AC unit blowing hot air?

If your ac is blowing hot air, your unit's refrigerant levels may be low. This usually indicates a refrigerant leak in your system! If so, your air conditioner will continue to run and blow hot air, trying to reach the temperature you set on your thermostat.

AC unit not cooling enough?

The most common reason your split and window AC won't cool is because of dirty air filters. If the AC filter is dirty or clogged with dust and dirt, it can lead to various problems. This could interfere with the proper functioning of the thermostat.

Bad Smell coming from AC?

Mold is the most common culprit when an air conditioner smells bad. If you smell musty air coming from your air vents, mold or fungus is growing in or around your air conditioner and can sometimes enter the ducts themselves.

Water leak from AC unit?

A clogged condensate drain is the most common cause of water leaking from your air conditioner into your home. If the drain line is clogged with dust, dirt, mud, or mold, that water will flow back into your home. In this case, you will have to unclog it.

AC Installation Cost

Is there a difference in ac installation cost for residential vs commercial customers in Visakhapatnam?

Absolutely, and it’s not just about the space size. Residential AC installations in Visakhapatnam are typically simpler: a single unit, standard piping, maybe 2–3 hours’ work. These often cost between ₹1,500 and ₹2,500 for split ACs.

Commercial AC installations, on the other hand, involve larger capacity units, more complex wiring, multi-zone cooling, longer piping, duct work, and sometimes night or weekend installs to avoid business downtime. Naturally, this increases labour hours, materials, and setup time.

For Instance :

Time Required	Approx. Cost	Setup Type
2–3 hrs	₹1,800–₹2,500	5 Ton Split (Home)
Full day or More	₹5,000–₹8,000+	Ton Ductable (Office)

At Jayanthi Engineering Works, they handle both types and provide separate cost breakdowns — residential is flat-rate, while commercial is customized based on inspection. They also comply with safety norms for commercial installs, which isn’t always the case with informal technicians.
So yes, there’s a significant difference, and knowing your use case helps you get the right quote and avoid being under- or overcharged.
