Kitchen Chimney Low Suction Repair in Bangalore
Poor suction has four realistic causes, and two of them are about how the chimney was installed rather than anything that has since gone wrong with it.

Four reasons a chimney doesn't pull smoke, and how to tell them apart
'It doesn't take the smoke away' is the most common chimney complaint. It has four realistic causes, and distinguishing them matters because two are service issues and two are installation issues that no amount of cleaning will fix.
Grease buildup. The most likely cause and the most fixable. Covered in detail on our deep cleaning page -- the short version is that a caked blower wheel destroys airflow while the motor sounds completely normal. If your chimney used to work well and has gradually declined, this is almost certainly it.
Duct problems. This is where installation quality shows. Every bend, every metre of length and every reduction in diameter costs airflow, and flexible aluminium ducting costs considerably more than smooth rigid duct because of its corrugated interior. A chimney ducted a long way with several sharp bends, or through crushed flexible ducting squeezed above a false ceiling, will underperform badly no matter how clean it is. We see ducting that was kinked during installation and never checked since.
The non-return damper. A flap that stops outside air, smells and insects coming back down the duct. It can stick closed with accumulated grease -- at which point the blower runs against a closed flap and moves almost nothing. It can also be fitted the wrong way round, which produces the same result from day one.
Mounting height. There is a correct range above the hob, typically around 65 to 75cm for a gas hob. Mounted too high, the chimney cannot capture the rising plume before it disperses into the room. This is a surprisingly common installation error and it presents exactly as poor suction on an appliance that is working perfectly.
Undersized for the kitchen. Suction is rated in cubic metres per hour, and a unit chosen for its looks or price rather than the kitchen volume and cooking style will never keep up. Indian cooking needs meaningfully more extraction than the same size European kitchen.
Motor faults. Genuinely last on the list. A failing capacitor makes the motor run slow, but the motor is rarely the actual problem.

Kitchen Chimney Low Suction Repair in Bangalore — frequently asked questions.
My chimney used to work well and has gradually got weaker. What is it?
A gradual decline points almost certainly to grease buildup, and specifically to the blower wheel rather than the filters. The motor sounds completely normal while the caked wheel moves a fraction of the air it should.
It has never worked well since installation. What's wrong?
That points to an installation issue rather than a fault -- most often ducting with too many bends or crushed flexible duct, a damper fitted the wrong way round, mounting height too far above the hob, or an undersized unit.
How high above the hob should a chimney be?
Typically around 65 to 75cm for a gas hob. Mounted higher, it cannot capture the rising plume before it disperses into the room, which presents exactly as poor suction on an appliance working perfectly.
Does the ducting really make that much difference?
Yes, a great deal. Every bend, every extra metre and every diameter reduction costs airflow, and corrugated flexible duct costs far more than smooth rigid duct. Crushed ducting above a false ceiling is a common hidden cause.
Could the motor be at fault?
It can be, but it is genuinely last on the list. A failing capacitor can make the motor run slower than it should, but grease, ducting, dampers and mounting height account for the overwhelming majority of suction complaints.
30-day service warranty, on every job.
If the exact same fault returns within 30 days of the visit, we fix it again at no charge — written on your digital bill, not just promised verbally. Any part we replace carries a 6-month parts warranty on top.
