CRS Maintenance Plans

 Real Service. Smart Options. Nothing Skipped. 

Don’t Settle for a “Quick Check”

We Actually Maintain Your System

At CRS Heating and Air Conditioning, Inc., a maintenance visit isn’t just a box-check. We clean, test, and verify every key component to keep your system running safely, efficiently, and reliably — season after season.


You can choose a traditional maintenance plan or a smart monitoring plan (powered by SmartAC.com), with tiered options offering different levels of service and benefits.

Classic Preventive Maintenance Plan

Our traditional plan includes two full service visits per year — one for cooling and one for heating

Each visit includes:


  • Inspection and cleaning of critical components
     
  • Carbon monoxide (CO) level testing
     
  • Gas valve and combustion safety check
     
  • Flame sensor cleaning and testing
     
  • Thermostat operation and response testing
     
  • Airflow measurement and static pressure evaluation
     
  • Blower motor and capacitor check
     
  • Refrigerant level verification and coil rinse (cooling)
     
  • Full electrical inspection — including wiring, connections, and controls
     
  • System startup, operation, and shutdown testing
     
  • Filter inspection and replacement (if provided)
     

It’s more than just a look — it’s real maintenance.

Payment options include:

Annual prepay, multi-year discount, or easy monthly billing

Smart Maintenance Plans (Sensor-Based)

Prefer real-time oversight with fewer scheduled visits? Our smart plans include connected sensors and mobile app monitoring, with tiered options to fit your needs.


All Smart Plans include:


  • SmartAC.com sensor kit for airflow, filter, and condensate tracking
     
  • Mobile app with live system alerts and performance reports
     
  • In-app filter ordering with reminders
     
  • Service only when sensors indicate a need (no seasonal visits on all plans)

Smart Plan Tier Benefits (varies by plan)

Depending on the plan tier you choose, benefits may include:


  • 10% discount on repairs (available in some plans)
     
  • Priority service scheduling (available in some plans)
     
  • One or two in-person tune-ups annually (varies by plan)
     
  • 1-year parts and labor coverage on repairs (elite plan only)
     
  • Reduced after-hours service rates (elite plan only)
     
  • Comfort Credits that accumulate toward future repairs or replacements (amount varies by plan)
     

We’ll help you select the tier that fits your home, your system, and your comfort goals — no pressure, just smart planning.

Optional Add-On Services (Available with Any Plan)

  • Humidifier cleaning (includes service + new pad if needed)
     
  • Water heater flush and safety check (recommended annually)
