Your A/C is probably the most used system in your home, especially during those hot Florida days. It is important to maintain it and keep up with any issues that may arise.
Here are 5 ways you can repair common air conditioning system issues:
Is your air-conditioning system losing cooling power? There may be ways you can troubleshoot the issue yourself without having to hire a professional.
Here are the components of your system where problems may occur:
- Expansion valve
- Evaporator coil
And then there’s the hub of your heating and cooling system – the thermostat. If you can not find the root of the issue, this is a good place to start.
2. A/C will not turn on
The most common cause with your air conditioning not activating is usually due to a tripped circuit breaker, blown fuse, improperly set thermostat, or an internal switch being turned off.
Some solutions include, but are not limited to:
- Make sure the thermostat is in the COOL position and not on OFF or HEAT and set below the current room temperature.
- Check to see if your double-pole breaker is in the ON position, as well as all other switches.
- Look at your condensate overflow tray and get rid of excess water.
3. Poor airflow
This is typically an easy fix because poor airflow is usually a result of a dirty air filter or blocked ductwork. To solve this problem, replace your air filter and inspect all ductwork. It is also a good idea to make sure the register dampers are open on all vents in the house.
4. A/C is not dehumidifying
Usually this is a result from an air-conditioning system that is too large. Since a large system cools the air at such a quick rate, the thermostat will turn off before the humid air can make its way to the cooling coil to be dehumidified.
There is only one solution to this issue, and it is to replace your unit with a smaller one. You could extend the cooling load, but that would involve adding additional ductwork.
5. Compressor cycle is too short
This means that your compressor is turning off and on frequently. What usually is the cause of this problem is an obstructed thermostat, leaking refrigerant, iced coils, or an oversized cooling system. Here are some possible solutions:
- Check to make sure the thermostat is not being blocked.
- Repair any bent condenser fins with a fin comb.
- Replace the air filter.
- Check for refrigerant leaks.
- Replace your unit with one that is properly sized.
