Frequently Asked Questions

What Are the Signs of a Failing Furnace?

Uneven heating, strange noises like banging or rattling, and rising energy bills without increased usage are key signs of a failing furnace. Musty or burning smells when the furnace runs also indicate potential issues. Regular maintenance from BEL-O Cooling & Heating helps keep your system efficient and reliable throughout the winter.

Why Is Regular AC Maintenance Important?

Routine AC maintenance improves efficiency, reduces breakdowns, and extends your unit’s lifespan. Over time, dust buildup forces your system to work harder, increasing energy costs. BEL-O Cooling & Heating ensures your AC runs smoothly, keeping your home comfortable during O'Fallon’s hot summers while saving on energy bills.

How Can I Detect a Slab Leak?

Unexplained spikes in water bills, the sound of running water when fixtures are off, and damp or warm spots on your floor can all signal a slab leak. BEL-O Cooling & Heating uses advanced detection equipment to identify and fix leaks quickly, protecting your home from costly damage.

What Is Hydro Jetting and How Does It Work?

Hydro jetting is a powerful, eco-friendly method of clearing tough pipe blockages using highly pressurized water.
