Ait conditioning in terraced property

[Blister]

We've decided to finally get this done.
But contrary to the glossy brochures, the first engineer has started talking about trunking...

We need to get more quotes but what are the experience of others around air conditioner installation?

We're not planning to use it for heating in winter, just for cooling on certain summer days.
The bedrooms are more to the front of the house but the living room which is the hottest but most used part of the house is to the back.

I'd like to avoid losing the current lovely lines we have just to be able to sleep for a few weeks in the summer...

And he mentioned humming... is it sleep deprivation levels of bad because that would defeat the entire purpose of the installation?

Our neighbours have it installed (detached) and we've had to ask them not to run it at night. Sounds like a petrol lawnmower being started up every 20 minutes. Not sure if that's all air con or just theirs. Thankfully, they're pretty reasonable about it!

They aren’t the quietest of things from the outside or in my experience anyway. Being in a terrace you also have you neighbours to think of

Walk past or through, any place that has air con. It is not quiet, either inside or outside.

We'll be able to install the condensing units over the extension so the neighbours hopefully won't have the lawn mower humming right next to their walls. But we'll have most of the humming right above us.
I'll look for decibel ratings...

I should check out the running costs before installing it.

What country do you live in? Are the nights very hot?

England. The house was very recently restored. Superbe insulation... Almost all the bedrooms have been at 32+ for a month now. On the worst days this year, we were at 40+ inside the house for 3 days and nights straight... so six days altogether. despite the temp outside being less than 40 at night.
I've lived through harmattans and monsoons and never really felt the need for aircon before...
I think the inland location and the lack of air movement on the worst days make it different.
We've only reached this decision because this is the 3rd or 4th year we've considered it possibly safer to sleep in a tent in the garden..

Your neighbours are saints. I personally wouldn't compromise on this - tropical nights are one of the main reasons I'm currently considering installing A/C. That said, I would go out of my way to find the least noisy system (they exist!)

Have you checked if planning permission is required?

Planning permission would be required for installing a utility? The thought never occurred to me to be honest... I'll check. Thank you.
