How One Inventor Solved the $10B Multifamily Cooling Problem with AC Ports
The multifamily housing market faces one of its biggest challenges yet: providing affordable, efficient cooling to millions of residents in buildings that were never designed for central air. With energy costs climbing and tenants demanding more comfort, property owners have been stuck between expensive HVAC retrofits and unreliable portable air conditioner setups. That all changed with the arrival of AC Ports, a groundbreaking innovation created by industry expert Ed Pemberton, who found a smarter way to keep America’s apartments cool.
The Origins of AC Ports
Ed Pemberton, a seasoned glass and window manufacturer, spent decades mastering the art of building efficiency. He started in his father’s glass shop at age fourteen and went on to run one of the most respected window fabrication businesses in the Pacific Northwest. Over the years, Pemberton saw a recurring issue across countless multifamily buildings: owners were losing money and tenants were losing comfort due to inefficient cooling options.
Most older buildings were never equipped with central air conditioning, and the cost of installing new systems was staggering. Portable AC units offered some relief, but their makeshift window connections created new problems—leaks, safety risks, and wasted energy. Pemberton saw the need for a permanent, professional-grade solution that could work in any apartment, regardless of age or layout. That vision led to AC Ports, a patented window retrofit system that is now transforming how multifamily cooling is managed across the country.
AC Ports Delivers a Permanent Solution
At its core, AC Ports is simple yet highly engineered. Each unit is designed to fit securely into an existing window frame, creating a sealed, durable opening for portable air conditioners. The installation process takes less than ten minutes and requires no construction, drywall work, or building permits. For property owners, that means they can retrofit entire buildings quickly, safely, and cost-effectively.
The advantages are clear. AC Ports eliminates air leaks, reduces water damage, and enhances building security. Tenants benefit from improved comfort without compromising window safety or appearance. Property managers save on maintenance costs and avoid the headaches of long, expensive HVAC retrofits. It is a win for both sides of the rental market.
Unlike temporary window kits or foam panels that degrade over time, AC Ports is built to last. Its durable construction and precision fit ensure a long-term solution that meets both residential and commercial standards. Once installed, it becomes a permanent part of the property’s infrastructure, providing consistent performance year after year.
Solving a Billion-Dollar Problem
The multifamily cooling market represents billions in lost efficiency, maintenance costs, and renovation expenses every year. According to industry estimates, outdated systems and poor window installations contribute to more than $10 billion in wasted energy and repairs annually. AC Ports directly addresses this challenge by offering a scalable retrofit that delivers immediate results.
For property owners managing large portfolios, scalability is key. With AC Ports, installations can be completed across dozens or even hundreds of units in a matter of weeks. The system requires minimal labor, no tenant displacement, and no waiting for permits. The cost savings and operational improvements are significant, especially for property managers overseeing aging housing stock.
Building a National Network
The success of AC Ports is not limited to its technology. The company has built a national network of licensed installers and franchise partners who are bringing the innovation to cities across the United States. Each partner is trained in professional installation and customer service, ensuring that every building owner receives consistent quality and performance.
This model has allowed AC Ports to expand rapidly while maintaining the craftsmanship and reliability that define its brand. As demand grows, the company continues to empower local contractors and small businesses to participate in the movement, spreading a product that solves a nationwide problem.
Innovation That Lasts
In an era defined by sustainability and efficiency, AC Ports represents a true breakthrough in how the multifamily industry approaches cooling. It is cost-effective, environmentally responsible, and built for scalability. Most importantly, it was designed by someone who understands both the technical and practical sides of building management.
What began as one inventor’s idea has become a national solution to one of real estate’s most persistent challenges. AC Ports is not just changing how buildings stay cool—it is reshaping the future of multifamily comfort and efficiency across America.
