Cooper Climate Control can help you control indoor allergens by regular maintenance on your air conditioning unit. As we tell our client’s when we come into their homes, it is very important to change filters regularly as 
recommended or every two months during use. We also mail out Recommendation Letters after every service informing any maintenance instruction if needed.
When we inspect your system pertaining to assisting you & your family to control allergens we first check for mold. But if you suspect mold may be growing inside your air conditioning system, you may want to consider having the air ducts cleaned. If you see mold particles growing near the ducts or on the components of the system or if you smell a musty or moldy odor coming from your vents, give us a call so that we can check for an accumulation of mold.
The sources of the pollution can be any number of things, one of which is allergens such as dust mites, mold, and pollen.
Common Indoor Allergens
Common indoor allergens include:
- Mold
- Pet dander (skin flakes), saliva, and urine
- Cockroach droppings
- Pollen
When these particles become airborne, you can breathe them in and experience an allergic reaction.
The heating ventilation and air conditioning unit in your home can both harbor and spread mold and other allergens.
Optimize Your HVAC System
We explain to all of our client’s that filters can help minimize exposure to allergens from your heating and air conditioning unit. Filters can be built into the ducts in your home, but keep in mind , not all filters are created equally. Our technicians can tell you specifically which filters your unit will need due to the effectiveness of filters is measured in something called MERVs which is (minimum efficiency recording value). MERVs range from 1 to 20, with 20 providing the highest level of particle filtration.
Types of HVAC Filters
Here are other things to know about HVAC filters include the following:
- Flat panel filters. These types of filters are put in place by most furnace manufacturers, generally have a rating of one to four MERVs, and are designed to protect the furnace, not improve indoor air quality.
- Medium efficiency filters. These pleated furnace filters have a higher surface area and, therefore, filter more particles out of the air. Their MERV rating ranges from five to 13.
- High efficiency filters. These filters have MERV ratings of 14 to 16, and remove even smaller particles than pleated filters.
- HEPA filters. High-efficiency particulate air (HEPA) filters have MERV ratings of 17 to 20, and are not typically recommended for centralized home HVAC systems unless major – read expensive – updates are made to the system. This is because high energy and HEPA filters can be so efficient that your HVAC system ends up requiring more energy to power the fan that gets air circulating.
Since higher efficiency and HEPA filters tend to put so much stress on your heating and air conditioning unit, we recommend medium efficiency filters for most of our clients. They are reasonably effective at removing small to large particles.
