Fresh Air Without Wasting Energy

Ventilation Systems (ERVs)

Today's homes are built tighter than ever — especially new foam-insulated houses. That's good for efficiency, but it traps stale air, odors, and excess moisture indoors. An Energy Recovery Ventilator (ERV) solves this by bringing in fresh outdoor air while removing stale indoor air — all without wasting energy.

Our Ventilation Options

At 5 Lakes Heating & Air, we install Energy Recovery Ventilators (ERVs) — the right choice for South Carolina homes.

ERVs vs. HRVs

An ERV transfers both heat and moisture, keeping your home balanced in humid climates. HRVs only transfer heat, which is why you'll rarely see them in this region.

Customized Installation

ERVs can be added to many existing HVAC systems or installed during new construction for maximum efficiency.

ERVs include washable filters and require occasional cleaning to keep them performing at their best.

Why It Matters

Why Ventilation Systems Matter

Without proper ventilation, modern homes can feel stuffy and trap unhealthy air. ERVs keep your home fresh and balanced by controlling air exchange intelligently.

Here are the most common problems ERVs solve:

Stale Indoor Air

Constantly refreshes the air without opening windows.

Excess Moisture Indoors

Transfers humidity during exchange to prevent mold and musty smells.

High Energy Loss

Brings in fresh air without making your HVAC work harder.

Poor Air Quality in Tight Homes

Especially important in foam-insulated or tightly sealed houses.

Routine ventilation doesn't just improve comfort — it protects your health and preserves indoor air quality.

Common Misconceptions About Ventilation

Homeowners often misunderstand how ventilation works:

"My home gets enough fresh air naturally."

Not true in modern foam-insulated or energy-efficient homes — they're too tight to allow proper airflow.

"I'll just crack a window."

That lets in hot, humid South Carolina air, raising energy bills and introducing moisture problems.

ERVs give you the fresh air you need without the drawbacks.

Custom Solutions for Every Home

Every home is different. Some only need a basic fresh air ventilator, while others require a full ERV system for balanced humidity and comfort. We'll help you choose the right option based on your goals, budget, and home design.

Extremely prompt and very helpful on the phone to troubleshoot before coming out. Ready available parts and he was very thorough in cleaning and checking to make sure everything else was in order with my HVAC unit. I highly recommend using Justin.

AC Diagnostic & Repair

So grateful for Justin. We had a refrigerant leak in our AC unit and as a result, had no cool air for a day. I contacted Justin and he was very prompt to come out the evening of the same day that I called him. We have a newborn and knowing that, he made sure to get us taken care of ASAP. I had contacted another company the day before, but Justin beat their price significantly for the repair. Thank you! Will gladly use 5 Lakes again!
