For radiant heat the company uses Uponor radiant floor heating systems, formerly Wirsbo, in which warm water flows through flexible crosslinked polyethylene (PEX) tubing embedded under the floor. The page notes water can transport energy 3,500 times more than air, so a radiant system can heat using less energy than forced air.
Ductless mini-split systems are presented for homes with no central HVAC system and for additions isolated from existing ductwork, with single-zone and multi-zone options and room-to-room temperature control. Popular locations listed are rooms above a garage, sun rooms and three season rooms, in-law rooms, basements, room additions and home offices. The air conditioners are ENERGY STAR certified and offer up to 24.6 SEER.
The warranty terms above are the equipment manufacturers' published figures. The site does not publish any installation price, labour rate or Assured Air workmanship warranty.

SpacePak high velocity central air installation
SpacePak is a high velocity central air system that Assured Air, LTD. installs, and the company describes itself as a premier installer of it. The SpacePak page explains that the system actively circulates air throughout a building's living space rather than merely dropping cold air in at the ceiling, so there are no cold or warm spots and no drafts, and up to 30% more humidity is removed.
Instead of bulky sheet metal ductwork, SpacePak uses 2 inch mini duct insulated supply tubing. The tubing is seamless so it does not leak, and flexible so it can run behind walls, floors and ceilings with virtually no disruption to livable space or interior architectural features. Outlets are 5 inches in diameter, described as the size of a music CD, and can be placed in the ceiling, wall or floor. Other listed components are sound attenuators, Kwik Connects, flexible ducts, plenum, fan coil unit, return air duct and an optional return air box with PurePak air cleaner.
