Hard to believe we were already thinking about Fall this time last year. I think we have plenty of Summer left.

We know there’s still plenty of summer left...

Spotted on the Marine Corps Base at Twentynine Palms: proof that when the mission matters, air conditioning matters too. 🇺🇸

Your home may not be operating under austere conditions, but a Missouri summer can certainly feel like it.

A few angry hornets are a small price to pay to get your A/C running again. 😅

Upgrade your thermostat with Leiber HVAC, and one thing is guaranteed: it’s getting one of these awesome stickers.

Your laptop can have one too; or it could even be a tasteful tattoo if you’re really committed to indoor comfort. 😂

We’ve seen a real uptick in Ameren customers choosing Leiber HVAC to help navigate the Fast Track HVAC PAYS program—and the savings have been significant. If you’re in St. Charles County, it’s worth taking a look!

Ameren Missouri helps make heating and cooling upgrades more affordable by offsetting upfront costs and allowing you to pay for equipment monthly on your utility bills.

The Fourth of July may be in the rearview mirror... 🇺🇸
..but we're still rolling because Missouri summer isn't taking a day off.

We're still a family-owned business that believes in taking care of people the way we'd want someone to take care of our own family.

If your equipment still has life left in it we'll do everything we can to keep it running before recommending replacement.

We'll always work with you, explain your options, and help you find a solution that fits your home and your budget.

Thanks for trusting Leiber Heating & Air Conditioning to keep your family comfortable.

Add a comment if you've seen one of our trucks in your neighborhood!

🇺🇸 From our family to yours... stay cool.
