ERV Air Exchange System Installation
An Energy Recovery Ventilator (ERV) brings fresh outdoor air into your home while recovering energy from the stale air it exhausts, keeping your indoor environment healthy without wasting the heating or cooling you have already paid for. Southern Maine Heat Pumps installs ERV air exchange systems that work seamlessly with your heat pump to maintain excellent indoor air quality, control humidity, and reduce allergens and pollutants year-round.
Modern homes across Cumberland County are built tighter than ever before, which is excellent for energy efficiency but can create indoor air quality challenges. Energy Recovery Ventilators (ERVs) are the solution that Southern Maine homeowners need to enjoy both energy efficiency and fresh, healthy air. An ERV system continuously exchanges stale indoor air with fresh outdoor air while recovering energy from the outgoing air to precondition the incoming air. This means you get fresh, filtered air year-round without sacrificing the efficiency of your heat pump installation. Whether you live in Portland, Gorham, or anywhere in Cumberland County, an ERV system is one of the smartest investments you can make for your family's health and comfort.
ERV systems are particularly important for homes with ductless mini-split heat pumps or other high-efficiency HVAC equipment. When your home is well-insulated and air-sealed, pollutants, moisture, odors, and carbon dioxide can build up without proper ventilation. An ERV addresses this by providing continuous, balanced ventilation that removes these contaminants while recovering up to 80% of the energy from the exhaust air. This is especially critical during Maine winters when opening windows is not practical. From Westbrook to Scarborough, homeowners trust Southern Maine Heat Pumps to design and install ERV systems that work seamlessly with their existing HVAC equipment.
At Southern Maine Heat Pumps, we specialize in integrating ERV systems with your home's heating and cooling infrastructure. Our team has extensive experience installing ERVs in both new construction and retrofit applications across Cumberland County. We work with industry-leading manufacturers to ensure your system is quiet, efficient, and perfectly sized for your home. And with our annual maintenance plans, your ERV will continue delivering fresh, healthy air for years to come. Better indoor air quality is not a luxury—it is a necessity for modern, energy-efficient homes in Southern Maine.
Better Air Quality for Tighter Homes
Energy-efficient homes in Cumberland County are built to be tight and well-sealed, which is excellent for reducing heating and cooling costs. However, this can trap stale air, excess moisture, cooking odors, VOCs, and other indoor pollutants inside your living space.
An ERV system solves this problem by providing continuous, balanced ventilation. It exhausts stale indoor air while bringing in fresh outdoor air, and it does this while recovering energy from the outgoing air to precondition the incoming air. The result is healthier indoor air quality without sacrificing the efficiency of your heating and cooling systems.
