One question that customers often ask us is whether or not closing vents in unused rooms is a good idea. This article aims to answer that question while additionally supplying a few helpful, energy saving tips.
Can You Save Money By Closing Your HVAC Vents?
Your home heating and cooling systems are not going to work any less just because you close your HVAC vents. As such, you cannot cut your home cooling costs by closing vents. Instead, doing so is going to increase the amount of pressure within the system’s ductwork. This extra pressure can create problems with the air conditioner that can result in extraordinary AC repair costs. The nature of these problems can vary according to the kind of blower motor within your AC system. Among some of the common issues are:
- Increases in energy use
- Increases in duct leakage
- Having your air conditioner coil freeze
- Dead or malfunctioning compressor
- Diminished airflow in the ducts
Therefore, to have an energy efficient central air conditioner you need to keep your vents open.
Different Kinds Of Blower Motors
The blower motor in your HVAC system is an essential component that distributes the conditioned air throughout the building. The blower draws warm air from the building via the return ducts. It also forces cooled air back into the living area via the supply ducts. Blower mowers come in two basic types: PSC or permanent split capacitator and ECM or electronically commutated motors.
The primary difference between these two blower motor types is that the ECM type can alter its speed according to the related workload. A PSC is designed to blow air at a steady or fixed rate instead. Due to this fact, ECM designs are frequently in high-efficiency cooling systems. Conversely, PSC motors are usually present in low-efficiency systems.
How The Performance Of Blower Motors Is Affected By Closing The AC Vents
Both PSC and ECM blower motors function by forcing air against the difference in maximum pressure. More often than not, this difference is 0.5 iwc or inches of water column. But, specific factors can cause a significant increase in the maximum pressure difference. These include narrow supply ducts and dirty air filters. An additional element that might increase this pressure level is the closure of AC vents in rooms that are not in use. In this case, an ECM blower is going to have to work a lot harder to overcome higher than average ductwork pressure. This extra pressure will, in turn, cause more energy use and higher energy costs.
At the other side of the spectrum, PSC blower motors always blow air at a fixed rate. They can’t ramp things up to account for additional pressure within the air ducts. When these motors have to take on additional loads, they merely slow down. Therefore, you aren’t going to get as much conditioned air from the vents that you do keep open. Your home is going to feel a lot less comfortable. Worse still, less air flow throughout your AC system can result in frozen evaporator coils. It can cause extreme damage to the system compressor over time, and this is a very costly component to replace.
Increases In Air Duct Leakage
According to Energy Star, the average US home loses between 20 and 30 percent of its cooled air as the result of duct leaks. Having leaky ducts means that your home is losing cooled air already, and having extra pressure in the ducts is only going to make the issue a whole lot worse. Your AC system is going to end up consuming more energy to cool your home to a level that feels right to you, which translates into increased energy spending.
Is Your Air Conditioner Energy Efficient?
It isn’t possible to save money by closing the AC vents in rooms that you aren’t using. Doing this is not going to change what the blower motor in your cooling system has to do. In fact, opting to close AC vents can cause extra pressure in the ductwork, given that blower motors are built to function at the maximum pressure difference.
Depending upon the type of blower that your HVAC system has, this can create issues like a frozen AC coil, lower airflow, diminished indoor comfort, cracks in furnace heat exchangers, and dead compressors. Thus, it is always better to use other strategies for reducing your home energy use.
