Lennox SL18XP1 model utilize a single-stage compressor, so it’s not the most efficient one in the line. However, the heat pump comes with a high efficiency of 18.5 SEER in cooling and 10.2 HSPF in heating; making it Energy Star certified that earned top marks for 2015 as a Most Efficient Product.

The heat pump is also very quiet, so quiet Lennox calls it the quietest in the industry for single-stage compressors. It does this because of the SilentComfort insulation and unique fan blade design so vibrations are kept to a minimum. Sensors that control the fan adjust its speed based on the outside temperature while keeping the indoor temperature nearly constant providing greater comfort.

The Quantum Coil condenser coil is made out of aluminum for the best heat transfer you can get, pulling all the hot air out of your house so you feel nice and comfy during the hot summer. Plus, aluminum resists corrosion which steel cannot, so it will last in any weather, even harsh salty air conditions in coastal areas.

Lennox XP21

Lennox heat pump XP21 operates on two phases unlike the 18, making it one of the most efficient two-stage heat pumps on the market today, and quiet, too.  It delivers 19.2 SEER cooling and 9.7 HSPF heating, plus it is also Energy Star certified which ensures savings.  Those two stages mean your heat pump operates in a lower stage during mild temperatures, and kicks up to a higher stage when the demand is higher contributing in the lower noise level.

The XP21 model also has SilentComfort technology for reduced vibration and peaceful homes.  It even has a sensor that detects if a piece of debris has landed on the fan and it adapts the fan speed to free the item before returning to normal operation. The composite fan blades are also resistant to corrosion from bad weather, giving you years of faithful service.

The XP21 is a super star Energy Star product, earning a Most Efficient 2016 award.

Lennox XP25

The XP25 heat pump is the top of the Lennox line, and one of the best in the industry.  The variable-capacity PreciseComfort inverter driven compressor makes it the most temperature accurate model you can buy and it delivers a stunning 23.5 SEER cooling and 10.2 HSPF heating, the best in the industry. It does this by making micro adjustments, as little as 1%, to keep you home at a steady temperature and keep the energy costs in line.

It should be no surprise that this model is Energy Star certified and it is one of the quietest heat pumps on the market, coming in at 58 decibels.

Pair it with an air handler or variable capacity furnace and it can also remove up to 30% more humidity than a standard single stage heat pump can.


So if the Dave Lennox Signature line of heat pumps sounds appealing don't hesitate to check out the available contractors in your area and ask for the recommendation. Looking at the Lennox heat pumps for residential use, model XP25 is the one that we recommend due to its ultra-high efficiency, quiet operation and top notch features that make it reliable and durable while providing a comfortable climate for less.
