Our team doesn’t believe in rushed recommendations or one-size-fits-all answers. We take the time to understand what your system is doing, what your home needs, and what solution makes the most sense for your comfort and budget.
Air Conditioning Services
Your cooling system helps manage indoor humidity, improves airflow, and keeps your home livable during the hottest months of the year.
Air Conditioning Repair
Willco provides air conditioning repair for common and not-so-common issues, including weak airflow, warm air from vents, water leaks, frozen systems, electrical problems, and poor overall cooling performance. We look beyond surface problems to address the root cause of any issue for the longevity of your system.
Air Conditioning Installation and Replacement
We also install and replace air conditioning units for Madison homeowners and business owners who are ready to upgrade. If your system is aging, unreliable, or expensive to run, a replacement may save you significant money and frustration over time. We install energy-efficient systems with close attention to quality, performance, and long-term value.
Air Conditioning Maintenance
Annual tune-ups help improve HVAC efficiency, reduce wear and tear, protect warranties, and allow us to catch smaller performance issues before they grow into bigger repairs. If you want to get the most out of your system, routine service is one of the smartest steps you can take.
Heating Services
If your home heats unevenly, your system is making strange noises, or your utility bills are rising without a clear reason, it may be time for professional service.
Heating Repair and Maintenance
Willco provides heating repair and maintenance for gas heating systems, oil heating systems, heat pumps, and other equipment designed to keep your home warm in the colder months. Whether the problem is minor or your system is nearing the end of its useful life, we’ll help you understand your options clearly.
Replacement and Installation for Heaters and Heat Pumps
We also help homeowners compare the benefits of heater repair versus replacement. While many issues can be reliably repaired, replacing an old furnace can improve comfort, efficiency, and reliability. We can walk you through this decision without pressure and help you choose a path that fits your home and goals.
Indoor Air Quality Solutions
If your home air feels too dusty, dry, humid, or stuffy, your heating and cooling system could be part of the solution. Willco helps Madison homeowners improve indoor air quality with products and upgrades designed to support cleaner, more balanced air throughout the home.
Our indoor air quality services include:
We often discuss options like the Lennox PureAir system and Reme Halo LED for homeowners looking to improve filtration and reduce airborne contaminants and odors. If you’re reviewing filtration options, our online filter option tool makes it easy to explore available products.
Why Madison Chooses Willco for HVAC Excellence
A lot of companies handle HVAC work, but what really matters is how they do it.
Our company was founded by Bill Cowan in 1988—from the beginning, Willco has been known for strong technical ability, honest service, and work that holds up over time. In February 2024, ownership changed hands, with Bill still involved while gradually retiring and Doug continuing that same commitment to customer care.
We aren’t trying to be the cheapest option in town. That’s not our brand, and it never has been. Our goal is to deliver quality you can trust, backed by fair pricing, strong workmanship, and service that respects your home and your time.
Local Experience That Builds Trust
Many customers have stayed with us for decades because they know they’ll get clear answers, responsive service, and work done with care. We also bring deep equipment knowledge to every visit. Willco has long been a Lennox dealer and has expanded its offerings to include Mitsubishi and Energy Kinetics as well. That gives homeowners more options when it’s time to repair, replace, or improve a system.
Upfront Pricing and Straight Answers
Nobody likes surprise costs; that’s why we moved to flat-rate pricing for service repairs. Instead of worrying about how long a job takes, customers get upfront pricing before the work begins. That means more clarity, less stress, and better peace of mind.
Quality Work That Puts Comfort First
We’ve always focused on service quality. We don’t cut corners, and we don’t treat home comfort like a quick transaction. Every step in our process matters, from diagnostics and maintenance to installation practices and customer communication. So if you want a company that takes the time to explain things, respects your home, and stands behind the work, Willco does exactly what you’re looking for.
Residential and Commercial Heating & Cooling Services
Residential HVAC Services
Most of our work is focused on residential heating and cooling services, including installation, repair, and maintenance for homeowners who want a more comfortable, efficient, and dependable home. We regularly work with customers who are replacing older systems, solving comfort issues, improving air quality, or trying to prevent breakdowns before peak season.
Commercial HVAC Services
We also support select commercial needs, including commercial refrigeration and related service work for small businesses. Whether the job is residential or commercial, our approach is consistent: clear communication, reliable workmanship, and service that reflects the value of the investment.
HVAC Maintenance Plans for Long-Term Comfort
A good heating and cooling maintenance plan helps you stay ahead of expensive problems. It can also improve energy efficiency, reduce the risk of HVAC breakdowns, and help extend the life of your equipment.
Willco’s Service Partner Plan is designed to be a smarter, more proactive way to care for your heater and air conditioner. Benefits include priority service scheduling, annual high-performance tune-ups, discounts on qualifying repairs and services, reduced emergency-related costs, and added peace of mind throughout the year.
If you rely on your home comfort system every season, maintenance isn’t something to put off. It’s one of the easiest ways to protect your equipment and avoid bigger problems later.
