Hidden Costs to Be Aware Of

While quotes typically cover standard equipment and installation, extra costs can arise from:

Complex duct routing requiring additional materials or labour
Ceiling or loft modifications for easier access to vents
Electrical upgrades if the existing system is inadequate
Optional features like advanced zoning controls or extended warranties

Energy efficiency: Multi-zone control allows you to heat or cool only the rooms in use.
