Most Common Problems To Happen With Air Con
There are many problems that can arise with air conditioning and most will need a professional contractor to carry out a repair on them. Whether it’s a small problem or larger issue, not having it repaired could prevent you from using your air conditioning. Some of the most common problems that happen with air con include:
Dirty Filter
A clogged filter restricts air flow through the unit decreasing its efficiency and reducing the ability to cool the air. If you haven’t cleaned the filter in your rooms air conditioner recently, then it’s important that you or an engineer do it. Filters on AC units should be changed regularly especially when the air con is used a lot.
External Factors
AC units might suffer from problems due to external factors and conditions. It’s important to avoid placing lamps or tv sets near the thermostat that controls your unit or system. The thermostat will sense the heat from these appliances, which means your air conditioning will run for longer which could lead to problems developing, especially if the unit or system is used regularly.
The AC Cools Unevenly
Temperature fluctuations can be the result of leaks in ductwork, poor insulation, or blocked vents or registers. Ensure that the vents throughout your home are open, clean and unobstructed. You might find that rooms with south-facing windows feel hotter than other rooms. If this is the case, use blackout curtains over the windows during the warmest times of the day. Another solution is the professional installation of separate zoning systems in your home that allow you to control the temperature in specific areas.
Wrong Thermostat Setting
A common problem with air conditioning is that the thermostat setting is wrong. If you have a programmable thermostat, make sure you programme it so your home is at a comfortable temperature when you’re there and a bit higher when you’re not. It’s important to keep in mind that for every degree you raise the temperature, you could be saving around 3% on costs.
Low Refrigerant Levels
If your air conditioning system isn’t cooling as effectively as it used to, low refrigerant levels could be the culprit. Refrigerant is the substance that absorbs heat from inside your property and releases it outdoors. When levels are low, it’s often due to a leak somewhere in the system. Simply topping it up won’t solve the problem—an engineer needs to locate and repair the leak before recharging the system. Signs of low refrigerant include warm air from vents, frozen evaporator coils, or hissing noises near the unit. Ignoring the issue can lead to compressor damage, which is far more costly to fix. Regular servicing helps identify refrigerant issues early. If you’re in Basingstoke and notice your AC underperforming, call in a qualified engineer to check for leaks and get your system running efficiently again.
Lack of Routine Maintenance
One of the most common causes of air conditioning problems is simply neglect. Like any mechanical system, air conditioners require regular maintenance to stay in good working order. Over time, dust, debris, and grime build up inside your system—especially on filters, coils, and fans—which affects performance and increases wear on components. Without routine servicing, minor issues like dirty filters or loose electrical connections can evolve into more serious breakdowns. A poorly maintained system also works harder to deliver the same level of cooling, which means higher energy bills and a shorter lifespan for the unit. To avoid unnecessary repairs and keep your air con running efficiently, it’s advisable to schedule professional maintenance at least once a year. This is especially important in places like Basingstoke, where temperature swings between seasons can put extra strain on systems.
Plants
When a system is outdoors it’s important to keep the surrounding areas clear. To allow good airflow, plants should be kept two to three feet away from the system. In addition to keeping it away from general plants there should also be a clearance of 5 feet of height from the top of the unit to the nearest tree.
Strange Noises
When screeching or squealing sounds come from the blower motor this indicates a motor bearing problem or a faulty belt that’s at risk of breaking. Clanging, rattling, thumping or banging generally means there’s a problem with the motor or blower assembly. If you hear any of these noises, turn off the A/C and call for an air con repair. Clicking sounds when the A/C turns on and off generally signifies that there could be a relay problem. A rattling noise that occurs when the fan turns the compressor on is due to a failing motor or loose hardware. Should you hear any type of sound that shouldn’t be occurring then it’s best to get in touch with a professional.
