Breathe Fresh, Clean Air Without Sacrificing Energy Efficiency

Modern homes and buildings are built tighter than ever to maximize energy efficiency. While this keeps heating and cooling costs down, it also traps stale air, moisture, odors, and indoor pollutants (like VOCs, dust, and allergens) inside.

At Ross Tech 360 LLC in Arundel ME , we specialize in the professional installation of Heat Recovery Ventilation (HRV) and Energy Recovery Ventilation (ERV) systems. These advanced systems continuously exchange stale indoor air with fresh, filtered outdoor air—without losing the heated or cooled air you’ve already paid for.

Think of an HRV or ERV as the "lungs" of your home. The system uses a network of ducts to pull stale, polluted air out of your home (typically from kitchens, bathrooms, and laundry rooms) while simultaneously drawing fresh, filtered air in from the outside.

Both air streams pass through a specialized core inside the unit. They never mix, but the temperature (and in the case of an ERV, moisture) is transferred from the outgoing air to the incoming air. This means you get a constant supply of fresh, tempered air without the massive energy penalty of opening a window in the dead of a Maine winter or the height of summer.

Choosing between the two depends on your specific climate and humidity needs:

• HRV (Heat Recovery Ventilation): Best for colder climates like Southern Maine. It transfers heat from the outgoing stale air to warm up the incoming fresh air during the winter. In the summer, it pre-cools the incoming hot air. It is ideal for homes that tend to be too humid in the winter.
• ERV (Energy Recovery Ventilation): Transfers both heat and moisture. In the winter, it retains beneficial indoor humidity so your air doesn’t get too dry. In the summer, it prevents humid outdoor air from making your home feel muggy. Ideal for balanced climates or homes that struggle with dry winter air.

Not sure which one you need? Our experts will evaluate your home’s size, insulation, and humidity levels to recommend the perfect system.

• Continuous Fresh Air: Enjoy a constant supply of filtered, oxygen-rich outdoor air, reducing stuffiness and improving overall health and comfort.
• Superior Energy Efficiency: Recover up to 80-90% of the heating or cooling energy that would otherwise be lost through traditional ventilation, keeping your utility bills low.
• Optimal Humidity Control: Prevent winter condensation on windows and inhibit mold and mildew growth by maintaining balanced indoor humidity levels.
• Removes Allergens & Pollutants: Actively exhausts indoor pollutants, pet dander, cooking odors, and VOCs, replacing them with fresh, filtered air.
• Protects Your Home’s Structure: By managing moisture and preventing condensation in walls and attics, you protect your home from long-term water damage and rot.
• Quiet Operation: Modern HRV/ERV units are designed to run whisper-quiet, providing seamless background ventilation without disrupting your daily life.

Custom System Design & Installation

Every home is unique. We calculate your home’s required air exchange rate (CFM) and design a customized ducting layout that integrates seamlessly with your existing HVAC system or operates as a standalone solution.

Retrofitting & Upgrades

Already have an older, inefficient ventilation system? We can upgrade your existing setup with a high-efficiency, modern HRV or ERV unit to maximize performance and energy savings.
