Senville’s top line makes more than its rated heat at 5 °F, heats to −22 °F and carries a 10-year parts and compressor warranty. Sold online, but the warranty needs a licensed installer.
Amazon $1,499.99Under $2,000 covers most single-zone systems from about 9,000 to 24,000 BTU, including DIY kits with pre-charged line sets that need no refrigerant tools. Higher-end features such as cold-climate heating, quiet indoor units and Wi-Fi are common here but not universal.
Size the unit to the room: an oversized system short-cycles and handles humidity poorly. Check the efficiency rating and the lowest outdoor temperature at which it still heats if you live somewhere cold. Add installation to the price, including the line set length, a disconnect, a pad and any electrical work, since a lower-priced unit can still cost more to put in.
