About Us

About Us

Celcius's experienced engineers in the HVACR industry dates back to 1999 when its founder and director first entered the world of mechanical plumbing and heating, refrigeration, ventilation and air conditioning.

We have undertaken projects for companies in Southampton and across Hampshire, delivering all our services across the south of England. We continue to secure service level agreements with many large, medium and small sized companies, not forgetting the one off and many regular domestic clients we support across the South.

Our commitment to keeping up-to-date with new technologies in air conditioning services, repairs and maintenance has resulted in us being able to advise and assist clients on the most effective and practical route to achieve their systems requirements.

Heat pumps are one of the few technologies that comply with the regulation's efficiency requirements for A+++ class rating which was introduced in 2019.

We are happy to offer advice and information to clients looking to take advantage of energy efficient systems with government backing for the RHI (Renewable Heat Incentive) schemes which we are already providing to our new and existing clients.
