And few things are worse than sweltering in the heat as you wait for the HVAC technician to come fix your broken air conditioner, knowing it is going to cost hundreds of dollars to repair. The most common reason for a sudden air conditioner meltdown is frozen pipes and tubes.

Why do Air Conditioners Freeze There are lots of things that can cause your AC unit to freeze. A qualified AC professional can help you find the source of the problem, but it does not hurt to understand how freezing occurs so you can take steps to prevent it.wall mounted air conditioning units montreal Refrigerant Charge: If your AC is running low on refrigerant or the fluid is improperly charged, the system can freeze. wall ac unit 12000 btuLeaks are a common cause of refrigerant problems; daikin split air conditioners modelsthese can occur when moving parts rub together or vibrate over time. Leaks are also likely to be found where fittings and shoulder joints are loose. Only a certified HVAC technician should check refrigerant levels and recharge the system if necessary.

Airflow: Restricted airflow can cause the evaporative coils to get so dirty that they drop to a temperature below freezing. Humidity in the surrounding air then collects and freezes around the coils. If your air filters have not been changed in more than three months, airflow can be significantly reduced; undersized ducts are another common cause of poor airflow. Outdoor Temperature: Running your air conditioner on cool days can cause the unit to freeze up. Most central AC systems are not designed to work properly when outside temperatures dip below 60ºF. How to Prevent Freezing Now that you understand the most common causes of air conditioner freezing, you can take positive steps to prevent problems in the future. Refrigerant Charge: To keep fluid levels functional, contact a qualified professional to perform a thorough test on your system. A technician will be able to look for leaks, repair damaged or weakened parts, refill coolant and make sure you AC is in good working condition.

It is always a good idea to schedule maintenance before peak season to avoid high prices or emergency service charges. Airflow: Change the air filters regularly, usually about every three months or so. This is the simplest, most cost-effective way to ensure your air conditioner does not freeze. If you notice that the AC’s evaporative coils are already dirty, you will need to have them cleaned by a professional. You may be able to vacuum out some of the debris yourself, but some have coils that need to be removed for proper cleaning. Outdoor Temperature: This one is pretty simple; just do not use your air conditioner when the outside temperature is below 60º. Not only will you prevent your system from freezing, but you will also save energy and money on utility costs by just opening the windows on cool days.

In this blog you’ll learn: The differences between these two systems The pros and cons of each How to know which one fits your home’s needs Split air conditioning system What it is: In a split-system central air conditioner there are two parts an outdoor metal cabinet and an indoor cabinet. That’s why it’s called a “split” system. The outdoor cabinet contains the condenser and compressor and typically sits on a concrete slab outside your home.

The indoor cabinet contains the evaporator and is usually located in the attic or a closet. The indoor cabinet also typically includes a furnace (or the inside part of a heat pump). The indoor and outdoor units are connected by a refrigerant line. Here’s a simple diagram of a split system: Greater energy efficiency possibilities - Split air conditioning systems have SEER ratings from 13 to 23. Labor costs - Labor costs more because you are installing a unit outside the house and also inside (usually in the attic or crawlspace, depending on the type of air handler). Also, the system can’t be charged with refrigerant until it has been set in place, which adds to the cost. When you’d want this: It’s a more cost efficient choice if your home already has a furnace, and you are purchasing a new air conditioning unit or replacing an older unit. Learn more about this on Energy.gov’s website. Packaged air conditioning system What it is: The evaporator, condenser, and compressor are all located in one cabinet and thus “packaged” together.

This single cabinet is usually placed on a roof. Some packaged air conditioners can include electric heating coils or a natural gas furnace. That means you won’t need a separate furnace inside. Space efficiency - Unlike split-system units, the package unit has all the components in one place. Cheaper installation - Since packaged units can come pre-charged with refrigerant, and they are only installed outside, installation is cheaper than a split unit. Limited energy efficiency: Packaged units typically have a SEER rating from 10 to 18. A packaged system is ideal for situations where indoor space is limited and therefore important. This is usually the case for mobile homes and homes with a crawl space. The biggest factor to consider is the construction of your home. Most newer homes were built with split central air conditioning because it’s much more cost-efficient to run over time. However, if you live in an older or smaller home or a mobile home, you probably have a packaged unit because of space restrictions.
