Top Signs Your AC Needs Repair Before the Hot Indianapolis Summer
With Indianapolis summer temperatures frequently reaching the 90s, your AC system is your first line of defense against the sweltering sun. To stay cool and comfortable all season, you need to keep your AC well-maintained so it doesn’t break down when you need it.
Here, the HVAC experts from Northern Comfort Systems will discuss some common signs that you need AC repairs and how to prevent future AC issues.
Signs You Need Prompt AC Repair
Weak Airflow
A decrease in airflow indicates an underlying air conditioner problem. Poor airflow can mean your air filter is dirty or clogged from dust and other debris, restricting cool air from passing through. Weak airflow can also signal an issue with your system’s blower fan or ductwork system.
Warm Air
If your unit produces warm air when set to a cool temperature, you may have a refrigerant leak. Air conditioners with low refrigerant levels can’t properly cool the warm air passing over the unit’s evaporator coils, so a professional must recharge the refrigerant and seal leaks.
Unusual Noises
Loud, unusual sounds often mean an internal component is loose or damaged. This problem can be caused by a malfunctioning compressor, unbalanced fan blades, a loose or worn belt, frozen evaporator coils, and more.
Signs to watch out for include:
- Banging or rattling: These noises are common when components become loose or worn.
- Hissing: This often indicates a refrigerant leak.
- Buzzing: This is often caused by electrical issues that require immediate attention.
- Grinding: This can suggest a worn-out motor or mechanical issue.
Unusual Odors
Abnormal or foul odors often signal an underlying issue with your unit that requires professional repair. Some of these include:
- Musty odors: Mold or mildew in your unit or ducts can produce musty odors.
- Burning odors: Burning smells often mean parts within your system are overheating.
- Chemical odors: Refrigerant leaks can smell sweet or chemical-like and be dangerous if left unaddressed.
Frequent Short-Cycling
If your AC constantly turns on and off, it could be a sign of a bigger issue. Frequent short-cycling strains your system and leads to inefficient cooling and higher energy bills. Frequent short-cycling is often caused by:
- Dirty air filters
- Dirty or frozen coils
- An oversized unit
- Thermostat issues
- Low refrigerant levels
Rising Energy Bills
If your monthly energy costs are higher than usual, your unit is likely operating inefficiently. Rising energy bills can be caused by a range of problems that require professional diagnosis and repair.
Protect Your AC With Preventative Maintenance
Preventative AC maintenance is key to extending your unit’s lifespan and avoiding costly repairs. It’s recommended to schedule expert AC maintenance in the spring, ensuring your unit is ready to meet your cooling needs when summer sets in.
You can also take these steps for DIY air conditioner upkeep:
- Clean off or change your air filter every one to three months
- Clean dirt and debris off the coils
- Remove obstructions from the outdoor condenser
- Keep an eye on your home’s ductwork
- Inspect and recalibrate your thermostat as needed
