Having central air conditioning unit can be a life saver, especially when you are in the middle of a heat wave. Therefore, if you want to know when it is time to call in an HVAC technician for assistance, read more.

Not All Rooms Are Equally Cooling Off

One of the biggest benefits of having a central air conditioning unit is that all of the rooms in the house should be equally cooled off. When this is not happening, you will want to get in touch with an HVAC specialist. Most of the time, when one or more rooms are suddenly no longer getting as cool air as the rest, it has something to do with the duct work that runs behind the walls.

If there is a section that is starting to disconnect from another piece, it can cause a lot of the cool air to filter into the wall cavity instead of making it all of the way through to the vents in the rooms. An HVAC technician will send a micro camera through all of your duct work until all spots of weakness are located. This way, he or she will know exactly where the work needs done without having to rip all of the walls out.

The Air Conditioning Unit Is Louder Than Normal

A small amount of sound coming from a central air conditioning unit is to be expected. This is generally described as a low humming sound by people who have their own units. You might hear the occasional light clicking sound as the unit turns on and off but that should be about it. Therefore, if you are noticing a lot of loud thumping or banging sounds, you will want to quickly schedule an appointment with a skilled HVAC technician. There could be an issue within the motor or internal fan. Either way, if the problem is not resolved quickly, you could find yourself without any cool air for your home.

It Constantly Runs No Matter What

You do not want to have a central air conditioning unit that runs non-stop. If it does, then there is a good chance that you are going to wear out the internal parts of the unit before they would normally expire. Also, you risk ending up with an incredibly large electric bill. Therefore, if you suddenly notice that the central air conditioning unit seems to run more than it should, you will want to call in a technician for assistance.

It does not matter if the problem is big or small, you always want to make sure that you are hiring the best HVAC technician in your local area.
