Air conditioning installation in Hastings, St Leonards, Bexhill and across East Sussex should be designed around the room, not just the unit. Optimum HVAC checks room size, sunlight, insulation, noise sensitivity, indoor unit position, outdoor unit access, pipe routes, condensate drainage and electrical supply before quoting.

Single-room and multi-room systems

A bedroom install needs a different layout to a home office, garden room, salon or multi-room domestic system. The quote should explain where each indoor unit will sit, where the pipework runs, how condensate drains and how the outdoor unit will be accessed for maintenance.

Aftercare and repairs

Air conditioning performs better when it is kept clean and serviced properly. If an existing system is blowing warm air, leaking, short cycling or showing an error code, the better route may be air conditioning servicing or repair. Homes comparing cooling with low-carbon heating may also need heat pump installation advice.

What our customers say

“Zak is knowledgeable, detail oriented and does not just a functional but an aesthetically pleasing AC installation. Very happy with the Zak and the work. Zak always kept us informed and updated about everything going on which was very nice. I highly recommended him.”

Satish

“Installed multiple air conditioning units. Zak worked hard in both the design and installation phases to ensure that disruption was at a minimum, and the end result was as unobtrusive as possible. The latter mattered a lot to us, as with a larger install it would be easy for there to be cables all over the place. Zak himself was personable and knowledgeable, and I'm very happy with the end result.”

Jim McDonald

“Thoroughly recommend Zac from Optimum. Knowledgeable, helpful and his work shows his experience. Efficient and cleaned up afterwards, takes pride in his work. Gave solid, honest advice (not just the easy route, the quick fix). See photos of my old hot water cylinder and new.”
