FAQ
-
We primarily serve homeowners within a 15-mile radius of the Wisconsin State Capitol in Madison, including Fitchburg, Middleton, Verona, Sun Prairie, McFarland, Cottage Grove, DeForest, Waunakee, and Oregon. If you live outside this radius, we are still happy to help—a standard trip fee will simply be applied based on the distance.
-
Every home is constructed differently, and every system has unique layout, airflow, and comfort needs. Choosing equipment solely based on a flat price often leads to sacrificing overall comfort, resulting in uneven temperatures, louder operation, and higher energy bills. We perform an initial diagnostic evaluation to provide you with clear pros, cons, and honest options tailored to your budget and long-term goals.
-
Most HVAC contractors simply swap out equipment when something breaks. We diagnose homes using building science, data, and performance testing. Instead of treating symptoms, we evaluate airflow, pressure, duct performance, and humidity to solve the root cause of your comfort issues.
-
Temperature imbalances are rarely caused by a broken furnace or AC unit alone. They are typically caused by duct performance issues, improper equipment sizing, house pressure imbalances, or uneven airflow. Our Whole Home Comfort Analysis pinpoints exact causes so we can balance your entire living space.
-
Our maintenance service goes beyond a quick check. We clean, service, and test your system against the manufacturer's best practices and standards. This ensures your equipment operates efficiently, outlasts its standard lifespan, and prevents unexpected breakdowns during extreme summer heat or winter cold.
-
When a component fails, we don't just replace the broken part—we determine why it failed and check if surrounding components were damaged. We present you with a full picture of where your system sits in its lifecycle, outlining the pros and cons of repairing versus replacing so you can make an informed choice.
-
Yes! Modern cold-climate heat pumps are engineered to efficiently heat homes even in severe Midwestern winters. They offer lower operating costs, precise humidity control, and reduced carbon footprints compared to traditional heating options.
-
Newer homes are built tighter for energy efficiency, which traps dust, allergens, VOCs, mold spores, and excess humidity inside. Upgrading filtration, air purification, or ventilation (such as ERV/HRV systems) ensures fresh, healthy air circulates through your home year-round.
