Things To Consider: When To Fix Or Replace An Air Conditioner
When considering whether to repair or replace your air conditioner, start with figuring out how old is. Check the rating plate on the unit outside for a date. Typically an air conditioner will last about 10 years before they can start to have issues.
TIP: Take the age of the AC x the cost of the repair and if it is = to 50% or more of a new air conditioner, we would strongly suggest investing in a new one. Call us today.

Things you can Check before booking an AC Repair
Here are some things you can try to troubleshoot your air conditioner. Watch out for these signs to help reduce further damage to your air conditioning unit. If you catch the problem and repair it early, it may save the unit from having to be replaced.
Things you can try:
· Reset the breaker – sometimes the air conditioner breaker trips during the Winter and it needs to be reset. Check the breaker or check for a blown fuse on your electrical panel.
· Change your furnace filter – your furnace and air conditioner work together so it’s important to continue changing your filter through the Summer. A dirty filter acts like a BLOCKED filter so air can’t get through causing your system to work harder than it has to. If there is condensation or freezing on or around your furnace, check your filter, shut your air conditioner off for a few hours and try again.
· Remove your AC cover – before running your air conditioner, make sure you remove the cover to prevent freezing & possibly ruining the compressor. Your air conditioner needs proper airflow to work.
· Check the thermostat – make sure the thermostat is set to COOL and not set to fan. We suggest adjusting the thermostat to a temperature based on your comfort level, not necessarily just what temp the thermostat says. We do not recommend cranking the AC as this may put stress on the system which can result in needing a repair and higher energy bills… TIP: Think of it like a car. Typically, better fuel economy is achieved with consistent highway driving, not stop and go.
· Keep vents clear – moving things like furniture away from the vents will promote easier air circulation so your furnace and air conditioner can work with ease. This can result in better comfort & energy savings. Check that your vents are open, free and clear.
· Water dripping from the inside portion of the AC unit – it could be one of two problems: 1) a plugged condensate drain (typically an inexpensive repair) or 2) the indoor evaporator coil is freezing up. This could be due to either an airflow issue or possible refrigerant charge issue. Change your filter, turn off the system and call us for help 519-439-4328.
*Please remember to ensure all of your ductwork vents are open, free & clear and that your air filter is clean. If this all checks out and you are still having issues, please call Donaldson for professional help with your air conditioner.*
