I'm looking to buy + install a heap pump in the next month or so and because I know almost nothing about them, I have a few questions :)
What brands generally have the best quietness / power efficiency?
Is a heat pump a waste of time if my roof insulation is a bit crappy and needs replacing?
I'm looking at getting it installed on the second story of my house - will this add much to the installation cost?
Can anyone recommend an installer in West Auckland?
