Jacob Swei

Managing Director & Lead Engineer

Jacob Swei founded Sub-Cool FM in 2014. He started out working by himself, but in just a few years he had moved on to managing an ever-growing strong compassionate team expanding at an exponential rate by always providing an unbeatable, unrivalled service.

His main obligations & objectives are to ensure Residential customers benefit with lower installations costs over the commercial customer. While doing so setting up an unrivalled neat efficient team to ensure our clients homes & belongings are respected above & beyond.

Jacob believes commercial clients should be given a vast range of installation options without using just the few “favoured brands” by ensuring  we are involved with all the main manufacturers the training provided gives us further industry knowledge to truly provide our clients with a “Bespoke ” service.

He has witnessed first hand over the past 12 years how larger companies carry out a basic standard of work at a premium price, hiding behind their “status”.

Jacob & Sub-Cool FM ensure every job no matter the cost, big or small is carried out above any national standard using longer lasting hard wearing materials the market can offer.
