One piece of advice we stress when it comes to heating efficiency and effectiveness is regularly change the furnace air filter. (In most HVAC systems, the AC uses the same filter, so this advice applies throughout the year.) A clean furnace filter is necessary to ensure a furnace doesn’t waste energy, has proper airflow, and won’t collect dust and dirt inside the cabinet that may damage it.
You may not know how to change the filter, but it’s not difficult. Here’s a brief guide to the best practices when it comes to keeping a clean filter.
Many homeowners consider themselves to be handy, and so many people love DIY projects. In fact, there are many websites dedicated to providing homeowners with tips, tricks, and “how-to” projects. However, there are just some skills you can’t master by watching a video or reading a blog. Heating systems are extremely complex, and only a well-trained, experienced HVAC technician can correctly and safely repair your system. Often, doing something yourself can lead to further damage and more hassle.
