Signs Your Air Conditioner Needs Repairs

When your air conditioner acts differently, you’ll notice right away. Be aware if you notice any of the following issues with your air conditioner, you may need to call an experienced service technician for help.

No Cool Air Coming From Vents

You came home from work, expecting to find relief from the heat, and instead came home to a hot house. Your air conditioner isn’t working properly and no cool air is coming from the vents. This could be a power supply issue, an airflow problem, or a broken internal component. A good place to start is to double-check your thermostat to make sure you set it to “cool,” and make sure that the breaker the air conditioner is on hasn’t been tripped. If your air conditioner in St. Louis still isn’t working, please turn your system off and call Welsch for help.  

Loud Noises Coming From AC Unit

If you hear scraping, squealing, or grinding noises coming from the unit while it is running, call on an expert at Welsch right away. 

Strange Odors When the AC is Turned On

It’s not unusual to smell something different when you’ve turned on the air conditioner for the first time this summer, but that smell will dissipate fast. If you smell a strong odor, such as a burning or musty smell, those are issues that should be addressed as soon as possible.

Leaks Around The AC Unit

Air conditioners rely on freon and refrigerant to keep cool. These chemicals should be contained within your unit. So if you ever notice leaks, either moisture or chemical, call a professional service technician to investigate.

AC Unit is Over 12 Years Old

The lifespan of most air conditioners is 12-15 years. If you’re noticing issues with your air conditioning keeping up with demand, and it’s close to or over 12 years old, talk to one of our experienced technicians about whether repairs can be made or if it’s smarter to replace your unit.
