Luxaire At a Glance
Luxaire began in 1939 with coal and gas furnaces and eventually branched out into various home comfort solutions. Their focus is on quality units that set the standards for performance and efficiency. You can be confident in purchasing a Luxaire air conditioner that will last you a long time and provide with you reliable cooling for your home.
Luxaire works toward creating commercial and residential heating and cooling units that are energy-efficient, to save money and be environmentally friendly while still providing exceptional service. Like all air conditioners, Luxaire units require some basic maintenance to keep serving you well for years after your initial purchase.
There are a few steps you can take to ensure that your air conditioner remains in good condition to avoid costly repairs or replacement. Keeping an eye on your unit can help you catch minor problems before they get out of control. Our guide below goes through tasks that you can do as a homeowner to take care of your air conditioning unit.
How to Replace Your Luxaire Air Filter
Replacing the filter is a relatively easy task that is important to do to ensure that your air conditioner is at peak performance and not being hindered by dust and debris. It’s good practice to change the filter every few months, or more often if you have a pet.
- Locate your air filter. It may be in the return duct, furnace or air conditioner.
- Turn off power to the furnace or A/C before you begin to work.
- If the filter can be reused, clean it following the instructions in your owner’s manual. If not, make sure to purchase a filter that is compatible with your unit.
- Replace the filter the same way that you found it, taking care to ensure that the airflow direction is correct.
- Close the unit once you’re finished working and turn the power back on.
Other General A/C Maintenance Tips
Keeping your air conditioning unit at performing at its best is not a difficult task. By making the tasks below as part of your household care routine, you can avoid costly repairs. Be sure to shut off power to your unit before you open or clean it.
1. Clean around your unit
Keep the area clear by sweeping away leaves and other debris that may be around your outdoor unit. Ensure that no plants or overgrowth around your air conditioner can potentially block the airflow from your air conditioner.
2. Clean and straighten the fins
You can remove the outer cover and vacuum it, then use a gentle spray from the inside to wash away dust and dirt from the fins. You don’t want to use harder pressure in case you damage the delicate fins. You can straighten the fins out by using a butter knife or a fin-straightening tool from a home hardware store.
3. Ensure the unit is level
Measure with a leveller to check that the pad that your unit rests on hasn’t tipped. This will stop your compressor from tilting and reducing its working lifespan.
What’s Wrong With Your Luxaire Air Conditioner?
Remember to turn your a/c completely off before opening it up to look around or attempt any fix.
| Is your air conditioner... | The problem might be your... | What's wrong? | How you can fix it |
|---|---|---|---|
| Thermostat | Batteries may be dead, or the thermostat may be switched off. | Change the batteries and check that the thermostat is set to cool. | |
| Circuit breaker | The breaker may have been switched off. | Turn the switch to the “on” position. | |
| Not blowing cold air? | Air filter | The filter may be clogged or full of debris. | If you haven’t changed your air filter in a while or you’ve been running your A/C more than normal, it’s probably due for a change. |
| Outside unit | The air conditioning unit outside your home may not be able to vent the hot air from your home properly. | Check to make sure your unit has at least 2 feet of clear space. Remove vegetation and leaves from in, on and around your unit. | |
| Refrigerant | If the refrigerant is leaking, you won’t be getting cool air. | Call an HVAC expert to fix the issue, since it requires trained expertise. | |
| Insulation | Old homes may have insulation gaps that let the cool air leak out. | Windows are common culprits, consider replacing or using blackout curtains. | |
| Dripping water? | Condensate line | The PVC pipe that leaves the A/C unit may be clogged. | Use compressed air to clean it out and allow normal function. |
| Making odd sounds? | Blower motor or belt | Squealing may indicate that there is an issue with the belt or blower motor. | Adding lubricant to the oil port can help the parts run smoothly. |
| Fan blades | If the sound is more like a slapping noise, the problem may be with the blades of the fan. | Something may be stuck in the blades. Turn off power to the unit to check if this is the cause and remove it. |
Luxaire Air Conditioner Error Codes
