Boiler repairs across East Sussex start with diagnosis, not guesswork. Optimum HVAC looks at the fault code, pressure, leaks, ignition behaviour, hot water symptoms, radiator performance and recent service history before recommending parts or wider system work.
Symptoms worth mentioning before the visit
Send the boiler make and model, photos of any fault code, whether heating or hot water is affected, and whether the pressure keeps dropping. That helps separate a control fault, circulation issue, leak, diverter problem or appliance fault before parts are ordered.
Repair, service or replacement
Some boiler faults are a straightforward repair. Others are a sign that the wider heating system needs attention. If radiators have cold spots or the boiler is being damaged by dirty water, the next step may connect to boiler servicing, central heating upgrades or a planned boiler replacement.

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.”
“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.”
“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.”
