9) Is it necessary to buy a Voltage stabilizer when buying an AC?
If your AC unit does not come with in-built stabilizer, then it is must to get a Voltage Stabilizer as an AC is a costly home appliance. Therefore it is must to ensure its protection from any possible voltage fluctuation to get the most out of your AC in the long run.
10) Which type of AC consumes less energy? Split or Window
A Split AC consumes less power as compared to a window AC as the split AC’s condenser is bigger, which requires less pressure to discharge the same amount of heat, which overall results in less power consumption.
11) Which type of AC gives better cooling? Split or Window
Again a split AC provides better cooling experience as compared to a window AC as split ACs blow more air resulting in cooling the room more efficiently. Also, Split ACs are meant to cool large rooms while window ACs are a quite good fit for small rooms.
12) What if I use my AC without Annual servicing?
There are several consequences you may face if you use your AC without servicing:
- The condenser may get choked: Increase the chances of compressor failure.
- Choked Filter: Results in bad odor and impure Air
- Electricity Bill increases

Star rating suggests energy efficiency of all electrical appliances. Higher the star ratings lesser will be the power consumption. The highest Star rating of an AC or any electrical appliances is 5, and the lowest is 1.
22) How can I run my AC more efficiently?
These are the following things to run your AC more efficiently are as follows:
- Keep the outdoor unit out of the sun
- Get your AC serviced annually
- Ensure proper insulation of the room
- Clean the filters every two months
- Set the temp between 25°-27° C
- Avoid opening door of the room more frequently
- Avoid switching the AC on and off repeatedly
- Avoid running ceiling fan along with the AC
23) Is it OK for AC to run all day long?
It is not a good idea at all even though it is perfectly fine to run the AC 24 X 7. We will always recommend you to switch off your AC if it is not in use to avoid a massive increase in your monthly bill.
24) How much electricity does an AC consume per day?
If you run a 1.5 TON 5 Star AC for five hours a day, it would cost you around 30₹ per day.
A 1.5 TON 5 Star Split AC consumes 1500 watts per hour.
1 kW/h = 1000 watts/h
1500 watts/h = 1.5 kW/h
For five hours, it would be
1.5 kW/h X 5 h => 7.5 kW
Now, the rate per kW unit is 4.05₹ in M.P (May differ from state to state)
Therefore on a daily basis if you run your AC for 5 hours it would cost you around:
7.5 kW X 4.05 => 30.375 ₹ per 5 hours a day.
And, on a monthly basis, it would be:
30.375 X 30 => 911.25 ₹
Note: You can calculate the same for your AC unit by knowing its power consumption and rate per unit in your area.
25) What happens if AC is not used for 3-4 months?
There will be no issue if the AC is not used for 3-4 months, but try to do one thing before you switch it on for the summer season, “Get your AC serviced before you start”, it will ensure the best performance in the long run.
26) Can I install a different brand AC Indoor and Outdoor units?
Yes, you can, but you have to keep in mind a few things before you make a decision.
- Don’t mix a Non-inverter unit with an Inverter unit and vice versa.
- Both units must have the same TON capacities and refrigerant gas. For example 1 TON Indoor unit goes with 1 TON Outdoor unit.
27) Can I install a Split AC on my own?
No, we do not recommend you to install your AC on your own as long as you are not a professional. It might save you some money in short, but it will cost you a lot in the long run, if the installation is not done properly.
28) What is the Ideal height location for installing an AC?
The ideal height for installing a Split AC is 7 – 8 feet, and for a Window AC, it’s 3 – 4 feet from the floor for the best cooling experience.
29) How quickly an AC cools the room?
If you have the right capacity AC according to your room size, then it will hardly take an hour to bring down the room temperature to 25° – 27° C, which is very comfortable.
30) What is the coldest temperature an AC can achieve?
The coldest temperature an AC can achieve is 16° C, but it is always recommended to keep the AC temperature between 24° to 30° C.
31) Does an AC help you sleep better?
Yes, according to experts, the cool temperature can make you feel sleepy, which overall helps you sleep better. It is also quite difficult to fall asleep if the room temperature is high.
32) Is it healthy to sleep in AC?
Yes, sleeping in AC is absolutely healthy as long as you keep your AC’s filters clean and get it serviced regularly. An AC also improves the quality of air in the room.
33) Does an AC bring in fresh air?
NO, an AC does not bring in fresh air from the outside. Its main purpose is to move out unwanted heat from inside, which results in cooling the room.
34) Does an AC keep the Air fresh?
Yes, an AC keeps the air fresh by removing various indoor allergens, dust and pollen from the air, through its filters results in keeping the air clean.
35) Should I cover my outdoor unit in winters?
No, you don’t need to cover the Outdoor unit in any season as they are built to resist any weather conditions, which elements the need to cover the Outdoor unit.
36) Why does water leak from AC?
It is absolutely normal to leak water from the Outdoor unit of AC in order to prevent breakdowns. Therefore all the condensed liquid is discharged outside and removed through a special tube.
In other cases, if water leaks from the Indoor unit, then it could be a result of improper installation or operation of the AC. It is better to get a professional to troubleshoot the problem.
37) Is it dangerous when an AC leaks?
No, Leaking is not dangerous at all, even if you fill the room full with refrigerant and ignite it won’t catch fire, so there is no need to worry about. It is better to have your AC fixed by a professional as soon as possible.
38) Is it safe to use an Old AC?
No, Old ACs are not safe to use as long as they contain Ozone-depleting refrigerants such as R-22, that is the reason nowadays every new AC comes with Refrigerant gas R-32, which is environmentally friendly.
39) Why is a Split AC placed near the top of the ceiling?
The answer is straightforward, hot air rises up in the room due to low density, when we place our AC at a height it cools down the hot area first, resulting in cooling the room faster and saving electricity.
40) What are the factors that affect AC efficiency?
It is one of the major reasons for the poor efficiency of your AC. Getting your AC serviced at least once a year maintains its high efficiency throughout the years.
If your AC does not breath properly, then it will have to work harder, which directly impacts the performances and efficiency, also it can lead to overheating and breakdown issues of your AC. To avoid this you must clean or change your AC filters within a month or two, also try to keep the area around the outdoor unit clean to maintain a proper airflow around the outdoor unit.
Yes, poor insulation affects the efficiency of your AC. Proper insulation of the room helps the conditioned air to remain cooler for a longer time by preventing the warm air from coming into the room.
Dirty coils reduce the heat transfer efficiency, which results in poor cooling performance, frozen evaporator coils and compressor overheating. Also, it increases the usage of power by 30%, which overall results in poor efficiency.
It is better to get them cleaned by a professional during his service visit, as the fins on the evaporator and condenser coils are extremely breakable, and can be bent over a little force.
41) What are the common issues with an AC?
Below are the common issues you may face with our Air Conditioners:
- Low Refrigerant
- Frozen Evaporator coils
- Dirty condenser coils
- Fan problem
- Dirty Filters
- Not cooling
- Making a strange noise
- Unusual odor
All of the above-mentioned issues can be fixed with the help of a technician. It is always advisable to get your AC serviced at least once a year to avoid any kind of issue with your AC in the long run.
42) How can I turn on my AC without a remote and change temperature?
Well, you can find a power on/off button on your to turn it on and off without a remote. But if your AC is designed specifically for remote control then you can’t change the temperature, it is better to get a universal remote or download a remote app to change the temperature if your AC supports that app.
43) Why does an AC compressor take 4-5 minutes to restart?
Nowadays modern AC generally have a 5 minute time delay for the compressor to start to protect the compressor from burning up as in case if the compressor is itself turned on and off repeatedly due to low refrigerant it can result in drawing high current every time it starts until the compressor burns out or the compressors thermal limit switch is activated. As a solution, a 3-5 minute delay guarantees that the compressor doesn’t burn up.
44) Why should a person not smoke in an AC room?
When the AC is in use, we generally insulate the entire room for better efficiency, in such case if someone smoke the only option remains for the smoke of a cigarette is to stay in the room and mix with room’s air, that we breathe as well, which is more harmful than the smoke present in the open air, that’s why one should not smoke in an AC room. Also, it decreases the lifespan of AC’s filters which prevents dirt and debris from getting into the unit. It is recommended to change or clean the filters once in a month or two.
45) How does an AC work?
An AC cools down the room by exchanging the hot room’s air with cold air, as the compressor (Outdoor unit) condenses and circulates the refrigerant through the outdoor unit by changing it from gas to liquid, later this liquid is passed through the indoor evaporator coil. The indoor unit fan circulates the room’s air to pass across the evaporator fins, later the evaporator’s metal fins exchange the heat with the air around it, at this point the refrigerant turns from liquid into vapour, removing any heat from the surrounding air. As the heat is removed from the air, the air becomes cold and is blown back in the room, resulting in cooling the room.
Now from that point, the condenser (Outdoor unit) turns the refrigerant vapour back into a liquid by removing any heat, and the process is again ready to begin until the room reaches its desired cooling temperature.
46) What is an Inverter AC?
The AC, which features inverter technology, is mainly known as Inverter AC. The inverter technology is the latest evolution of technology in AC, concerning the electromotor of the compressors. The technology is used to control the speed of the compressor motor. Also, it has a variable frequency drive that converts the incoming AC current to DC, and through a modulation it produces a current of the desired frequency, making the inverter AC quieter and efficient with less breakdowns.
Although an Inverter Ac unit is a bit expensive as compared to a non-inverter AC, it will save you a lot in the long run and also it will make itself free of cost within 10 years.
47) What are Pros and Cons of an Inverter AC?
Pros – Inverter AC
High Energy Efficient
It is 40-60% more efficient than a non-inverter AC and environmentally friendly as with inverter technology the compressor doesn’t run constantly at full power; instead, it works at variable speed settings.
It is a lot quieter than a Non-inverter AC as it uses less power and regulates according to room temp.
Overall a good investment
It is more durable than a Non-inverter AC unit, although it is expensive, but in the long run, it will make itself free of cost.
Cons – Inverter AC
It is more expensive than a Non-inverter unit as all the above pros add extra value to the price as well. Also, the parts of Inverter AC are more expensive to replace.
48) What is a Dual Inverter AC?
The usage of two rotary motors by an inverter AC gives it the name of Dual Inverter AC. It provides faster cooling and higher efficiency and longer durability as compared to regular ACs.
49) Which coil is the best? Aluminum or Copper?
Copper coil is better than Aluminum coil as copper has a high heat transfer coefficient than Aluminum which results in faster cooling of room with better efficiency. The copper coil is so much more durable and long-lasting as compared to an Aluminum coil.
50) What are Blue Fins and Gold Fins?
Blue Fins or in other world Blue-coated condenser, and Gold Fin aka Gold-coated condenser, they are used to protect the accumulation of Salt, Acid deposits and Water droplets, overall they protect the condenser coil from corrosion.
Gold Fins are better than Blue Fins as they have higher rust resistance, making the condenser last longer.
51) What is the difference between Rotary and Reciprocating compressors?
Rotary Compressors have two rotors that turn in opposite directions. When Air is trapped between the rotors, they cause compression as they rotate.
Reciprocating compressor uses a piston to compress the air which moves up and down.
Rotary compressors are quieter as the rotors don’t move up and down like pistons resulting in lower dBa than reciprocating compressors. And for the same reason, rotary compressors are more durable and reliable, making them a better choice than reciprocating compressors.
