🚨 Public Service Announcement from Leiber HVAC 🚨

Have you done the thing with your ceiling fans yet?

I've spent more time than I care to admit staring at a spinning fan and asking myself: "Wait... is that clockwise or counterclockwise?"

Anyone else? 😂

☀️ Summer = Counterclockwise (but, fact check me on that...)

A friendly annual reminder from Leiber HVAC ☀️❄️

Take a few minutes and gently hose off your outdoor AC condenser or heat pump unit.

Pay extra attention to the side of the unit facing your house — that’s usually where cottonwood, grass clippings, dust, and debris build up the most. It’s easy to miss because you rarely see that side!

A gentle rinse (not a pressure washer!) can help your system breathe easier heading into Missouri summer season.

Little maintenance now can prevent big headaches later. 👍

Need us? Leiber HVAC is always here for second opinions, maintenance, and keeping your home comfortable.

Free tip: hose off your air conditioner!

This is what your A/C unit looks like when it’s begging for help.

This photo isn’t from some abandoned house. It’s what happens when grass clippings, dust, and pollen build up on your outdoor condenser unit.

Dirty coils force your system to work harder = higher bills 💸

Less heat escapes from your home = less comfort 😓

And believe it or not, a little rinse with your garden hose actually helps cool your house.

When water hits clean coils and evaporates, it helps pull heat away from your system faster, like a built-in boost!

✅ Don’t use a pressure washer
✅ Just hose it gently from top to bottom
✅ Do it after you mow, and once more during peak summer heat

Want a pro to check your whole system? Give Leiber HVAC a call. Family-owned, Saint Charles-rooted, and here to help.

Whether it’s a repair, second opinion, maintenance visit, or full system replacement… we don’t take your trust lightly.

If we've had the privilege of serving your home, we’d love for you to stop by our Nextdoor page and say hello:

The best HVAC repair bill is the one you never have to pay.

Most disasters start as a small refrigerant leak, or a weak capacitor, or a loose wire. Little issues that quietly grow while your system keeps limping along.

That’s why our Planned Service Agreements (PSAs) are one of the smartest investments homeowners make.

Our residential maintenance members jump to the front of the line, but even more importantly, we catch the little stuff BEFORE it becomes a no-A/C call on the hottest night of the year.

If you’ve been putting off maintenance, this is your reminder: preventative care beats emergency repair every time.

Give Leiber HVAC a call and ask about our Planned Service Agreements. Your future self may thank you.

It's funny, at about this same time last year we were thinking the same thing: we’re thrilled it’s not 95° with 95% humidity right now.

But don't let the forecast fool you. The heat is creeping in like Cardinals fans in May...way too confident, way too early.

Now’s the time to call Leiber HVAC before your system starts wheezing like it’s climbing stairs in July.

That one room… you LOVE it.
All the windows. All the sunshine. ☀️

But by July?
It turns into a greenhouse. 🥵

If you’ve got a room addition, sunroom, or “why is this room 10° hotter than the rest of the house?” situation…
A mini-split might be your new best friend.

👉 Quiet. Efficient. No ductwork needed.
👉 Perfect for rooms your system just can’t keep up with.

Leiber HVAC can make your favorite room feel like your favorite room again.

Call us at 636-947-0428 and ask us about mini-splits!

Missouri Spring Checklist:
✅ Mow the yard
✅ Mulch the flower beds
✅ Watch the radar every 14 minutes
✅ Make sure your A/C survives the next weather identity crisis

If you’re tuning up the yard, tune up the house as well! Your condenser deserves spring maintenance too. Call Leiber HVAC before summer shows up angry. 636-947-0428

Have you seen Project Hail Mary yet?

At Leiber HVAC, we channel our inner Ryland Grace every day…

Tech walks into your living room… immediately senses something’s off…

“Alright… outdoor ambient’s pushing 92°…”
“Superheat’s high… subcooling’s a little off…”
“Charge looks close though… not a refrigerant issue…”
“Airflow’s gotta be low… we’re not transferring heat like we should.”

**mentally scribbling equations like a space scientist**

Yeah… we’re HVAC nerds 🤓

Because when the science is right, your home feels right.

👉 If it doesn’t, call Leiber HVAC..one of our scientists will be happy to come out and run a diagnostic.
