When Should I Replace My AC?
For some situations, replacing only one part of your central air conditioning unit can cause a mismatch with the rest of the system, leading to a system malfunction. Keep reading to learn the difference between replacing just your evaporator coil, and replacing your whole HVAC unit.
Replacing Your Evaporator Coil
The evaporator coil in your heating and cooling system is responsible for removing the humidity and heat out of your home. As the heat in your home passes through the coils, the refrigerant absorbs the moisture and heat from the air, as cool air moves in.
If your evaporator coil needs to be replaced, this is typically due to erosion. As your HVAC unit is used, the refrigerant passing through your coils can wear it down over time, causing damage. Furthermore, as the coils weaken, your unit becomes at risk for having a refrigerant leak.
Should I Replace My AC?
Though it may seem cost-effective to simply remove your coil and replace it, this could potentially damage your system. Your air conditioner has two coils — the evaporating coil and the condensing coil. If only one is replaced, your unit may not be able to run efficiently.
You should replace your HVAC unit if:
- It is over 10 years old.
- You experience constant system breakdowns.
- Your home is not cooling down when the unit is on.
- The condenser or evaporator coils needed for your HVAC are obsolete and cannot be replaced.
