How to Lower Cooling Bills This Summer in Wisconsin

Wisconsin summers may be beautiful, but the heat and humidity can send your cooling bills soaring if your AC has to work overtime. The good news? With a few smart habits and the right home comfort upgrades, you can enjoy a cool, comfortable home while keeping energy costs under control.

If you're looking to lower AC bills, improve energy‑efficient cooling, and reduce cooling costs in Wisconsin, these tips will help you beat the heat—without beating up your budget.

1. Keep Up With Annual AC Maintenance

One of the simplest and most effective ways to reduce cooling costs is to schedule a yearly tune-up. A clean, well‑maintained system runs more efficiently and uses less energy.

A professional tune-up includes coil cleaning, airflow testing, refrigerant checks, and system calibration—small steps that make a big impact on your monthly utility bills.

Bonus: A well-maintained system lasts longer and experiences fewer breakdowns.

2. Upgrade to a Lennox High‑Efficiency System

If your AC is over 12–15 years old, upgrading to a high-efficiency Lennox system can dramatically reduce your energy usage. Lennox offers some of the most efficient home cooling products on the market, including:

  • Variable‑speed air conditioners that adjust output to match demand
  • Heat pumps with ultra‑efficient summer performance
  • Lennox Ultimate Comfort System™ for maximum efficiency and comfort

Newer models consume less energy, run quieter, and produce more even, consistent cooling. Wisconsin homeowners often see noticeable savings within the first season.

3. Use Smart Thermostats for Better Cooling Control

Smart thermostats—like the Lennox iComfort® series—help eliminate wasted energy by learning your preferences and adjusting automatically. They allow you to:

  • Set schedules that reduce cooling when you’re away
  • Control your home’s temperature from your phone
  • Get alerts if your system needs service
  • Balance humidity and temperature automatically

This one upgrade can reduce cooling bills by 10–20% without sacrificing comfort.

4. Consider a Zoning System

Not every room in your home needs the same amount of cooling. A Lennox zoning system allows you to control temperatures in different parts of the home independently.

Why zoning reduces cooling costs:

  • You cool only the areas you're using
  • Rooms with heat buildup (attics, sunrooms) get targeted airflow
  • Less energy is wasted on empty spaces

Zoning is especially helpful in two‑story homes and homes with additions.

5. Replace Your Air Filter Regularly

A clogged filter restricts airflow, forcing your AC to work harder—and use more energy. In peak summer, replace your filter every 30–60 days.

Pro tip: Lanz Furnace & Fireplace now offers easy online ordering for filters, making replacements fast and convenient.

6. Reduce Heat Inside Your Home

Small changes can make a big difference in how hard your AC has to work. Try:

  • Closing blinds during peak sunlight hours
  • Using ceiling fans to move cool air
  • Running heat‑producing appliances (ovens, dryers) in the evening
  • Sealing air leaks around doors and windows

These simple steps help maintain more comfortable indoor temperatures naturally.

7. Improve Home Insulation

Proper insulation doesn’t just help in winter—the same protection keeps cool air inside during the summer. Attics are the biggest source of heat gain, so insulating and sealing them can significantly reduce cooling costs.
