When it comes to your air conditioner, some basic maintenance is always easy to complete for anyone without knowledge and experience. However, if your unit is not performing as it should and you have executed a simple troubleshoot procedure but the issue persists, you may have to contact an HVAC professional. When your A/C unit chooses to give out during the extremely unbearable summer, immediate resolution is necessary. Although many air conditioning issues can easily be handled by homeowners, more serious problems require the help of a professional.
However, before contacting a professional, make sure to inspect your property thoroughly. You may want to make sure no other cause besides a malfunctioning unit is the reason as to why your home is not cooling properly. In some instances, it may be a simple escape of the much needed cool air through a faulty window that may need replacement. If that is the case, contacting an A/C technician may not do any good, instead you will have to contact a glass company near you to get the issue resolved. Nevertheless, if after completing the thorough inspection you determine it must be the hvac unit causing the problem, than make sure of the following possibilities.
Condenser is malfunctioning
If the condenser is giving you problems, the first step you should take is to make sure the unit is connected to an electrical outlet and have the power checked. If the power seems to be working just fine, switch it off and check for tripped circuit breakers or blown fuses. If so, reset or replace them and turn the power back on to see it works.
If everything else is functioning properly, check the thermostat. An incorrect working thermostat could be the cause, set it down to 5 degrees below to see if the unit starts. Now, if the motor does not start than the issue is most likely a defective compressor which will need to be serviced by a professional.
A malfunctioning unit will never cool a property effectively. If this is the problem in your case, try what has already been recommended; lower the thermostat by 5 degrees and try running the unit once again. If the issue continues to occur, you might have an unclean evaporator. Cleaning it is required, do so very gently and allow it to function for a couple of hours. Consider the possibility of having to change the unit if the problem continues to occur, this may simply mean your unit is not big enough.
Do not ignore the fact that the extreme summer heat can also influence the effectiveness of your air conditioner. Having a low temperature inside your home may not be as easy when it is extremely hot outside. Make sure you consult with an expert before deciding to change your air conditioner, particularly when the temperature has been unbearably hot.
Running unit that does not cool
Starting by checking the thermostat is not a bad when the unit runs but does not cool. If that is not the issue
If your A/C is running but you don’t feel any cool air, you should still check the thermostat though it’s probably not the problem. Next, take a look at the condenser. Is it dirty or blocked? If so, clean it and remove the blockage. The condenser can become blocked by tall weeds, grass or other airborne debris.
It could also be the result of a faulty compressor, or an inadequate amount of refrigerant in the system. Again, these are problems that a professional needs to address.
Unit shuts on and off repeatedly
This is another problem that can happen with a dirty or blocked condenser unit, as well as a dirty evaporator. Most of the time, giving the entire unit a good cleaning and removing any obstructions will eliminate the problem.
When to call a professional
Cleaning your air conditioner is something you can do on your own, provided you have a basic understanding of the parts of the unit. But any time you need to address the coolant, you need the help of a professional HVAC contractor. If you’ve already done some basic troubleshooting and the problem still exists, you need to call a HVAC contractor.
