Summer’s coming (as hard as it is to believe right now) and here's an all-to-familiar scenario with the average homeowner: They’re sitting in their house, minding their own business, happily indulging a bowl of popcorn and watching a movie, when all of a sudden – that distant dreadful sound; drip... drip... drip. They glance over to see the household pet licking at a puddle that's gradually forming on the bathroom floor. Suddenly: Anxiety, stress, and that sinking feeling. Where did the leak come from?; water heater, leaky toilet, shower, faucet? Not necessarily – it's the air conditioner of all things. This can occur anywhere, from Edmonton to Timbuktu, regardless of climate.
Why Air Conditioners Freeze
When a central air conditioner freezes up, what actually freezes is the condenser unit's evaporator coil. This component of the air conditioner transfers (evaporates) heat from the inside to the outside of your Edmonton area home. There are two primary reasons the evaporator coil may freeze:
- Restricted air flow
- Low refrigerant
Either way, the ending effect is that the air conditioner's evaporator coil does not properly dissipate heat, and in essence 'overcools' itself. The impact of this super-cooling is condensation (that's water formation), and eventually ice forms from that condensation as it cools below the freezing point. In short, the A/C has morphed into an old-school icebox.
What Might You Do When Your A/C Freezes?
- Turn the unit completely off at the thermostat, and do not increase the thermostat temperature as a way to melt the frost on the coils. It is important that the A/C system is completely OFF.
- Do what you can to ensure airflow is not restricted. Replace the furnace or air handler's filter and replace any return air filters. Open all the registers completely and ensure that they are not blocked by furniture or drapery.
- Call Rob's Albertan Service Experts. The air conditioning system needs to be inspected by a ACE-certified professional to ensure there are no refrigerant leaks or damage to the equipment. Simply schedule a Performance Inspection or Repair Diagnostic online, or call to talk to a live person right away.
What Does it Cost to Repair?
This can turn into a costly repair. When your air conditioner ices over it can lead to damage to the compressor. Replacing your compressor could cost as much as a downpayment on a brand new air conditioner. Unfortunately, many people are forced to decide between installing a new system or repairing the damaged model. If you move fast, follow the instructions, and call a ACE-certified technician, you stand a better chance of getting a less expensive emergency. Your technician will diagnose the situation and how to avoid the issue from occurring in the future. If a leak was really the cause (and that is rare, but possible), the leak has to be repaired or the unit will likely freeze again.
