Comparisons
Equipment decisions made against stated criteria: what each option is designed for, what the published specifications say, what the documentation reveals about serviceability, and which reader each option actually suits.
What you can expect here
Criteria before conclusion
The comparison names what it is measuring — capacity, low-temperature performance, controls, parts availability — before it ranks anything.
Specifications, not impressions
Figures come from published data sheets and manuals, with the test standard named, because a US SEER2 number and a European SCOP number are not the same measurement.
Commercial relationships disclosed
Where a link earns a commission, the page says so plainly. Comparisons are not reordered for commercial reasons, and the affiliate disclosure explains the arrangement in full.
Comparisons start once the reference library supports them
A useful comparison depends on knowing how each system fails, not only how it is advertised. These pages publish after the underlying equipment references are in place.
