Many things can affect how well your HVAC system works, including installation, use, and maintenance. Learn more here about topics that can impact your systems performance.
How does insulation help HVAC?
According to ENERGY STAR, 20 to 30% of air from the duct system is lost because of leaks and holes. Even more, ducting that's either uninsulated or running through unconditioned spaces can lose up to 32% of its effectiveness. This means your system has to work harder to deliver comfort. However, insulation can significantly reduce heat loss in ducts. For example, a 100-degree basement temperature with a 70-degree supply air temperature can result in a 55-degree temperature difference, causing substantial heat loss 
from the uninsulated duct into the basement. Insulation can typically reduce energy losses by 90% and help ensure proper steam pressure for plant equipment.
Why bother clearning my coils?
Your HVAC system uses a series of coils to heat and cool your home. One of those coils is located outside your home and is called the condenser coil. With an outside location, it can get dirty with dust and debris. A dirty condenser coil can reduce its capacity by more than 30% and increase its energy usage by more than 37%.
For example, a three-ton system with a dirty condenser coil is like running a two-ton system, which costs a lot more in energy. The coil inside your home is called the evaporator coil. It absorbs the heat inside your home and also can get dirty, which hinders your HVAC system's performance. That means higher energy bills. Depending on your home's humidity, effects from pollution and pollen, and how dusty your home is, you may need to clean your evaporator coil as well. A best practice is to clean your coils at least annually for optimal HVAC maintenance.
What should you know about IAQ?
Indoor air quality, or IAQ, refers to how clean, comfortable, and healthy the air inside your home is. Many homeowners are not aware of how much indoor air can affect their health, comfort, and even the efficiency of their home. Factors like temperature, humidity, dust, mold, odors, and ventilation all play a role. When these are not in balance, it can lead to issues like dry skin, allergies, musty smells, or poor airflow. Improving your indoor air is one of the best ways to support your family’s well-being and protect your home.
