Troubleshooting Guide for a Frozen AC Unit

AC Unit Frozen Up: What You Need to Know

Hey there, folks! My name is Russ, and I manage the Reliable Appliance & HVAC team here in sunny Santa Monica, California. Today, we’re gonna talk about a problem that’s become all too common this summer: the dreaded frozen AC unit.

So picture this: it’s a hot summer day, temperatures are soaring, and you’ve got your Major Central AC cranked up. But instead of refreshing, cool air, all you’re getting is warm air or none at all. What’s going on?

Well, good news, friends—your trusty Reliable Appliance & HVAC team is here to help! Let me tell you about a recent service call that came in from one of our customers, John Doe from the lovely suburb of Pasadena.

John had been experiencing some issues with his Major Central AC unit. He called us up for some help, and we were there in a jiffy. The first thing our technician noticed was that the unit was covered in frost and ice. Not cool (well, actually, too cool).

What causes an AC unit to freeze up, you might ask? Well, there are a few possible reasons. First, it could be that your air filter is dirty and clogged, restricting airflow and causing it to freeze up. Second, it could be that the refrigerant levels are imbalanced, also causing ice to form. Third, it could be an issue with the evaporator coil or blower fan, causing excess moisture and leading to ice buildup.

After running a diagnostic, our technician determined that John’s issue was caused by a dirty air filter. Once we replaced the filter and gave the coils a good cleaning, John’s Major Central AC was good as new! He was so happy with our speedy and efficient service that he left us a glowing review on Yelp.

But let’s get to the nitty-gritty, shall we? How much did all this cost? Below is a table that breaks down the parts, materials, and labor costs associated with John’s AC unit freezing up:

Item Cost
Air filter replacement $50
Coil cleaning $100
Technician labor $200
Total: $350

Now, we know what you’re thinking—“$350 to replace an air filter and clean the coils? That’s highway robbery!” But let me tell you, friends, that’s actually a fair price for brand name parts and the level of service that we provide.

Our technicians are highly skilled and trained experts who always follow factory recommendations for your brand of AC unit. Plus, we offer a 100% satisfaction guarantee, so if you’re not happy with our work, we’ll make it right. That’s the Reliable Appliance & HVAC difference.

So, what have we learned today, folks? If your AC unit is freezing up, it could be due to a dirty air filter, refrigerant levels, or issues with the evaporator coil or blower fan. When in doubt, call in the experts at Reliable Appliance & HVAC. We’ll have you up and running again in no time.

Thanks for tuning in, folks. Stay cool out there!

Tips to Prevent AC Unit Frozen Up Issues

Are you tired of dealing with a frozen AC unit that stops working every summer? Don’t worry; Reliable Appliance & HVAC is here to help.
Over the years, our technicians have noticed that AC units tend to freeze up when temperatures rise, and the systems have been overused. If you want to avoid AC unit frozen up issues, there are some steps you can take.

Regular Maintenance Checks

First and foremost, make sure to schedule regular maintenance checks with a professional HVAC technician. A trained technician can detect any potential problems that may cause your AC unit to freeze up. Our technicians at Reliable Appliance & HVAC recommend that you call in a professional for a tune-up at least once a year. During the tune-up, our technician will check for any wear and tear on the unit, replace any damaged parts including ductwork, and clean the filters. Regular maintenance checks ensure that your AC unit runs smoothly throughout the hot months, saving you money in the long run.

Keep Filters and Coils Clean

Keeping your air conditioner’s filters and coils clean is also necessary. When dirt and debris accumulate in the unit, they act as a barrier that blocks airflow, causing ice to form on the evaporator coils. The ice prevents warm air from flowing over the coils, which is necessary to cool your home. A dirty filter restricts airflow making the AC unit work harder than it needs to, resulting in a frozen unit. Cleaning the coils and changing the filters regularly can improve the system’s efficiency and help prevent the issue of freezing up.

Thermostat Settings

Another preventive measure to take is to avoid setting your thermostat too low. Tempting as it might be to crank up the AC, doing so can lead to a frozen unit. The warmer it is outside, the more difficult it is for the AC to keep up with the low temperature demands. If you set the thermostat too low, the unit’s evaporator coils will get too cold, leading to a frozen coil. Make sure to set your thermostat to a reasonable temperature that won’t overwork your unit.

Install a UV Light and Dehumidifier

Installing a UV light and dehumidifier can also help prevent the issue of frozen AC units. The UV light in your air conditioner kills bacteria and fungus, which can accumulate on the coils over time. A dehumidifier reduces the moisture in the air, which can cause ice to form on the coils. Both of these preventative measures hold great potential for avoiding AC unit frozen up issues.

In conclusion, regular maintenance checks, keeping filters and coils clean, thermostat settings, and installing a UV light and dehumidifier can significantly contribute to reducing the chance of AC unit frozen up issues throughout the summer months. By regularly performing these simple steps, you can avoid overuse, lower energy costs and enjoy the cool air of an efficiently functioning AC unit.
