Keep Air Fresh with a Heat Recovery Ventilator

Keep Air Fresh with a Heat Recovery VentilatorFresh indoor air is vital for maintaining a healthful and comfortable home. Yet, the vast majority of homes in southern California have poor indoor air quality (IAQ). A major factor affecting IAQ is a lack of daily whole-home ventilation. Without daily air exchange, indoor air becomes stale and stagnant. If you are concerned about the quality of the air inside your San Diego area home, keep reading to learn how a heat recovery ventilator can help.

Heat Recovery Ventilator

A standard balanced ventilation system utilizes two fans that deliver an equal volume of fresh air and exhaust air. By supplying balanced ventilation, you eliminate the risk of pressurizing or depressurizing your home, which can cause backdrafting of combustion appliances and disrupt airflow from the supply registers to the return grilles.

A heat recovery ventilator is a whole-home, balanced ventilation system. The advantage of choosing this type of ventilation system is that it uses the heat energy of your home’s indoor air to preheat cooler fresh air supply. This helps minimize your heating bills to enjoy fresh air during the heating months.

During warmer weather in the San Diego area, your heat recovery ventilation system absorbs from fresh supply air so that your A/C doesn’t have to work as much (or at all) to ensure your home has fresh air.

Why Home Ventilation is Important

Newer homes that were constructed with more energy-efficient materials and building methods are excellent for saving energy. Though, as homes are designed to be tighter and more efficient, IAQ tends to suffer. This is also true of retrofitted older homes with insulation and air sealing upgrades.

The problem is that contaminants and moisture become locked inside tight homes when ventilation is lacking. Heat recovery ventilators solve this dilemma and allow you to enjoy fresh air any time of year without significantly increasing the load on your HVAC system.

Think Indoor Air Isn’t as Polluted as Outdoor Air? Think Again

Think Indoor Air Isn't as Polluted as Outdoor Air? Think AgainGiven the amount of vehicle traffic that contributes to bad air quality in San Diego, it’s easy to assume that indoor air pollution is minor compared to what’s outside. But in reality, the air you breathe indoors may be among the most toxic you encounter, according to the Environmental Protection Agency (EPA).

A recent nationwide study found that while 91 percent of survey respondents believe high air quality is essential for good health, 76 percent used products in their homes that degrade indoor air quality (IAQ). A full 57 percent didn’t change the HVAC system’s air filter regularly to alleviate airborne allergies or control airborne particulates.

Achieving healthy indoor air isn’t difficult or expensive, especially if you use your central cooling and heating system as part of a whole-house approach. Here are some tips to start with.

Improve Ventilation

Use exhaust fans in the kitchen and bath to pull out excessive humidity. You can also use an energy recovery ventilator (ERV) as part of your HVAC system to exhaust stale indoor air and replace it with fresh air. ERVs capture the energy in the outgoing air and put it into the incoming air, making them an energy efficient approach to reduce indoor air pollution.

Reduce the Amount of VOCs in Your Home

Cleaning products, paint, new flooring, many cleaning products, dry cleaning and vinyl products contain volatile organic compounds (VOCs), which can lead to damaging health effects. Look for products with a clean air label or labeled as no or low VOCs. Ultraviolet (UV) lights inside the air handler and ductwork can neutralize the toxicity of VOCs and help control the spread of viruses and bacteria.

Change Air Filters Regularly

Change the HVAC system’s air filter on a regular basis to keep IAQ higher. A clean filter will trap more airborne particulates like pollen, dust and pet dander, reducing the severity of allergies and asthma.
