Similarities between Carrier and Blue Star AC

Inverter Compressor

Both Carrier and Blue Star ACs utilize inverter compressors that can vary the speed to adjust the power based on the heat load in the room. This results in faster cooling, better temperature control.

Capacity

The capacity of both these 1.5 Ton ACs is suitable for cooling small to medium rooms of 111-150 sq ft in size. The tonnage of 1.5 is ideal for areas that require quick cooling.

Copper Condenser Coil

I have found that both models use 100% copper condenser coils rather than aluminum. Copper coils provide superior cooling, require lower maintenance and are more durable against corrosion.

Ambient Temperature

The ambient temperature range in which these 5 star ACs can operate optimally is quite similar. Carrier AC works till 52°C while Blue Star works till 54°C.

Remote Control Functionality

The remote controls on both Carrier and Blue Star ACs allow you to easily control temperature, cooling modes, fan speeds, on/off timers and other features.

Air Filtration

Good thing I have seen is that both ACs come with advanced air filters like PM2.5 filter to remove microscopic particles, dust, pollen, pet hair etc. This improves indoor air quality.

Self-Diagnosis

Both brands offer self-diagnostic capability in their ACs to detect issues and faults for easy troubleshooting and repairs.

Key Differences between Carrier and Blue Star

Now let’s look at some of the main differences between these two ACs:

01. Energy Efficiency Comparison

During testing I have found, The Carrier AC boasts a high ISEER (Indian Seasonal Energy Efficiency Ratio) value of 5.13 while the Blue Star model has a slightly lower ISEER of 5.02. The ISEER indicates the cooling provided per unit of electricity consumed – higher the value, the more energy efficient the AC is.

Carrier AC has an annual electricity consumption of only 754.05 units compared to 770.98 units of the Blue Star AC as per brand data.

AC ModelISEERBEE RatingAnnual Electricity Consumption
Carrier 1.5 Ton 5 Star5.135 star754.05 units
Blue Star 1.5 Ton 5 Star5.025 star770.98 units

The higher ISEER value combined with lower annual power consumption makes the Carrier AC the clear winner when it comes to energy efficiency. Over years of usage, the savings of over 15 units annually will make a noticeable difference in electricity bills.

02. Stabilizer-Free Operation Comparison

Good thing I have seen, The Carrier 1.5 Ton 5 Star AC can operate smoothly within a 135V to 280V range without needing a separate stabilizer appliance.

The Blue Star 1.5 Ton 5 Star AC has a more limited stabilizer-free operation range of up to 230V. While decent, it is outmatched by the Carrier AC’s superior voltage handling capability.

AC ModelStabilizer-Free Operation Range
Carrier 1.5 Ton 5 Star135V – 280V
Blue Star 1.5 Ton 5 StarUp to 230V

Having a wider voltage tolerance allows the Carrier AC to operate safely during higher voltage fluctuations compared to the Blue Star AC. This can help prevent unexpected shutdowns or damage during unstable power supply.

03. Cooling Comparison

Another interesting thing I have found, Both the Carrier and Blue Star 1.5 ton ACs are evenly matched when it comes to cooling performance making it tough to pick an absolute winner.

The Carrier AC offers maximum cooling capacity of 5760 Watts with normal rating of 5000 Watts. It provides high airflow of 580 CFM, it suitable for quickly cooling small to medium rooms.

The Blue Star AC has marginally lower cooling capacity of 5050 Watts but offers higher air delivery of 637 CFM on max fan speed.

AC ModelCooling CapacityAir Flow Rate
Carrier 1.5 Ton5760 Watts max, 5000 Watts rated580 CFM
Blue Star 1.5 Ton5050 Watts637 CFM max

With 1.5 ton capacity, both air conditioners are ideal for use in rooms of size 111-150 sq ft. Given their similar tonnage and high cooling capacity over 5000 Watts, both the Carrier and Blue Star ACs are competent in providing effective and quick cooling for medium rooms.

There is no clear winner when it comes to the cooling ability of these two AC models.

04. Noise Comparison

The Carrier 1.5 Ton 5 Star AC operates at a low noise level of 38 dB on the lowest fan setting. This goes up to 44 dB on the highest setting.

Comparatively, the Blue Star AC produces slightly more noise of 34 dB on low fan speed but is louder at 49 dB on turbo mode.

AC ModelNoise Level (Low Fan Speed)Noise Level (High Fan Speed)
Carrier 1.5 Ton38 dB44 dB
Blue Star 1.5 Ton34 dB49 dB

This data shows that at lower fan speeds, the Carrier AC is quieter. However, the Blue Star AC produces less ambient noise during higher fan speeds.

The Carrier AC is the winner for its ability to run more silently. But the Blue Star AC takes the lead if you need to use higher fan speeds more often.

05. Smart Features Comparison

Carrier offers innovative 6-in-1 convertible cooling technology; you can customize the AC’s cooling capacity from 100% to 50% as needed. This actually helpful, it can reduce electricity consumption by up to 50% compared to fixed speed ACs.

Good thing I have found, it has auto-cleaning feature, It automatically cleans and disinfects the indoor unit. Useful smart sensors monitor refrigerant levels and room conditions to automatically self-diagnose issues. The wide 135V-280V voltage stabilization also improves performance.

Blue Star cannot match the versatility of 6-in-1 cooling flexibility. But its 5-in-1 modes still allow some customization of cooling as needed. The pre-set high mode helps rapidly cool rooms during peak summers.

The built-in AI algorithm monitors outside and inside temperatures and optimizes cooling accordingly. It also has auto-cleaning and advanced sensor features as seen on Carrier.

Here is a comparison table highlighting the key smart features of both AC models:

FeaturesCarrierBlue Star
Cooling Modes6-in-1 flexible modes5-in-1 pre-set modes
Auto-CleaningYesNo
SensorsLeakage, temp. diagnosticsLeakage, temp. diagnostics
AI CoolingNoYes, built-in algorithm
Voltage Stabilization135V-280VUp to 230V

No one is winner here, both have similar kind of smart features.

06. Maintenance Comparison

Carrier ACs are designed for easy maintenance with conveniently located air filters that can be cleaned in a few minutes. The Auto Cleanse feature also reduces the need for manual cleaning of the evaporator.

Blue Star models have slightly more maintenance needs as their filter placement makes accessing and cleaning trickier. The exterior casing design also leads to some dust accumulation.

Here’s a table summarizing the key differences in maintenance needs:

Auto-CleanYesYes
