Indoor Air Quality

The Key to Complete Comfort at Home

Americans spend 84% of their time indoors, whether it be at home or in an office according to the EPA.  But did you know that the air indoors can be 2 to 5 times worse than outdoors?  This is because many buildings and homes have poor air exchange rates due to improperly designed HVAC systems, trapping dirty air inside faster than new air can replace it. Here’s a video we put together to help explain:

How Does Indoor Air Quality Affect My Comfort?

Especially in the Northeast where we spend a large chunk of our year bundled up inside, air quality can have a dramatic effect on your health and comfort.  This is especially harmful to those in your family who suffer from seasonal allergies or asthma.  Another factor affecting your air quality is humidity control.  Common symptoms such as frequent nosebleeds and dry skin or hair indicate too little humidity in the air.  The presence of mildew and mold, damp feeling on floors and furniture, or musty smells usually indicate too much humidity.  The humidity level of your indoor air can even pose a risk to your health when it comes to how often you get sick from seasonal colds and flu!

Let’s Talk About Your HVAC System

For many, HVAC (Heating, Ventilation, Air Conditioning) systems are just boxes in their basement or outside that give them heat or cooling when they adjust their thermostat.  However, that’s only half of the total picture.  Ventilation and “conditioning” are crucial but often ignored components to keeping your family comfortable and healthy indoors.  Especially in new homes, which are tightly sealed to prevent energy loss, can have a negative impact on your home’s indoor air quality if their HVAC systems are not properly designed or installed.  Your home’s ductwork and ventilation systems are crucial for providing enough airflow to fuel your heating systems and appliances and keep your indoor air from becoming stale.  Likewise, air passing through your HVAC system can usually be treated by filtration and humidity control systems as we mentioned above, which can provide dramatic improvements to your comfort indoors.

Solving Cold/Warm Spots In The Home

Indoor air quality also extends to the actual temperature of your home.  This is because warm or cold spots in your home are almost always the result of a poorly functioning or improperly designed HVAC system.  Lack of airflow can cause cold rooms or areas in your home, whether it’s a new addition which is extra square footage your system was designed to accommodate, or if your ductwork is undersized, restricted, or damaged in some way.  Likewise, bad HVAC design can lead to certain areas of the home getting “blown out” by heat.

Cooling Services | Just Call Heritage

At Heritage, all of our new system installations take ductwork design very seriously.  You can be sure that every system we install has been calculated to provide your family with the perfect level of comfort for your needs.  For existing systems, fixing trouble areas can be more involved but not impossible.  Our licensed HVAC technicians are able to inspect and advise you on improvements to your system, such as duct repair*, adding a standalone mini-split ductless unit for home additions, or installing a multi-zone heating system.
