During the hot summer months here in Colorado, the last thing that you’ll want to deal with is a malfunctioning AC unit. Unfortunately, there are several potential air conditioner woes that homeowners deal with every summer. One such issue is a frozen AC unit.
It’s undoubtedly strange to see a frozen AC in the dead of summer. But, this issue occurs more frequently than you might think. If your air conditioner is frozen in a block of ice, the problem could be stemming from:
Air conditioners need airflow to function properly. If the unit’s airflow is blocked or inhibited in any way, the temperature of the evaporator coil could fall below freezing. Without proper airflow, humidity can accumulate on the evaporator coil, leading to the formation of ice. Contrary to what you might think, this ice will sabotage the air conditioner’s cooling power, leading to less-than-comfortable temperatures in your Colorado home.
Airflow issues in your Denver AC unit can stem from a variety of factors, including:
- Dirty air filters
We know that you’ve heard it before: It’s important to periodically change or clean your AC unit’s air filters. These filters can get clogged with dust, debris, and impurities. Once the filter becomes clogged, it won’t facilitate airflow to your air conditioning unit, eventually compromising the unit’s functionality.
- Vent and register blockage
If there’s something blocking a vent or register in your home, it will restrict airflow in your HVAC unit. For proper airflow, all of the vents and registers need to be clear.
- Blocked condenser unit
Just like the vents and registers need to be kept clear, the condenser unit can’t be blocked for optimal airflow in your AC unit. Namely for outdoor condenser units, it’s all too easy for obstructions to appear. Whether it be an overgrown shrub or debris that was blown in front of the unit during a storm, anything blocking your condenser unit will compromise airflow for your air conditioner.
- Low fan voltage
Electricity could be behind your HVAC airflow issues. There are several components within your air conditioner that need electricity to function properly. If the fan or blower motor within the unit can’t function properly because of electricity problems, airflow will be inhibited.
- Blower motor damage
Speaking of the blower motor – the blower motor is essential to airflow in your Denver AC unit. If it becomes damaged, airflow to the unit’s coils will stop, creating the risk of freezing.
Refrigerant is a substance in your air conditioner that provides cold air after absorbing heat from your home. As a vital component of your AC system, the refrigerant must be at the right level for the unit to function properly. Low refrigerant levels in your AC will cause the temperature and pressure within the unit to fall. This can lead to an excessively low temperature of the evaporator coil, potentially leading to freezing. Oftentimes, low refrigerant levels are caused by a leak, which could create the need for a Denver AC replacement. But, you’ll need to schedule an inspection with your HVAC experts to find out for sure.
Oversized Unit or Poor HVAC Design
The reasoning behind your frozen AC unit could be simple logistics. All too often, homeowners have an AC unit that’s too large for their homes. If the size of the unit exceeds your cooling needs, it will likely cycle on and off constantly. This can inhibit the unit’s ability to manage the home’s humidity, and excess humidity can lead to a frozen AC.
On the other hand, a poorly designed HVAC system can also lead to AC issues. If the ductwork hasn’t been updated recently, it may not allow for proper cooling, creating the risk of issues like ice accumulation.
