What is a Heat Recovery Ventilator?

Heat recovery ventilators (HRVs) are among the most energy-efficient ventilation systems available. They pull fresh air inside, filtering it while expelling stale air. They also essentially “recapture” the energy of the outgoing, stale air and “give” it to the incoming air. Typical heat recovery ventilators can recycle about 85 percent of this warm or cool energy, taking strain off your HVAC system. There are a plenty of HRV models that attach to pre-existing ductwork.

Heat recovery ventilators accomplish the heat exchange inside the heat exchanger core, where the currents of incoming fresh air and outgoing stale air both pass. This is where the energy is collected and saved. The two different air flows, however, do not cross.

The U.S. Environmental Protection Agency and the American Lung Association recommend HRVs as some of the best ventilation systems on the market to improve indoor air quality and health. If you achieve energy savings with a tightly sealed home, your indoor air is probably not well circulated, leading to indoor pollution.

Heat recovery ventilators reduce indoor pollution from common factors including:

  • Off-gassing and fumes from building materials and carpets.
  • Fumes from household cleaners.
  • Excess humidity.
  • Mold, allergens, dust, and airborne bacteria and viruses.
  • Carbon dioxide exhaled by residents (each person exhales about 1 kg per day).

Fresh, filtered air can lead to vast improvements for many individuals plagued by recurring issues such as respiratory problems, headaches, allergies, lethargy and more.

Pre-installed ventilation systems in houses such as bathroom fans and stovetop fans can only go so far. These expel some heat, humidity and fumes, but also pull in pollutants from outside, dust particles from the attic, humidity, and radon, the second cause of lung cancer in the US after cigarettes. Opening windows won’t filter the  air or maintain your indoor temperature, but will strain your HVAC system

In the ongoing quest for energy efficiency, heat recovery ventilators are good investments, and can extend the life span of your HVAC system. If you’re thinking about improving your indoor air quality and want expert advice, feel free to call the professionals at  T. F. O’Brien. We’re happy to help.

Does Ductwork Mold Take Winter Off?

During the winter season on Long Island, it wouldn’t seem possible for mold to build up as dry heat goes constantly through your ducts. Your duct system is the guts of your furnace and cooling systems and must be kept healthy. While it’s true that mold is a bigger issue in the summer months, the winter season does not let homeowners off the hook when it comes to dangerous mold.

No matter the season, the inside of your HVAC system has its own micro-climate. There may be water leaks and humidity within your walls that are not obvious to the casual observer.  Because doors and windows are usually shut tight in winter, your family may be even more exposed to mold in the closed environment.

Mold in the New York area is such a big problem that a government  study  was funded to assess the extent of the issue faced by residents and propose some solutions. The report noted that mold is connected to serious symptoms of disease and discomforts such as allergic reactions, asthma attacks and skin reactions. If you or your family is suffering from allergy symptoms or even unexplained fatigue and tiredness, house mold could be the culprit.

The EPA (US Environmental Protection Agency)  recommends that you have your air duct system cleaned if “there is substantial visible mold growth…in your ducts or…other components of your heating and cooling systems.” The agency suggests that you have the system inspected by a professional to find and address the root cause of the problem. After your inspection and possible clean-up, think about signing up for a semi-annual HVAC maintenance plan to catch any problems, such as mold buildup, early. Remember that certain types of mold can be toxic. Act now to protect your family’s health and keep your home comfortable.

How to Control Your Home’s Indoor Air Quality

More and more people are being treated for allergy and asthma symptoms, and experts suspect that poor indoor air quality is one of the reasons. Some studies show that the average person spends as much as 90% of their time inside and that could be contributing to  health problems.

Homes today are being built tight to conserve energy. But, by sealing up the house there is very little fresh air coming in. Improving ventilation and installing air cleaners are practical ways that you can control the quality of your home’s indoor air.

The U.S. Environmental Protection Agency has been studying the problem of indoor air pollution and has issued a number of recommendations on how to keep your home safe. Running the vacuum regularly and dusting are practical ways to eliminate potential threats. Proper ventilation in bathrooms and kitchens is also recommended to vent excess moisture from showering and cooking. The EPA also advises not to permit smoking in your home and to store paints and pesticides outside of your living quarters.

Sometimes installing an exhaust fan is not sufficient to improve ventilation in the home. You may need an exchange unit which brings in clean air from the outside as it forces the stale air out. Some of these units can also retain hot or cool air and act as a dehumidifier to eliminate moisture. A T.F. O’Brien technician can determine what size unit would be appropriate for your home. This is also an excellent time to consider installing an electronic air cleaner which will  do a much better job of removing contaminants from the air than the typical furnace filter.

If you  are concerned about the indoor air quality in your home, take the EPA’s Care for Your Air Tour  which goes room by room through the typical house identifying hidden dangers.    You can connect to the EPA website by following this link.
