After a while of usage, it is inevitable that your air conditioning unit is going to experience some form of fault, as its condition deteriorates due to general wear and tear. Unless your system undergoes regular AC maintenance, it is unlikely that these potential problems will be spotted until they actually start to cause a change in the output of the unit itself.

One such issue is when your unit starts to blow warm air, instead of the cool, crisp air you invested in. There could be several reasons as to why this is the case, with some being easier to spot than others, which will be highlighted in this blog post. So before fretting about why this problem could be occurring, be sure to check out for these potential issues…

A faulty compressor

This takes care of how the refrigerant (the substance that produces the required temperature) is circulated around the unit. If there is a problem with this then the whole system could be malfunctioning and nullify the effect that your AC unit is meant to have. If the refrigerant can’t get around the system effectively, then it will not be of the required temperature that you want (for convenience) or need to keep your room at a specific temperature for longer.

If you have had the unit for a long time without repair or an AC service, then your compressor could freeze up and stop the refrigerant from travelling around your unit as it should.

This issue is more common than you may think, and you might want an expert to check this out sooner rather than later. Here at Bluebird Refrigeration, we are able to use our expertise to quickly diagnose the problem and tell you if you need a replacement compressor or not.

Ventilation issues

A problem with the ventilation of the air conditioning unit could be another reason why it is blowing warm air. The vents of your unit could be blocked, forcing the cold air to only come out of a specific vent, rather than them all. This dramatically changes the temperature of your room when the AC unit is running, as it will often be a lot less cool than you asked for!

One consolation is that this issue is very easy to spot as if one side of your unit is blowing cold air and the other is not, then it will be a problem with the ventilation of the unit.

If this is the case, then you might want to acquire the help of an expert in order to get your AC unit back up and running in no time. The AC repair team at Bluebird Refrigeration have dealt with all kind of faults and problems up and down the country for a number of years, so are in the perfect position to be of assistance.

Is your thermostat set correctly?

Finally, it may be worth double-checking that your thermostat is set at the correct temperature before you ask for professional input. We’re sure that you would have done this already, but the reason that your AC unit is blowing hot air could be because the temperature is set to “heat” instead of “cool”.

We’ve seen it happen before when we have come to do our checks, so don’t think this is a silly precaution to take! The thermostat can sometimes easily be bumped by someone else in the building, so be sure to check this out as a potential reason as to why your unit is blowing hot air.
