When Is It Time to Replace Your AC?

  • Frequent repairs or system breakdowns
     
  • Cooling bills keep rising
     
  • Inconsistent temperatures or hot spots

  • Uses outdated refrigerant (R-22)
     
  • AC struggles to keep up on hot days
     

What You Get with a CRS Installation

Personalized Recommendations

We assess your home’s size, layout, and existing ductwork to help you choose the right system — not just the most expensive one. 

Expert Installation

Your new AC is installed by trained technicians — never subcontractors — following manufacturer specs and local code. 

Reliable Equipment

We install trusted brands known for performance and warranty support. 

Clean, Respectful Work

We protect your space, test your system thoroughly, and walk you through your new setup before we leave. 

Central Air & More

 We install more than just traditional central AC systems. Whether you’re upgrading an old system or planning a full HVAC replacement, CRS Heating and Air Conditioning, Inc. can help with:  

High-Efficiency Systems

Modern systems cool better and use less energy. We’ll help you choose one that fits your home and budget — without the upsell. 

Air Handler Replacements

If your blower or indoor unit is aging or failing, we can replace the air handler alone — no need to change the whole system if it's not time yet. 

Upgrades from Older R-22 Systems

Still running on R-22 refrigerant? These systems are outdated and costly to maintain. We’ll replace it with a safer, efficient unit using current refrigerants. 

Matching Coil + Condenser Installs

A mismatched coil can drag down performance. We replace both together when needed — for full warranty protection and better efficiency. 

Paired Installs with Furnaces or Air Quality Systems

Doing both your AC and furnace? We’ll coordinate install timing and make sure everything is sized and integrated correctly — including humidifiers, purifiers, or new thermostats. 

Local Experts You Can Trust

CRS is woman-owned and based in McHenry. We serve the surrounding areas with honest, expert AC installation and replacement services backed by integrity — not sales quotas.
