Time to Replace Your Furnace?

Whether your system is aging, struggling to keep up, or completely shut down, CRS Heating and Air Conditioning, Inc. can help you find the right furnace — and install it the right way. We’re based in McHenry, woman-owned, and focused on clear answers without the upsell.


We install high-efficiency gas and electric furnaces, and we’re happy to help you compare options based on your home, budget, and comfort needs.

How to Know It’s Time for a New Furnace

Furnaces typically last 15–20 years, but efficiency and reliability can decline long before that. If you’re facing frequent repairs, uneven heat, or rising energy bills, it might be time to upgrade.


We can assess your current system and walk you through replacement options — no pressure, just facts.
 

What You Get with a CRS Installation

Proper Sizing Matters

We’ll evaluate your home’s layout, insulation, and ductwork to ensure the new system is correctly matched. 

Clean, Safe Work

We follow all code requirements, test gas connections, and verify airflow and temperature output before we leave. 

No Subcontractors

Every install is done by CRS technicians who care about doing the job right. 

Efficiency That Fits

We install trusted brands and models with Energy Star ratings, two-stage or variable-speed options, and modern controls that improve comfort and reduce operating costs.

Thinking About Repair vs. Replace?

 If your current furnace still has life in it, we’ll tell you. But if replacement is the smarter choice long-term, we’ll explain why — and help you make the decision with confidence.
