How do I make my RX450h air conditioning colder?

Here are a few quick ideas. Shut the passenger air vents and point the other vents directly toward you. Park your car in the shade and use a window sun blocker. Then visit Firestone Complete Auto Care for an A/C performance check and recharge.

Why is my RX450h A/C blowing hot air?

An A/C blowing hot air has several possible root causes. There could be an issue with your compressor clutch, a blown fuse, a leak, or a clog in the expansion valve.

What can cause an A/C system leak?

To put it simply, age and moisture are some of the main causes of leaks in your A/C. Over time, rubber gaskets and seals can wear out, which pushes much-needed refrigerant out of your RX450h’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.

Does running the A/C in my RX450h use gasoline?

Your RX450h’s A/C uses some power from the engine to run. So, while your air conditioning system may not directly use gasoline as a fuel source, using the A/C can indirectly affect your vehicle’s fuel efficiency.

What does it mean if the A/C in my RX450h smells like vinegar?

If a vinegar-like odor comes from your A/C, bacteria growth could be the culprit. Moisture accumulation in the air conditioning system of your RX450h creates a breeding environment for microorganisms.

Why does my vehicle have to be moving for my RX450h’s A/C to work?

There could be issues with one or more components in the air conditioning or electrical system. Your RX450h may have a faulty cooling fan or low refrigerant.

A/C Repair Service for Your Lexus RX450h

When you get in the car on a hot summer day, the last thing you want is a broken air conditioner. Your steering wheel feels like lava. Sweat soaks the driver's seat. You take a deep breath and ask yourself, “Who can fix my Lexus RX450h A/C?” Firestone Complete Auto Care — that’s who! We’ve got experience with Lexus vehicles, and our technicians are qualified to diagnose and repair 2018 Lexus RX450h A/C systems. Steer your Lexus RX450h to your nearest Firestone Complete Auto Care

During this initial A/C performance check, we’ll look at the state of your 2018 Lexus RX450h’s A/C system to determine whether repair work is needed. We’ll test overall system performance, check for any leaks, and measure the system pressure. If any signs point to a possible leak, we’ll send a special U/V dye through the system, or use something called a “sniffer.” A "sniffer" is a machine that's run along parts of your Lexus RX450h A/C system that can identify points where refrigerant fumes could be escaping the system. If your system has a leak, we can get it fixed.

A/C Recharge for Lexus RX450h

Let's say we repair your 2018 Lexus RX450h A/C system. We will also perform an A/C evacuation and recharge. To start this process, a technician will flush out the old refrigerant from your vehicle’s A/C system. Then, they’ll use Lexus’s specifications to evacuate the system. Finally, we’ll recharge the A/C system with new refrigerant and once we’ve done a final test on the system ourselves, you’re good to go. Our technicians know how to keep your A/C in tip-top shape with 2018 Lexus RX450h A/C recharges.

Other Lexus RX450h A/C Problems

Warm air isn't the only Lexus RX450h A/C problem you may encounter. Another common A/C problem is weak airflow, which could be caused by mold or mildew buildup, a loose hose, an old ventilation fan, or a compromised seal. If you notice that your A/C system’s air is cold at first, then quickly goes warm, this may suggest a leak, a blown fuse, or a damaged compressor clutch. What about those (somewhat unpleasant!) smells coming through the A/C vents in your 2018 Lexus RX450h? That could be the result of a dirty cabin air filter (an easy fix!) or a moldy evaporator case. Our technicians will work to solve your A/C problems to the best of their ability. We’re here to help you get back on the road in your RX450h — without all the sweat puddles!
