2020 Most Efficient Heat Pumps
Here they are.
Carrier Infinity 24 with Greenspeed 25VNA4 Heat Pump
Carrier was the first to make a variable capacity split system AC, the Infinity 20, which is still available.
New for 2020 is the Infinity 24 with improved efficiency and variable capacity performance, aka modulating.
This unit is now the most efficient split system heat pump available. Congratulations to Carrier!
Carrier has one of the most solid reliability records of all HVAC brands, along with its sister-brand Bryant.
Efficiency: 24 SEER, 14 EER, 13 HSPF
Performance: Variable capacity and a dual fuel system, meaning it can be used in a system with a gas furnace, though most installations use an air handler. Carrier calls this Hybrid Heat.
Pros: High efficiency and excellent quality. Variable capacity systems also offer the best indoor climate control in all seasons.
Cons: High cost. And in the rare event a variable capacity compressor fails, the repair part is very expensive.
Warranty: 10 years on all parts.
Installed Cost: $5,800 – $11,700
Also Available As: The Bryant Evolution Extreme 284A heat pump is identical. Bryant is a Carrier brand.
Lennox Signature Series XP25 Heat Pump
Lennox makes the most efficient standard split system HVAC equipment available – except for the Carrier model above.
In recent years, the brand has received some bad press for being costly – they still are – but also having repair issues and repair parts supply chain problems. Those concerns have been largely alleviated by Lennox’s aggressive efforts to get its act together.
Efficiency: 23.5 SEER, 15.5 EER, 10.2 HSPF
Performance: Variable capacity heating and air conditioning. It adjusts in increments of about 1%. Here’s a look at how the Lennox XP25 heat pump works. This unit can work in dual fuel systems too – a heat pump and gas furnace.
Pros: Extremely efficient. Excellent comfort control – temperature balance and summer dehumidification. Has all the bells and whistles including WiFi. Here's how it works.
Cons: All that efficiency and performance comes at a higher cost. This is the priciest heat pump on the list.
Warranty: 10 years on all parts. Only average. Brands like Goodman, Heil and Amana have better warranties.
Installed Cost: $6,000 – $12,000 depending on size.
Amana AVZC20 Heat Pump
Amana and its parent company Goodman were purchased by Daikin in 2012, and efficiency and quality have been improved.
Efficiency: 21 SEER, 13 EER, 10HSPF
Performance: Variable capacity, also called modulating or variable speed. It speeds up or down in small increments to maintain balanced temperatures and optimal efficiency.
Pros: Amana uses Copeland compressors, perhaps the brand with the highest quality of any. The compressor is covered with a Lifetime warranty; if it ever fails, Amana will replace the entire condensing unit.
Cons: Overall, Amana is slightly below Carrier/Bryant and American Standard/Trane in overall quality.
Warranty: Lifetime compressor replacement, 10 years on other parts.
Installed Cost: $5,700 – $11,600
Also Available As: Daikin DZ20VC heat pump.

Performance: Variable capacity compressor changes speed in small increments to maximize temperature balance and humidity control.
