Pilot Or Ignition HVAC Problems

Ignition problems can result from a number of causes. A dirty pilot, flame sensor, or burners can cause a pilot outage, short cycling, furnace lockout, or delayed ignition of the burners. It could also be a result of a gas supply problem or just wear and tear of an ignition component that needs replaced like the hot surface ignitor or thermocouple. Either way, it is best to contain these problems handled by a trained service technician since this deals with dangerous elements like natural gas and high voltage.

A Problem with the Refrigerant

Refrigerant is delivered to the evaporator coils in your unit so that those coils can remove heat and humidity from your home. If there is a leak somewhere in that pipeline, the evaporator coils aren’t getting the proper refrigerant flow they need to expel the hot air and humidity from your home. The most obvious sign of a refrigerant leak is the noticeable loss of cooling and possibly the presence of ice on the evaporator coils and refrigerant tubing; as a result. That leak could also mean that you don’t have enough refrigerant to cool properly.
