When ever the weather heats up we get a lot of air conditioning service calls. The common complaint is, “I can hear the air conditioner turn on but no air is coming out.” That’s because coil inside the AC unit is frozen. One reason for AC freeze-up is that the air flow coming into or out of your system is blocked at some point. You see the air conditioner operates when free flowing air passes through the inner components of your air handler, is cooled by the refrigerant filled coils, and then blown out into your living space.
When air is cooled condensation occurs.
Just like air produces condensation when it comes in contact with the outside of a cold glass, central AC units can generate around 20 gallons of water per day. If the air doesn’t move through the system properly, water can build up on the coil and freeze. More and more condensation will build up and freeze until your coil becomes a solid block of ice.
Here is what to do:
1. Turn the AC off
Nothing can be done until the ice melts, usually around 24 hours. Call and let us know that you need a service call at 818-780-0701. Once your AC defrosts we will be able to repair the problems and get you on a regular maintenance plan to make sure that problems like this never happen again.
2. Change or clean your air filter
Changing your air filter keeps the air in your home safer and cleaner, but it also saves energy, improves cooling performance and lengthens the life of your HVAC system. Filters should be cleaned or replaced at least every three months (or more often, depending on your system requirements). High-quality HEPA filters will yield the best results.
3. Keep A/C unit clear of weeds, vines and other debris
These materials can clog the unit and cause efficiency problems. This is a maintenance job you can do yourself in between professional routine maintenance for your HVAC system. It’s important every year to get a complete tune-up and clean out any dirt or grime that may be slowing things down.
4. Keep all vents clear and unblocked
Blocked vents will increase the pressure on your air conditioner and prevent the house from cooling consistently or evenly, so make sure vents aren’t blocked by furniture and remove any dust or debris that might be clogging them up.
