What they do

Sub-Cool FM is based at Rowfant Business Centre near Crawley, and says it covers the whole of the south-east. It calls Brighton part of its original stomping ground and lists Brighton, Hove, Falmer, Lewes, Worthing and Shoreham. The company was incorporated in November 2015 and has been registered for 10 years.

It does domestic and commercial air conditioning, maintenance and repair, and alternative heating systems. Wall-mounted, floor-standing and ducted units are described, and a Prestonville house in Brighton is on its case studies page with a multi-room Mitsubishi Electric Zen install. Brands named are Mitsubishi Electric, Daikin, Panasonic and Toshiba. Free surveys are offered. Existing Brighton customers include Shandiz, The Plant Room, Bond Street Coffee Shop and Studio Gobo.

Credentials

F-gas: verified on the REFCOM register as Sub-Cool FM Ltd, certificate REF1013926.

Manufacturer approvals: Mitsubishi Electric Diamond Quality Partner and Daikin D1 Business Partner are both verified on the brands' own installer finders. It also says AMP Air-Conditioning and Panasonic recognise it as a Premier Solutions Partner; we haven't checked that on a Panasonic finder, so treat it as claimed.

Company: Sub-Cool FM Limited, number 09877349, active at Companies House. It says it is a Checkatrade member.

Prices and warranty

No prices published; ask for a written quote including units, installation and VAT. The site says it can offer 7 to 10 year parts warranties on the best brands. Specifically: extended warranties of up to 10 years on Mitsubishi Electric systems and up to 7 years with Daikin, which depend on using an approved installer. Ask which warranty applies to the model you are quoted.

Good to know

  • Trading history relies on Companies House and the brand finders. The site footer reads 2017 and its blog has no dated posts.
  • The Brighton page lists a different phone number from the contact page (01293 223 004 against 01293 223 044), so use the contact page number.
  • Registered office (Crawley town centre) differs from its Rowfant base.
  • No prices are published.

Good fit if

  • Mitsubishi Electric or Daikin installs
  • Extended manufacturer warranties
  • Homes and small businesses in Brighton

Maybe not if

  • You want prices published
  • You want a Checkatrade review count

What to ask for in the written quote

  • The make, model and kW rating of each unit. Check the size against our size calculator.
  • What the price includes: pipework, electrics, condensate drain, making good and commissioning.
  • A copy of the company F-gas certificate, and the engineer's certificate number.
  • Warranty on parts and labour, and whether it depends on an approved installer.
  • The survey fee, the start date and how many days the job takes.
