Comprehensive ERV Service Breakdown

An Energy Recovery Ventilator is a complex piece of equipment that manages both heat and moisture transfer. When you book a service with us, you are not simply getting a filter change; you are receiving a holistic restoration of the system’s thermodynamic capabilities. Our service is designed to tackle the specific challenges of the humid subtropical climate found in this region.

Core Inspection and Cleaning

The heart of your ERV is the energy exchange core, often made of a permeable membrane or desiccant material. Over time, this core can become clogged with particulate matter, grease, or pollutants.

1. Technicians carefully remove the core to inspect for delamination, mold growth, or structural collapse.
2. We utilize specialized vacuuming and cleaning techniques suited to the specific material of your core (whether polymer or fiber-based) to ensure airflow channels are unobstructed.
3. A compromised core is often the primary reason for poor humidity control; cleaning it restores the latent heat transfer efficiency necessary for keeping summer humidity outdoors.

Blower Motor and Fan Maintenance

Your ERV relies on two distinct fans: one to exhaust stale air and one to intake fresh air. If these fans fall out of sync, your home becomes pressurized or depressurized.

1. We inspect blower wheels for dust buildup, which can cause imbalance and noisy operation.
2. Motor bearings are lubricated where applicable to prevent overheating and seizure.
3. Capacitors and electrical connections are tested to ensure the motors are receiving the correct voltage and amperage, preventing premature burnout.

Filter Management and Airflow Pathways

Standard filters protect the core, but they can easily become impacted, choking the system.

1. We replace or wash pre-filters according to manufacturer specifications.
2. Our team inspects the intake and exhaust hoods on the exterior of your home. These are often entry points for pests, leaves, or debris that restrict CFM (Cubic Feet per Minute) flow.
3. We ensure the insect screens are clear and that the dampers operate freely to prevent back-drafting when the system is off.

Condensate Drain Line Clearing

Although ERVs manage moisture, they can produce condensate under certain extreme conditions or if not pitched correctly.

1. We flush the condensate line to prevent algae buildup and water damage.
2. Technicians verify the P-trap is primed effectively to stop sewer gases or outdoor odors from being drawn back into the ventilation stream.

Step-by-Step ERV Servicing Process

Our approach to servicing your ventilation system is methodical and data-driven. We do not guess at airflow rates; we measure them. This ensures that your system complies with ASHRAE standards for residential ventilation.

Initial System Run-Through

The process begins with a functional test. We cycle the unit through its various modes (low speed, high speed, and recirculation if equipped) to listen for mechanical anomalies like grinding bearings or rattling sheet metal.

Static Pressure Measurement

Using a manometer, we measure the static pressure across the core and the filters. High static pressure indicates a blockage in the ductwork or a fouled core. This data point tells us exactly how hard the fans are working to move air.

Electrical Safety Check

We inspect the control board and low-voltage wiring that connects the ERV to your main thermostat or humidistat. Loose connections can cause intermittent operation or phantom startups. We tighten all terminals and check the transformer voltage.

Cleaning and Component Care

Once the diagnostics are complete, we proceed with the physical cleaning of the cabinet, fans, and core. We wipe down the interior insulation to remove any mold spores or dust that could be reintroduced into the supply air.

Airflow Balancing

This is the most critical step. An unbalanced ERV can push warm, moist air into wall cavities (positive pressure) or suck radon and soil gases from the crawlspace (negative pressure).

1. We use a magnehelic gauge or flow station to measure the intake and exhaust streams.
2. Technicians adjust the dampers on the duct runs or the potentiometers on the circuit board to equalize the airflow.
3. The goal is to achieve "neutral pressure" or slightly positive pressure depending on the specific building envelope requirements of your home in Scottsville.

Control Calibration

We verify that the wall controls are reading humidity levels accurately. If your humidistat calls for ventilation when the outdoor air is saturated with moisture, we adjust the lockout settings to prevent the ERV from bringing in more humidity than it can reject.

Deciding Between ERV Repair or Replacement

Homeowners often face the dilemma of whether to invest in repairs for an aging unit or to upgrade to a modern, more efficient model. Making the right decision depends on the severity of the failure and the age of the equipment.

When to Repair

1. The unit is under 7 years old: Most ERVs have a lifespan of 15 to 20 years. If the unit is relatively new, repair is usually the most cost-effective option.
2. Isolated Component Failure: If the issue is a single part, such as a burnt-out fan motor, a faulty control board, or a snapped belt, these are standard repairs.
3. Core is Intact: As long as the energy exchange core is not physically damaged or mold-infested, the system is worth saving. The core is the most expensive component; if it is healthy, the rest of the unit is serviceable.

When to Replace

1. Core Failure: If the enthalpy core has crumbled, delaminated, or is heavily infested with mold that cannot be cleaned, replacement is often necessary. The cost of a replacement core can sometimes approach the cost of a new unit.
2. Obsolete Technology: Older units often use AC motors that consume significant electricity. Modern units utilize ECM (Electronically Commutated Motors) which are variable speed and use a fraction of the power. If your current unit is noisy and energy-hungry, an upgrade pays for itself over time.
3. Improper Sizing: If your home has undergone renovations, additions, or significant air sealing, the original ERV may no longer be sized correctly. A unit that is too small cannot provide adequate ventilation, while one that is too large will cycle rapidly and wear out. In these cases, replacement with a properly sized unit is required.

Understanding Local ERV Regulations and Seasonal Tips

Operating an ERV in this region requires specific knowledge of the local climate and building codes. The weather patterns here dictate how your system should be configured for maximum protection against moisture damage.

Managing High Humidity

In our humid subtropical climate, the summer months bring heavy moisture loads. Standard ventilation (opening a window) introduces this humidity directly into the home. An ERV is essential because it transfers moisture from the incoming fresh air to the outgoing stale air, keeping the interior drier. However, during days of extreme saturation, we recommend adjusting the settings to limit intake or ensure the air conditioner is running in tandem to handle the residual load.

Winter Operation and Frost Control

While winters are generally mild to cool, temperatures can drop below freezing. When this happens, the moisture in the outgoing warm air can freeze in the core, blocking airflow. We ensure your unit’s defrost mechanism—whether it uses recirculation or an electric pre-heater—is functioning correctly. This prevents ice damage to the core and ensures continuous ventilation even on the coldest nights.

Permits and Code Compliance

Local building codes regarding ventilation are increasingly strict to ensure indoor air quality (IAQ). When we perform major repairs or replacements, we ensure all work complies with local mechanical codes. This includes verifying that intake vents are positioned the correct distance away from exhaust vents, gas flues, and dryer vents to prevent the re-entrainment of hazardous gases.
