Key comparison criteria
Do not compare models on price alone. The relevant decision factors for this collection include:
- Overview
- product types
- sizing
- efficiency
- durability
- maintenance
- cost
- best applications
Use the total-cost view
Evaluate purchase price together with installation, energy use, routine service, likely repairs, replacement intervals and any supporting equipment the system requires.
Proper load calculations and installation quality can affect comfort and operating cost as much as the product label.
