Air conditioners have become an integral part of residential living. Air conditioners, or air cons as they are sometimes called, provide comfort and relief from scorching temperatures. Despite this, you should remember that even the most reliable AC systems may encounter issues over time.

In this article, we will discuss some common problems homeowners face with their AC units and explore practical solutions to these problems. So, read on to learn the common issues with residential air conditioners, how to fix them and why consulting with HVAC professionals for any AC issues is essential.

Common Air Conditioner Problems

Residential air conditioners are a welcome respite from the oppressive heat for homeowners. However, when these appliances come up with issues, it is easy to get frustrated. Getting acquainted with these issues can be pretty helpful in understanding how to handle them when they eventually arise.

Inadequate cooling

You may experience inadequate cooling with your air conditioning system, which can happen for several reasons.

Insufficient refrigerant levels

Low refrigerant levels can hamper the cooling efficiency of your air conditioner. You will do well to check regularly and replenish refrigerant levels to ensure optimal performance.

Dirty or blocked air filters

Where the filters become clogged, there would be restricted airflow, reducing the cooling capacity of your air con. Make it a habit to clean or replace air filters regularly.

Issues with thermostat settings

Incorrect thermostat settings can typically lead to inadequate cooling. Check to ensure that thermostat settings are calibrated to match your comfort preferences.

Uneven cooling

It is possible to observe that some parts of your home get cooled when the air conditioning system is working, while others don't seem to be cooled fast enough. This is one of the common air conditioner problems you may have to address. Should you be faced with this situation, the following are the likely reasons and the steps you need to take to address it.

Poor insulation

Uneven cooling can occur as a result of inadequate insulation. Enhance insulation in your home to create a balanced and comfortable environment.

Blocked or closed vents

Ensure that vents are unobstructed and open to allow even cool air distribution throughout your living spaces.

Malfunctioning ductwork

With leaky or damaged ducts, there can be inconsistent cooling. Regularly inspect and repair ductwork to maintain an efficient split system.

Strange noises

Part of what makes a good air conditioning system is when there is quietness along with coolness. The occurrence of strange noises can be an indication of some issues to attend to immediately.

Rattling or banging sounds

If there are loose components, they often cause rattling noises. Periodically, find time to tighten these components to eliminate disturbing sounds.

Hissing or whistling noises

Hissing or whistling can be signs of issues with air escaping. Take care of these concerns promptly or consult a professional for a thorough inspection.

Grinding or squealing sounds

Get some lubricate to reduce the friction on moving parts and eliminate grinding or squealing sounds.

Water leaks

Some people have considered water leaks in their air conditioning systems normal. Such water leaks can be indications of serious issues that need urgent attention.

Clogged or disconnected drainage lines

Make sure that drainage lines are clear to prevent water accumulation. Unclog or reconnect the drainage lines promptly in case of a water leak.

Refrigerant leaks

Tackle refrigerant leaks immediately to prevent damage to your air conditioning system. Call for professional assistance when you experience refrigerant leak repairs.

Frozen evaporator coils

Frozen coils can lead to water leaks. Thaw the coils and identify the root cause, such as a dirty filter or low refrigerant.

Constant cycling

There may be constant cycling with your air conditioning system, which is most likely an internal problem.

Incorrect thermostat settings

Adjusting the thermostat settings to match your cooling needs can prevent your AC unit from cycling frequently.

Dirty or damaged condenser coils

Remove condenser coils and clean them regularly to maintain optimal efficiency and prevent constant cycling.

Overworking due to external factors

Identify and address external factors, such as excessive heat or obstructions, contributing to the overworking of your air conditioner.

How to Diagnose the Problems

Before troubleshooting effectively, you should understand the source of issues, as this is crucial. Following these steps can help you systematically diagnose problems with your air conditioning units:

  • Check the refrigerant levels
  • Inspect the air filters
  • Review the thermostat settings
  • Evaluate the insulation
  • Examine vents and ductwork
  • Listen for unusual noises
  • Inspect drainage lines
  • Check for refrigerant leaks
  • Thaw frozen coils
  • Check the thermostat settings
  • Clean condenser coils
  • Identify and address external factors

Try to carry out a regular maintenance schedule to prevent common issues. It is advisable to follow a comprehensive checklist to keep your air conditioning system in top condition.

DIY For Quick Resolutions

Check vents regularly for obstructions and ensure they are open for uniform air distribution.

Inspecting and repairing ductwork

Homeowners can do ductwork inspections. Seal any leaks and address damages promptly.

Strange noises

Tightening loose components

Get rid of rattling or banging sounds by tightening loose components using basic tools.

Lubricating moving parts

As the manufacturer recommends, you can reduce friction-induced noises by applying lubricant to moving parts.

Calling a professional for complex issues

While homeowners can address some noises, remember that it's crucial to consult a professional for complex issues to avoid further damage.

Water leaks

Clearing clogged drainage lines

You can unclog drainage lines using a mixture of vinegar and water or a pipe cleaner.

Sealing refrigerant leaks

When you experience refrigerant leaks, you should seek professional assistance for proper diagnosis and repairs.

Thawing frozen evaporator coils

Turn off the air conditioner so that frozen coils will thaw. Address the primary cause to prevent future occurrences.

Constant cycling

Adjusting thermostat settings

Avoid constant cycling by setting the thermostat to a comfortable but efficient temperature.

Cleaning condenser coils

The outdoor unit should always be kept clean by removing debris and cleaning condenser coils regularly.

Addressing external factors contributing to overworking

You can find and eliminate external factors that disturb the smooth running of the system, such as heat sources or obstructions. If not removed, they can contribute to the overworking of your ac unit.
