FRESH AIR, YEAR-ROUND

Energy Recovery Ventilator (ERV) Installation

An Energy Recovery Ventilator (ERV) is a whole-house ventilation system that continuously replaces stale indoor air with fresh outdoor air. Inside the unit, the outgoing and incoming airstreams pass each other through an energy recovery core without mixing, so heat and moisture move from one stream to the other. You get a steady supply of fresh air without the comfort and energy penalty of opening a window.

Today’s homes are built tighter to save energy, which also traps cooking odors, humidity, and airborne pollutants inside. An ERV gives that air a controlled way out and brings fresh, filtered air in, working alongside your heating and cooling system all year.

FROM YOUR NEIGHBORS

What Our Homeowners Say.

★★★★★

"My self-contained wine cooling unit died, and I feared it would be a huge task to replace. Cardinal came out and installed a new one in an hour and a half. Extremely friendly, very clean work, and even took the old unit at no extra cost. They went above and beyond in every way, and I couldn't have asked for a better experience."

Jeff W.

★★★★★

"Cardinal HVAC is the absolute best. Don’t waste your time with others. Not only are they very professional and do excellent work, but they’re honest and friendly. Quick example, I had an AC problem and a couple companies came out and said it would be about a $3000 job. Cardinal came out and said it actually wasn’t a big problem and fixed it for a few hundred bucks!"

TJ B.

★★★★★

"Cardinal was great. Called them for a second opinion after the first company told us we needed a new furnace. The tech from Cardinal, Jordan, was very professional and thorough. His diagnosis was that our furnace needed a little TLC. Did not identify any major issues. Told us about their bi-annual service program and how they could help us extend the life of our HVAC system. Highly recommend."

Matt D.

★★★★★

"Cardinal heating and cooling is great! We had a panic one evening after hours during below 0 temps when our heater wasn’t responding. Cardinal responded immediately with troubleshooting steps and walked us through what to do. What they suggested worked and our family was able to sleep cozily that night!"

Rachel M.

★★★★★

"Every person I’ve interacted with at Cardinal has been knowledgeable, respectful, solution-oriented, and refreshingly honest. They’ve truly worked miracles keeping my older system running efficiently and reliably for as long as they have."

Arielle Z.

★★★★★

"Great responsive service. We have used them for the past 5 years + and never disappoint. We have dealt with both the owner on a holiday and Jordan several times which is nice to have consistency. very nice and professional. They don't try to fear monger or scare you with expensive solutions either. Trust worthy."

Frequently Asked Air Conditioner Maintenance Questions

What is a whole-home air purifier?

A whole-home air purifier is an indoor air quality system that works with your HVAC equipment to help clean air as it circulates through your home or business. Unlike a portable purifier that treats only one room, a whole-home system is designed to deliver cleaner air throughout the property.

How is a whole-home air purifier different from a standard air filter?

A standard HVAC filter primarily helps protect the heating and cooling equipment from dust and debris. Higher-quality filters can also help capture some airborne particles, but they are not the same as an advanced purification system. Whole home air purifiers are designed to provide additional indoor air quality support by helping reduce certain airborne contaminants, odors, and particles as air moves through the HVAC system.

What are the benefits of installing an air purifier?

A professionally installed air purifier may help improve indoor air quality, reduce odors, support a cleaner living or working environment, and provide additional filtration or purification beyond a standard HVAC filter. Benefits can vary depending on the system installed, the condition of your HVAC equipment, filter maintenance, airflow, and the specific indoor air quality concerns in your property.

Can an air purifier help with allergies?

An air purifier may help reduce certain airborne particles that can contribute to indoor allergy discomfort, such as dust, pollen, pet dander, and other allergens. However, results can vary based on the system, the source of the allergens, and how your HVAC system circulates air. Our technicians can help you choose an option designed around your indoor air quality goals.

Can an air purifier help with odors?

Yes. Certain air purification systems are designed to help reduce odors from pets, cooking, smoke, mustiness, and other indoor sources. The right solution will depend on the type of odor, your HVAC setup, and whether there are underlying issues such as moisture or poor ventilation.

Can you repair an existing air filtration system?

Yes. Most air purification and filtration systems require periodic maintenance to keep them operating effectively. Maintenance needs may include replacing filters, cleaning accessible components, checking system operation, or replacing UV lamps depending on the type of system. Our team can explain the recommended maintenance schedule for your specific equipment.

What is an Energy Recovery Ventilator (ERV)?

An ERV is a whole-house ventilation system that exchanges stale indoor air for fresh outdoor air. As the two airstreams pass through the unit, it transfers heat and moisture between them, so incoming air is closer to your indoor temperature and humidity before it enters your home.

Is an ERV the same as an air purifier?

No. An air purifier cleans the air already circulating inside your home. An ERV brings in fresh, filtered outdoor air and sends stale indoor air outside. They solve different problems, so many homeowners use both for the best overall indoor air quality.

What is the difference between an ERV and an HRV?

Both recover energy from the air leaving your home. An HRV transfers heat only, while an ERV transfers both heat and moisture. In a climate like Chicago’s, with humid summers and dry winters, that moisture transfer helps keep indoor humidity more comfortable year-round.

Can an ERV work with my existing HVAC system?

In most homes, yes. An ERV can often connect to your existing ductwork and run alongside your furnace and air conditioner. Our technicians will look at your current setup, confirm compatibility, and recommend the right unit and installation approach.

How often does an ERV need maintenance?

ERV filters should be checked and cleaned or replaced regularly, and the core needs periodic cleaning based on the manufacturer’s guidance. Having your ERV inspected during routine HVAC maintenance helps keep it running efficiently.
