Start with the room, not the brand

The single biggest mistake we see is picking a unit based on brand loyalty or the special at the store. The size of the room, its ceiling height, its sun exposure, and the number of windows determine the cooling capacity you need. A unit that is too small runs constantly and wears out. A unit that is too big cycles on and off, which wastes power and leaves the air feeling clammy.

Inverter or non-inverter?

Inverter systems adjust their compressor speed to match demand. That means they use less electricity once the room reaches the set temperature. For rooms used daily, an inverter pays for itself in a few seasons. For guest rooms or rarely-used spaces, a non-inverter may be the smarter buy.

Placement matters more than people think

Indoor units should be positioned where cool air can circulate freely, not directly above a couch or bed. Outdoor units need airflow around them and should be shielded from direct afternoon sun where possible. Cable and pipe runs should be short and neat.

Install with someone qualified

Cheap installations are expensive in the long run. Poor flare joints leak refrigerant. Sloppy drainage causes water damage. Undersized cabling trips breakers. Ask for a written quote that lists the copper size, drain route, and warranty terms.
