Selecting the right mini split air conditioning system size is crucial for achieving efficient cooling and heating performance. The size of the unit determines how effectively it can regulate temperature without overworking or underperforming. A system that’s too small will struggle to maintain comfort, while one that’s too large may waste energy and lead to uneven cooling.

Technological advancements have made it easier to calculate the ideal size based on the room’s square footage, insulation, and ceiling height. Most systems are rated in BTUs (British Thermal Units), which represent the cooling capacity. For instance, a small room may need a 9,000 BTU system, while larger living spaces might require 18,000 BTU or more.

Modern mini-split systems also come equipped with smart sensors and variable-speed compressors, adjusting performance automatically to meet changing temperature demands. This ensures energy efficiency and consistent comfort throughout the year. Additionally, many units integrate Wi-Fi connectivity, allowing…

Was told to pass this on. He wants a Canadian jet guy to buy it. Hey Guys, For those of you who ever flew at Whidbey, you probably met Brian Richmond. Just got an email from him the other day... He and his son Alex were flying an original Bobcat XL with a Kero Start P120 on it. The P120 has been de-rated to 113k for its entire life, and has something like 25 hours on it. He flew the Bobcat doing rolls on the deck, lots of inverted passes, etc. Anyhow, Brian is moving and wants to unload the Bobcat, and his BVM Sport Shark. He seems to want to sell it all as one for $3kUS, but I'm not sure there's a buyer wanting both, so he'd probably negotiate. He actually let me fly the bobcat once and it's on rails... It once belonged to his brother…
