Armstrong Air A/C



  • Up to 20.0 SEER Efficiency Rating
  • Pro Series™ Systems
  • Comfort Sync Compatible
  • True Variable-Capacity Cooling
Rather than running at one or even two speeds, the 20LX Inverter-Driven Scroll Compressor changes its speed in small, precise increments and adjust cooling up and down like a dimmer switch. So temperatures are held exactly where you want them, even in extremely hot weather.



  • Up to 16.0 SEER Efficiency Rating
  • Single-Stage Scroll Compressor
  • ENERGY STAR Certified
  • Heavy Duty Blanket Compressor
The heavy-duty blanket compressor greatly reduces operating sound so your outdoor entertaining is not interrupted.

A/C Preventative Maintenance

Air Conditioner Repair

When your air conditioner isn't running efficiently or reliably call your local A/C repair experts at Leonard Heating & A/C

Our team of air conditioner specialists can take care of any repair your system needs.

If your A/C is old and not very efficient we suggest replacing your outdated air conditioner with a high-efficiency system from Armstrong Air.

A/C Replacement & New Installations

Old inefficient and unreliable air conditioners cost a fortune to keep running summer after summer.

A good way to prevent repair costs from adding up is to replace your old A/C system with a high-efficiency and incredibly reliable air conditioner from Armstrong Air.
