York At a Glance
York is one of the longest-running HVAC companies around, and they’ve been designing and manufacturing air conditioners and other heating and cooling systems in North America since 1874. Their line of cooling systems includes high-efficiency and economy models, but no matter what type of York air conditioner you have, it’s important to maintain it properly to get the most years from it.
That maintenance includes things like changing the filter, understanding error codes, and recognizing problems that require professional repairs. Today we’ll talk about all these things so you can keep your York air conditioner in tip-top shape.
How to Replace Your York Air Filter
Air conditioner air filters are an important part of the system because they ensure the best indoor air quality for your home. When filters get dirty, they don’t eliminate dust and allergens as effectively, the unit won’t work as efficiently, you’ll spend more on cooling costs, and you could end up needing repairs that might not otherwise be required.
Changing the filter is simple and straightforward, and these steps will walk you through the process:
- Shut off power to the unit to minimize dust and prevent shocks
- Find the filter either in the air return duct or on the interior unit
- Remove the grille from the air return, or remove the access panel from the unit
- Slide out the old filter
- Clean the old filter or replace it with a new one, using the directional arrows for guidance*
- Replace the grille or access panel
- Restore power to the unit
*To clean an air conditioner filter, wash it with soap and water, then rinse it clean. Allow the filter to dry in a cool dark place before putting it back in.

Common Air Conditioner Problems and Troubleshooting
Remember to turn your A/C completely off before opening it up to look around or attempt any fix.
Why is the unit leaking?
Air conditioners have drain lines that can become clogged with dirt, dust, and other contaminants. When this happens, the drain pan will fill up, causing water to drip from the unit and potentially causing more damage.
Why is the temperature fluctuating?
Temperature fluctuations are often the result of refrigerant leaks. When the refrigerant is low, the unit will have trouble creating enough cold air, and might even blow hot air instead.
Why isn’t the compressor working?
Compressors can break or stop working for many reasons, like a defective contactor or capacitor, loose connections, low voltage, or even seizing due to low refrigerant levels.
Why isn’t the unit running?
Lack of power is one of the most straightforward explanations, and it could be that a fuse blew, the circuit breaker tripped, or there’s a power outage. Beyond that, it could also be faulty wiring, problems with the communication system, high-pressure problems, or even something as easy as a bad thermostat setting.
Why isn’t the unit cooling my house effectively?
If your air conditioner seems to be working properly but still isn’t cooling your home the way you’d like, it could be because the thermostat setting is wrong or because the unit isn’t large enough for your home. Other potential causes include a dirty filter that’s reducing airflow, incorrect refrigerant levels, and moisture in the system.
Why does my house smell bad when the unit runs?
Do you smell last night’s dinner or other bad odours every time your air conditioner turns on? If so, then you likely have to clean or replace the air filter to eliminate the problem.
York Air Conditioner Error Codes
York air conditioners are equipped with a display panel that will tell you if the unit is functioning normally or if there’s a problem. To do this, York uses E and F error codes on the indoor unit and LED flash codes on the outdoor unit. When you know these codes, you can troubleshoot problems or call a technician for repairs before the issue gets worse. Here’s a list of common codes and what they mean:
| York Error Code | What this means |

| Error Codes E1, E2, F21, F7, F6, and F25, or 10, 11, 12, and 13 flashes | Sensor failure |
