Nothing says “fun weekend reading” quite like figuring out which quote is the right one to go with. Since ventilation systems can get a little bit technical and quotes are often bespoke to your home, here’s some guidance when looking at alternative options:
Firstly, optimal system design matters – more than the lowest number (of course we’d say this… BUT)
When comparing quotes for a ventilation it’s natural for your eyes to go straight to the bottom line, but behind that final figure are decisions that can shape how your home feels, sounds, and performs for years. At The Air Shop, we believe value is about designing a system that genuinely meets your expectations.
Let’s get into the detail:
Duct size: Small numbers, big impact
One of the most important details to check is duct size. Smaller ducting may look tidy on paper, but it forces air to move faster, creating unnecessary noise and strain on the system. If a design relies heavily on reduced duct sizes, it’s worth considering why. A quieter, smoother system almost always comes from properly sized ductwork that supports healthy airflow rather than restricting it.
Are alternative quotes using the same size ducting?

Are all the right components Included?
Accessories can make or break the performance of your system. Insulated ducting in particular plays a huge role in installed performance – you don’t want condensation forming inside the ducting! When comparing quotes, look closely at what’s included - sometimes a lower price simply reflects missing components that matter down the line.
Is the unit the right fit for the property?
A well-designed system is matched to the home it serves. At The Air Shop, we’ll never design a system to run at 90–100% just to make a design “fit.” On boost mode, nothing should operate above 70% if the system is sized and specified correctly. This ensures longevity, lower noise, and better overall climate control.
Are you comparing a unit which is potentially undersized, appearing cheaper, but will cause nuisance running noise once installed?

Airflow calculations that make sense
Proper airflow isn’t guesswork - it’s measured, balanced, and designed to suit the layout of your property. When reviewing quotes, look for clear airflow calculations or evidence that they’ve been done. They’re the backbone of an efficient, quiet, and reliable system.
Support beyond installation
Whilst not always included in the quote, consider other elements that reflect support around commissioning options, maintenance advice, and a team that’s available when you need them. A system is only as good as the people who stand behind it.
Our approach: Designing for value, not just price
At The Air Shop, our focus is on designing systems that deliver comfort, efficiency, and longevity. We want to meet and exceed your expectations by creating a system that genuinely adds value to your home, not just a price that looks good on paper.
