Madimack InverEco INVECO400 Heat/Cool Pump
The premium-build budget option (heat-biased) — An Australian-designed reversible inverter with a strong build reputation at about $2,450 — it heats and cools, but its cooling output is modest, so it's the pick for a buyer who mostly heats and wants occasional chill
How to read a Showdown Score™
The only score that counts how often a product breaks, not just how owners feel about it.
- Three parts add up to the score: what owners rate it, how often it fails them, and whether a credentialed tester backed it.
- Bands: Exceptional 8.5 and up, Excellent 7.5, Very good 6.5, Good 5.5, Fair 4, Poor below 4. Every score is dated.
- Price, the warranty and what a link pays us stay out of it.
