After reading quite a few old post, reddit and scavenging other forums on internet. I am still in confusion if to buy 5-6 new bldc fans or not. So creating another thread for BLDC fans. 😅
From what I see BLDC has advantage of 35 W compared to 50-52W 1 star normal fans. Recovering their extra cost in an year and then everything after that is profit. But it seems there are too much issues with these fans. there are pcb and new motors in these which if goes kaput after warranty will cost nearly same as the savings you made on electricity and still local electricians are unable to fix these. If you ever face an issue you will have to call service center so there will be visiting charges and wait time of who knows how many days.
Considering that in my scenario there is rarely a electricity cut of even a day its barely few hour and that only in extreme summer of june otherwise nothing, I am not in major city expecting strong and quick service center support, electricity costs average of 4-7 rs per unit and on average my usage is 2 fans 24x7.
To me it doesn't make much sense to have basic necessity like fan to be tied with PCB's and then have another remote just in favor of electricity saving after 1 or 2 years. Also who knows maybe after 2 years solar installation at home would be so cheap and easy that electricity cost won't matter.
So what I want to know based on experience of folks using these, are these future savings really worth the future (and maybe present) headache to deal with these fans.
I think I can just buy normal fans wait for an year if these fans may get even cheaper and the reliability improves I can just exchange my old fans and get them at nearly same price for some rooms.
I have experience with crompton and havells.
They are trouble makers. Stay away. Now i am struggling with crompton bldc which i bought last year june, that came with 5yrs warranty. 5 days back it stopped working and technician came today checked and said Sensor pcb gone and its not covered in warranty, infact it comes with 6 months warranty is what he was telling. He said it will cost me 650/- after taking my old PCB and no service charges.
Man! Its 5200 fan and PCB is what goes bad always and they have only 6 months warranty on it and 5yrs warranty on winding. Ridiculous.
Problems:
Both havells and crompton fans run only on speed 4. Any other speed they slow down and speed up intermittently which will be very annoying.
Our electrician has also taken up automber service and he said most replaced part is PCB.
So my suggestion Stay Away
If someone says i am using it for 3yrs etc, believe his luck but not BLDC.
Buy normal fan and enjoy. I spent 15000 last year on 3 bldc fans and i still regret that all turned the same irrespective of brand 😞
Dont just replace your regular fans to BLDC for power saving
If cuurent one is near end of life, go for it; if setting up new place surely go for it
Yes, using from 3 years. Power saving. Remote access.
