While choosing a casement window air conditioner, you need to consider factors such as cooling capacity, installation, electrical requirements, energy efficiency, and maintenance needs. Cooling capacity should be the primary consideration. Cooling power is measured in British Thermal Units or BTUs per hour. It is the basic measure of thermal energy.
For the best results, choose a unit with a BTU level suitable for your room’s area. A window AC with too little BTU power will run continuously to cool a large space. In this process, it will consume more energy and will eat up your energy budget. A window AC that’s too large for your space won’t cool and dehumidify your space evenly. Your room air will be susceptible to uncomfortable hot and cold pockets. So, choose the one with the right thermal efficiency. For installation of your casement window air conditioner Window Air Conditioner, seek the help of a qualified contractor.
Make sure that your existing electrical system can support the casement window air conditioner’s electrical requirements. Most room air conditioners operate on 115-, 125- or 220-volt circuits. ACs with cooling capacities below 15,000 BTUs usually run on standard residential (115- to 125-volt) circuits. The electrical requirements such as voltage, amps, and watts will be listed in the specifications when you purchase the unit.
Coming to energy efficiency, The best casement window air conditioners are more economical than central air conditioners. They cost less and cheaper to operate. To gauge a unit’s energy efficiency, consider the Energy Star rating and/or EER number mentioned. The higher the EER, the more efficient the air conditioner will be. Look for the air conditioners that have an EER of at least 10 for the best efficiency and cost saving.
Energy Star-rated room air conditioners use approximately 10 percent less energy. Such air conditioners come with features such as timers, digital thermostats, and multiple cooling speeds. Proper maintenance is essential to keep the air conditioner in top condition. Clean the unit from dirt and dust that accumulate inside or on the back at regular intervals. Clean the dust and particles from the unit’s air filter to keep the unit energy efficient.
