Frequently Asked Questions About HVAC in Casco

Get answers to common questions about hvac services in Casco, Wisconsin.

1What is the best time of year to replace my furnace or air conditioner in Casco?

For furnace replacement, aim for late summer or early fall (August-October) before the harsh Wisconsin winter hits. For AC replacement, early spring (March-May) is ideal before the summer humidity arrives. Scheduling during these off-peak seasons in Casco often leads to better availability from local HVAC contractors and can sometimes result in promotional pricing, as opposed to emergency calls during a January cold snap or a July heatwave.

2How does Casco's climate affect the type of HVAC system I should choose?

Casco experiences very cold, snowy winters and warm, humid summers, demanding a system capable of significant heating and dehumidification. We highly recommend a high-efficiency furnace (90% AFUE or higher) paired with a central air conditioner or heat pump. Given the long heating season, investing in a higher-efficiency furnace will provide substantial savings on heating bills. Proper sizing is also critical to handle temperature extremes without short-cycling.

3Are there any local regulations or rebates for HVAC upgrades in Kewaunee County?

While Casco itself may not have specific ordinances, all HVAC work must comply with Wisconsin Uniform Dwelling Code for electrical and venting. More importantly, you should check for available rebates. Focus on Energy, Wisconsin's statewide energy efficiency and renewable resource program, often offers rebates for installing high-efficiency HVAC equipment. Additionally, local utilities like Wisconsin Public Service (WPS) may have their own incentive programs for qualifying systems.

4What should I look for when choosing a local HVAC contractor in the Casco area?

Prioritize contractors who are licensed, insured, and have a proven local reputation for reliability, especially during winter emergencies. Look for NATE-certified technicians, which indicates advanced training. A trustworthy Casco-area contractor will perform a detailed Manual J load calculation specific to your home's construction and our climate, not just recommend a unit based on square footage alone. Always ask for local references.

5My furnace is running constantly in winter. Is this normal for a home in Casco, or is it a problem?

During sustained periods of extreme cold, which are common in Casco, it's normal for a properly sized furnace to have longer run times to maintain temperature. However, if it's running non-stop without reaching the thermostat setting, it indicates a problem. Common local issues include a dirty filter restricting airflow, failing components, or the system being undersized for the home. Have a professional inspect it, as an overworked system will fail when you need it most.
