air purifierIndoor air is often five times more polluted than outside air.  As people continue to spend more time inside than out, indoor air quality is a growing concern.  The EPA ranks indoor air pollutants among the top five environmental risks to public health.  The World Health Organization estimates that 30% of all new or renovated buildings have poor indoor air quality.  Fortunately, improving air quality is quite simple, straightforward and economical.  At Lea Heating & Air Conditioning, we have the solutions to make your home a healthy place to live and breathe.


Outdoor air ventilation is an essential component in reducing indoor air pollutants and improving air quality in the home.  The essence of sufficient ventilation is a continual flow of clean, fresh air, as well as the removal of stale, polluted air.  By expelling moisture created by cooking, cleaning, and other household chores, you can greatly reduce condensation and prevent mold and mildew.


Proper humidification levels are equally important in both hot and cold weather.  When humidity levels are controlled, you minimize unhealthy airborne pollutants.  Certain bacteria thrive in both dry and moist air, making each a potential cause of illness.  Insufficient humidity leaves the body vulnerable to infection, causes dry skin, bloody noses and static electricity.  It can also damage fine wood furnishings.  Too much humidity creates ideal breeding grounds for mold, mildew and dust mites.  Unstable humidity has been linked to fatigue, restless sleep, and an increased risk of asthma, pulmonary infections and allergies.  It can trigger eye irritation, headaches, nausea, fatigue and flu-like symptoms.  It is estimated that half of all upper respiratory illnesses are caused by poor indoor air quality.

Air Filters

Many homes have inefficient filters that trap less than ten percent of the particulate that is drawn into heating and cooling systems.  Once dust and debris overcome a standard household filter and begin to accumulate in the mechanical systems and ductwork, airflow is restricted, efficiency reduced, and air contamination is accelerated.  The average six-room house accumulates 40 pounds of dust each year.  That’s a lot for your air filters to handle.  Talk to Lea Heating & Air Conditioning to make sure you’re utilizing the very best and proper filters for your HVAC equipment.  Make sure to schedule yearly, comprehensive cleaning of your heating and cooling systems, as well as ductwork.
