In case you have wondered why your AC is freezing up, this is a useful question to pose. you are not the only one with frozen AC units as this is one of the most requested calls we have taken at Best Florida HVAC. So now, take a deep breath and constantly refer to it as an icebox, let us venture into the reasons why your air conditioner may be becoming an icebox in the first place and what you can do to overcome it.

When AC freezing then it is a problem

When an air conditioner freezes it is a sign that something is interrupting the air flow that is meant to go on the evaporator coil and makes the part to freeze below freezing point. The Florida air is moisture which then is converted to ice on the coil. This may occur because of low level of refrigerant, air flow problem or even a thermostat problem.

In Florida, why does an AC freezes up?

The extreme level of humidity and temperature in Florida provide the ideal setting of AC issues. The following are the best answers as to why your AC can freeze up:

  1. Low Refrigerant Levels
    Refridgerant causes coolness in the air; when it gets low, the pressure reduces hence the freezing up of the evaporator coil. This is usually occasioned by a leakage which requires professional fix up.
  • Dirty Filters or Vents which have poor Airflow
  • The 1st indicator is that the AC units end up freezing as a result of restricted airflow. Blocked duct or clogged filter makes the hot air to stop moving and the temperature of the coil will fall below freezing.
  1. Thermostat Issues
    Your AC may keep running continuously as your thermostat is either on a low setting or some problem occurs in it.

Real Insight 1: Some of my own experiences in the State of Florida

It happened that last summer when we received a call late one night when some homeowner in Orlando called us saying that their AC had frozen up during a heat wave in the month of July. They were switching the filter frequently and turned their thermostat to 60 o F celsius to make the house cool down quickly. That led to continuous use and clogging of ice! Setting the thermostat back to a reasonable setting of 72F was what solved the problem and not destroying the unit of theirs.

The reason that AC Freezing Up Is the Worst in Florida

Due to the high humidity in Florida, the coils with temperature lower than 32 o F form ice quite easily. This is to say that minor airflow or refrigerant problems are to be blamed as reasons behind freeze-ups which when overlooked, will contribute to greater repair.

Real Insight 2: The Way We have assisted a Local Business

Recently we assisted one of the restaurants in Miami that was being visited with frozen AC coils every time they were having dinner time. Their air filters were clean, however ductwork was partially collapsed on one side due to an old roof leak which reduced the flow of air by 50 percent. Fixing their freeze ups in the ducts by replacing the damaged ducts made their freeze ups permanent.

Signs Your AC Is Freezing Up

  • warm or no air blows out of AC
  • Ice on the outdoor or the indoor unit
  • An abnormally high bill when it comes to the energy consumption
  • Leaking of water around the interior unit
  • Short cycling or the constant running
  • Noise murmurs of a leaky refrigerant sounding loudly

Ways of avoiding AC Freezing in Florida

  • Clean or replace your Air Conditioning filters on a monthly basis during summer
  • Don not overcool thermostat by using more than 70 F.
  • The HVAC maintenance should be scheduled on a yearly basis
  • Look out at closed or blocked vents
  • Check drains linings whether clogged or not
  • Check level of refrigerants through a pro

How to Call HVAC Technician

When you notice that your unit has ice and your AC is not cooling, then stop waiting, just switch off the system and request Best Florida HVAC. It is not good to continue operating a frozen AC because it will spoil your compressor and end up on costly repairs.
