We want to know.. Which of these numbers below suits you best when turning on the furnace for the first time? Do you do your own maintenance and switch out the air filters? Or, are you more likely to switch it on and hope for the best? Tell us! We promise we won't judge 😉

Don't forget, we're always here to help, 217-342-2323.

When should you turn on your furnace for the first time?

There's no magic date on the calendar- but when those chilly mornings start rolling in, it's time to think about turning the heat back on.

A good rule of thumb; if your home is consistently feeling uncomfortable or indoor temperatures are dropping into the 60s, it's time to fire up the furnace.

Before you do, take a few minutes to:

- Change your air filter
- Make sure vents aren't blocked
- Clear away anything stored around your furnace
- Turn your thermostat up gradually
- Pay attention to any unusual smells or noises

And if your furnace doesn't sound, smell, or operate quite right, don't wait until the first really cold night to find out you have a problem.

Let Merz Heating & Air Conditioning make sure your system is ready for the season. Give us a call today, 217-342-2323.

Today we remember the lives lost on September 11, 2001 and honor the brave first responders, military members, and ordinary Americans who showed extraordinary courage in the days that followed.

Wednesday Wisdom from Merz!

Fall is right around the corner, and your HVAC system is about to go from cooling your home to keeping it warm and cozy.

Before those chilly mornings arrive, take a minute to make sure your system is ready to make the switch!

- Check or replace your filter
- Make sure vents aren't blocked
- Listen for unusual noises
- Schedule a fall maintenance check if it's been awhile

A little preparation now can help prevent an unexpected breakdown when you need your heat the most.

Call us today to schedule a fall check up, 217-342-2323.

Whether it's a commercial or residential project we plan ahead to do it once and do it right!
