Even during the hottest days of summer, your air conditioning unit can still freeze up, causing significant issues if it’s not repaired quickly by an AC unit repair team. As one of today’s leading air conditioning installation crews, we’ve seen it a million times. That’s why we wanted to give you some tips on how to avoid having your AC freeze when you need it most.
Dirty Air Filters
One of the most common problems when it comes to freezing AC units is a dirty and blocked air filter. The lack of airflow caused by the filter makes it impossible for cold air to escape your evaporator coils, causing an ice buildup. To fix this, stay on top of changing your air filters regularly.
Low Thermostat Setting
Having an extremely low thermostat setting can increase the likelihood of condensation and ice buildup. If you think this is the case with your air conditioner, running the fan will help melt that ice. However, you may consider cleaning your AC unit and keeping it at a slightly higher temperature for a more permanent solution.
Running Your AC Unit on Colder Nights or During Winter
Air conditioners are great because they help dehumidify the air. However, when you run it during the winter months, you risk having it ice over because of the lower temperatures. Often freezing occurs because there’s not enough warm air present to prevent its evaporator coils from freezing.
Consider investing in a humidifier if this is happening to you; nowadays, some air conditioners come complete with humidifiers. You can also avoid using your air conditioner on frigid days.
Low Refrigerant Levels
Your air conditioner relies on refrigerant to keep air cool, but lower refrigerant levels in your system cause the coils to have extremely low pressure and be more prone to freezing. If you suspect you have low refrigerant levels due to a leak, contact an HVAC technician immediately.

An air conditioner may seem magical – turning electricity into cold air – but it’s actually based on some relatively simple, clever engineering that’s been in use for over a century.
There are only four main components in an air conditioner when it comes down to it, and you’ll see them in any modern AC system, from large standalone units to small mini-splits. Whether you’re considering an air conditioning installation or already own a unit, understanding how it works is always good.
The Most Important Components in Your A/C Unit, And How They Function
In short, air conditioners function by selectively condensing and expanding a refrigerant liquid, which flows continuously through four main components.
1. The compressor
When the refrigerant enters the condenser coil, it’s in the form of warm gas, containing significant amounts of heat energy from the environment. As the name suggests, the compressor coil compresses the refrigerant – turning it into an extremely hot liquid. This process causes the refrigerant to absorb a lot of heat in the environment, capturing it within the AC system.
(This is also the part of the A/C unit which uses the most electricity.)
2. The condenser coil
Once the refrigerant is compressed into a hot liquid, it goes into the condenser coil. Air is blown constantly over the coil, causing the liquid to radiate heat. This heat is then blown into the outdoors, either directly in outdoor units, or via a vent. In this way, it ‘removes’ heat from your home.
3. The expansion valve
This valve is located between the condenser coil and the next stop, the evaporator. The valve’s purpose is to utilize a difference in atmospheric pressure to force the liquid refrigerant to vaporize. In turning into a gas, it loses most of its heat energy and becomes cool.
4. The evaporator
The cool gas passes through the evaporator coils, which are usually made of copper, causing it to become colder. Fans take the cold air produced and blow it into your home. Then the coolant passes back into the compressor and is ready for another cycle.

Are you considering changing how you heat and cool your home? If so, the heat pump sales team from Melton’s Heating & Air Conditioning has collected some important information about one of today’s most reliable heating and cooling solutions: the ductless heat pump.
Below you’ll find everything you need to know about ductless heat pumps and their benefits, so read on!
Why Are Ductless Heat Pumps so Popular?
These days, ductless heat pumps are so prevalent in various homes because they are easy to install and can effectively cool a household without the need to rely on complicated vents and ductwork. They can also decrease your utility bills and efficiently heat/cool specific rooms of your home to whatever specific temperature you would like.
How Do They Work?
Ductless heat pumps require several integral components to work correctly. One of them is the evaporator, a coil that extracts the hot air from indoors and then expels it onto a refrigerant to cool it down—then recirculated when cooled. Condensers are similar to evaporator coils, but instead of releasing cool air, they extract the hot air created from the refrigerant back outside again.
Compressors compress the refrigerant’s pressure and temperature to make it more efficient. It also helps make it easier for the refrigerant to flow through the evaporator coil. Lastly, a ductless heat pump’s expansion valve then helps cool the refrigerant back down to a low-pressure, liquid state.
What Are Some of the Key Advantages of Ductless Heat Pumps?
Some of the leading advantages of ductless heat pumps include:
They take up much less space due to there being no ductwork.
You can easily create multiple heating and cooling zones to maximize comfort.
They’re more efficient than pumps with ducts, in some cases boasting a SEER rating as high as 30.
With the filters present in ductless heat pumps, you can easily control the air quality of your home if you clean them regularly.
