Define the job and choose a suitable size
Write down what the appliance must do, how often it will run and how long you expect to keep it. For a refrigerator, consider usable storage and household shopping patterns; for a washing machine, normal laundry volume; for an air-conditioner, a competent assessment of the room and heat load. Bigger capacity can raise purchase and operating costs. Buying the largest discounted model is not automatically a more efficient decision for a small household.
Check whether the present problem can be resolved through a suitable repair, correct settings or routine care. A replacement has installation, transport and disposal consequences as well as energy use. If the current machine is unsafe or unreliable, do not postpone necessary action solely to preserve its age record. The aim is a dependable appliance that fits the job, not either replacement or repair as an inflexible rule.
Read the label and verify the exact model
The Bureau of Energy Efficiency’s standards and labelling programme helps consumers compare energy performance. Read the brand, exact model, rated capacity, appliance type, energy figure and label validity period where provided. Star thresholds and methods can change between label periods, so an old five-star sticker and a current three-star sticker do not automatically establish a like-for-like ranking. Ask for a photograph of the label on the actual model being delivered.
Use the official BEE programme or label portal to check the information available for that product category. A promotional webpage, showroom card or similar model number is not sufficient verification. Not every appliance category has the same labelling status or metric, and programmes evolve. Do not interpret an efficient appliance label as a warranty, a safety certificate for every possible use or a guarantee of a particular household’s monthly bill.
Compare the right energy measure for the product
For refrigerators, the label’s annual energy consumption is a useful standardised comparison when type and size are appropriate. Air-conditioners use seasonal performance measures and specified test conditions; the real result depends on weather, room load, installation and settings. Fans may be compared using their applicable performance and power information. Avoid transferring the refrigerator method to every product as though the same printed number has an identical meaning.
Laboratory figures are comparison tools, not exact predictions of use in a particular home. A larger efficient model can consume more total energy than a smaller suitable model with a lower star level. Check the actual energy figure and required capacity together. If a salesperson quotes a percentage saving, ask what model, usage pattern and tariff it is compared with. A claim without a defined baseline cannot support a household budget.
Calculate the annual saving and the efficiency premium
Consider two hypothetical suitable refrigerators with comparable capacity and features. Suppose their label figures are 250 and 180 units annually. The difference is seventy units. At an explicitly assumed avoided energy rate of ₹7 per unit, the annual energy-cost difference would be ₹490. These are teaching numbers, not current product ratings or a tariff recommendation. Actual use and the applicable marginal rate can produce a different result.
If the more efficient option costs an additional ₹3,000, dividing by ₹490 gives a simple recovery period of about 6.1 years. That ignores financing, changing use, maintenance and the time value of money. If the household expects to keep the appliance only three years, the extra price deserves closer thought. Efficiency can still bring benefits, but the arithmetic prevents a modest running-cost reduction from being presented as an immediate cash windfall.
Compare the complete delivered and installed price
Ask for the final price including delivery, installation, accessories, taxes and any necessary electrical or plumbing work. Measure the route through doors and stairs as well as the available space. Follow required clearances and ventilation. For an air-conditioner, clarify the included pipework, mounting, drainage and installation scope. An unusually low base price can become less attractive when essential work is billed separately after delivery.
Check the supply and circuit requirements before ordering a high-load appliance. An adapter or extension board does not replace a suitable rated installation. Ask who is responsible for old-appliance removal and whether exchange conditions can change the price. Photograph delivery damage and record the exact model on the invoice. Where there is a mismatch, obtain resolution through the seller’s documented process rather than accepting a verbal promise to correct the bill later.
Assess service access and the real warranty
Read the whole-product warranty and any separately advertised motor, compressor or component warranty. Clarify labour, transport, consumables, visit charges and exclusions. Ask how service is arranged locally and whether parts are likely to be available through the official route. A long component warranty does not necessarily mean every repair will be free for that entire period. Keep the warranty document and purchase invoice with the model details.
Check which maintenance is required, whether it can be done safely by the user and which tasks need a technician. Assess the ongoing burden of special consumables, proprietary filters or subscriptions where relevant. A product with a low energy figure can still be expensive to maintain. Extended cover should be compared on its terms, duration and claim process rather than added automatically because the checkout screen suggests that declining it is risky.

Compare finance terms and useful features
For an instalment offer, compare the total payable amount with the cash price, including processing fees, interest, taxes on charges where applicable and any discount lost by choosing finance. No-cost marketing does not eliminate the need to read the breakdown. Check repayment dates against the household budget. A future reduction in the electricity bill should not be treated as a guaranteed source for the next instalment.
Choose features that solve an actual need. Remote monitoring may help some households, but extra connectivity creates accounts, support questions and possible dependence on a service. Consider whether the appliance remains useful without its app or subscription. Avoid paying a large premium for functions that will rarely be used. Conversely, accessibility, noise, controls and reliability can justify a modest extra cost even when they do not improve a star rating.
Make a comparison sheet and verify after purchase
Shortlist a few models with the same necessary capacity and list label period, energy figure, complete price, installation requirements, service route and warranty. Add the household’s expected annual usage and a conservative energy-cost estimate. Make uncertainties visible. If the most efficient model is unaffordable, a suitable lower-cost choice used carefully may be the better household decision. Avoid turning the star count into a status competition.
After delivery, verify the exact model, installation and invoice, retain packaging for the applicable return process and learn the essential controls. Check ordinary operation promptly and report faults within the relevant seller and warranty procedures. Record consumption where practical without expecting the first few days to replicate laboratory testing. Arrange responsible reuse or authorised recycling of the old appliance, with any personal data removed from connected equipment.
Readers’ questions
Is five-star always the cheapest appliance over its life?
Not always. The purchase premium, suitable capacity, actual use, tariff, service costs and ownership period all matter. A heavily used appliance may justify a larger efficiency premium than one used occasionally. Compare the same type and label period and calculate a realistic cost difference. The star label is valuable evidence, but it is one part of the complete purchase decision.
Should I replace an appliance before a new label period begins?
A label-period change updates the comparison framework; it does not by itself create a need to replace a functioning product. Decide from safety, performance, repair prospects and realistic operating costs. When comparing stock from different periods, ask for the underlying energy figures and the applicable test method. Avoid buying early or rushing replacement solely because a seller says an older star sticker will soon look worse.
How do I check a claimed annual saving in the showroom?
Ask which exact alternative model is being compared, how many operating hours or standardised units are assumed and what electricity rate is used. Recalculate the difference using your expected use and current applicable tariff. Include the additional purchase and installation cost. If the seller cannot identify the baseline, treat the claim as unverified and compare the label and final quotation directly.
