Click here to view our most popular 12,000 BTU System. Because a mini-split system is for cooling and heating, each rating is as important as the other. As the name suggests, the system is ductless, meaning that it doesn’t have ductwork. The minimum SEER rating for air conditioners is 13, while most air conditioners are rated from 13 to 21. Why Buy From a Mitsubishi Electric Contractor.

But there’s a caveat. Sizing an air conditioner or a mini split system is conducted through the so-called load calculation. They do not have the reputation that the more prominent brands have, but they offer reliable mini-split models at lower prices. While the requirements look a bit too much, it’s not as hard to handle as it looks. What would happen if the system is oversized or undersized?

Choosing the right brand is very important, as its reliability is crucial in the HVAC industry. SEER stands for Seasonal Energy Efficiency Ratio, and it measures how energy-efficient the cooling effect of the mini-split is. Mini-splits make less noise as air travels through due to its less turbulent air. They provide a lot of versatility that many other systems don’t have, as it frees up a lot of space usually taken up by ductwork. It is downright impractical because it would not even be able to cool much of the space in your home even if it runs longer. Based on the statement, it follows that a 1-ton air conditioner can remove in a span of one hour an amount of heat that is equal to 12,000 BTUs. The problem is it might undergo a process called short cycling, which is bad. Because of this, the mini-split can be installed virtually anywhere. Mini-split heat pumps, or ductless mini-splits, is a compact heating and cooling system that allows homeowners to control temperatures in homes or individual spaces. The best rule of thumb is to multiply the room size (in sq ft) with 20-30 to get a BTU value… Key Factors to Keep in Mind When Choosing a System for Your Customer.

If the ceiling in the zone you are conditioning is taller than eight feet, ask your HVAC contractor to perform a load calculation using Manual J. This is about 30% more expensive than central air, minus the ductwork. Using an undersized air conditioner to cool a big space would not make any sense. In fact, sizing guides are now very common. On-Premise vs. To determine the appropriate BTU for your customer, you need to figure out each room’s square footage using a mini-split. To err on this aspect will have a huge impact on the level of comfort that you’ll be getting from your mini split unit and the amount of money that you’ll be paying for your energy bill in the long-term. Obviously the right fit is always the best fit. This cycle continues because your system, in this case, is trying to maintain the temperature that you specifically set in the thermostat.
