How do I make my F-350 air conditioning colder?

For starters, use a sun-blocking shade in the windshield while you’re parked, or look for a shady parking spot. Closing all the passenger vents in your car can help redirect cold air toward you, cooling you off faster. Still need more chill? Head to Firestone Complete Auto Care for an A/C performance check and recharge.

What’s making my F-350 A/C put out warm air?

Maybe your A/C starts cool but then gets warm. Or maybe it never gets cold in the first place. Either way, your A/C troubles could be traced back to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak.

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 F-350’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.

Does my F-350 A/C use gas?

F-350 air conditioning systems don’t use gasoline as a direct fuel source. However, they do rely on engine power, which can indirectly affect your vehicle’s gas mileage.

Why does my F-350 have a vinegary smell coming from the A/C?

If the air conditioning in your F-350 smells like vinegar, it could be due to bacteria growth on system components such as the evaporator and heater cores. Bacteria can grow when moisture accumulates on air conditioning system components, providing a breeding ground for microorganisms.

Why does my vehicle have to be moving for my F-350’s A/C to work?

Damaged or worn components in your F-350’s electrical or air conditioning system can cause the A/C to only work when the car is moving. You may be dealing with low coolant or a faulty cooling fan.

Ford F-350 A/C Repair

There’s nothing worse than cranking your car air conditioner on a hot day — and discovering it’s broken. Is that a hot stove? Nope, just your steering wheel. Sweat soaks the driver's seat. You take a deep breath and ask yourself, “Who can fix my Ford F-350 A/C?” Firestone Complete Auto Care can! We know our way around Ford vehicles, and our qualified technicians can diagnose and service the A/C system in your 1991 Ford. Come to your local Firestone Complete Auto Care in your Ford F-350

During this initial A/C performance check, we’ll look at the state of your 1991 Ford F-350’s A/C system to evaluate what repairs are necessary (if any). We’ll test overall system performance, check for any leaks, and measure the system pressure. If we think there might be a leak, we'll run a special U/V dye through the system or use a "sniffer." A “sniffer” isn’t a technician with a good nose! It’s a machine that’s used on different parts of your Ford F-350 A/C system to detect any refrigerant fumes that might be leaking out from the system. If your system has a leak, we can get it fixed.

F-350 A/C Recharge

When we perform an A/C repair on your 1991 Ford F-350, we’ll also do an A/C evacuation and recharge. To do this, one of our technicians will remove the refrigerant in your A/C system (if there is even any left to remove). Then, they’ll perform an evacuation (also known as a discharge) on the entire system per Ford guidelines. The A/C system is recharged with new refrigerant and once we’ve done a final test on the system ourselves, you’re all set. Our technicians know how to keep your A/C in tip-top shape with 1991 Ford F-350 A/C recharges.

Common Ford F-350 A/C Problems

Warm air isn't the only Ford F-350 A/C problem you may encounter. Typical A/C problems also include weak airflow, which could indicate an old ventilation fan, a seal or hose that needs replacing, or mold buildup in your A/C system. If you notice that your A/C system’s air is cold at first, then quickly goes warm, this can mean there’s a malfunctioning compressor clutch, a leak, or a blown fuse. Are you breathing in some “interesting” new odors in your 1991 Ford F-350? You could have a moldy evaporator case, or you may simply need a new cabin air filter installed. Our technicians will work to solve your A/C problems to the best of their ability. So, chill out. We're here to help you get the blast back in your F-350’s A/C!
