How Does An ERV Work?

Maintaining good indoor air quality air is essential. Good home ventilation keeps your family healthier, and your home feels more comfortable. An effective ventilation system keeps unpleasant odors and harmful contaminants away. Toxins such as radon, formaldehyde, and VOCs can cause health risks. Inadequate ventilation generates humidity caused by showers, cooking, and laundry, resulting in a musty smell in your house. So, an ERV system is necessary to keep our homes fresh and breezy. The system is gaining popularity for its effectiveness in homes. Consulting an experienced HVAC company in Sacramento can help you decide on the same.

What is ERV?

ERV stands for Energy Recovery Ventilator. An ERV system provides fresh, temperature-controlled air into the home while expelling humid, hazardous air. ERV systems connect to the HVAC system’s channels. It uses two fans to draw fresh air into a house or business and exhaust stale air. An ERV system allows a building to receive fresh air while maintaining preconditioned heating or cooling.

An ERV uses exhausted air from your home to create the energy needed to ventilate your house. Since the air is pre-treated, your air conditioner and heat pump unit do not require working hard.

An ERV operates in both hot and cold weather. The ERV eliminates humidity and moisture from the fresh air entering your home during warm weather. It’s essential to check the humidity level in your home because mold thrives in a humid environment and is harmful to people with asthma.

The ventilator’s energy recovery wheel causes the air entering your home to cool as it passes through the ventilator. ERV system does not use ions or ozone because it uses a passive method of cleaning the air. So, the air you breathe is cleaner and safe for asthma patients.

Benefits of ERV System

  1. Improved Air Quality

Enhanced air quality is one of the biggest advantages of installing an ERV system. An ERV removes stale air and pollutants from your house. The ERV also filters external air, removing pollutants like pollen, dust, and other harmful environmental agents before they enter your home. Improved air quality leads to fewer respiratory problems.

  1. HVAC System Efficiency

The air entering your home is pre-cooled or pre-heated (depending on the season) when an ERV exchanges heat energy between the incoming and outgoing airstreams. Your HVAC system will use less energy to work, increasing efficiency and lower utility bills. However, scheduling inspection visits for air conditioning service in Sacramento results in a better HVAC system functioning in your home.

  1. Easy Maintenance

ERV requires less maintenance. Homeowners are required to change the filter every few months, which is not challenging work. You have experts who will clean and inspect your ERV system.


Technology advancement offers incredible benefits, making life easier. ERV system is one of the best developments that homeowners and business facilities could use for better indoor air quality.
