Sealing air leaks and adding insulation are two common ways to improve the comfort and energy efficiency of your house. The problem: if your home is too tightly sealed, this prevents fresh air from getting into your house, which can cause poor indoor air quality, making allergy and asthma conditions worse. To solve this issue, you might need a ventilation system. An energy recovery ventilator (ERV) removes stale, polluted air from the home and replaces it with fresh outside air.
National Radon Defense Dealers are trained to install an ERV to work with your existing heating and cooling systems. To find out if an ERV system is the right solution to your indoor air quality problems, contact your local contractor today for a consultation and estimate!
Actual results from indoor air test before and after installing the Energy Recovery Ventilator. The chemicals (VOCs) in the air were reduced from very high levels (3,600 ppm) to very safe levels (400 ppm). The radon and carbon monoxide levels were also greatly improved. The customer also reports their home smelling fresh and clean.
An energy recovery ventilator reduces radon levels by adding fresh air and creating positive air pressure. Negative air pressure in lower levels of homes and building create a force that pulls soil gases including radon into the structure. If we can reduce this negative air pressure, we can thus reduce your radon levels. Also, supplying fresh air makes a huge impact. These two features of an energy recovery ventilator make it a great solution for reducing radon and other indoor air contaminants in your air.
National Radon Defense has installed an energy recovery ventilator as a solution where traditional active soil depressurization wasn’t viable and/or cost effective. These situations can occur in homes with inaccessible crawl spaces, difficult slab accessibility, earth homes, HVAC returns under the slab, and other tough scenarios. The ERV has also proven to be a great option in schools and commercial buildings too. Many of our customers prefer the benefits of an ERV over traditional radon mitigation.
When air leaks are sealed to make homes more energy efficient, this eliminates a way for contaminants to escape. Pollutants that are trapped in your home can cause poor indoor air quality. Signs of poor ventilation include moisture buildup on windows or walls, stuffy air, and lingering odors. If you have any of these issues in your home, you should consider a ventilation system. A ventilation system circulates air throughout the house using the existing forced-air system or specially-installed ducts. The system pumps stale air out and replaces it with fresher outside air.
Unlike ordinary ventilation systems, the energy recovery system handles both exhaust and fresh airstreams while also moderating temperature extremes and humidity year round, and removing excess carbon dioxide, radon, formaldehyde, and other gaseous pollutants. In the winter, the fresh, cold, dry outside air is preheated and humidified by the outgoing warm interior air. In the summer, the fresh, warm, humid outside air is pre-cooled and dehumidified by the outgoing air-conditioned interior air. No matter what the season, the pollutants go out and fresh air stays in, with no wasted energy.
When you're inside your home, make sure you're always breathing fresh, healthy air with the best ERV system. Contact your local National Radon Defense Contractor today to schedule an appointment with an indoor air quality specialist!
