HVAC reviews in Northridge, California

Consummate professionals

on hold forever .................still waiting..

Very good

Only sells to contractor and not to the public.

Fast and great service.

Refused to sell me mineral oil because i wasn't a contractor

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

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

Helpful but only wholesale, or it will be a 5 star for service

They always have what you need , or know where to get it.

really one of the best good service nice personel good price

Not so friendly staff. Didn't care to say hello. Seemed like they couldn't wait for me to leave.

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

Always great service from the guys here !! Yes is a Contractor's store

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.

Very good and fast service , specially Mario. He always helps me out when i go there . Johnstone is very convenient and they supply everything you need for your HVAC/R parts.

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 tell
You 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 or
Maintenance 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 all
Your many years of great service and especially thanks to Mathew..

I have been buying parts from them for past 20 years! YES THEY ONLY DEAL WITH LICENSED CONTRACTORS! THERE IS A BIG SIGN ON THE DOOR! THEY DONT WANT TO BE RESPONSIBLE FOR SOMEONE GETTING HURT! KEEP UP THE GREAT WORK GUYS!!

Not bad team. A lot off for HVAC and beyond.

HIGHLY RECOMMEND!
Ever since Xavier and Sean started working at counter store looks well taken care of and very organized! Love the new look here and always my place to go for all my truck stock!

Xavier went above and beyond to make sure our order was correct. Amazing service! I highly recommend. Thank you!
