HVAC systems make your home comfortable all year round, they heat during the cold winter months and cool during the summer. The summer can be very hot and sticky should your air conditioner break down. Repairing an air conditioning unit can be very expensive, even if the fault is something minor. It’s always sensible to give the AC unit a quick once over yourself to see if you can save yourself a bit of money. This guide will look at some very simple DIY AC Repair tips.
Tip 1 – Check the Settings
There’s nothing more frustrating than calling an air conditioning engineer out only to discover that you have the AC unit on the wrong settings. Almost all air conditioning units have a fan only and cooling mode. If the air conditioner isn’t cooling, first make sure that the AC unit is set to cool and not in fan or heat mode. Adjusting the temperature while in this mode will not change the temperature of the room.
Tip 2 – Checking Power to the Unit
If the AC unit won’t turn on at all then this could be something quite seriously wrong, but it could also be something very simple. First, rule out all the simple faults before calling out an AC technician to diagnose and fix the problem. An air conditioner should be on its own dedicated circuit, first, check the electrical panel to make sure nothing has tripped if it has then reset the breakers. Also, make sure that the main switch to the AC unit is turned on.
Tip 3 – Checking the Thermostat
Your AC unit is controlled by a thermostat, this regulates the temperature in your room. If the room gets too hot then it will turn on the AC to cool it down. A lot of thermostats are wireless and powered by batteries. If the batteries have run out then this will prevent the AC unit from powering up. Try turning off power to the air conditioner, replacing the batteries in the thermostat and turning it all back on. If this works then you have saved yourself a lot of money. If not, the thermostat may need replacing. This is something that’s quite easy to do, but you might want to call in a professional to help you.
Tip 4 – Frozen AC
If your AC drips water or the coils are frozen, then it could be caused by a blockage or dirt building up inside the unit. The ice buildup will prevent your AC from cooling properly. To melt the ice turn on the AC unit without cooling. Do this by either turning the AC unit on in fan only mode or raising the temperature of the thermostat very high so that it doesn’t cool.
Tip 5 – Checking Filters
Checking and cleaning the filters is another easy job you can do yourself without an expensive visit from an engineer. If you’re unsure how to remove the filters then read the manual that came with your AC unit, this can also normally be found online if you are struggling. With the filters removed, either clean or replace them. By cleaning or replacing filters you should improve the air flow through the air conditioner, which will allow it to work much more efficiently.
Hopefully, these tips have managed to help you fix your AC unit and save you some money at the same time. If it’s still not working then you might need to contact an AC repair engineer to get it back up and running.
