How often should I have my heat pump serviced?

You should have your heat pump serviced at least once a year. If you use your heat pump for heating and cooling, you should service it twice annually, in the fall and the spring.

What is the life span of a heat pump?

The average life span of a heat pump is 10-15 years. Because heat pumps run year-round to heat and cool your home, they don’t always last as long as a typical heating or cooling system. However, you can extend the life span by ensuring that your unit is routinely maintained by an HVAC professional.

Is Your AC Making Strange Noises? Here’s What They Mean

In Southern Indiana, where summer days often hit the low 90s and humidity levels remain high, your air conditioner faces a tremendous challenge. Your AC works overtime, sometimes resulting in unexpected sounds such as air conditioner knocking, air conditioner clicking, or even air conditioner banging. Whether you reside in the historic neighborhoods of Downtown Evansville or near local landmarks such as Angel Mounds, these strange AC noises are not just nuisances, they can be warnings of deeper issues. As Southern Indiana’s leading HVAC experts, Reliable Comfort is here to help you decipher what they mean for your system and provide you with the professional guidance you need.

What Are Normal AC Sounds?

Typically, your air conditioner has a characteristic soundscape. Occasionally, light sounds are common and generally nothing to worry about.

Steady hum: A low, continuous drone from the compressor and fan as they function.
Soft clicking: Intermittent, delicate clicks during startup or shutdown are a routine part of the system’s operation.
Gentle whirring: A subdued, rhythmic whir as air moves through ducts, keeping your home cool on sultry evenings.
Mild rattling: Sporadic, faint rattling sounds from the motor or moving parts, usually imperceptible but audible if you’re listening closely.

Why You Shouldn’t Ignore These AC Noises

Ignoring unusual sounds from your air conditioning unit can lead to more significant and costly issues down the line. Each abnormal noise provides clues that something in your system may be amiss. When your AC is making noise beyond its normal operation, it’s not just background sound. It could signal internal malfunctions that require immediate attention to avoid further damage.

Knocking Sounds

An air conditioner knocking sound can be particularly concerning. This noise often indicates that components within the system are loose or misaligned. The constant expansion and contraction of metal parts under high humidity and searing temperatures might cause these erratic impacts. If you hear knocking sounds, it’s wise to have a professional inspect your unit immediately to prevent potential long-term damage.

Loud Banging or Popping

If you detect an air conditioner banging noise or popping sound, this could be a sign of severe mechanical issues, such as internal component failures or compressor problems. These loud, abrupt noises are not typical and may hint at complications like disrupted circuitry or failing mounts. It’s important to act promptly and enlist the help of HVAC professionals to avert a complete system breakdown.

Hissing Sounds

Hissing noises coming from your unit should not be ignored. A pronounced hissing sound might indicate the presence of a refrigerant leak or issues with insulation. Given that your system operates in an environment with relentless heat and humidity, even a minor refrigerant drop can cascade into efficiency problems. Immediate assessment by a trusted technician is recommended to safely manage and repair the leak.

Grinding Sounds

When you hear grinding sounds, it’s a red flag that mechanical components might be worn or damaged. This auditory cue suggests that the motor or fan blades could be nearing failure. Left unattended, these grinding noises can culminate in more serious issues that may compromise the overall stability of your air conditioner, leaving you vulnerable during the hottest days.

Squealing

Squealing is yet another alarming sound, often caused by a slipping belt or an overburdened motor. This high-pitched noise is a warning that some parts of your system are under duress. Addressing such squealing promptly helps prevent further wear and tear, ensuring your cooling system continues to serve you reliably.
