Had our 12-year-old Fujitsu unit replaced with a new Mitsubishi. The difference in efficiency is remarkable — the new unit cools the room in half the time and the energy bills have dropped noticeably. Brilliant service.

Replaced our old single-split with a multi-split system to cover three rooms. Future Smart handled everything from survey to installation. The new Daikin system is fantastic. Highly recommend.

Our commercial AC was 15 years old and constantly breaking down. Future Smart replaced the whole system with minimal disruption to our office. The new system is quieter, more efficient, and has smart controls.

Very professional from start to finish. The engineer assessed our old unit, recommended the right replacement, and the installation was completed in one day. The new Samsung unit is excellent.

Had our old AC replaced with a new A+++ rated unit. The quote was competitive, the installation was clean and professional, and the new unit is so much quieter. Very happy with the whole experience.

Frequently Asked Questions

Everything you need to know about AC replacement in Essex

As a general rule, if your AC is over 10 years old and the repair cost exceeds 50% of a new unit's price, replacement is usually the better investment. Older units are also far less energy-efficient than modern A+++ rated systems, so replacement often pays for itself in reduced energy bills.
A like-for-like single-room replacement typically costs £1,200–£2,500 including installation. Multi-room system replacements range from £3,000–£8,000+. We provide free, fully itemised quotes with transparent pricing and no hidden charges.
In many cases, yes — existing refrigerant pipework can be reused if it's in good condition, which reduces installation time and cost. Our engineer will assess the pipework during the site survey and advise accordingly.
A single-room like-for-like replacement is typically completed in 4–6 hours. Multi-room system replacements take 1–2 days. We aim to complete all residential replacements in a single visit where possible.
Yes — modern A+++ rated units are significantly more efficient than units from 10+ years ago. You could save 30–50% on running costs compared to an older unit. The energy savings often offset the replacement cost over time.
We install all leading brands including Mitsubishi Electric, Daikin, Samsung, LG, Panasonic, and Fujitsu. All are A+++ energy rated with full manufacturer warranties. We'll recommend the best brand for your needs and budget during the survey.
Yes — we safely remove and dispose of your old AC unit as part of the replacement service. All refrigerant is recovered and disposed of in accordance with F-Gas regulations. There's no need to arrange separate disposal.
Please contact us to discuss payment options. We aim to make AC replacement as accessible as possible and can discuss flexible arrangements for larger projects.
