Additionally, it’s important to keep the area around the outdoor unit clear of debris, leaves, and vegetation to support proper airflow and cooling efficiency.
Our Appleton HVAC technicians also recommend an annual professional maintenance check to inspect refrigerant levels, electrical components, coils, thermostat, and the system’s overall operation. Here are some A/C maintenance tips to help get you started.

Radiant Floor Heating in Appleton, WI
Radiant in-floor heating systems supply heat directly to the floor of a house. The system depends largely on radiant heat transfer: the delivery of heat directly from the hot surface to the people and objects in the room via the radiation of heat. Radiant floor heating is the effect you feel when you can feel the warmth of a hot stovetop element from across the room. Our radiant floor heating specialists in Appleton use Rehau tubing and IBC high-efficiency boilers.
Read more here for the pros and cons of radiant floor heating. Our Appleton heating contractors also are skilled in boiler services. For boiler services, we specifically install Rehau tubing and IBC high-efficiency boilers.
Indoor Air Quality
Our technicians suggest implementing controlled ventilation systems that perform three essential functions: 1.) introducing fresh outdoor air, 2.) extracting polluted indoor air, and 3.) properly conditioning the air circulating throughout the structure. We offer diverse approaches to purify your indoor atmosphere with professional air purification solutions. Reach out to the Modern HVAC team to discuss your specific concerns, and we’ll identify an appropriate air purification system for your home.
We also offer Energy Recovery Ventilation (ERV) technology, which effectively removes airborne contaminants and surplus humidity from indoor environments. These systems efficiently capture thermal energy from outgoing air during colder seasons while pre-cooling and reducing moisture in incoming air during hot, humid conditions. The result is superior indoor air quality for your household and decreased potential for moisture-induced structural damage!
Radon Testing
Detecting radon in its early stages is critical for your household’s health and safety. AprilAire’s radon detection system offers swift, straightforward, and dependable evaluation and treatment options. Modern HVAC can supply you with an AprilAire temporary radon assessment package to evaluate whether your residence and loved ones are protected from concentrations of hazardous radon.
After completing your assessment, our team is available to review your findings, address any concerns, or explore additional solutions. Contact us today for more information about radon testing!
