Brand
We track 31 Pioneer air conditioner models: 31 mini splits, 9,000 BTU to 35,000 BTU. 25 are in stock at a retailer right now, from $664. We hold no CPSC air conditioner notice that names Pioneer. None of the 27 Pioneer models we track that state a model number is named in a notice we hold, which is not a safety certification. 4 listings state no model number, so check the label on the unit itself.
At each standard size where Pioneer and another brand both have a model in stock, we check whether Pioneer's cheapest model is the cheapest, its best efficiency rating the highest and its quietest verified noise rating the lowest. A price counts as cheaper only by at least $20 and 5%, and only between models installed the same way (a do-it-yourself kit is not priced against an installer-fitted system); anything closer is level. We do not rate reliability: no public data reports repair rates by brand.

Prices are live retailer offers and change often; compare.ac may earn a commission on purchases, at no cost to you. Where one model number is sold as more than one listing, the row shows the cheapest and links the others.
The official Pioneer store says it is owned and run by Parker Davis HVAC International, which registers the Pioneer trademark and describes itself as a manufacturer and supplier of heating and cooling equipment. No source we read names the factory behind a given Pioneer model.

We do not score brands, and no public data reports repair rates by brand. Here is how its in-stock models compare with every other brand's at the same size. For its wall-mounted mini splits: of the 5 sizes compared like for like, its cheapest model is the cheapest in stock by at least $20 and 5% at 2; another brand is cheaper by at least $20 and 5% at 3. Of the 5 sizes where both publish a SEER2 rating, its best rating is the highest by at least 0.5 SEER2 at 3; another brand rates higher by at least 0.5 SEER2 at 2. Where its listings state one, the compressor warranty is 5 years. We hold no CPSC air conditioner notice that names Pioneer. None of the 27 Pioneer models we track that state a model number is named in a notice we hold, which is not a safety certification. 4 listings state no model number, so check the label on the unit itself.

Mini splits: 9,000, 11,500, 12,000, 16,000, 17,000, 18,000, 23,000, 24,000, 31,500 and 35,000 BTU. Match the size to your room with the sizing calculator rather than picking the biggest one.
Yes. The 11 Pioneer mini splits we list whose ENERGY STAR certification we matched can deliver between 71% and 101% of their rated 47°F heat when it is 5°F outside (their maximum output there). By line: Quantum Hyperformance 99% to 101%; Quantum Fresh 77%; Quantum Ultra 71% to 74%; Diamante Pro 73%; Diamante Ultra 73%. All of them carry ENERGY STAR's cold-climate designation. Every certified model's output at 5°F and 17°F is on our page on how cold a mini split can heat.
Mini splits in stock: $664 to $2,118. Prices are live retailer offers and change often.
