HOME VENTILATION

ERV Installation: Fresh Air for Tight Homes, Without the Humidity

New and well-sealed homes need mechanical fresh air — but in the Upstate, opening a window or running a plain fresh-air intake means pulling in 70° dew point air all summer. An Energy Recovery Ventilator brings in fresh outdoor air, exhausts stale indoor air, and transfers moisture between the two streams so the fresh air arrives dry. It’s the right whole-home ventilation choice for the large majority of Greenville-area homes.

WHY ERV INSTALLATION

Ventilation That Works With a Humid Climate,
Not Against It

The tighter a home is built, the less it breathes on its own — and the more it needs a controlled source of fresh air for air quality, odors, and moisture from cooking and showers. The problem in a humid climate is that fresh air is wet air. An ERV’s core passes outgoing indoor air past incoming outdoor air, recovering the cooling and rejecting most of the incoming moisture before it reaches the living space. That’s why an ERV, not an HRV, is the standard choice here.

KEY BENEFITS

Why Homeowners Choose ERV Systems

An ERV system is about more than simply moving air. It helps improve fresh-air exchange while supporting a more balanced indoor environment throughout the home.

  • Continuous fresh outdoor air, filtered, delivered on purpose
  • Stale, humid indoor air exhausted from bathrooms and living areas
  • Most incoming humidity rejected before it enters the home
  • Lower cooling load than open windows or a plain fresh-air duct
  • The fresh-air solution for homes conditioned by ductless systems
  • Quiet, low-power operation that runs around the clock
A GOOD FIT FOR

When an ERV Is the Right Choice

An ERV makes sense wherever a home is tight enough that natural air leakage isn’t providing fresh air — which describes most of what’s been built in Greenville and Spartanburg Counties in the last decade.

  • New construction and recently built homes
  • Homes retrofitted with spray foam or air sealing
  • Homes heated and cooled by ductless mini-splits, which don’t bring in outdoor air on their own
  • Households with allergies, asthma, or lingering odors and stuffiness
  • Anyone who wants fresh air without a damp, sticky house in July
OUR APPROACH

Designed With the Heat Pump System, Not Bolted On Afterward

An ERV’s fresh air has to go somewhere, and its exhaust has to come from the right rooms. I design ventilation as part of the whole comfort system — where the fresh air enters, where stale air leaves, how the flow rates are balanced, and how it coordinates with a ductless or ducted heat pump so the fresh air is conditioned before you feel it.

  • Fresh-air and exhaust locations planned around the floor plan
  • Airflow balanced and verified at commissioning
  • Sized to ASHRAE 62.2 ventilation rates for the home
  • Integrated with the Mitsubishi system, not fighting it

We were very impressed with this company. We had an issue with our bathroom venting through the attic to the roof. David came out, assessed the problem, and provided us with reasonable quotes for various options to correct the issue. The work was done efficiently and we were even provided with before/after videos for verification and future reference. We would definitely recommend this company.

David installed our new fully electric multi-zone heat pump system, mixed ducted/ductless to replace old AC & gas furnace. The work was thorough, detailed, and neat. David went over and above to keep us comfortable, resolved some historic oddities in our HVAC system, and provided support with app controls. Communication and admin support regarding scheduling, rebates, financing, permitting etc. was all very clear & handled quickly. All around quality experience, good folks!

I worked with David at VisionAiry Heating and Cooling for the installation of a new heat pump and furnace. The first thing that impressed me about him was the lack of pressure and his high level of honesty. He didn’t try to “sell me” on anything - he was honest about the state of my heating system and answered all of my questions patiently. This all made me feel I could trust him. As we worked toward a plan, he was willing to talk me through things over and over, and was excellent at communicating. When it came time for the install, everything went well! He installed the furnace one day and the heat pump next - they look and work great! The team was thorough and the system works great. Super happy with this team and would highly recommend!

David Daher was the ultimate skilled and respectful professional, and I could not be more pleased with how he assessed my situation, carried it out promptly and dependably, and always superbly cleaned up. He's an expert installer and knows his products. He's patient and thorough with questions, and always so very pleasant. I have every confidence and trust in VisionAiry, and look forward to many comfortable years with my new furnace and heat pump. You will never regret choosing this top-notch company!

David was punctual and took the time to explain what was needed, how he would do it and was such a joy to work with! He had to make multiple trips out to my place as we uncovered other electrical things that needed to be fixed first and he was always kind and brought a good energy to the situation when I was feeling stressed. I've told all my Minneapolis friends and neighbors that if they need a bathroom fan or stove vent properly vented that they HAVE to work with David. I'll continue to sing his praises haha 🙂

With boiler heating and no duct work in our house we have been looking to get a mini split system installed to provide some AC. We had it quoted from numerous companies big and small but the price always was too steep. After contacting David and having many back and forth emails as well as him visiting our house the final quote was the most competitive. It is one thing to know what you are doing but it is another to actually care about what you are doing and David has both. From first contact to the finished job David was forthright and honest on everything but also provided a high level of competency and quality for doing the job. I could not be happier with the whole process from beginning to end and highly endorse him for any work he does.
