Most Southern Illinois homeowners have heard the word geothermal. Not many know what it actually means, or that it might be the smartest home investment they've never considered.

At Collards Heating & Air, geothermal isn't a new offering we're testing out. We've been installing geothermal systems in Southern Illinois for over 20 years. We know the soil, the climate, the homes, and the homeowners. And we genuinely believe geothermal is one of the best long-term comfort solutions available, for existing homes and new construction alike.
Here's what you need to know.

Your yard is basically a battery. Here's how we use it.
A few feet below the surface, the earth maintains a consistent temperature year-round, regardless of what's happening above ground. Geothermal systems tap into that natural, stable energy to heat and cool your home more efficiently than any traditional HVAC system.
In the summer, the system pulls heat out of your home and transfers it into the cooler ground.
In the winter, it pulls natural warmth from the earth and brings it inside.
No burning fuel. No fighting against extreme outdoor temperatures. Just consistent, efficient comfort, powered by what's already beneath your feet.

Lower energy bills: Geothermal systems are significantly more efficient than traditional heating and cooling, which means lower monthly operating costs from day one.

Built to last: Geothermal systems have a longer lifespan than conventional HVAC equipment, making them one of the best long-term investments you can make in your home.

Better for the environment: No fossil fuels. No combustion. Just clean, renewable energy from the earth itself.

Less wear and tear: Because the system isn't fighting extreme outdoor temperatures, it runs more efficiently and experiences less strain over time.

Works for existing homes and new construction: Whether you're replacing an aging system or planning a new build, geothermal is a viable option at either stage.

The timing has never been better.
Ameren Illinois is currently offering residential incentives for qualifying geothermal installations, up to $5,400 back in your pocket.

That's real money that meaningfully reduces the upfront investment of going geothermal. Combined with long-term energy savings and available financing options, the math looks very different than most homeowners expect.

We'll walk you through exactly what you qualify for during your consultation, no guesswork, no runaround.
