Your Air Conditioner Won’t Turn On & Common AC Problems

You wake up in a fiery of sweat and you’re not sure why. Was it a bad dream? Are you getting sick? Or, maybe it’s because the summer heat has set in and your air conditioner won’t turn on during the hottest time of the year. Don’t worry. Don’t panic. Every now and then, issues do arise, and the problem may be a simple one. With the weather as hot as it gets in the Temecula/Murrieta Valley Area, repairs are critical, so you’ll need to be ready for those issues. To help you prepare, here are a couple air conditioning problems you might face this summer.

Air Conditioner Will Not Come On

Sometimes, an air conditioning unit won’t come on, but the fan in the furnace seems to be working just fine. There are several reasons it may not be turning on. Check your thermostat, the simplest reason your air conditioner isn’t turning on could be that the thermostat needs new batteries. Most people don’t think about the batteries placed behind the plastic cover of the HVAC thermostat.

Also, did you make sure the thermostat set to below the current room temperature? If not, set your thermostat at a cooler temperature.

If that does not work, check the electrical panel. Just like when you have lights that will not turn on, the air conditioner’s fuse could be blown or the breaker could be switched off. If it is a blown fuse you’ll have to replace it. However, if the problem is simply a tripped breaker, all you need to do is turn it off and back on again. If you flip the breaker and it trips again, call a professional air conditioning technician to diagnose and repair the problem.

The Air Is Warm

An HVAC system should create cool air when it’s warm outside, so if your thermostat is set to cool your home, why are you getting hot air?

It may be that your system is working but something is preventing it from outputting the air temperature you want. There are several possible causes for this issue, but there is one that is easiest for you to check, the filter. Locate your air conditioning filter which helps remove dust, pollen, smoke, and other particles from the air before it enters your unit or your home. A dirty filter causes the airflow to slow or completely halt across the cooling coils. Without a filter, the internal parts of your unit can become very dirty decreasing the efficiency and causing expensive parts to fail. Simply by changing a filter regularly can save you hundreds in electric bills as well as avoiding costly repairs.

If the supply vents inside your home are blowing warm air, the air conditioning unit may be low on refrigerant. Without enough refrigerant, your AC cannot cool your home properly leaving you sweating and uncomfortable. The refrigerant liquid is what absorbs the heat in the air, consequently cooling the airflow into your home. The refrigerant may become low due to the age of the unit or a leak.

Ice build up on the evaporator coil is a sure reason your air conditioning unit is low on refrigerant. An air conditioning unit will not operate properly and will lose its ability to cool if the evaporator coil becomes blocked with frost or ice. The build up of this will cause the airflow in your air conditioner to not cool your home. If ice buildup continues to occur even after you turn off the cooling system and then back on, it is time to bring in an AC technician. An air conditioning technician will determine how to get your unit up and running and cool for the summer.

Don’t Get Stuck in the Heat!

You don’t want to be stuck in the heat of the summer with a malfunctioning HVAC unit. As soon as you notice you have a problem with your air conditioning unit, you should call a professional technician who will look at and make repairs that are necessary. Replacing smaller parts as needed, will prevent you from having to replace and install a new HVAC system prematurely.
