Do you want your heat recovery ventilator (HRV) to keep working at peak performance? Then you need to clean it from time to time. It is responsible for keeping your rooms properly ventilated by bringing in fresh air. If you maintain your HRV, then it can also reduce your energy bill. The procedure is quite simple and requires you to complete the following seven steps.
Step 1 – Switch off the HRV
The first essential step should be unplugging the HRV to ensure safety before you start the cleaning procedure.
Step 2 – Clean or change the air filters if necessary
The ventilation efficiency of your HRV will be considerably lowered if you do not keep the filters clean. The rule is to clean them every two months, but even if you cannot do that, you should do it as often as you can. The newer models of HRVs usually have a straightforward procedure for opening the filters, and you can then clean them with a mild soap.
Step 3 – Check if the outside vents are blocked
The outside vents of your HRV need to be unclogged, but they usually get blocked with leaves, twigs and many such items which get blown in by the wind. But you keep an eye out on the vents from time to time and remove all such items are blocking them.
Step 4 – Check the condensate drain
Most of the HRV models have a condensate drain in the form of a plastic tube at the bottom. To clean this drain, all you have to do is pour a litre or two of warm water into it slowly, and the drain will be cleaned.
Step 5 – The heat exchange core has to be cleaned
Every HRV that you buy in Canada comes with an owner’s manual. This manual will tell you about the process to clean the heat exchange core. Vacuuming the core is not enough to clean it. You also need to use soap and water to completely remove all the dirt particles from the core. If you think that it requires a more thorough cleaning, calling a professional is advisable.
Step 6 – Check the ductwork
The ductwork of your HRV needs to be checked at least once a year. You need to remove the grilles that cover the end of the ducts and then inspect them. Then, you can vacuum the ducts. Then again, an HRV technician can do this in a much more efficient manner.
Step 7 – Clean the fans
With time, the fans get covered in dust which slows them down. You need to brush the blades gently in order to remove all that accumulated dust. If you think your fan needs some lubrication, always check the manual before applying the oil to the fan.
