Signs that Your AC Unit Needs More Freon

Signs that Your AC Unit Needs More Freon: A Guide from Reliable Appliance & HVAC

Howdy! We’re Reliable Appliance & HVAC, and we’re here to help you out with your AC unit. We know how tough it can be to have a broken AC, especially in the summertime. That’s why we’ve put together this guide to help you identify when your AC might be in need of a little TLC.

What is Freon and Why is it Important?

Before we get into the signs that your AC unit needs more Freon, let’s first make sure we’re all on the same page about what Freon is. Freon is a gas that’s used to cool the air in your AC unit. It’s an essential component of most AC systems, and if your unit doesn’t have enough of it, then it won’t cool your house properly.

Signs that Your AC Unit Might Need More Freon

Now that we’ve covered the basics about Freon, let’s get into some of the signs that your AC unit might need more of it.

Your AC Isn’t Cooling Your House Properly

This is probably the most obvious sign that your AC unit needs more Freon. If you notice that your AC isn’t cooling your house as well as it used to, then it’s likely that it’s low on Freon. You might notice that some parts of your house are cooler than others, or that it takes longer than normal for your AC unit to cool your entire house.

Your AC is Making Strange Noises

Another sign that your AC might be low on Freon is if it starts making strange noises. You might hear a hissing or bubbling sound coming from your AC unit, which can be a sign that there’s a Freon leak.

Your AC is Blowing Warm Air

If your AC is blowing warm air instead of cool air, then it’s possible that it’s low on Freon. This can be a little tricky to detect since warm air can be caused by a lot of different factors. However, if you notice that your AC unit is blowing warm air and nothing else seems to be out of the ordinary, then it’s worth having a professional come take a look.

Your AC Coils are Frozen

If the coils in your AC unit are frozen, then it’s possible that your AC unit is low on Freon. This is because the Freon is responsible for absorbing heat from the air, and if there isn’t enough Freon, then the coils can get too cold and freeze.

Signs that Your AC Unit Needs More Freon: Best Practices to Prevent Issues

As residents of San Diego know too well, a properly functioning AC unit can be a godsend in the hot summer months. But what happens when your AC blows warm air, doesn’t cool the house well, or keeps cycling on and off? If you’re experiencing these issues, you may be wondering if your AC requires more Freon.

At Reliable Appliance & HVAC, our technicians are frequently called to perform AC repairs due to low Freon levels. While topping off the refrigerant may seem like a quick fix, it’s crucial to address the underlying issue to avoid future problems. To help you prevent AC issues, we’ve compiled a list of manufacturer and local company recommendations to maintain your AC unit and avoid low Freon levels.

Schedule Regular Maintenance

One of the easiest ways to avoid AC problems is to schedule annual maintenance with a qualified HVAC technician. During a maintenance checkup, a technician will inspect your unit, identify any issues, and perform repairs if necessary. Moreover, regular maintenance can help catch low Freon levels before they cause more significant problems. So don’t wait until your AC malfunctions to schedule maintenance, prevention is the key.

Keep Your AC Filter Clean

Your AC filter is your first line of defense against dust, allergens, and other impurities that enter your home. When the filter becomes clogged, it obstructs airflow and causes the unit to work harder than it should. This overworking can lead to a decrease in refrigerant levels, causing your AC to struggle to cool the house. A dirty filter also lowers indoor air quality, and it can contribute to respiratory issues. So clean or replace your filter on a regular basis, and your AC will work more efficiently, as it should.

Check for Air Leaks

If your home isn’t adequately insulated, it’s possible that cold air is escaping, and hot air is entering your house. This situation causes your AC to work harder than it should, leading to lower refrigerant levels. Check windows, doors, and other areas for air leaks, and seal any gaps or cracks you find. This simple step can go a long way toward maintaining your AC’s Freon levels.

Use Your AC Wisely

Another way to prevent Freon issues is to use your AC conservatively. Turn off your unit when you leave the house or at night when the temperatures are lower. Additionally, you can use ceiling fans or open windows and doors for ventilation when it’s not too hot outside. This step can help you save energy and money while prolonging the life of your AC unit.
