If your Lennox air conditioner isn’t functioning normally, the fault is likely to fall onto the fuse, circuit breaker, coils, or air filters. Beyond these parts being the cause of your A/C problems, your issues may also arise from the heart of the air conditioning unit: the thermostat. Each and every one of these parts are complex, can be difficult to understand, and are unsafe to handle without proper training. You should not try and repair any of these parts yourself. Here is how to safely assess the condition of your Lennox A/C in Vaughan!
Lennox A/C Won’t Turn On
The likely culprits for a Lennox air conditioner that will not power on are the fuse, circuit breaker, or a faulty thermostat. First, check the 240 volt and 120 volt circuit breaker that controls the blower. If they are in the “On” position and still not functioning, then the breaker is likely not the issue. Find the thermostat and make sure it is set to “cool” and not “off” or “heat”. Check your fuse box to see if one has blown. If none of these are applicable to you, you will need to contact a repair professional for a diagnosis and repair.
Poor Air Flow Production
If you find that your air conditioner is producing cold air, but not enough airflow to sufficiently cool down a room or the entire house, then your air filter or ductwork may be the cause. Check the air filter to see if it is dirty; if it is, try to clean it off as well as you can. If the filter is particularly dirty, it will be easier to just replace it. If this does not fix your problem, then peek around your ductwork. If you notice any disconnections, call a repair technician right away.
Not Humidifying Enough
If your Lennox A/C is insufficiently dehumidifying your home, it’s time to check the condensing unit and coils. It is very likely that these two are too large for your household. If this is the case, you will need to replace them. However, this is an expensive replacement, so we recommend confirming that this is the issue with a skilled repair technician before moving forward.
