Choose for the job the appliance will do
Start with your household routine rather than the longest feature list. How much food do you store, how often do you wash clothes, or which room needs cooling? A useful appliance has the capacity, controls and installation requirements that fit your home.
Write down three essentials and a total budget before comparing models. Include delivery, installation and any required changes to the space. Keep optional features separate so a promotional offer does not lead you to buy something larger or more complicated than you need.
Compare exact model numbers, not just brand names or product families. Capacity, energy use, accessories and warranty terms can differ between similar-looking versions. This guide provides a comparison method, not a recommendation for a particular product.
Measure the space and the route into your home
Measure the intended location, doorways, stair turns and lift openings. Check the manufacturer's installation dimensions, including ventilation clearance, door swing, hose space and access for servicing. The appliance's external dimensions alone do not establish whether it can be installed properly.
Confirm the available electrical supply, water connection, drainage and ventilation against the exact model's instructions. Have a qualified installer assess changes where needed. Do not assume an adapter or extension lead makes an unsuitable connection acceptable.
For cooling equipment, have the room and installation assessed rather than choosing capacity solely from a simple floor-area rule. Sun exposure, layout and other conditions can affect the appropriate selection. Ask what installation work and materials are included in the quotation.
- Measure width, depth and height, plus required clearances.
- Check that doors and drawers can open fully in the intended position.
- Confirm the delivery route and who handles stairs or difficult access.
- Identify any electrical, plumbing or structural work before purchase.
- Keep space for cleaning, maintenance and future removal.
Compare features you will actually use
Try the controls where possible and read the manual before buying. Check whether essential functions depend on an app, account or internet connection. If you prefer simple operation, a feature you will never use may add little value.
Check whether advertised accessories are included with the exact model. Ask about consumables such as filters and their availability and cost. Compare noise information only when the measurement basis is comparable, and remember that installation and room conditions can affect what you hear.
| Appliance | Useful comparison points | Question to ask |
|---|---|---|
| Refrigerator | Usable storage, shelf layout, freezer space and door clearance | Will your normal containers fit, and can shelves be cleaned easily? |
| Washing machine | Load capacity, programme options, water requirements and cycle information | Does it suit your usual loads rather than an occasional oversized wash? |
| Air conditioner | Suitable capacity, efficiency information, installation and servicing | Has the actual room and installation route been assessed? |
| Cooking appliance | Usable space, controls, compatible cookware and connection requirements | Can it support the meals you prepare without extra equipment you do not need? |
| Small appliance | Cleaning, storage, replacement parts and useful attachments | Will you use it often enough to justify the space and upkeep? |
Read energy information on a consistent basis
Look for applicable energy labels and model-specific consumption information. Compare similar capacities using the same test basis, programme and units. A star rating from one scheme is not automatically equivalent to a rating from another country or a different appliance category.
The Sri Lanka Sustainable Energy Authority and Sri Lanka Standards Institution publish information about appliance energy labelling. Check the applicable scheme and exact model rather than assuming every appliance uses the same label. Actual consumption also depends on settings, usage, installation and conditions in your home.
Watts describe power, while kilowatt-hours describe energy used over time. For equipment that cycles on and off, multiplying the maximum rated power by every hour it is plugged in can misrepresent consumption. Use suitable consumption data and realistic usage assumptions instead.
Compare purchase price with running costs
Add purchase, delivery, installation, expected electricity use, consumables and servicing over a period meaningful to you. Confirm taxes and any mandatory charges. If paying by instalments, compare the total payable and fees rather than only the monthly amount.
For illustration, assume two otherwise suitable appliances use 400 and 250 kWh per year under comparable conditions. At an invented flat LKR 50 per kWh, the difference is LKR 7,500 annually. This is not a current electricity tariff, a bill forecast or a product specification.
| Illustrative comparison | Model A | Model B |
|---|---|---|
| Purchase price | LKR 120,000 | LKR 145,000 |
| Assumed annual energy use | 400 kWh | 250 kWh |
| Annual energy cost at LKR 50/kWh | LKR 20,000 | LKR 12,500 |
| Five-year purchase plus energy cost | LKR 220,000 | LKR 207,500 |
Check who will support the appliance after purchase
Read the written warranty for the exact model and seller. Identify who provides cover, where service is available and whether registration or authorised installation is required. A long warranty headline may apply only to a particular component rather than the whole appliance.
Ask whether labour, transport, call-out charges and replacement parts are included, and note exclusions. Clarify the distinction between a seller's return policy, a manufacturer's warranty and any separate service plan. Have any important assurance added to the purchase documents.
Ask about the availability of common consumables and service support in your area. For imported, display, refurbished or used units, confirm condition, supplied accessories and the support that actually applies. Do not assume the same model sold elsewhere has identical local coverage.
Plan delivery, installation and the first use
Confirm the delivery date, access requirements, removal of packaging and whether installation is part of the order. Establish who arranges disposal or removal of an old unit. Keep the existing appliance usable until replacement timing is clear where practical.
At delivery, check the model, visible condition and supplied parts against the order. Record damage or discrepancies promptly and follow the seller's reporting process. Keep the invoice, model and serial details, delivery record and warranty information together.
Follow the manufacturer's preparation and first-use instructions, including any requirements after transport. Have required installation completed by a competent professional. Ask for a demonstration of normal operation and essential maintenance before assuming the appliance is ready for routine use.
Your final appliance comparison checklist
Choose the model that fits your home, budget and ability to maintain it. If an essential detail is missing, ask before paying. A simpler appliance with suitable capacity and dependable support can be more useful than a feature-heavy model that is difficult to install or service.
- The capacity and controls fit your regular household needs.
- The appliance fits the delivery route and required installation clearances.
- Electrical, water, drainage and ventilation requirements have been checked.
- You are comparing exact models and included accessories.
- Energy information uses comparable units and realistic assumptions.
- The total price includes required delivery and installation work.
- Warranty coverage, service contacts and any extra service charges are clear.
- Delivery checks, reporting arrangements and first-use instructions are available.
Frequently asked questions
Should I buy the largest capacity I can afford?
Choose around normal use and available space. Extra capacity is only useful if you need it, can install the appliance correctly and can justify its total cost. Compare usable layout as well as the headline size.
Does a higher energy rating always mean a lower bill?
Compare the same type and similar capacity under the same labelling scheme. Actual energy use depends on the model, settings and conditions. A more efficient but much larger appliance may still use more energy overall.
Can I estimate consumption from the wattage alone?
Only with appropriate knowledge of how the appliance operates. Maximum rated power does not show how often equipment cycles or changes output. Prefer suitable energy-consumption data and a realistic usage pattern.
What does a long motor or compressor warranty cover?
Read the written terms. It may cover that component without covering every other part, labour or transport. Ask who handles a claim and which charges or conditions apply to your purchase.
Is installation normally included?
Do not assume it is. Confirm labour, materials, connection work, access charges and any required site preparation. Ask whether authorised installation is a condition of the warranty.
Are display or refurbished appliances worth considering?
Compare their condition, age, accessories, return terms and written support with the price saving. Inspect where possible and record any existing defects. The appropriate choice depends on the exact unit and coverage.
What should I keep after buying?
Keep the invoice, exact model and serial details, warranty terms, installation record and relevant delivery photographs. Store the manual and service contact somewhere easy to find, and note any registration requirement.
