FAQS About HVAC Systems

By  | 

Are you wondering about the basics of HVAC systems? Do you want to know how to maintain yours or what setting to put it on? If so, you’ve come to the right place. In this article, we’ll answer some frequently asked questions about HVAC systems to help you out. Keep reading to learn more.

Should the fan be set to auto or on?

When it comes to using a thermostat, there is a wide variety of settings available to choose from. One of the most popular and beneficial settings is the fan setting. This setting can be used to help regulate indoor temperature and air quality, making it an important element of any home. So, should fan be on auto or on for heat? In most cases, it’s best to keep the fan set on auto. This allows the fan to run only when it’s necessary to keep the temperature within the desired range. This also helps to conserve energy and prevents the fan from constantly running, which can be noisy and inefficient.

When the fan is set to on, it will constantly run regardless of the temperature. This can lead to an increase in energy consumption and noise levels. This can also result in temperature fluctuations as the fan is constantly running and not just when it’s necessary to keep the temperature in the desired range.

How often should you change air filters?

Your HVAC air filter is responsible for catching and trapping dirt, dust, pet dander, and other airborne particles. If not changed frequently, your air filter could become clogged and dirty. The frequency of air filter changes depends on several factors, such as the type of filter you are using, the size of the HVAC system, and the environment in which it is situated. Generally, most standard fiberglass filters should be changed every 90 days, depending on the environment. More efficient filters, such as pleated filters or high-efficiency particulate air filters, should be changed more frequently. Clean air filters will ensure that your HVAC system runs as efficiently as possible and that you have quality indoor air.

Is seasonal HVAC maintenance important?

Seasonal HVAC maintenance is an important part of ensuring your system is running at peak efficiency. It is important to have your system regularly serviced to keep it running smoothly and ensure that it is still working as it should. Regular maintenance can help to prevent costly and unexpected repairs, as well as increase the longevity of your equipment.

Seasonal HVAC maintenance performed by a professional technician can include tasks such as checking for any signs of damage or wear and tear, lubricating moving parts, and cleaning system components. This can help to ensure that your system is running as efficiently as possible and can help to maintain its performance. Additionally, having your system maintained before the heating and cooling seasons can help to prevent any issues due to changing temperatures.

How can you improve the energy efficiency of your system?



Improving the energy efficiency of your HVAC system can help reduce your monthly energy bills and help protect the environment. Given that your air conditioning can account for as much as 12 percent of your annual energy expenditures, it’s imperative that you ensure energy efficiency. One of the most important steps is making sure your system is the correct size for your home and the climate you live in. An oversized system will cause your energy bills to increase because it will be running more than necessary.

Another way to improve the energy efficiency of your system is to invest in a programmable thermostat, which will allow you to set temperature settings that automatically adjust according to the time of day. Finally, you should consider upgrading your system with high-efficiency components such as a more efficient compressor and fan. These components will help your system run more efficiently and reduce your energy bills over time.

Your HVAC system is essential for the comfort and well-being of your home. Understanding how to use your equipment and maximize efficiency will ensure that your home stays comfortable all year long.
