We bring the necessary tools and common replacement parts to the job site, minimizing downtime and restoring the balance of your indoor climate as fast as possible.

Comprehensive Scope of ERV Services

An ERV system is more complex than a standard exhaust fan. It involves a heat exchanger, fans, and filters that must work in perfect synchronization with your central heating and cooling system. Our service protocol covers every mechanical and electrical component of the unit to ensure it performs under the specific demands of the local climate.

Core Inspection and Cleaning

The enthalpy core is the heart of the ERV, where heat and moisture transfer occur. Over time, this core can become clogged with dust, pollen, and particulates.

1. We remove the core for a deep inspection.
2. Technicians vacuum and wash the core according to manufacturer specifications to prevent mold growth.
3. We inspect the integrity of the core material to ensure no cross-contamination between exhaust air and fresh air streams.

Airflow Balancing and Calibration

If an ERV is not balanced, it may pressurize or depressurize your home, leading to drafts or moisture intrusion in wall cavities.

1. We use professional manometers to measure airflow in the supply and exhaust streams.
2. Dampers are adjusted to ensure equal intake and output.
3. Technicians verify that the unit is not fighting against your furnace or air conditioner.

Filter Maintenance and Upgrades

Standard filters protect the core, but they can restrict airflow if neglected.

1. We replace or clean pre-filters and main filters.
2. Our team assesses if higher MERV-rated filters are compatible with your specific unit to capture smaller allergens without straining the motor.

Motor and Fan Diagnostics

The fans in an ERV run frequently.

1. We lubricate motor bearings if applicable.
2. Technicians check amperage draw to detect early signs of motor failure.
3. Fan blades are cleaned to reduce noise and vibration.

Control System Integration

1. We verify that wall controls, timers, and dehumidistats are communicating correctly with the main unit.
2. Wiring connections are tightened to prevent intermittent operation issues.

How the Installation and Replacement Process Works

Installing or replacing an ERV is a precise construction task that integrates seamlessly with your existing ductwork. We follow a rigorous, step-by-step process to ensure the system delivers maximum efficiency from day one.

1. Load Calculation and Unit Sizing: First, we determine the cubic feet per minute (CFM) of airflow required based on the square footage of your property and the number of occupants. Undersized units fail to remove pollutants; oversized units waste energy. We calculate the exact requirements to ensure optimal air exchange rates.
2. Ductwork Design and Modification: Next, we plan the connection points. For dedicated systems, we map out independent duct runs to bathrooms and kitchens. For integrated systems, we identify the best return and supply plenums on your furnace to tap into. This step involves cutting and sealing metal to prevent air leakage.
3. Mounting and Vibration Isolation: Technicians mount the ERV unit using vibration-dampening chains or brackets. This prevents the mechanical hum of the fans from transferring into the framing of the house, ensuring silent operation.
4. Venting to the Exterior: We cut two penetrations in the exterior wall—one for fresh air intake and one for stale air exhaust. These are spaced a specific distance apart to prevent short-circuiting, where exhaust air is immediately sucked back into the intake. We install weather-proof hoods with screens to keep pests and debris out.
5. Electrical and Drainage Connection: Hardwiring the unit to the electrical panel and connecting low-voltage controls happens next. Since ERVs manage moisture, we also install a condensate line if the specific model requires it, routing it to a floor drain or condensate pump.
6. System Balancing: Finally, we perform the critical balancing act. Using flow measuring stations, we adjust the dampers until the intake air equals the exhaust air. This prevents the house from becoming positively or negatively pressurized.

When to Replace vs. Repair Your ERV

Homeowners often struggle to decide whether to invest in repairs or opt for a full system replacement. Check our FAQs for help. Making the right financial decision depends on the age of the unit, the cost of the repair, and the efficiency gains of modern technology.

When to Repair

1. Unit is under 7 years old: Most ERVs have a lifespan of 15-20 years. If the unit is relatively new, repair is usually the most cost-effective path.
2. Simple Component Failure: If the issue is a failed sensor, a broken belt, or a single fan motor, these parts are replaceable and significantly cheaper than a new unit.
3. Clogged Filters or Core: If performance issues are due to lack of maintenance, a professional cleaning and filter change often restores full functionality.
4. Loose Ductwork: Air leaks usually require sealing rather than unit replacement.

When to Replace

1. Core Failure: If the enthalpy core is damaged, cracked, or heavily impacted by mold that cannot be cleaned, the cost of a replacement core often rivals the cost of a new, more efficient unit.
2. Motor Failure in Older Units: If a blower motor fails in a unit older than 12 years, investing in a repair is often throwing money at a dying system.
3. Obsolete Parts: If the manufacturer has discontinued support for your specific model, finding parts may be impossible or prohibitively expensive.
4. Inefficiency and Noise: Modern ERVs are significantly quieter and recover more energy than models from a decade ago. If the current unit is loud and energy bills are rising, replacement offers a better ROI.

Local Considerations for Ventilation Systems

Operating an ERV in this region requires specific knowledge of the humid subtropical climate. Unlike Heat Recovery Ventilators (HRVs), which only transfer heat, ERVs transfer both heat and moisture. This distinction is critical for Bowling Green residents. During our hot, humid summers, an ERV rejects the humidity from the incoming fresh air, sending it back outside. This helps keep the indoor air dry and reduces the load on your air conditioner. An HRV, by contrast, would bring that humidity inside, making your home feel clammy and forcing your AC to work harder.

Permits and Regulations

Local building codes dictate ventilation standards to ensure occupant safety.

1. We manage all necessary permitting processes required for new installations or major modifications to ventilation systems.
2. Compliance with ASHRAE 62.2 standards (Ventilation and Acceptable Indoor Air Quality in Residential Buildings) is strictly followed.
3. Electrical connections adhere to local safety codes, ensuring that high-voltage wiring is handled by qualified professionals.

Seasonal Maintenance Timing

The best time to service your ERV is during the shoulder seasons—spring and autumn.

1. Servicing before summer ensures the core is clean and ready to handle high humidity loads.
2. Servicing before winter ensures the heat exchange efficiency is maximized to retain warmth during the colder months.
3. Neglecting this timing can lead to reduced efficiency exactly when you need the system most.

Why Technical Expertise Matters

In the world of HVAC, ventilation is often treated as an afterthought by generalist contractors. However, incorrect installation of an ERV can lead to serious building envelope issues, including condensation inside walls and back-drafting of combustion appliances. You need a partner who understands building science, not just someone who can hang a box and connect a duct.

• Precision Diagnostics: We do not guess. If your windows have condensation, we investigate the humidity levels and ventilation rates. If you smell cooking odors in the bedroom, we check the pressure balance of the system. Carter Heating and Cooling technicians use advanced diagnostic tools to visualize airflow and identify the root cause of the problem.
• Inventory and Availability: Delaying a repair because of ordered parts leaves you with poor air quality. We maintain a robust inventory of common ERV components, including motors, control boards, and filters. This logistical preparation allows us to resolve most issues on the first visit.
• The "Whole Home" Approach: We view your ERV as part of a larger ecosystem. It interacts with your furnace, your air conditioner, your bathroom fans, and your range hood. Our service accounts for these variables. We ensure that your ERV enhances your existing HVAC investment rather than conflicting with it.
• Clear Communication and Pricing: You will receive a detailed explanation of the work required before we begin. We explain the "why" behind every repair or replacement recommendation. There are no hidden fees or surprise charges. You get the facts, the technical data, and a clear path to resolution.
