More than ever, it is important to be sure your home is properly ventilated. Why?
Homes are different now.
Not that long ago, houses were so drafty that ventilation was hardly needed: fresh air found a way inside and stale air leaked outside. But today, newer homes — or older homes that have been well insulated — can be so “tight” that unhealthy air remains locked inside.
from combustion appliances, like stoves and fireplaces and older heating systems.
from seasonally damp outside conditions or from the operation of an air conditioning system.
(such as mold, kitchen odors, pet dander and plant pollen) within your home ’s air can be up to 10 times more contaminated than the air outside.
POSITIVE Bring fresh air inside the house by a fan. Con: that incoming air is going to be hot in summer, cold in winter.
NEGATIVE Exhaust the polluted air to the outside, again by a fan. Con: conditioned air (from your heating or cooling system) is now “lost.”.
BALANCED Bring in — and exhaust — approximately equal quantities of fresh outside air and polluted inside air, respectively.
While most of our customers find that a balanced system is an ideal solution for them, we don’t take that for granted. There are some conditions where a positive or negative ventilating solution will be adequate.
First we test. Using advanced monitoring equipment, a Central Home Energy technician measures the level of existing “natural” ventilation (primarily, through doors and windows) as well as the quality of your indoor air. Afterwards, we’ll give a full report, show you your options, and answer any questions that you may have. Sometimes our recommendation might be as simple as improving a bathroom fan (“negative” ventilation). Or it may be that an HRV or ERV balanced ventilation system would be ideal for your family:
Heat-recovery ventilators (HRV) draw fresh air into a home while simultaneously exhausting stale air from the home. During this exchange, the two airstreams pass through a core within the unit where a portion of heat from one air stream is transferred into the other (usually the indoor air in winter; and the outdoor air in summer).
Energy-recovery ventilators (ERV) work similarly to an HRV, except an ERV allows a portion of the moisture in the more humid air stream (usually the indoor air in winter and the outdoor air in summer) to be transferred to the dryer air stream.
Both of these systems are balanced; working within the home’s HVAC system to facilitate proper distribution of fresh air throughout the living environment. The systems Central Home Energy installs are up to 80% efficient and will bring a world of new comfort and healthy living to your family.
