quality problem, but accumulations of dust at supply registers are a sign the ducts need cleaning. Avoid the use of fans because they stir up dust and associated allergens.

As a bonus, air conditioning reduces excessive humidity, a condition that fosters the growth of other allergens, such as mold and dust mites. The recommendation is to keep the humidity in your home below 50 percent.
