What are the steps for cleaning the Mini Split filters myself?

Safety first! Power off the unit. Wear eye protection and a dust mask.

1. Turn off the unit before servicing. Refer to the manufacturer’s instructions for your make and model.

2. Mini splits have 2 filters. Most are located inside the unit behind the front door panel. Most doors swing open from the bottom. Some doors will stay open on their own, some won’t. Use caution when handling these parts because they are plastic.

Some models have filters on the top of the unit, simply locate them and slide them out.

3. You’ll see two mesh type filters in a plastic frame. Remove both filters by lifting the them from the holding tabs on the bottom and slide them down and away from the unit.

4. Vacuum the debris from the filters. For heavily soiled filters, soak and rinse and dry.

5. Reinstall the filters by sliding the top in first, followed by the bottom.

6. Close the unit door.

6. Power up the unit and resume normal operation.

HRV, Air Exchanger Questions

Is home ventilation important?

Why would I want to get my HRV or HVAC cleaned?

Without at least an annual deep clean grease, grime, bacteria and mold affect your air quality. Worse, without this maintenance the product life of your whole HVAC or HRV unit can be reduced. IF you want your system to last you need to get it cleaned!

What does a HRV, Air Exchanger cleaning involve?

Is there a difference between an Air Exchanger, Heat Exchanger, HRV?

Technically speaking yes.

Air exchangers were typically installed in attics and unconditioned spaces. They removed stale air from the home and replaced it with fresh air form the outside. They had no means of recovering heat and were very inafficient, although they did reduce humidity. They no longer meet building code, therefor, are not sold or installed in new construction. Motors can still be purchased and installed in existing units.

Heat Exchangers, HRV’S and Hear Recovery Ventilators are terms used to describe the same thing. Todays heat exchangers have a “Core” inside the unit that is used to recover the heat leaving the home. This recovered heat is transferred to cold air from outsive via the core. and is distributed throughout the home. This cold air meeting a warm core creates condensation in the winter time and is expelled through the drain hose underneath the machine.

Most often, the terms air exchanger, heat exchanger, HRV and heat recovery ventilator are used interchanagably to describe a HRV.

Technically speaking, if it has a drain it’s a Heat Exchangers, HRV/ Hear Recovery Ventilator. If it doesn’t it’s an Air Exchanger.

How often should I clean my HRV, Air Exchanger?

Most manufactures recommend cleaning the filters every three months and core every six months. Professionally cleaning and servicing the system annually is recommended.

Here are some common manufacture brands and links to their information:

Venmar

VanEE

GreenTek

LifeBreath

We already clean our HRV, Air Exchanger filters. Do we still need a deep cleaning?

Yes. Homeowners cleaning the filters and core only meet the minimal cleaning requirements stated by the manufacturer. Our cleaning method ensures the entire HRV, Air Exchanger is cleaned top to bottom and ensures the system is working properly.

The air/enviromental conditions within the home greatly impact how often deep cleaning is required, but typically it’s recommended to have it professionally cleaned and service annually.

The drain line on my HRV, Air Exchanger is dirty. Does it need to be replaced?

The drain line does become dirty with time, this is normal. The drain line should be replaced if it becomes obstructed. Replacements are available.

How long does it take to clean a HRV, Air Exchanger?

Typically, one to two hours.

I already have a HRV, Air Exchanger, why is there still condensation on my windows?

The air exchanger is used to exhaust excess humid air in winter. Therefore, it is normal to see fog or ice on windows during cold weather. Many factors may contribute to this problem, such as: windows poor insulation quality, heating temperature, barrier in front of the windows (lack of ventilation near the windows caused by blinds, curtains, etc.), dominant winds, drastic changes in outside temperature, etc.

Do not wait to heat your home, especially in the basement. It will remove moisture that has accumulated during summer.
