Is your air conditioner ready for another Missouri summer?

Your AC works harder during the summer than almost any other appliance in your home. When temperatures climb, your system runs longer and more frequently to keep your family comfortable.

Regular maintenance can help:

✔️ Improve energy efficiency
✔️ Lower monthly utility bills
✔️ Extend the life of your system
✔️ Catch small issues before they become expensive repairs
✔️ Reduce the risk of a breakdown during the hottest days of the year

A little preventative maintenance now can save you from a lot of frustration later.

If your AC hasn’t been inspected recently, now is the perfect time to make sure it’s ready for the heat ahead.

Need help with electrical service for your HVAC system, thermostat, or related home electrical needs?

💡 Looking for an easy way to lower your energy bills this summer?

A few small changes can make a big difference in both comfort and monthly utility costs.

Here are 5 simple ways to save energy:

✔️ Set ceiling fans to rotate counterclockwise to help circulate cool air.

✔️ Use bathroom and kitchen exhaust fans to remove heat and humidity.

✔️ Replace HVAC filters regularly and keep up with AC maintenance.

✔️ Keep lamps, TVs, and other heat-producing electronics away from your thermostat.

✔️ Upgrade to LED bulbs—they use less energy and produce less heat.

You don’t always need major upgrades to improve efficiency.

Sometimes a few simple adjustments can help your home stay cooler while using less energy.

Have questions about improving your home’s electrical efficiency?
The team at Mundwiller Electric is always happy to help.

When you need electrical services, keep us in mind.

Summer Energy Saving Tip: 💡

🌡️ Avoid placing heat-producing electronics directly beside your thermostat whenever possible.

Many homeowners don’t realize that lamps, televisions, and other electronics generate heat.

When these items are located near your thermostat, they can trick it into thinking the room is warmer than it actually is.

Meaning your home might feel cooler throughout than you intended - and your energy bill might end up higher than you anticipated!

It’s been an unexpected evening.

Many of you have reached out after seeing the fire near our showroom, off highway A. We wanted to share an update tonight.

First and foremost, our entire Mundwiller Electric team is safe, and we are incredibly thankful that the building was empty and no one was injured.

While our showroom will be temporarily closed, we are operating remotely to serve our customers. We ask for patience as we sort through the logistics. We will share additional updates as we know more.

We also want to acknowledge that the fire originated at our neighboring business, Cabinet Concepts.

Our thoughts are with them as they navigate this as well.

More information will be shared as it becomes available. Until then, thank you for your patience, your kindness, and your continued support of local businesses.
