The coils in your HVAC system are vital to its efficient running and you need to keep them clean. Dirty coils can cause a range of problems including higher energy bills, shorter system life, and more system failures. The problem that people face is determining how often their HVAC coils should be cleaned.
How Often Should The Coils Be Cleaned?
The regularity of coil cleaning will vary depending on the system you have and where you live. There are other factors that also impact this which you need to be aware of. It is recommended that you check your user manual for the manufacturer recommended cleaning schedule. This will generally be every 3 to 6 months.
Factors Affecting Coil Cleaning Schedules
There are 3 primary factors that you need to be aware of which impact how often you should clean your coils. These factors will generally result in more regular cleaning being required. It is important to note that you should never leave cleaning your coils for longer than your manufacturer recommends.
The first fact you need to consider is the age of your HVAC system. Older systems are prone to collecting dirt and dust which means their coils need to be cleaned more often. The overall condition of your system also needs to be taken into account with the age. The better the condition of an older system, the less frequently you need to clean the coils.
The second factor is the usage of the system. If your HVAC system is running for many hours every day, you need to clean it more often. If you only use the system sporadically, you will need to clean the coils less frequently. Higher usage introduces more contaminants into the system which can accumulate on the coils.
The last factor is your location. Many people do not consider how location can affect the overall workings of their HVAC system, but this is very important. If you are located in an area with higher pollution levels, around construction sites or a high dust area, you need to clean your coils more often. These environmental factors will increase the accumulation of dust and dirt on the coils because there are more contaminants in the air.
There are other factors that can impact the regularity of coil cleaning such as the make and model of the system. To better understand the needs of your system, you will need to check the manual and the system itself on a regular basis.
Cleaning The Coils
If you have determined that your coils need to be cleaned, it is recommended that you hire a professional HVAC service. Coil fins are sensitive and dust will get between them, but cleaning them incorrectly will damage the coils. Using the wrong cleaning materials can also cause problems which are more expensive to fix than hiring a service.
The regularity of HVAC coil cleaning will depend on a number of factors. The age of the system, your location, and the usage will all play a role. The manufacturer will also recommend a cleaning schedule that you should stick to.
