What Our HRV Service Includes: Efficiency Assessments and Quick Fixes

When you request service for a Heat Recovery Ventilator, you need more than a simple filter change. Our technicians perform a deep-dive analysis of the entire ventilation loop. The goal is to identify exactly where airflow is being restricted or where heat transfer is failing. This process begins with a complete system audit. We inspect the intake and exhaust hoods on the exterior of your property to ensure they are free from debris, bird nests, or ice buildup, which are common issues in this region.

Once the exterior check is complete, we move to the internal components. The core of the HRV is where the magic happens—transferring heat from stale outgoing air to fresh incoming air. Over time, this core can become clogged with dust and particulate matter. We remove and clean the heat exchange core using manufacturer-approved methods to prevent damage to the delicate fins. We also inspect the condensate drain. A blocked drain can cause water damage to the unit and surrounding areas, as well as lead to bacterial growth within the system itself.

Our service protocol also covers the mechanical and electrical components:

1. Blower Motor Inspection: We check the fans for bearing wear, dust accumulation, and proper RPMs. A dragging motor consumes more electricity and moves less air.
2. Damper Actuator Testing: The dampers control the flow of air for defrost cycles and recirculation. We ensure these open and close fully to prevent cold air dumps during winter.
3. Filter Replacement and Housing Cleaning: We replace dirty filters and sanitize the filter housing to prevent mold spores from re-entering the airstream.
4. Control Logic Verification: We test wall controls, humidistats, and timers to ensure the unit responds correctly to user inputs and humidity levels.

Understanding the HRV Service Process: Step-by-Step

Professional HRV service is a structured process designed to minimize downtime while maximizing system longevity. We do not guess; we test. The process is methodical, ensuring that every variable affecting your indoor air quality is accounted for.

Diagnostic and Electrical Safety Check

The service begins with a safety check. We verify voltage and amperage draws on the motor to ensure they match the manufacturer’s specifications. High amp draws often indicate a failing motor or a significant blockage. We also inspect all wiring connections for signs of corrosion or overheating, which can be fire hazards.

The Cleaning Phase

Cleaning an HRV involves precision. We carefully vacuum the interior cabinet to remove accumulated dust that bypasses the filters. The fan blades are cleaned to ensure they are balanced. Even a small layer of dust on a fan blade can cause wobbling, noise, and premature bearing failure. The heat recovery core is removed and washed (if applicable to the specific model) or vacuumed carefully. We flush the condensate line with water and a cleaning solution to ensure free flow.

System Balancing

This is the most critical step that general handymen often overlook. An HRV must be "balanced," meaning the amount of air coming in equals the amount of air going out.

1. First, we use a magnehelic gauge or a flow measuring station to read the pressure differential in the supply and exhaust air streams.
2. Next, we adjust the dampers on the unit to equalize these airflows.
3. If the system is unbalanced, your home creates positive or negative pressure. Negative pressure can suck dangerous gases (like carbon monoxide from a furnace) back into the home, while positive pressure pushes moist air into wall cavities, causing rot.
4. Finally, we lock the dampers in the correct position and record the final airflow readings for your records.

Performance Verification

After cleaning and balancing, we run the system through all its modes—continuous, high-speed override, and defrost. We verify that the defrost cycle engages when sensors detect freezing temperatures, which is vital during Morgantown winters to prevent the core from icing up solid.

Deciding Between HRV System Repair and Replacement

Homeowners often face the difficult choice of whether to invest in repairs or opt for a full system replacement. Making the right decision depends on the age of the unit, the severity of the failure, and the availability of parts. HRV systems typically last between 15 to 20 years with proper maintenance. However, neglected systems may fail much sooner.

When to Repair

If your unit is under 10 years old and the issue is related to minor components like sensors, capacitors, or a clogged drain line, repair is almost always the most cost-effective solution. Even a failed fan motor can be worth replacing if the heat exchange core is still in excellent condition. If the unit makes noise but still moves air effectively, it likely requires a simple mechanical adjustment or bearing lubrication.

1. Repair is viable if the cost is less than 50% of a new unit.
2. Repair is recommended if the heat exchange core is intact and undamaged.
3. Repair is the right choice if the warranty covers parts or labor.

When to Replace

Replacement becomes necessary when the heart of the system fails. If the heat exchange core is damaged, cracked, or severely corroded, it cannot transfer energy effectively and may allow cross-contamination between stale and fresh air streams. In this scenario, the cost of a replacement core often rivals the cost of a new, more efficient unit.

1. Replace if the unit is over 15 years old and requires a major component like a motor or board. Older motors are significantly less efficient than modern ECM (Electronically Commutated Motor) fans.
2. Replace if you have renovated your home and increased its size or airtightness. The old unit may no longer be sized correctly to handle the volume of air required for proper ventilation.
3. Replace if the unit uses obsolete parts that require weeks to source, leaving you without ventilation.
4. Replace if the system is an older model with low Sensible Recovery Efficiency (SRE). Modern units offer much higher SRE ratings, meaning they save significantly more on heating and cooling bills.

Morgantown Climate Insights: Best Practices for HVAC Maintenance

The climate in Morgantown dictates specific maintenance requirements for Heat Recovery Ventilators. We experience a humid subtropical climate, which brings distinct challenges in both summer and winter. Understanding these local factors helps in maintaining the longevity of your system.

Winter Operations

During our winters, the temperature difference between inside and outside is significant. This is when your HRV works hardest to recover heat. The primary concern during this season is the defrost cycle. If the HRV drain line freezes or the defrost damper fails, the core can turn into a block of ice, stopping airflow completely. We ensure that the condensate drain is properly trapped and insulated if it runs through unconditioned spaces like attics or crawlspaces.

Summer Humidity Management

Summers here are hot and humid. While an HRV is designed primarily for heat recovery, it also plays a role in moisture management. However, running an HRV excessively during high-humidity days can bring too much moisture inside. We help you understand how to set your humidistat and controls to minimize latent load (humidity) on your air conditioning system during July and August. In some cases, checking the seal on the summer bypass damper is necessary to ensure you aren't recovering heat when you are trying to cool the house.

Local Codes and Utilities

Proper ventilation is not just about comfort; it is often a matter of code compliance, especially in newer, tighter construction. We ensure that all service work complies with local building standards regarding ventilation rates. Furthermore, maintaining your HRV helps lower the load on your main heating plant. Local utility providers often recommend regular maintenance to ensure that your primary heating system isn't fighting against cold drafts caused by an unbalanced ventilation system.
