We design and install systems around the rooms, building layout and day-to-day use of the property — not around a one-size-fits-all package.
A practical choice for a bedroom, living room, home office or commercial space. One indoor unit connects to one discreet outdoor unit.
Several indoor units connect to one outdoor condenser, giving separate control across multiple rooms.
A concealed option for larger homes, refurbishments and commercial premises, using discreet grilles.
Tell us which rooms you need to cool or heat, how the property is used and whether the project is for a home, office or commercial space.
We assess room sizes, likely heat loads, suitable indoor-unit positions, outdoor-unit locations, pipe routes, condensate drainage and electrical requirements.
You receive a clear proposal covering the recommended system, installation scope and agreed price. If the scope changes, we discuss it before proceeding.
Our team installs the indoor and outdoor equipment, pipework, drainage and controls, protecting the working area and keeping disruption to a minimum.
We pressure-test, commission and demonstrate the system, including controls, useful settings and straightforward care guidance.
Clear planning at the start prevents expensive surprises later. Here is what is included in our installation approach.
| What matters | Mayfair Plumbers | Typical experience |
|---|---|---|
| Survey before quoting | On-site assessment | Phone estimate |
| System sizing | Room-by-room recommendation | Based mainly on floor area |
| Pricing | Written fixed quote | Estimate can change |
| Electrical work | Planned with the installation | May be left to arrange |
| Handover | Tested, commissioned and explained | Varies by installer |
If an older system is noisy, unreliable, inefficient or no longer suitable for the rooms it serves, we can assess whether repair or replacement is the better long-term option.
Where replacement makes sense, we review the existing pipe routes, electrics, drainage and outdoor position. Some infrastructure may be reusable, but we only retain it when it is compatible and in suitable condition.
Removal of redundant indoor and outdoor equipment
Updated system sizing and layout advice
Options for quieter, more efficient equipment
Testing, commissioning and a clean handover
Tell us about the property and the rooms you want cooled. We will call you back, arrange the right next step and provide a clear written proposal before anything is ordered.
For most installations, yes. A survey lets us check system sizing, unit positions, pipe routes, drainage, electrics and access so the quotation reflects the real scope.
Many modern systems are reversible heat pumps and can provide both. We will explain whether that approach suits the rooms and how you intend to use them.
It depends on the number of rooms, system type, routes and access. A straightforward single-room installation is much quicker than a multi-room or ducted project; timing is confirmed with the proposal.
Often, but the outdoor-unit position, permissions, lease restrictions, access and condensate route must be checked first.
Some drilling and routing are required, but careful planning limits disruption. We explain the proposed route and protect work areas before starting.
