The Top 5 HVAC Mistakes Homeowners Make and How to Avoid Them
Brought to you by E & R Heating and Cooling – Serving Milwaukee and the Surrounding Areas

Your HVAC system is the heart of your home’s comfort, especially during Wisconsin’s freezing winters and hot, humid summers. However, common mistakes can leave you with higher energy bills, an uncomfortable home, or costly repairs. At E & R Heating and Cooling, we’ve seen these issues across the Milwaukee metro area, from the bustling streets of West Allis to the peaceful neighborhoods of Shorewood. Here’s what to watch for—and how to keep your system running smoothly.


1. Neglecting Regular Maintenance

HVAC systems need regular attention to perform efficiently. Skipping annual maintenance can lead to dirt buildup, worn-out parts, or even a total system breakdown—leaving you in the cold during Milwaukee’s harsh winters.

Localized Tip: Whether you’re in Brookfield, Franklin, or Oak Creek, scheduling a yearly inspection with E & R Heating and Cooling can prevent these issues. Our team specializes in servicing homes across South Milwaukee, Cudahy, and beyond, ensuring your system is ready for whatever the Wisconsin weather throws at it.


2. Forgetting to Change the Air Filter

In homes from Wauwatosa to Brown Deer, clogged air filters are a common issue. They restrict airflow, causing your HVAC system to work harder and leading to higher energy bills. Plus, dirty filters compromise indoor air quality, which is especially concerning for allergy sufferers in Whitefish Bay or Glendale.

Localized Tip: Check your filters every month, especially if you have pets or live in high-pollen areas like Greenfield or Hales Corners. Need help finding the right filter? Our local team is just a call away.


3. Incorrect Thermostat Settings

Whether you’re adjusting the heat during a Milwaukee snowstorm or cooling down on a summer day in New Berlin, improper thermostat settings can waste energy. Setting the temperature too high or low—or leaving the thermostat at one temperature all day—overworks your system and drives up your utility bills.

Localized Tip: Residents in St. Francis, Shorewood, and nearby areas can benefit from smart thermostats. E & R Heating and Cooling offers professional installation and can recommend models suited to Wisconsin’s weather fluctuations.


4. Improperly Sized Systems

Homeowners in Oak Creek and South Milwaukee sometimes assume that bigger HVAC systems are better. However, a unit that’s too large or too small for your home can cause uneven heating and cooling, short cycling, and wasted energy.

Localized Tip: Whether you’re upgrading in Franklin or building a new home in Cudahy, trust E & R Heating and Cooling to calculate the right system size for your space. Proper sizing ensures consistent comfort, whether you’re in Milwaukee or the suburbs.


5. Ignoring Energy Efficiency Upgrades

With rising energy costs, overlooking energy-efficient upgrades can take a toll on your budget. Homes in West Allis and Brown Deer with older HVAC systems are especially at risk of inflated energy bills.

Localized Tip: Energy-efficient systems are a smart investment for homes across the Milwaukee metro area. Whether you’re in Whitefish Bay or Glendale, our team can guide you through rebates and upgrades to save money and reduce your environmental footprint.
