Heat pump servicing and repair in East Sussex keeps renewable heating running properly after installation. Optimum HVAC checks filters, emitters, flow temperatures, controls, cylinder performance, outdoor unit access, error codes and whether the system is delivering enough heat for the property.
Maintenance checks that matter
A good service looks at airflow, weather exposure, cleanliness around the outdoor unit, electrical and control settings, refrigerant symptoms, heating curves and user settings. Small setup issues can make a heat pump feel expensive or underpowered even when the equipment is sound.
When performance needs redesign
If the system was never sized correctly, repair alone may not solve comfort issues. The answer may involve emitter upgrades, control changes, cylinder work or a review of the original heat pump installation. Mixed homes may also need central heating or air conditioning servicing.

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.”
