High Winds Across The United States Affecting Indoor Air Quality

The high winds that have been seen from coast to coast in the U.S. lately are having a negative effect on home A/C and HVAC systems. An air conditioning unit requires regular cleaning and maintenance to function efficiently and effectively, and to reduce repair costs throughout its years of service. Excellent indoor air quality and energy efficiency depends on the condition of the air conditioner; therefore, neglecting the necessary maintenance is unwise. Dust mold and allergens can cause serious health problems, so cleaning the dust and debris from the HVAC components and machinery should be addressed immediately.

In essence, maintaining your air conditioner will save you money and extend the unit’s life. Some of the components that require regular maintenance include:
• Filters
• Coils
• Coil fins
• Condensate Drains
• Window Seals

Routinely cleaning and replacing air conditioner filters is the most important task that will ensure efficiency. When the filter is dirty or clogged, there is a reduction in the normal air flow; therefore, the system has to work harder, which requires more energy. According to, replacing a clogged or dirty filter can lower energy consumption by between 5% and 10%. Additionally, the air that manages to pass through the filter may carry dust and dirt particles into the evaporator coil, thus impairing its heat absorption capacity.

It is important to replace the filter at least once every three months, and every month or two during the heavy use season; however, some types of AC filters are reusable. Filters are available in many types and efficiencies. One should seek the services of a professional technician to replace the AC filter.

Over the AC unit’s months and years of service, the evaporator and condenser coils collect a lot of dust and dirt particles, especially if the filter is clogged or dirty. The dirt insulates the coil and reduces its heat absorption capabilities. To counter this issue, one should check and clean the coil every year. When it comes to outdoor condenser coils, the outdoor environment plays a very big part. It is vital to minimize the debris and dirt near the unit by cleaning the area, trimming foliage, and ensuring there is sufficient airflow around the condenser unit.

Coil Fins
Sometimes, the aluminum coil fins can bend and block the air flow through the coil, thus reducing efficiency. When this happens, one should use a fin comb to straighten the fins into their original position. Fin combs are available in most air conditioning wholesale outlets.

Condensate Drains and Window Seals
Maintenance of the condensate drains involves passing a taut wire through the drain channels to enable the unit to reduce humidity and the excess moisture, which may discolor the carpet and walls. In addition, it is important to check the seal between the window frame and the air conditioner to ensure there is no gap. In certain cases, moisture damages the seal, thereby allowing cool air to escape.

An experienced HVAC technician can find and fix any problems affecting the air conditioning unit, including HVAC vent cleaning. Therefore, it is important to use a professional heating and cooling professional to clean, maintain and perform your home air quality testing.
