Gree Vireo vs Senville AURA (18,000 BTU)

The answer

Two current R32 systems aimed at the same buyer: someone hiring a professional who wants high certified efficiency and real cold-weather heating without paying premium-brand prices. The Gree Vireo is the performance line from one of the world's largest AC manufacturers; the Senville AURA is a direct-to-consumer value brand that undercuts on price. Both are 230V professional installs with cold-climate operation. Choose on the numbers in the table below and on price - and trust the certified figures, because both brands' marketing has overstated efficiency versus the AHRI certificate, and we publish the certified number, not the banner.

Side by side

Both are flared, evacuated, 230V installs (not DIY units), so budget the professional labor either way and compare the installed total in the installation cost estimator.

Who each is for

The Gree Vireo buyer wants the performance tier from a manufacturer that builds a huge share of the world's air conditioners - genuinely high certified SEER2 and deep-cold operation. If you want brand scale behind the unit and top-of-value efficiency, the Vireo is the pick. (Gree's own "Livo" line is the cheaper, lower-efficiency sibling - see MRCOOL DIY vs Gree Livo for where the value line lands.)

The Senville AURA buyer wants the lowest name-brand price for a high-efficiency, cold-climate unit and already has an installer. AURA consistently undercuts on equipment cost while still publishing strong certified efficiency and a genuine low-temperature heating floor. Our verification did catch AURA marketing overstating heating efficiency versus the unit's own AHRI certificate - so read the certified numbers in the table, which are what we publish.

The bottom line

These are close competitors for the same job. Let the certified SEER2, HSPF2, and low-temperature ratings in the table decide on performance, then let price break the tie - and don't pay a marketing "up to" number either brand prints. If winter heating is the priority, weigh the published low-ambient ratings most heavily (cold-weather guide).
