The standard of operation
The standard of operation
A single-stage unit is either on or off, working at full capacity when in use. With this simplified mode of operation, this product provides the heating and cooling levels you’d expect.
Use Less Energy. Save More Money.
With efficiencies of up to 16.00 SEER2, the EL15KC1 can deliver significant energy savings. In fact, it can help cut your energy bills year-round. It may even help you qualify for energy rebates.
A peacefully quiet environment
To reduce operating sound levels, the EL15KC1 uses a sound-dampening system with a precision-balanced, direct-drive fan to ensure smooth, quiet operation. This lets it operate at a volume as quiet as 72 dB, or the sound of a handheld food mixer.

Great New AC/Furnace
January 13, 2026I just had a leno 2 cycle installed and am very pleased. It's so quiet I can barley hear it running. The unit is also smaller than my old furnace and AC, which gives me more storage space. I haven't received my gas bill yet, but I hope to save some money.
Yes, I recommend this product.

A1 United to the rescue!
January 13, 2026Our furnace developed cracks and had to be tagged. We were able to get our new furnace installed within 24 hours--and our house maintained it's temperature pretty well so we were not cold! Thank you for doing a great job. Our AC unit was installed at a later date.
Yes, I recommend this product.
