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.

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:

1. Shut off power to the unit to minimize dust and prevent shocks
2. Find the filter either in the air return duct or on the interior unit
3. Remove the grille from the air return, or remove the access panel from the unit
4. Slide out the old filter
5. Clean the old filter or replace it with a new one, using the directional arrows for guidance*
6. Replace the grille or access panel
7. 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.

Remember to turn your A/C completely off before opening it up to look around or attempt any fix.

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:

You’ve learned about the common problems people encounter with their air conditioners and the different error codes you might see displayed on your unit, so now we’ll talk about which of these issues requires a trained and certified technician to fix. If you experience any of the following, turn your air conditioner off and call an HVAC technician for a repair:

• Refrigerant Leaks
• Water Leaks
• Strange or loud sounds
• Compressor failure
• Fan stops running
• Unpredictable operation
• Burning smells
• Worn or damaged power cord
• Lack of cooling power or no cooling
• Wiring, voltage, and electrical problems
• Fuses that blow frequently or a circuit breaker that keeps tripping

Finding a good HVAC technician is like finding a good mechanic, and some of the most important qualities to look for include trustworthiness and reliability. But there are also other characteristics that are important in a good HVAC technician, and they include having the right training, licenses, insurance, and experience.
