HVAC Equipment Test

HVAC (Heating, Ventilation and Air Conditioning) are very often incorrectly oversized which causes the system to cycle on and off frequently, causing less comfort and inefficiency.  Exhaust ventilation is a particularly important health and safety concern in homes.  Proper mechanical ventilation is used to remove moisture, air pollution, or unwanted heat.


Replacing your existing furnace (heater) with a high-efficiency furnace can help save energy.  After air sealing and properly installing insulation, you can save money by reducing the size of your furnace.  The same holds true for the A/C system.  After air sealing and properly installing insulation, you can reduce the size of your A/C system and ducts to make your house more comfortable and energy efficient.


The components depicted in the picture to the left will be checked using state of the art diagnostic tools such as a combustion analyzer, duct blaster, and gas leak detector.  The coils and refrigerant lines will be checked to ensure their integrity, cleanliness and proper insulation.  Then, the system and air flow will be checked and calculated for proper sizing and rate of air exchange.

A/C systems consume about 30% of the electricity used in the US households, according to Southern California Edison.  Energy efficiency improvements in A/C systems can significantly lower operating costs of your home.

UV Air Purifier

APCO-in air handler-dual

Scientific studies have recently shown that UV light can kill 90% of microbes within 10 minutes and 99.9% after 24 hours.


The moisture and debris commonly found in HVAC systems provides an ideal breeding ground for mold, germs, fungi, and other harmful microbes.  Microbial contamination poses a major health risk to people who suffer from allergies, asthma, and other respiratory ailments, as well as to those who do not.   Numerous studies have confirmed that some diseases, including Legionnaire’s Disease, originate in, and are readily spread by, contaminated ventilation systems.  Airborne contaminants are drawn through the duct work of the central air conditioning system through return air registers.  According to ASHRAE, standard, throw-away fiberglass filters remove less than 7% of these particles, which means the rest settles in air ducts and also your lungs!  The leading medical authorities have now acknowledged poor and harmful indoor air quality as a major allergy and disease causing problem, which has prompted doctors and allergists to commonly prescribe furnace and air duct cleaning as a remedy.


The UV fresh air purifier can be installed in the ductwork of your central air system - one just above the air handler and the other mounted at the cooling coil.  This combination sterilizes microbial growth inside the air system, including mold, mildew, allergens, viruses and bacteria.  It is designed to help reduce airborne odors, toxic chemical vapors, germs and mold in your home.


This state of the art technology represents an entirely new type of air purifier.  The combination of germicidal UV light and activated carbon cells inside the air purifying unit make it uniquely effective at reducing volatile orgainic compounds VOCs in the air that you breath on a daily basis in your home, without producing any harmful ozone.  VOCs are  toxic chemical vapors found in your common household cleaning products underneath your kitchen sink, that cause odors and include toxic vapors such as formaldehyde and toluene.


If you question the need for air duct cleaning, take a look behind the return air grilles in the HVAC system of your home.  Many people have found that one glimpse into their air ducts provides all the evidence they need to initiate a through cleansing of their HVAC system.   Call today for a healthier home and a healthier you.
