24SevenHVAC: What are mini-split system noises that must be addressed immediately?

Mini-split system noises that must not be ignored

Mini-split systems have always been ideal for a single space or multiple rooms such as garages, porches, or sunrooms, split systems. An effective way to manage temperatures inside a given area, mini-splits are commonly used in multifamily housing or as retrofit add-ons to houses with "non-ducted" heating systems. However, when mini-splits begin producing certain noises, the owners must take professional help to investigate and resolve the issue at the earliest. 24SevenHVAC, an HVAC system installation in New York, discusses the noises that must be addressed immediately to avoid severe damage.

Rattling/Crackling Noise

These usually metallic sounds indicate a loose component that is rattling against the body of the mini-split. A mini-split, made of two or more units, may have a loose bolt or a damaged fan or motor that needs immediate attention.

Buzzing/Humming

A buzzing sound is typical in HVACs. It may be caused by an electrical issue with the outdoor unit compressor overworked or handling more amps than usual. Electrical problems can be correctly diagnosed by an HVAC professional. Moreover, the unavoidable and natural sound of the condensate pump can be reduced by using insulating foam or a good curtain.

Hissing/High-Pitched Whistling

A hissing noise from the indoor unit is a red flag. Cooling equipment usually causes these sounds due to a refrigerant leak, which can irreparably harm the compressor if left unaddressed. A complete unit would need to be replaced in case of such damage. The refrigerant leak may result from a loose or cracked valve or cracked coils. However, in case of cracks in the ring, both the waves and the refrigerant will need to be replaced. This will be more time-consuming than when there was just a refrigerant leak.

Popping/Clicking sound

This noise may be caused by the plastic housing expanding or contracting while the system is on. Additionally, the unit may form ice when the cooling has been set at a shallow temperature. When the system defrosts to get rid of the ice, the popping sound of the ice cracking and falling can be heard. This is not uncommon, but if this occurs too frequently, there may be an underlying issue that needs to be addressed by a certified HVAC expert.

The importance of HVAC maintenance

It is essential to control the damage by calling an expert when faced with an HVAC issue. However, the best policy is always to call a professional HVAC expert like 24SevenHVAC to conduct regular inspections at least twice a year to prevent damage from occurring in the first place. Here’s how regular maintenance helps:

Decreases the frequency of damages and repairs.
Reduces monthly energy costs.
Increases the lifespan of the unit.
Enhances indoor air quality.
Saves time and money.
