Air conditioners are a wonderful comfort during hot summers, but strange noises coming from your unit can be a cause for concern. Our St. Paul air conditioner repair team knows that air conditioners can make a lot of weird noises, and for the most part the majority of them are easy (and safe) to ignore.
The first step is identifying the type of noise. Here are some common ones:
- Buzzing: A persistent buzzing sound could indicate several issues. It might be a loose electrical component, a malfunctioning fan motor, or even a frozen evaporator coil.
- Screeching: A high-pitched screech typically points to a failing fan motor, either in the outdoor condenser unit or the indoor blower fan.
- Banging: A banging noise usually suggests loose parts within the unit, which can be caused by wear and tear.
- Gurgling: Gurgling sounds might indicate a clogged condensate drain line.
There is one noise that you should absolutely pay attention to, though, because it’s more likely than not a warning sign that something is about to go seriously wrong with your unit. That noise is a prolonged hissing sound.
What Does It Mean When Your AC Is Hissing?
If your AC is making a hissing noise it could mean that there is likely gas leaking from a hose or pipe or an issue with the compressor. While leaks are usually relatively easy to repair, compressors can be expensive. You may be better off getting a new air conditioning unit, but your Hoffman technician can give you their advice on whether to repair or replace it.
The ultimate decision is always left up to you, but if you do decide to replace your system we have a great selection of Lennox systems to choose from and you can save $1,700 when you buy from us.
