That\u2019s why we\u2019re talking things slower and making sure that we address some more technical terms today. There are a lot of terms thrown around in the industry that you might not understand. We get what it\u2019s like to hear a term thrown around so many times with the assumption that you know what it is that you\u2019re afraid to ask. This is why we\u2019re going to define a common term today\u2014CFM.<\/span><\/p>\n

Why Is CFM Important?<\/span><\/h2>\n

CFM stands for Cubic Feet Per Minute. It\u2019s a term that you\u2019ll hear thrown around when someone is discussing airflow. It\u2019s used to measure the volume of your airflow. This means the CFM itself is determined by how many cubic feet of air pass by a stationary point in one minute. You\u2019ll notice that smaller homes have a lower CFM. This is because the space is smaller meaning that it circulates less air and has a lower CFM as a result.<\/span><\/p>\n

How Is HVAC CFM Calculated?<\/span><\/h2>\n

So maybe you\u2019re wondering why the CFM of a home needs to be calculated at all. Having an accurate estimate of your home\u2019s CFM is integral when you\u2019re trying to choose an HVAC system with the right capacity for your space.\u00a0<\/span><\/p>\n

Why is capacity such a big issue? Too little or too much airflow is going to be an issue. Let\u2019s say that you get an HVAC system with too little capacity, you\u2019re going to have trouble ever getting your system to heat or cool your space properly. On the other hand, you might always think bigger is better, but having a system with an overflow of capacity can cause efficiency issues. You\u2019re likely to run into issues with short cycling and short cycling has disastrous effects. You\u2019ll wind up with a system that costs you more to perform poorly. You\u2019re also going to decrease the lifespan of your system if you allow this to happen over time.\u00a0<\/span><\/p>\n

How Many CFM Do I Need Per BTU?<\/span><\/h2>\n

Now let\u2019s get down to calculations. How many CFM do you need per BTU?<\/span><\/p>\n

The CFM you need per BTU depends on the type of unit we\u2019re talking about (i.e. a furnace versus a central air conditioner) and the size of the space you want to temperature control. This is something that one of our team members would help you determine during a load calculation. It\u2019s why we encourage our homeowners to get a professional involved even during the buying period when they\u2019re looking for a new unit. If you\u2019d like to calculate your home\u2019s specific CFM needs, you can get in touch with one of our professionals today.\u00a0<\/span><\/p>\n
