Frequently Asked Questions About HVAC in Merrimac

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

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

For furnaces, schedule replacement in late summer or early fall before the intense Wisconsin winter cold hits, ensuring availability and avoiding emergency premiums. For air conditioners, aim for spring or early fall to avoid the peak summer demand. Scheduling during these shoulder seasons in Merrimac often provides better installer availability and potential promotional pricing.

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

Merrimac experiences high humidity in summer and very cold, often sub-zero winters. This demands a system with a high SEER rating (16+) for efficient cooling and a high AFUE rating (90%+) for heating. Given the temperature extremes, investing in a properly sized, two-stage or variable-speed system is wise for consistent comfort and energy savings year-round.

3Are there local regulations or rebates for HVAC upgrades in Wisconsin I should know about?

Wisconsin has uniform mechanical codes for HVAC installations that licensed contractors must follow. More importantly, focus on utility rebates: Focus on Energy, Wisconsin's statewide program, and local utilities like Alliant Energy often offer significant rebates for installing high-efficiency furnaces, air conditioners, and heat pumps, which can substantially lower your net cost.

4What should I look for when choosing an HVAC contractor in the Merrimac area?

Always verify the contractor is licensed, insured, and has positive local references. Choose a company familiar with Merrimac's older homes and lake-effect weather patterns, as proper sizing and ductwork assessment are critical. A trustworthy provider will perform a Manual J load calculation, not just base the system size on your old unit.

5My house is drafty in winter. Will a new furnace alone solve this, or do I need other services?

A new, efficient furnace will improve heating performance, but it cannot compensate for significant heat loss. For Merrimac homes, especially older ones, a comprehensive approach is best. Prioritize a home energy audit and address air sealing and insulation first; this reduces the workload on any furnace, lowers bills, and improves overall comfort dramatically.
