Lennox Signature Collection 15GCSX Gas Pack Review

Lennox makes a quality lineup of package units and the Lennox Signature Collection 15GCSX is their top of the line.  Like all Signature Series HVAC systems, it uses Lennox’s best components and offers precise control of indoor climate.  This is achieved with 2-stage operation and a variable speed blower. The system runs on low about 65% of the time to provide balanced heating and air conditioning  along with more consistent humidity control and air filtration.  The Lennox 15GCSX gas/electric package unit is a good choice in moderate to warm climates because the 15 SEER performance will reduce energy costs significantly.  It is also popular in residential and commercial settings where indoor air quality must be high.  Before we look at information about pricing, warranty and installation, here are the top features of the Lennox Signature Collection 15GCSX gas pack.

  • 15 SEER air conditioning; 78% AFUE heating. Energy Star qualified.
  • 2-stage scroll compressor for quieter, more efficient operation.
  • R-410A refrigerant is chlorine-free and is safe for the environment.
  • PureAir air purification system is an option for even cleaner air.
  • Tubular heat exchanger delivers superior heat transfer and durability.
  • Heavy-gauge galvanized steel cabinet offers excellent protection of components.
  • Powder-paint finish is resistant to corrosion, fading, chips and scratches.
  • Residential models available from 2 ton to 5 ton capacity.

Lennox Signature Collection 15GCSX Price
This is an expensive package unit and some consumers believe they pay a premium for the Lennox name plate on it.  That is a criticism heard in some Lennox Signature Collection 15GCSX gas pack review posts.  It does have a good track record for reliability however, and others feel the higher price point is justified.  These gas pack prices are consistent with top of the line gas/electric package units from Carrier, Trane and others.

Lennox Signature Collection 15GCSX Warranty
The warranty package on this model is fair, not great.  Lennox offers a 20-year limited warranty on the heat exchanger; 10-year limited warranty on the compressor; 5-year limited parts warranty on the coil and other parts.
