Overview of Lennox and Rheem Heat Pumps
Lennox is one of the oldest HVAC companies, known for its innovation and the abundance of features in its heat pumps, such as SilentComfort technology. One of the main things the brand excels in is energy efficiency — a major concern for homeowners amidst high electricity costs.
Lennox heat pumps cover three tiers:
- Merit: Budget-friendly heat pumps
- Elite: Mid-range heat pumps with higher efficiency ratings and more features
- Signature: Top-of-the-line heat pumps with industry-leading efficiency ratings and advanced technologies
Rheem, in comparison, is also a respected HVAC name. The brand’s heat pumps often have fewer inclusions, but this depends on the product tier.
Rheem also offers three main product lines:
- Classic: Entry-level heat pumps
- Classic Plus: Heat pumps with higher SEER2 and HSPF efficiency ratings
- Prestige: Heat pumps with premium features and SEER2 ratings often above 20
Energy Efficiency Comparison
Lennox leads in efficiency against most HVAC brands, so it’s not surprising that heat pumps across all its product tiers typically beat Rheem equivalents.
For example, the Lennox SL25KCV — part of the Signature series — has a SEER2 rating of 26 and uses R-454B refrigerant to meet the 2025 EPA regulations for lower global warming potential (GWP) refrigerant.
Most Lennox heat pumps offer slightly better efficiency, while also incorporating technologies like variable-speed operation, lacking in equivalent-tier Rheem products.
Performance and Unique Technologies
Looking at the performance of Lennox and Rheem heat pumps, both offer some excellent technologies to enhance home comfort. Here’s how these brands stack up:
- Noise Levels: Noise depends more on the specific model, but Lennox offers SilentComfort technology, insulated compressors, and a precision-balanced direct-drive fan in most of its advanced heat pumps. Rheem heat pumps feature fewer noise-canceling measures, but select models incorporate the brand’s PlusOne Sound Blanket.
- Advanced Controls: Lennox Precise Comfort technology maintains temperatures within 0.5 degrees of a set point while also offering minute 1% adjustments. Rheem heat pumps feature the brand’s Comfort Control System to optimize temperature control, albeit to a lesser extent.
- Smart Thermostats: Lennox integrates with smart thermostats through iComfort, while Rheem uses EcoNet. Both technologies help you optimize HVAC performance and efficiency, but iComfort offers more features overall. However, EcoNet also integrates with water heaters.
Cost and Warranty
Lennox products tend to be slightly more expensive to install than Rheem products, but the higher efficiency and additional energy-saving features close this price difference over time by reducing running costs.
Warranties for both brands typically cover 10 years on the compressor and covered components for premium heat pumps. This drops to 5 years for budget-friendly systems. However, Lennox also offers premium customer service to help with heat pump upkeep.
Which Heat Pump Is Right for Your Home?
A lot of factors go into choosing the right heat pump, but Lennox offers products for most budgets and preferences. Due to Arizona’s more extreme climate, it’s worthwhile to look at higher-efficiency models in particular. You should also base your decision on noise levels and any specific technologies you’re interested in.
