10 Common Mistakes in HRV System Installation (And How to Avoid Them)
Installing a Heat Recovery Ventilation (HRV) system can significantly improve your indoor air quality, energy efficiency, and overall comfort. However, improper installation can lead to poor performance, higher energy bills, and even system failure. At Belcarra Mechanical, we often get calls to fix HRV systems that were incorrectly installed.
To help you avoid these issues, here are 10 common
mistakes made during HRV installation—and how to prevent them.
1. Incorrect Sizing of the HRV System
Installing a unit that’s too small or too large for the space will result in poor ventilation and inefficiency.
Tip: Always calculate the ventilation needs based on your home’s square footage and layout.
2. Poor Placement of Intake and Exhaust Vents
Placing vents too close together or near contaminants like vehicle exhaust can cause air contamination.
Tip: Intake vents should be placed far from exhaust vents and pollutants for clean air intake.
3. Improper Ductwork Installation
Using long, twisted, or poorly sealed ductwork can reduce airflow and system performance.
Tip: Keep ducts straight, properly sealed, and insulated to minimize heat loss and resistance.
4. Lack of Proper Balancing
Many installations skip airflow balancing, which results in uneven ventilation and pressure issues.
Tip: Use a flow hood or balancing kit to ensure proper airflow in and out of each space.
5. Skipping the Pre-Filter and Cleaning Access
Some installers don’t provide easy access to filters, making regular maintenance difficult.
Tip: Ensure filters are easy to access, clean, or replace to maintain system performance.
6. Wrong Connection to Existing HVAC
Connecting the HRV incorrectly to the HVAC system can interfere with heating/cooling performance.
Tip: Follow manufacturer guidelines or hire a certified technician to handle integration properly.
7. No Consideration for Noise Control
HRV systems can be noisy if not installed with sound-dampening in mind.
Tip: Use insulated ducts or vibration isolators to minimize noise in living areas.
8. Ignoring Local Building Codes
Overlooking ventilation requirements or electrical codes can lead to fines or unsafe setups.
Tip: Always check local codes or hire a professional familiar with local regulations.
9. Poor Drainage Setup for Condensation
Improper drainage can lead to water damage or mold growth.
Tip: Make sure condensate drain lines are properly sloped and connected.
10. DIY Installation Without Experience
Installing an HRV system without proper knowledge can cause long-term problems.
Tip: Save time and money by hiring qualified HVAC technicians with HRV experience.
