Does an ERV replace my heating or cooling system?

No. An ERV works alongside compatible heating and cooling equipment. It is designed to provide controlled ventilation, not replace the property's primary HVAC system.

Can an ERV help with indoor humidity?

An ERV can transfer some moisture between incoming and outgoing air streams, but performance depends on the equipment, installation, season, building conditions, and local climate.

Does an ERV bring outdoor pollutants inside?

ERV systems normally filter incoming air, but filter performance depends on the equipment and filter selected. Filters require inspection and replacement according to manufacturer recommendations.

Can an ERV be added to an existing home?

In many cases, yes. The installation requirements depend on available space, ductwork, HVAC configuration, building layout, and ventilation needs.

How do I know which ERV size I need?

The system should be selected using the property's size, occupancy, layout, airflow requirements, existing HVAC equipment, and applicable ventilation standards.

Does an ERV require maintenance?

Yes. Filters, the recovery core, fans, exterior vents, controls, and airflow should be inspected and maintained according to the manufacturer's instructions.

Do you provide ERV repair and maintenance?

Yes, ChillTech Corporation provides ERV installation, inspection, troubleshooting, repair, filter service, cleaning, and preventive maintenance for supported systems.

What Is Energy Recovery Ventilation?

An Energy Recovery Ventilator, commonly called an ERV, is a whole-home ventilation system that exchanges stale indoor air with fresh outdoor air. During this process, the system transfers heat and moisture between the outgoing and incoming air streams, helping reduce the energy required to heat or cool incoming air.

The result is controlled, balanced ventilation that keeps your home supplied with fresh air without simply throwing away the energy you have already spent heating or cooling your indoor air.

Benefits of Energy Recovery Ventilation

A well-installed ERV improves comfort and air quality while helping your HVAC system work more efficiently.

Continuous supply of fresh outdoor air

Removal of stale indoor air

Reduced indoor odors

Better control of indoor humidity

Reduced buildup of airborne contaminants

Improved indoor air quality

Lower ventilation-related energy loss

More balanced airflow throughout the property

Reduced strain on heating and cooling equipment

Greater year-round indoor comfort

Signs Your Property May Need an ERV

If you notice several of these, controlled ventilation may make a real difference.

Rooms frequently feel stuffy
Persistent indoor odors
Excess indoor humidity
Condensation on windows
Limited natural ventilation
Recently completed air-sealing or insulation work
A tightly constructed modern home
Uneven airflow between rooms
Indoor air feels stale during winter or summer
You want better ventilation without wasting conditioned air

How an ERV Works

Fresh air in, stale air out — with heat and moisture recovered in between.

Stale indoor air is pulled from the property.
Fresh outdoor air enters through a separate airflow path.
The two air streams pass through an energy-recovery core without directly mixing.
Heat and moisture are transferred between the air streams.
Filtered fresh air is distributed throughout the property.
Stale air is exhausted outdoors.

ERV Maintenance

Routine care keeps your system efficient and your air fresh.

Inspecting and replacing filters

Cleaning the energy-recovery core

Inspecting exterior intake and exhaust vents

Checking drainage components when applicable

Verifying fan operation

Inspecting duct connections

Testing controls

Confirming balanced airflow

Maintenance frequency depends on your equipment, usage, environmental conditions, and the manufacturer's recommendations — there is no single interval that fits every system. We'll help you set a schedule that matches your equipment and home.

How an ERV Compares

ERV vs. Standard Exhaust Fans

Bathroom and kitchen exhaust fans remove indoor air but do not normally recover energy from that outgoing air. An ERV provides controlled, balanced ventilation while transferring part of the heat and moisture between the incoming and outgoing air streams.

ERV vs. HRV

An ERV transfers heat and a portion of the moisture.
An HRV primarily transfers heat.
The right choice depends on the building, HVAC system, climate, humidity, and your needs.

ChillTech Corporation evaluates your property before recommending equipment, so you get the system that actually fits your home — not a one-size-fits-all answer.
