The Ultimate Guide to Air Filter Cleaning for HVAC Systems—Tips and Tricks to Keep Your Home Safe


If you want to keep your HVAC system running smoothly, it is important to regularly change your air filters. Air filters should be changed at least once every three months, but this can vary depending on the type of filter and how often the system is used. It is also important to check your air filter regularly for any signs of dirt or debris build-up, which can reduce the efficiency of your system and cause it to wear out faster than necessary. By following these tips, you can ensure that your HVAC system runs efficiently and lasts longer.




What is an HVAC System & Why You Need to Clean Its Air Filters


HVAC stands for heating, ventilation, and air conditioning. One of the many components of an HVAC system is the air filter, which filters potentially harmful nanoparticles, among other things. When your HVAC system is in use, the air filter traps particles in the filter, and over time the filter needs to be removed from the system so a professional can perform an air filter cleaning. Periodic air filter cleanings are crucial to the performance of your air conditioning system.


How Often Should You Clean or Replace Your Air Filters?


Ideally, you want to clean or replace your air filters every few weeks. The frequency with which you should replace or clean your air filters depends on the pollution you are surrounded by, and the frequency will also be affected by things such as burning candles. Small changes in the air will affect your unit. When your filters are dirty, your HVAC system will have difficulty “breathing,” so the air coming from the system will lessen, and it will need more energy to push air through the filter.


What are the Different Types of Air Filters Available for HVAC Systems?


MERV ratings rank air filters; most HVAC systems will come with MERV-13 filters. You want to have somewhere between MERV 8-10 for residential use. The higher the MERV rating, the more resistant the filter will be. Some design considerations must be considered when upgrading to a MERV filter with a higher rating. We recommend talking to one of our engineers for advice. Most filters in HVAC systems won't need to be replaced but can be washed after removing the filter from the system. Our HVAC technicians are trained to do this to avoid accidental damage to the HVAC system.


Step-by-Step Guide to Cleaning Your Own Air Filters
