Gree Vireo vs Senville AURA (18,000 BTU)

The answer

Choose the Gree Vireo if you mostly need cooling, or if your winters are hard and you want to know how much heat you'll get on the coldest days. Choose the Senville AURA if your winters are moderate and heating costs matter more to you: it's the more efficient heater over a season and comes with the longer compressor warranty. Both are 18,000 BTU systems for someone hiring an installer who wants strong efficiency without a premium-brand price, and both are rated to keep heating down to -22F.

Side by side

Neither is a DIY system. Both need flared lines, a vacuum and a 230-volt circuit, so budget for a professional either way and compare the finished price in the installation cost estimator.

Where each one wins

The Gree Vireo is the better air conditioner, and the one with documented cold-weather heat.

• It's rated noticeably more efficient for cooling, so it costs less to run through a hot summer.
• It keeps its full rated heat down to 17F and still makes about four-fifths of it at 5F.
• Gree is one of the world's largest air-conditioner makers, and its warranty covers units bought online through its own claim process.
• The standard warranty is 5 years on parts and 7 on the compressor; a Gree Select Dealer install can extend both to 10.

The Senville AURA is the more efficient heater, with the better standard warranty.

• Its seasonal heating rating is higher, so it should cost less to heat with through a typical winter.
• Its compressor is covered for 10 years as standard, with 5 years on parts, as long as a professional installs it.
• The catch is the coldest days. Senville doesn't publish the AURA's heat output at 5F, so you can't check how much it keeps in a cold snap the way you can with the Gree.
• Senville sells direct.

The bottom line

Buy the Vireo if cooling is most of the year's work, or if your winters are hard: its cold-weather heat is documented. Buy the AURA for a moderately cold climate where heating costs matter, for its better heating efficiency and longer compressor warranty. Compare the current prices on both model pages, and get installation quotes for both.
