duct cleaning 2Bring the outdoors indoors with our TrueFRESH™ Ventilation Systems. It brings fresh air into your house, even if all the windows are closed. It works to recover heat or cooling from the air leaving the house in any season. What about humidity? TrueFRESH also has energy recovery ventilators (ERVs) that kick into gear on humid days, reducing the amount of humidity coming in.

The TrueFRESH® 150 CFM Energy Recovery Ventilator provides fresher replacement air while recovering up to 70 percent of the exhausted air’s sensible heat, as well as some of the latent heat, by transferring moisture from one air stream to the other. The system draws outdoor air through the ventilator for distribution throughout the house, while stale air is exhausted outside.


  • Balanced ventilation with sensible and latent heat recovery
  • Exchange surface: 104 square feet
  • Intuitive balancing via two variable speed motors and an integrated speed control
  • Washable ERV core
  • Tested for cold weather (down to 5°F/-15°C)

The TrueFRESH® Heat Recovery Ventilator has a streamlined design and simplified balancing, so there’s no need for overhead ducting. The ventilator uses the heat in the stale exhaust air to preheat incoming fresher air, making it great for extreme cold weather.


  • Intuitive balancing via two variable speed motors and an integrated speed control
  • Great for extreme cold weather
  • Automatic defrost
  • 2 operating modes (Intermittent and Continuous Ventilation)

The Benefits of Installing an HRV or ERV System

Modern homes are built to be energy-efficient, but this often results in reduced air exchange, leading to stale indoor air. This is where Heat Recovery Ventilators (HRV) and Energy Recovery Ventilators (ERV) come into play. Both systems enhance indoor air quality and overall home comfort, making them crucial for maintaining a healthy living environment. Midwest Mechanical specializes in integrating these systems into your home’s existing HVAC infrastructure, ensuring optimal performance and energy efficiency.

Improved Air Quality

HRVs and ERVs continuously replace stale indoor air with fresh outdoor air, reducing pollutants, allergens, and odors in your home. This is particularly beneficial for individuals with allergies or respiratory issues, as it ensures a constant supply of clean air.

Energy Efficiency

Preconditioning the incoming air reduces the load on your heating and cooling system. HRVs and ERVs recover energy from the exhaust air and use it to temper the incoming fresh air, cutting down on energy costs.

Moisture Control

ERVs also manage the humidity levels in your home. They can transfer moisture from the incoming humid air to the dry outgoing air during winter and vice versa in summer, helping to maintain comfortable humidity levels year-round.

Comparing HRVs and ERVs: Which is Right for Your Home?

Choosing between an HRV and an ERV depends largely on your climate and specific home needs. Midwest Mechanical provides a tailored approach to help you determine the best option for your situation, emphasizing the differences between the two systems and their respective benefits.

HRVs: Best for Cold Climates

HRVs are ideal for colder regions where heating is predominant. These systems focus on heat recovery, making them efficient for homes in colder climates by retaining heat during the winter months.

ERVs: Ideal for Varied Climates

ERVs are suited for areas with significant seasonal temperature variations. They not only recover heat but also manage humidity levels, making them perfect for regions with hot summers and cold winters.

Considerations for Choosing

  • Local Climate: The effectiveness of HRV and ERV systems can vary depending on local weather patterns.
  • Home Size and Layout: Different systems may be more suitable depending on the size and configuration of your home.
  • Existing HVAC Systems: Compatibility with your current heating and cooling systems is crucial for maximizing efficiency.

Maintenance Tips for HRV and ERV Systems

Regular maintenance is key to ensuring your HRV or ERV system operates efficiently and lasts for years. Midwest Mechanical offers comprehensive service plans that include regular check-ups and cleaning, but there are also steps you can take to maintain your system.

Regular Filter Replacement

Changing the filters in your HRV or ERV system is crucial for maintaining air flow and quality. Filters should be checked every three months and replaced as needed to ensure optimal performance.

Seasonal Inspections

Bi-annual inspections can help catch issues before they become major problems. These checks are best performed in the spring and fall to prepare the system for the heavy workload expected during summer and winter.

Clean Recovery Cores and Vents

The recovery core and vents can accumulate dust and debris, which can impede airflow and efficiency. Annual cleaning of these components is recommended to maintain system effectiveness.
