HVAC maintenance can sometimes be difficult, especially if you don’t have a lot of experience with them. There are many possible causes for HVAC problems, some of which can be more severe than others. While ice forming on your air conditioner is a common problem, many homeowners don’t know how to fix it. There are many resources online and offline that will help you understand your HVAC system and how it should be maintained. Continue reading to learn why your air conditioner could have ice and what you can do to fix it.


It can be difficult to find the problem with your AC, especially if it is your first time. You are not the only one asking ” Why is my AC iced up?” Ice on your air conditioner could be caused by many things. The most common reason is refrigerant leaking. The condensation from the air that is not filtered through the coil of the evaporator will freeze and not drain into the pan as it should.

Bad wiring could also be the problem. Your AC could have a problem with its wiring if it turns on even though your home is at the desired temperature. This could be due to a problem with your thermostat or an electrical contact that has failed in your outdoor unit. Ice forms when the compressor continues to work after the fan stops. Your air conditioner can also be impacted by dirty filters or evaporator coils. This can sometimes be fixed with a filter change. However, if you notice ice formation you should contact a technician.

Regular maintenance is the best way to prevent HVAC problems or breakdowns. Your HVAC system should be inspected at least annually. The filter should also be changed every 90 days. However, many homeowners prefer to have their filters changed on a monthly basis in order to maintain peak performance.


A smart thermostat is the best investment you can make to increase the efficiency of your HVAC system. Smart thermostats can be connected to Wi-Fi and are compatible with other forms of home automation. Smart thermostats can also adapt to your schedule. This means your system will only consume the energy necessary to maintain your desired temperature at home. This could have the effect of significantly lowering energy costs.

Making small lifestyle changes can make all the difference when temperatures start to rise. Although it may seem counterintuitive to do so, you must close all windows. This will allow air to cool down and keep hot air out of your home. Fans can be used to circulate the air and switch off heat-emitting led lights. You might consider avoiding the oven, which can raise indoor temperatures.

While it can be difficult to keep your home cool and not increase your utility bills, there are some things you can do. Preventive maintenance is the best way to avoid breakdowns and keep your HVAC system running smoothly. You should contact a technician immediately if you notice ice in your AC that won’t go away when you change the filter. Smart thermostats and standing fans are also great options to beat the summer heat.
