An RV roof unit that rattles, drips or blows warm air on a hot afternoon needs cleaning before it needs parts, and rv air conditioner maintenance starts with the shroud, the coils and the filter. The roof unit pulls outside air across its coils, and dust, leaves and road grime build up on every surface the air touches. This guide walks through cleaning, checking the shroud and covering the unit for winter, with the covers and shroud that fit the work.

RV air conditioner maintenance in short
Clean the shroud and coils, check the filter and the drain outlets, look the shroud over for cracks, and cover the unit when the RV sits unused. Most of the work is cleaning and looking, not parts: a cover keeps leaves and dust out while parked, and a shroud swap fixes a cracked cover. The steps below follow that order, and the gear section names the covers and the shroud that fit the work.
Step 1: Clean the shroud and coils
Switch the unit off at the thermostat and follow the manual before opening anything. Lift the shroud and clear leaves, dust and road grime from the coils and the fan area by hand or with a soft brush, and keep water out of the electrical parts. A shroud that is cracked or brittle should come off for a closer look, since cracks let rain and dust reach the coils. Work from a stable ladder with the RV parked on level ground.
Step 2: Check the filter and the drains
Pull the filter out and hold it up to the light: a filter clogged with dust chokes the airflow and makes the unit work harder. Rinse or replace it as the manual directs, and let it dry before it goes back. Check the drain outlets for leaves and debris, since a blocked drain lets water pool inside the unit. The MQLD covers state that they help keep debris out of drain outlets while the RV is parked.
Step 3: Look the shroud over
Look the shroud over in daylight for cracks, fading and brittle edges. A cracked shroud lets rain reach the parts inside and can rattle loose on the road. The ICON shroud (on Amazon) is a replacement for Dometic Brisk Air (on Amazon) Duo Therm units, with an install the listing puts at 5 minutes and no modifications needed. Match the shroud to the model on the unit before ordering, since shrouds are made to fit specific models.
Step 4: Cover the unit for winter
Measure the unit before ordering a cover: length, width and height across the shroud. The MQLD covers measure 32 by 29 by 15 inches, while the RunNico covers (on Amazon) measure 31.5 by 31.5 by 15 inches, so the sizes are not interchangeable. Pull the drawstring tight at the bottom and set the clinch strap where the cover lists one, so wind cannot lift the cover off. A cover stays on while the RV is parked and comes off before the unit runs.

What this guide does not cover
This guide covers cleaning, checking and covering a roof unit only. It does not cover refrigerant work, electrical repairs or roof installation, and those jobs belong to a qualified technician. For questions about the unit itself, check the manual for the model on the roof.
FAQ: power away from the grid
How often should an RV air conditioner be cleaned?
Clean it when airflow drops, dust shows on the coils or the shroud, or the unit runs longer than it used to for the same cooling. A cover keeps leaves and dust out while parked, so the next cleaning starts from a cleaner unit.
What size cover fits an RV air conditioner?
Measure the unit across the shroud: length, width and height. The MQLD covers measure 32 by 29 by 15 inches, the RunNico covers measure 31.5 by 31.5 by 15 inches, and the ICON shroud measures 35.5 by 29.5 by 10.75 inches. Match the cover to the models the listing names before ordering.
Can an RV air conditioner cover stay on while the unit runs?
No. Covers are for a parked unit that is not in use. Run the unit only with the cover off and the shroud in place, so air can move across the coils. A cover left on while running blocks airflow and traps heat.
Do RV air conditioner covers keep rain out?
They shield the shroud from rain, dust, leaves and sun while parked. The MQLD covers list a PVC coating and Anti-UV coating, and the RunNico covers list a coating against dust, rain, snow and UV damage. No cover replaces a cracked shroud, so check the shroud itself for damage.
When should an RV air conditioner shroud be replaced?
Replace it when it is cracked, brittle or loose, since a damaged shroud lets rain and dust reach the parts inside. The ICON shroud fits Dometic Brisk Air Duo Therm units, with an install the listing puts at 5 minutes and no modifications needed. Match the shroud to the model on the unit before ordering.
