How to Choose a BLACK+DECKER Window Air Conditioner
Size the Unit to the Room
ENERGY STAR publishes this general guide for sizing a room air conditioner by floor area:
| Room Size (sq ft) | Cooling Capacity (BTU/hr) |
|---|---|
| 100 to 150 | 5,000 |
| 150 to 250 | 6,000 |
| 250 to 300 | 7,000 |
| 300 to 350 | 8,000 |
| 350 to 400 | 9,000 |
| 400 to 450 | 10,000 |
| 450 to 550 | 12,000 |
| 550 to 700 | 14,000 |
| 700 to 1,000 | 18,000 |
Reduce capacity by 10 percent for a heavily shaded room, increase it by 10 percent for a very sunny room, add 600 BTU for each regular occupant beyond two, and add 4,000 BTU if the unit cools a kitchen. Source: ENERGY STAR.
Mechanical or Remote Control
The 5000 BTU model uses on-unit controls only. Every larger BLACK+DECKER unit includes a full function remote with sleep mode, energy saver and a 24-hour timer.
Measure Your Window First
Check the width and height of the window opening against the range in each listing, and make sure the sill can carry the weight. Conventional units are built for double hung windows that slide up and down. Casement and sliding windows need a different type of air conditioner.
Consider Noise for Bedrooms
Many listings give a decibel figure for the low fan setting. Inverter units and models with a sleep or mute mode are the quietest choice for bedrooms, while louder units are fine in a kitchen or living room.
Read the Warranty
Most window units carry a one year warranty, but some brands add longer coverage on the compressor or the sealed system. Check whether the extra years cover labor or parts only, and register the unit after purchase.
How We Evaluate BLACK+DECKER Window Air Conditioners
We rank window air conditioners on manufacturer specifications, listing details and aggregated buyer ratings. For a single-brand guide we picked different models from the brand’s current line, one per size or feature class, and left out color and bundle variants of the same unit, portable models, renewed listings and listings with too little data. We weighed cooling capacity against room size, efficiency features and the size of each rating base first, then compared noise, controls, installation fit, power needs and warranty.
Frequently Asked Questions
What warranty do BLACK+DECKER window air conditioners have?
The listings give 1 year of labor and parts for manufacturing defects and a total of 5 years on compressor parts only.
Are BLACK+DECKER window units quiet?
They are standard rotary units. The listings rate the larger models at 60 dB or more, so they are best for living areas.
Does the BLACK+DECKER 14,300 BTU unit need a special outlet?
No. It runs on a standard 115V outlet. The 18,000 BTU model needs 230V.
