Air Conditioning Maintenance for Your Nissan: Stay Cool and Comfortable

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​Our Hawaiian summers are fantastic, but you’ll still need the comforting cold air from your AC on a hot day. AC components can wear out or break, and your AC won’t work as efficiently as it should. As your Nissan dealer, we want to tell you about some signs you need to visit us for AC maintenance.

Signs You Need AC Maintenance at Your Nissan Dealer

Cold Air Only at Speed

The speed setting on your dash controls the airspeed of the air blowing into your cabin. A resistor block controls the speed of the AC fans, allowing them to blow faster or slower depending on the speed setting you select. If your AC only blows cold air when you accelerate, then switches to cool air when you decelerate, you probably have a damaged compressor.
The compressor pushes air through the AC and is powered by a pulley that spins as the serpentine belt passes over it. If your compressor is failing, it can’t move air through the system as fast as it used to. When you accelerate, the serpentine belt moves faster, which spins the pulley faster and forces the compressor to work harder. We’ll check your compressor and repair or replace it, depending on the situation.

Noises From the AC

A healthy AC doesn’t make any sound except for the sound of air blowing into the cabin and a tiny click at regular intervals as the compressor switches on and off. Rustling, rattling, clunking, or other strange noises are all signs something is wrong with your AC. Rustling noises are usually made by dirt or leaves that were drawn in through the air intake and are now trapped in the ducts.
Rattling and clunking could mean a more serious issue, as they suggest something metallic is loose. They could be caused by broken compressor bearings or other damaged components. Our technicians can easily remove debris from your AC ducts, and we can also repair any other AC damage, and the noises will disappear.

Fan Problems

Air enters the AC, and the heat and water are removed, then the air is chilled and blown into your cabin. The blower motor controls the fans and blows the air into your cabin. The fan blades are delicate and can easily be damaged by stones or other hard objects thrown up from the road.
Broken or damaged fans will prevent air from blowing into the cabin. A damaged blower motor could also prevent the fans from blowing air. We’ll check your fans and can easily replace damaged ones to restore normal airflow. We can also repair or replace the blower motor if it’s the cause of the problem.
