Frequently Asked Questions
What size AC do I need for my room?
Good question! It depends on the square footage. Generally, 5,000-6,000 BTU is good for a small room (100-250 sq ft), 7,000-9,000 BTU for a medium room size (250-400 sq ft), and 10,000-12,000+ BTU for larger spaces (400+ sq ft). Also, consider factors like sunlight and insulation.
What does SEER rating mean, and which is best?
SEER stands for Seasonal Energy Efficiency Ratio. It’s how well a particular AC converts energy into cooling, like miles per gallon with a car. A higher SEER rating means better efficiency and savings. Look for ratings of 15 or higher!
What are the pros and cons of choosing a portable AC over a mini-split?
Portable ACs are easier to install and move around. They are normally lower cost too! Mini-splits are more efficient, quieter, and offer better long-term cooling, and can heat too! You will have to get a professional to install it and they are not as easy to move around.
How much does professional mini-split installation cost?
Installation cost is a factor. Expect to pay anywhere from $500 to $1500+ for professional installation, depending on the complexity of the job and your location. Get quotes before you decide.
Do these ACs work in very cold temperatures?
Some do! Check for models that specify low-temperature heating, like the ROVSUN or PIONEER models mentioned. They’re designed with features to operate effectively even below freezing. Note their lowest operating temperature.
