What You Get With Professional HRV Service

Restoring the air balance in your home requires more than a simple filter change. Our service approach focuses on the mechanical and aerodynamic integrity of your ventilation system. When you request service, you receive a thorough examination of the heat exchange core, the blower motors, and the ductwork integration. The goal is to ensure that the volume of stale air leaving the home matches the volume of fresh air entering, neutralizing negative pressure issues.

Diagnostic Precision and Repair Scope

The primary objective during a service call is to identify the root cause of airflow restriction or mechanical failure. Technicians utilize specialized tools, such as manometers and magnehelic gauges, to measure the static pressure within the system. This data reveals whether the blockage lies within the core, the intake hoods, or the distribution grilles.

1. Motor and Fan Assembly Inspection: Technicians test the amperage draw on both the supply and exhaust motors. High amperage often signals bearing failure or dust accumulation, while zero amperage indicates electrical faults or capacitor failure.
2. Heat Exchange Core Cleaning: The core is the heart of the system. Over time, it accumulates particulate matter that acts as an insulator, reducing heat transfer efficiency. Services include deep cleaning of the core to restore thermal conductivity.
3. Condensate Drain Management: HRVs remove moisture from the outgoing air. If the condensate line is clogged, water can back up into the unit or leak into your ceiling. Clearing and priming the drain trap is a standard part of the service.
4. Control and Sensor Calibration: Modern HRVs rely on humidistats and timers. We verify that wall controls are communicating correctly with the main unit and that defrost cycles trigger appropriately during freezing weather.

Full System Balancing

An unbalanced HRV creates pressure imbalances in the home. If the unit exhausts more air than it brings in, it creates negative pressure, drawing in soil gases (like radon) or back-drafting combustion appliances. Conversely, too much intake air can force moisture into wall cavities. Professional service includes a complete system balancing procedure to ensure airflow neutrality.

How the Installation and Replacement Process Works

Installing a new HRV or replacing an aging unit is a calculated process designed to integrate seamlessly with your existing HVAC infrastructure. The process begins with a load calculation to determine the necessary Cubic Feet per Minute (CFM) exchange rate required for your specific square footage and occupancy levels. In Franklin, where seasonal shifts are distinct, sizing the unit correctly is vital to prevent over-ventilation in winter (which dries out the air) or under-ventilation in summer.

Site Assessment and Duct Design

Before any equipment is placed, the technician maps out the ducting strategy. For dedicated systems, new ductwork is run to bathrooms and kitchens to pull stale air directly from the source. For simplified systems, the HRV is tied into the existing furnace return duct. The assessment determines the most efficient route to minimize static pressure and maximize airflow.

1. Unit Selection: Based on the assessment, we select a unit with the appropriate Sensible Recovery Efficiency (SRE) rating. High SRE ratings indicate better heat transfer, leading to lower utility bills.
2. Mounting and Vibration Isolation: The unit is suspended or wall-mounted using vibration-dampening hardware. This step is crucial for minimizing noise transfer through the framing of the house.
3. Duct Connection: Insulated flex duct or rigid metal ducting is connected to the ports. All joints are sealed with mastic or foil tape to prevent air leakage. Intake and exhaust hoods are installed on the exterior of the home, spaced according to code to prevent cross-contamination of airstreams.

Electrical and Control Integration

The electrical phase involves wiring the unit to a dedicated circuit and connecting the low-voltage controls. We install main wall controls in a central location and optional timers in high-humidity areas like bathrooms. If the HRV is interlocked with a forced-air furnace, we wire the systems to ensure the furnace blower activates whenever the HRV is running, distributing fresh air evenly throughout the house.

Commissioning and Verification

The final step is the most technical. The installer uses a flow hood or flow grid to measure the actual airflow at the grilles. Balancing dampers are adjusted until the intake and exhaust streams are perfectly matched. The homeowner is then walked through the operation of the wall controls and maintenance requirements, such as filter cleaning schedules.

When Replacement Beats Repair

Deciding between repairing an existing HRV and investing in a new system depends on the age of the unit, the severity of the failure, and the availability of parts. While many mechanical issues are fixable, there are specific scenarios where replacement offers a better return on investment and superior air quality.

Critical Component Failure

If the heat recovery core is damaged, replacement is often the only viable option. The core separates the stale exhaust air from the fresh intake air. If the core material cracks or degrades, cross-contamination occurs, meaning the system effectively recirculates indoor pollutants. Replacing a core can be nearly as expensive as a new unit, especially for older models where parts are scarce.

Motor Burnout in Older Units

HRV motors work hard, often running 24/7. If a motor fails in a unit that is over 10 to 12 years old, replacing the motor acts as a temporary patch. Often, the control board or the second motor is near the end of its life as well. Investing in a new system provides new warranties and resets the clock on mechanical reliability.

Efficiency Upgrades

Older HRVs utilized AC (Alternating Current) motors, which consume significant electricity. Modern units feature ECM (Electronically Commutated Motors) that operate at a fraction of the energy cost and offer variable speed capabilities. If your current system is noisy and drives up your electric bill, upgrading to an ECM-driven model pays for itself over time through energy savings.

1. Obsolescence: If the manufacturer has discontinued the model, sourcing control boards or specific sensors becomes difficult and expensive.
2. Noise Levels: Older units tend to vibrate and hum loudly. New models are designed with sound-dampening technology for silent operation.
3. Filtration compatibility: Newer systems often support higher MERV-rated filters, allowing for better capture of pollen and allergens, which is essential for allergy sufferers.

Local Considerations for Ventilation

Operating an HRV in Franklin requires specific attention to the local climate and regulatory environment. The region experiences a mix of humid summers and cold winters, which dictates how ventilation systems must be configured and maintained.

Managing Humidity and Seasonality

In the winter, the primary function of the HRV is to retain heat while expelling moisture generated by cooking and showering. This prevents condensation on windows and mold growth in attics. However, during the humid summer months, improper settings can bring in too much moisture. Local service protocols often involve adjusting the operational settings seasonally. Technicians may recommend changing the ventilation strategy or interlocking the system with a dehumidifier to handle the heavy latent load typical of Kentucky summers.

Permit and Code Compliance

Ventilation work is subject to local building codes and state regulations. Kentucky adheres to specific standards regarding air exchange rates, typically aligned with ASHRAE 62.2. These codes mandate a specific amount of fresh air based on the floor area and number of bedrooms. Professional service ensures that any modification or replacement meets these legal requirements, which is critical for maintaining home value and insurance compliance.

Utility Integration

Many homes in the area utilize natural gas or heat pumps. The HRV must be balanced so it does not interfere with the draft of gas appliances. Back-drafting is a serious safety hazard where combustion gases are pulled back into the living space due to negative pressure. Our technicians verify that the ventilation system operates safely alongside your heating equipment.
