What to Do When Your AC Air Handler is Frozen

Hey There, 5th Graders!

Today we’re going to talk about a common issue that arises with Major Central ACs. It’s called ‘Frozen Air Handler.’ And at Reliable Appliance & HVAC, we’ve helped out a lot of people with this problem.

The Definition of Frozen Air Handler:

A frozen air handler is when the evaporator coil, located inside the air handling unit, freezes over because of a build-up of frost or ice. This means that the air conditioning unit won’t work properly and the air coming out of the vents will feel warm.

A Real Life Story:

Picture this, our customer, John Smith, just moved to California and decided to buy a single-family home in LA with a central AC unit installed. It was a hot summer day, and John was looking forward to relaxing in his cool home. But when he turned on his AC, he realized that the air coming out of the vents was warm. He could feel no relief from the hot weather outside.

John had no idea what had gone wrong with his AC, so he decided to give Reliable Appliance & HVAC a call. Our technician arrived fully prepared to diagnose the root of John’s problem.

The technician began the diagnostic process by examining John’s AC unit. After running some tests, he found that the cause of John’s problem was a Frozen Air Handler. The AC’s evaporator coil was completely frozen, which prevented it from cooling the air in John’s home properly.

The technician quickly got to work on fixing the AC, and it was up and running in no time. John was so impressed with the technician’s work that he gave a big shout-out to the manager.

What Caused The Issue?

You may be thinking, why would a Frozen Air Handler happen? Well, there are a few reasons. First, the AC’s air filter may be dirty and clogged, preventing proper airflow. Second, the refrigerant level may be too low, leading to abnormal temperature changes. Third, the thermostat may be malfunctioning or set to an incorrect temperature.

What Our Technician Does

Our technician thoroughly examines the AC for any problems. If we find a Frozen Air Handler, we tackle it right away to prevent any further damage to the AC unit.

Our technician first turns off the AC unit to thaw the AC parts that have frozen, including the evaporator coils. After it thaws, our technician cleans the AC to remove dirt and debris that may cause a Frozen Air Handler in the future.

How Much Would It Cost You?

You may be wondering, how much would this cost? Let’s use John Smith as an example. With all parts and labor included, the cost for the repair was $800. We always use brand name parts, following the manufacturer’s guidelines, and always quote the customer beforehand so that they fully understand the costs.

In Conclusion…

At Reliable Appliance & HVAC, we hope this story has helped explain what a Frozen Air Handler is, what happens when it occurs, and why it occurs. If you ever have any issues with your AC unit, like John Smith, give us a call! We’ll have one of our highly skilled technicians out to you in no time to fix the problem.

What You Need to Know About Preventing Frozen Air Handlers

An air handler is an integral part of an air conditioning (AC) system, and it helps to ensure that the air conditioning unit works effectively. However, one of the most common problems that can arise with an air handler is its ability to get frozen, which can lead to many issues such as inefficiency, increased energy consumption, and even damage to the unit in some cases.

When it comes to preventing the issue of Frozen Air Handlers, there are a few recommendations to follow. Here are some manufacturer and local appliance companies’ suggestions that can help you avoid the problem.

Keep Your AC Filter Clean

One of the primary reasons why an air handler freezes up is that it is not receiving enough airflow. A dirty or clogged AC filter can significantly restrict the airflow, leading to the freezing of the air handler. As such, it’s crucial to keep your AC filter clean by regularly replacing or cleaning it to maintain proper airflow.

Ensure Your Ductwork is Properly Installed

Another critical factor in preventing an air handler from freezing up is the proper installation of ductwork. If your ductwork is installed incorrectly, it can cause the unit to receive too much air, and the cooling coils will get excessively cold, leading to freezing. It would be best to have a professional HVAC technician like our Reliable Appliance & HVAC technicians inspect your ductwork to ensure it is correctly installed.

Check Your Refrigerant Levels

The refrigerant in your AC system plays a crucial role in transferring heat from the air in your home to the outdoor unit. If the refrigerant levels are too low, this process can’t happen correctly, and the air handler might freeze up. You must have your refrigerant levels checked regularly by a Reliable Appliance & HVAC technician to ensure it’s at the optimal levels.

Install an Automatic Defrost Sensor

If your air handler still freezes up even after following these recommendations, it would be best to install an automatic defrost sensor. The defrost sensor periodically checks the unit’s coils and shuts off the system if they begin to freeze up, allowing them to defrost and preventing further damage to the unit.

In conclusion, ensuring proper maintenance and installing an automatic defrost sensor or asking the Reliable Appliance & HVAC technician can offer immense benefits in preventing Frozen Air Handler issues.

FAQ: What to Do When Your AC Air Handler is Frozen and Frozen Air Handler

Q: What is an air handler, and why does it freeze?

An air handler is a part of your air conditioning system responsible for circulating air throughout your home. When it freezes, it means that the evaporator coil is not functioning correctly, and the condensation that has frozen on the coil is creating a layer of ice.

Q: What causes a frozen air handler?

A frozen air handler can typically be caused by one of three things:
– Poor airflow – This can be due to a clogged air filter, dirty coils, or blocked ducts.
– Low refrigerant levels – If you have low refrigerant levels, it can cause the evaporator coil to get too cold and freeze.
– Thermostat issues – If your thermostat is not functioning correctly, it can cause your air handler to freeze.

Q: What are the signs of a frozen air handler?

Some common signs of a frozen air handler include:
– Warm air coming out of your vents
– Reduced airflow
– A buildup of ice on your unit or around your AC system
– Strange noises coming from your AC system
– A spike in your energy bills

Q: What should you do if you notice your air handler is frozen?
