The filter is a part of the unit that is easy to change, but unless you maintain a schedule, then you probably won’t remember to change it on a regular basis. If the filter becomes too dirty, then it can prevent air from circulating through the system as it should. Debris can become lodged in the system, which can cause it to overheat or blow a fuse. Our HVAC repair company can come change the filter before the heat of summer arrives. There is sometimes a filter in the main unit that needs to be changed as well.
If you notice any kind of burning smell in the home when you turn the AC unit on, then it could be from faulty wiring. This is an emergency that needs to be addressed as soon as possible. Don’t turn on the unit until the wiring can be fixed or replaced. If there is only minimal damage to the wiring, then it can often be stripped, and new wiring can be installed in the area. However, if there is extensive damage along the wires, then you will likely need to get everything replaced before operating that unit. This is a common problem in older homes and in homes that have seen moisture damage.
Low Freon Level
When the Freon gets too low, it won’t allow the system to cool. Most units don’t see a drastic reduction in the levels of the chemical, but it’s normal to see some lower levels over time. If you notice a significant decrease, then it is probably from a leak or from the system itself. Our HVAC repair company can examine the unit to determine where the leak is and the amount of damage that has been done to the system.
There is a fan that removes the hot air from the home to the outside. If you notice that there is still hot air inside the home after the unit has been on, then it could mean the fan is not working. Damage from a storm could cause the fan to become broken. Sometimes, lightning can strike the AC unit. This is another type of emergency that you need to get fixed as it could start a fire if the unit is hit in the right place. The fan could stop working due to the age of the system. Regardless of why the fan doesn’t work, you need to get it fixed as the unit will keep running since the thermostat senses that the temperature in the home isn’t going down.
At times, there is a lack of power to the outside unit. This could be because it has become disconnected from the main power source, or it could mean something much more significant. If you suddenly have a loss of power without losing power in other areas of the home, contact an AC repair company to come examine the wiring and the fuses that operate the unit. Another common problem is when the coil becomes frozen. This means that there isn’t proper circulation through the unit. It could be something as simple as a filter that needs to be changed, or there could be debris stuck in the ducts inside the home.
