If your home feels stuffy, humid, or difficult to ventilate without losing conditioned air, an ERV system can bring in fresh air while maintaining efficiency. In tightly sealed homes across Madison and Greater Wisconsin, poor ventilation can lead to lingering odors, excess moisture, and inconsistent indoor air quality.
Southport Plumbing, Heating, and Cooling provides Energy Recovery Ventilator (ERV) system installations designed to integrate with your existing HVAC setup. Each system is installed to improve airflow, balance indoor conditions, and maintain energy efficiency without overworking your equipment. Schedule ERV installation today to improve airflow and ventilation throughout your home.
When to Consider ERV Installation
Homes with limited natural airflow or tight construction often need mechanical ventilation to maintain air quality.
You may benefit from ERV installation if you notice:
- Condensation forming on windows or walls
- Dry indoor air during the winter months
- Persistent humidity during summer
- Lingering odors that do not clear easily
- Poor indoor air quality despite filtration systems
These conditions often indicate that fresh air exchange is not happening effectively.
How ERV Systems Improve Ventilation
An ERV system replaces stale indoor air with fresh outdoor air while transferring heat and moisture between the two air streams. This allows ventilation without creating large temperature swings or increasing system demand.
The result is more consistent airflow, improved humidity balance, and better indoor air conditions throughout the home.
What Happens During ERV Installation
Proper installation ensures the system works efficiently and integrates correctly with your home.
- Evaluate home layout and airflow needs: Identify areas that require ventilation
- Select installation location: Typically attic, mechanical room, or utility space
- Connect to ductwork or install ventilation lines: Ensure proper air distribution
- Integrate with HVAC system: Sync operation with heating and cooling equipment
- Balance airflow: Adjust intake and exhaust for consistent performance
- System testing and setup: Confirm proper operation and control settings
This process ensures the system delivers consistent fresh air without disrupting your existing HVAC performance.
How ERV Systems Integrate With Your HVAC
ERV systems can work alongside your current heating and cooling system or operate through dedicated ventilation lines.
Integration depends on:
- Existing ductwork layout
- Available installation space
- Home size and airflow requirements
When properly installed, the ERV supports your HVAC system by improving airflow and reducing excess moisture without increasing system strain.

My experience started with a call to Southport for a second look opinion. They were highly recommended. The technician Tyler was able to find and explain the problem/s I was having with my 20 year old furnace and AC unit. He went over my options thoroughly, quickly set up a time for Justin to go over those options with necessary numbers, and the appointment was made for a new furnace and AC. The technicians Max, Diego and Aaron did a fantastic job with removal of my existing system and new installation. They treated me and my home with respect, paying great attention to detail. Max explained the process as they went along, making sure any question I had was answered. Nathan, the sales manager was even kind enough to stop and make sure I was happy with the whole process. The entire staff exceeded my expectations and were so professional, courteous and respectful, which is especially appreciated, as home repairs can be quite stressful. I highly recommend Southport.

Southport responded quickly and effectively in replacing our sump pump on the day of the storm on 4/17/2026 where our lower level of our home flooded. Both Alex and Andy responded. Despite not being on call, Andy responded as a neighbor and ensured that the sump pump got installed himself so that the overflow would stop and damage would be minimized. This included working in the midst of the water at 3am. I suspect the water damage and overall impact would have been exponentially worse if not for Andy’s dedication to solving the problem. I was out of town when this occurred and both my spouse and I are very grateful for Andy and Southport’s prompt emergency response. Approximately a week later we proceeded with installation of a battery backup. Thank you for the service and assistance in mitigating this very stressful and difficult situation.

I saw Southport at a remodeling trade show at Monona Terrace in Madison, and requested an inspection of the heat pump in my 40+ yo condo. The person scheduling the appointment handled a last minute change to the appt professionally and accommodated my request. The technician was also very professional and knew his trade incredibly well. When the inspection unsurprisingly showed the unit needed replacement, I was still provided with repair options, pricing on individual repairs, and payment methods. A definite bonus was the tech was personable and empathetic, going as far as laughing at my dad jokes (they're bad, trust me 🙄). Finally, there was no pressure to pay for additional services, or any hard sales to purchase anything or repair on the spot. Overall a great experience, I will be using Southport going forward.

Last week we had Tornados in our area. While listening to the warnings, the meteorologist mentioned a back up sump pump would be beneficial to have. I scheduled an appointment with Southport home services. Andrew came out and explain how the system works. He then gave me prices.. He was able to install the system the same day. I highly recommend Southport Home Services.

My technicians were quite well informed and highly skilled in replacing all of the plumbing in the basement (hot water heater, sump pump, back up sump pump and battery, ejector pump). Highly recommend this company and the specific technician that performed all the work.

I noticed water on the floor on Friday morning below water heater. Called and service tech came out early afternoon. Problem confirmed and new one installed by late afternoon. Entire process was smooth and without incident. Tech was very professional and consistently communicated status so I stayed informed.

With all the flooding we had I was concerned about how often my sump pump was running and if it was working correctly. Tanner from Southport was here promptly and checked my sump pump over as well as the drainage hose I installed making sure everything was working as expected. He explained what to watch for as well as the services Southport offered. I am grateful for his professionalism as well as Southport's Shield program!

Southport is always great!! I've had them out for a couple of planned items in the past, so when my sump pump died this morning, they were my first and only call. Not only did they give me a 2 hour time frame in the first phone call, but they continued to call me back and update me as the technicians arrival time changed! Justin was the technician dispatched to my house. He was awesome. There's simply no other word for it. He looked at the pump, gave me 3 quotes, let me pick & choose the features & warranty I wanted, then immediately went to work because all the parts were already on his truck. He also gave me the name of a water remediation company they work closely with and coached me on what questions to address with that other service provider!! I will truly never call anyone else again. Southport has earned my business FOR LIFE!
