Most residential contractors in the area only offer one main service. At Green Factor Insulation, we specialize in everything related to the building envelope. This lets us address a variety of issues you’d normally have to call two or three contractors for.
Your home’s energy efficiency, performance, and comfort depend upon multiple elements of the building envelope working together, so it takes a team with comprehensive expertise to resolve any problems. We provide:
Green Factor helps homeowners select smart thermostats that are fully compatible with their existing HVAC equipment and installs them for reliable performance from day one. Our team handles everything so the thermostat communicates properly with your heating and cooling system and responds the way it should. It’s a small upgrade that carries big benefits for comfort and energy efficiency.
We are one of the leading air sealing and home insulation companies in Kansas City and Northeast Kansas. We go above minimum code requirements and offer multiple insulation types for attics, walls, and crawl spaces.
We are KDHE-licensed radon professionals providing testing services, indoor air quality solutions, and radon mitigation systems backed by a 10-year performance warranty.
If your HVAC system has croaked, we offer furnace and central air system repairs and replacements and more. We’re the leading heating, AC, and heat pump company in Kansas City!
Through Green Factor Roofing, we offer roof replacements, roof repairs, and gutter installations. We’re authorized by Klaus Roofing Systems and offer a 50-year warranty.
Inconsistent temperatures, hot second floors, and drafts are far too common in Kansas City homes. Besides causing discomfort, they also increase heating and cooling costs. Green Factor Insulation puts a stop to it.
A lot of people have moisture in their attic and falsely assume it’s because of a leak. Most of the time, it’s actually condensation caused by poor insulation and air gaps. Our attic insulation installers can address the problem and help keep your home mold- and moisture-free.
Damp, pest-ridden, moldy crawl spaces shouldn’t be seen as the norm. Our team can turn even the worst crawl space into a clean, dry area that you’ll feel comfortable having beneath your home, while also preventing energy loss.
Radon is a dangerous gas that can enter your home from the ground up, compromising your family’s health and safety. We offer warranty-backed mitigation services that reduce radon to safe levels.
As building scientists, we get to the heart of the issue before jumping to conclusions. Whereas other companies will give a quick peek into your attic and recommend a solution, we conduct a thorough analysis to make sure we solve your problem the first time. Here’s what our process looks like:
Green Factor’s approach also reflects a commitment to smarter energy use and responsible building practices. The team looks for ways to reduce waste wherever possible and recommend materials that support both home efficiency and long-term sustainability. From recycled-content insulation options to solutions that help homeowners lower energy consumption, every recommendation is made with an eye toward creating healthier homes and a more resource-conscious future.
Routine maintenance helps catch small issues early, reduce energy waste, and extend the life of your equipment. With our Green Factor Shield Program, members receive:
Big home projects don’t have to mean high upfront costs. Flexible monthly payments make it easier to move forward with the upgrades your home needs now while spreading payments out over time. The Green Factor team can walk you through available options and help you choose a monthly payment schedule that fits your timeline and budget.
Smart thermostats give you better control over your home’s comfort while helping your heating and cooling system run more efficiently. By learning your schedule, adjusting automatically, and allowing remote access from your phone, these systems help reduce unnecessary energy use and keep temperatures consistent throughout the day. Instead of constantly adjusting settings, your home adapts in the background so comfort stays steady without extra effort.
Green Factor helps homeowners select smart thermostats that are fully compatible with their existing HVAC equipment and installs them for reliable performance from day one. Our team handles everything so the thermostat communicates properly with your heating and cooling system and responds the way it should. It’s a small upgrade that carries big benefits for comfort and energy efficiency.
Green Factor is always looking for driven, friendly, outgoing, and dependable people who take pride in their work and enjoy helping homeowners feel taken care of. If you want to be part of a team that supports each other and delivers service that wows on every call, you’ll fit right in here.
