GREAT COUNTER GUYS WHO GET YOU IN AND OUT FAST!!! THANK YOU FOR ALL YOU DO!!!

Not so friendly staff. Didnt care to say hello. Seemed like they couldnt wait for me to leave.

Johnstone Supply has been my only Store for all my Refrigeration and Air Conditioning supplies for the last 20 years, this is because of their friendly and Professional service.

Only sells to contractor and not to the public.

Great place to buy equipment and the sales staff is very friendly and reliable.Matthew the manager has always been a great help and always treat us like we are family.I noticed someone posted about no sign about not selling to Joe Schmo homeowner. That sign has been up for I cannot tellYou how long on the front door/ glass since I was a kid and I’m 46 now.It’s clear as day this is for contractors and orMaintenance professional companies only and that sign is at every location I have visited.Please do not leave a bad review because you cannot simply read or see a very well visible sign as you walk in.Thanks guys at Northridge for allYour many years of great service and especially thanks to Mathew..Robert AdelsonDave Adelson Ac n heat

No where does it say they sell to contractors/businesses only-- No home owners. What a waste of time. Bummer...

Horrible service, especially from the hispanic guy at the front desk, I will never come back again, U should go to a different place
