Is Your ERV System Failing? Here's How We Can Fix It

An Energy Recovery Ventilator is the lungs of your home, exchanging stale indoor air for fresh outdoor air while transferring heat and moisture to maximize efficiency. When this system begins to fail, the consequences are immediate and often uncomfortable. You might notice that your home feels stuffy despite the air conditioner running, or that cooking and pet odors linger significantly longer than usual.

Mechanical failure in an ERV often stems from a compromised heat exchanger core or failing blower motors. Over time, the core can become clogged with debris or suffer from cross-contamination, where the exhaust air mixes with the fresh supply air. This defeats the purpose of the unit. Furthermore, if the fans are no longer operating at the correct RPM, the pressure balance in your home shifts. Positive pressure forces moist air into wall cavities, potentially causing structural damage, while negative pressure draws in unconditioned outdoor air through cracks and crevices.

We address these issues by physically inspecting the core, testing airflows, and evaluating the control board logic. If the unit is beyond the point where a simple repair makes financial sense, we move directly to a replacement plan. Our goal is to remove the defective hardware and integrate a new unit that communicates seamlessly with your existing furnace or air handler.

What You Get Today: Fast Replacement and System Reliability

When you choose to replace your ERV, you are investing in immediate improvements to your living environment. The primary deliverable is a restored balance of air exchange. Modern ERV units are significantly more efficient than models manufactured just a decade ago. They feature higher sensible and latent recovery efficiencies, meaning they are better at keeping heat out in the summer and moisture out of your home.

Your replacement service includes a comprehensive evaluation of your current ductwork connection. Simply swapping a box is rarely enough; we ensure that the collars and flexible duct connections are sealed tight to prevent air leakage in the attic or mechanical room. We also verify that the exterior intake and exhaust hoods are clear of obstructions like bird nests or vegetation, which frequently shorten the lifespan of ventilation equipment.

We provide a turnkey solution that includes:

• Proper Sizing Calculation: We verify that the CFM (Cubic Feet per Minute) capacity of the new unit matches the square footage and occupancy of your home.
• System Integration: We wire the new ERV into your central HVAC thermostat or install a dedicated control for precise management.
• Moisture Control: We configure the system specifically to handle the latent heat (humidity) prevalent in Kentucky summers.
• Filtration Upgrade: New units come with clean, high-grade filters that capture pollen and dust before it enters your home.

How Our Replacement Process Works: A Seamless Transition

Replacing a ventilation system requires a methodical approach to ensure the new unit functions correctly within the existing infrastructure of your home. We do not use guesswork; we follow a strict protocol to ensure safety and efficiency.

• Site Assessment and Selection: First, we evaluate the location of your current unit. Whether it is suspended in a crawlspace, tucked in an attic, or mounted in a utility closet, we determine the accessibility and the physical dimensions required for the new equipment. We then select a model that aligns with your specific airflow requirements.
• Safe Removal and Disposal: Next, we disconnect the high-voltage electrical lines and low-voltage control wires. We carefully detach the ductwork to avoid damaging the vapor barriers. The old unit is removed from the property and disposed of according to environmental regulations, ensuring no hazardous materials are left behind.
• Installation and Sealing: Then, the new ERV is mounted. We use vibration-isolation hangers or pads to ensure the unit runs quietly. We reconnect the ductwork, often replacing the immediate connection points to ensure an airtight seal. Aluminum tape and mastic are applied to prevent any air leakage.
• Electrical and Drainage Connection: After mounting, we reconnect the power and control wiring. Since ERVs manage moisture, we also ensure the condensate line is properly trapped and routed to a drain. This step is critical to prevent water damage in your home.
• Balancing and Calibration: Finally, we balance the airflow. An ERV must bring in exactly as much air as it exhausts. We use manometers and flow hoods to measure the pressure and adjust the dampers accordingly. This ensures your home remains neutral, preventing drafts and maximizing energy recovery.

When Replacement Beats Repair: Making the Smart Choice

Homeowners often struggle with the decision to repair an aging unit or invest in a full replacement — browse our FAQs for help. While a simple capacitor failure or a broken belt is worth fixing, core failures in an ERV usually dictate a replacement. The heat exchange core is the most expensive component; if it is cracked, moldy, or damaged, the cost of the part and labor often approaches the price of a brand-new unit with a fresh warranty.

Age is a primary factor. If your equipment is over 10 to 12 years old, parts availability becomes an issue. Manufacturers frequently update their chassis designs, making older motors and control boards obsolete. Investing money into a legacy system often results in diminishing returns.

Consider replacement if you experience the following:

• Core Failure: If the energy transfer core is delaminating or blocked, efficiency drops to near zero.
• Motor Noise: Grinding or screeching bearings in the blower motors indicate imminent failure. Replacing two motors and a control board is rarely cost-effective compared to a new unit.
• Mold Presence: If moisture has accumulated inside the unit due to poor drainage or insulation failure, cleaning is often impossible. Replacement is the only sanitary option.
• Energy Efficiency: Newer models utilize ECM (Electronically Commutated Motors) which use a fraction of the electricity compared to older permanent split capacitor motors.

Local Notes: Adhering to Auburn's Codes and Climate Needs

Auburn experiences a specific climate profile that dictates how ventilation must be handled. We deal with hot, humid summers and significant rainfall, particularly in the spring. This environment makes an ERV superior to an HRV (Heat Recovery Ventilator) for most local homes. While an HRV only transfers heat, an ERV transfers both heat and moisture.

In our service area, controlling indoor humidity is just as important as controlling temperature. During the summer, an ERV rejects the humidity from the incoming outdoor air, sending it back outside. This prevents your air conditioner from being overwhelmed by moisture, allowing it to cool your home more efficiently. Without this moisture transfer, your home could feel clammy, and your AC would run constantly to dehumidify the space.

Technicians at Carter Heating and Cooling understand that local building codes regarding ventilation rates are designed to ensure occupant health. We adhere strictly to these standards, ensuring that the fresh air intake is positioned far enough away from exhaust vents, gas flues, and driveway areas to prevent the intake of carbon monoxide or fumes. We also ensure that all condensate drains are plumbed according to local plumbing regulations to handle the condensation generated during humid months.

Comparing Modern ERV Features and Efficiency Ratings

The technology inside ventilation systems has advanced rapidly. When we replace your unit, we look at several key performance indicators. The "Sensible Recovery Efficiency" (SRE) measures how well the unit transfers heat, while the "Latent Recovery" measures moisture transfer. We select units that have high ratings in both categories to suit the Kentucky climate.

Modern units also offer variable speed operation. Older units often had one or two speeds—on or off. New systems can ramp up or down based on real-time needs. For example, if you are hosting a party with many guests, the system can increase the air exchange rate to keep the air fresh. Conversely, when the house is empty, it can run at a low trickle to maintain air quality without wasting energy.

• MERV Filtration: We look for units that support higher MERV-rated filters to trap smaller particulates.
• Frost Control: Even with mild winters, frost can form on the core. Modern units have intelligent defrost cycles that recirculate warm indoor air to melt frost without creating negative pressure.
• Smart Controls: Compatibility with smart thermostats allows you to monitor your indoor air quality and control ventilation from your phone.
