Signs That it is Time to Repair or Replace an Air Conditioning Unit

An efficiently working air conditioning unit is vital to a household's health and comfort during the hot summers. Regular air conditioner maintenance by an HVAC professional ensures that it does not break down when it is needed the most. 

An air conditioner system is complex, with several components which may break down and require repair or replacement at some point. It is essential to pay attention to the function of older AC units as the cost to operate an inefficient unit is considerably high. No air conditioning unit fails suddenly; there are some common warning signs it will give before going kaput.

Here are a few telltale signs to look for indicating that there is a need to repair or replace the air conditioning unit:

Warm air

The primary job of an air conditioner is to blow cold air to keep the home comfortable on hot days. If the unit is blowing warm air from the vents even when the thermostat is on cooling mode, it is a sign that the AC needs repair. Low refrigerant, duct issues, or compressor problems may prevent the unit from blowing refreshing cold air. 

Poor airflow

No or weak airflow from the vents is a common sign that an air conditioning unit needs repair. It makes it impossible for the AC to provide proper cooling and keep the indoors comfortable. Call a pro to evaluate whether the poor airflow is due to a failing compressor, clogged air filter, broken motor, blocked ducts, or any other issue. 

Unusual sounds

Sudden loud and strange clicking, grinding, squealing, screeching, or banging noises from the cooling unit are unusual and may indicate a grave problem. While the cause of some noises is easier to fix, others may mean that it is time to upgrade the unit.

Foul odor

Unpleasant burning, smokey, or musty smells indicate that the unit needs attention. Mold, mildew, or issues with the electrical wiring and insulation are the possible culprits. A professional can clean the air ducts and check the wiring to fix the problem.

Higher energy bills

An inefficiently operating air conditioner can cause an inexplicable rise in energy bills without any increase in usage. Leaks in the ductwork, a broken or damaged thermostat, and a unit nearing the end of its lifespan can decrease the AC efficiency. 

Leaks around the unit

Excessive moisture build-up or water puddles around the AC indicate that it is not performing correctly and needs repair. A blocked or broken drain line can cause a condensate leak. If ignored, it leads to water damage and reduced system efficiency. Call a professional immediately if the AC unit is leaking refrigerant, an odorless, poisonous gas that poses a severe health threat to the family. 

Old and aging unit

Consider upgrading the existing AC unit if it is more than ten years old or requires frequent, costly repairs. A new high-efficiency air conditioner significantly reduces the cooling costs, requires fewer repairs, and provides greater comfort.

Call an HVAC company if you notice any of the signs outlined above. A technician can inspect and perform the required repairs or recommend upgrading to a new and more efficient unit.
