7 Solutions to Overcome Insufficient Cooling of ACs

Air Conditioners

Air conditioners are essential appliances, especially during hot summer months, for maintaining a comfortable and cool indoor environment. However, they can sometimes face issues such as insufficient cooling. ALP Heating, a trusted provider of HVAC services, explains in detail the common causes of insufficient cooling in air conditioners and how to address them.

Clogged Air Filters

If you’re experiencing insufficient cooling from your air conditioner, it’s likely that your air filters are clogged. Unfortunately, this is a common issue in many households. Over time, dust, dirt, and other debris accumulate on the air filters, restricting airflow and reducing the cooling capacity of the unit. This means that your air conditioner has to work harder to cool the air, leading to higher energy bills and decreased efficiency.

At ALP Heating, we recommend changing your air filters every three months to ensure optimal cooling efficiency. Not only will this extend the life of your air conditioner, it will also help reduce your energy bills and improve the overall air quality in your home. If you’re not sure how to do this, our experienced HVAC technicians can help. We can inspect your air filters and replace them if necessary, so you can enjoy the cool air you deserve.

Clogged air filters are a common issue, but they can easily be prevented. Regularly cleaning or replacing your air filters is an easy and cost-effective way to keep your air conditioner running efficiently. If you’re not sure how to do this, you can always call an experienced HVAC technician from ALP Heating. We can help you identify any problems and provide the appropriate solutions so you can enjoy a comfortable and cool home.

Low Refrigerant Levels

If you’re experiencing insufficient cooling, then low refrigerant levels are almost certainly to blame. Refrigerant is the lifeblood of your air conditioner; it absorbs heat from the indoor air and releases it outside. If the levels are low, then the air conditioner won’t be able to adequately cool your home.

Low refrigerant levels can be caused by a number of factors, but the most common culprits are leaks or improper installation. Leaks can be hard to detect, so it’s best to have a professional HVAC technician from ALP Heating take a look. We’ll be able to diagnose the issue and repair any leaks if necessary.

We understand how uncomfortable it can be when your air conditioner isn’t performing as expected. That’s why we strive to provide swift and reliable service. With our expertise and experience, you can rest assured that your air conditioner will be running smoothly again in no time.

Dirty Condenser Coils

If your air conditioner is struggling to cool the indoor air, it could be due to insufficient cooling caused by dirty condenser coils. Over time, dirt and debris can accumulate on the outside unit’s condenser coils, reducing their ability to dissipate heat effectively. The condenser coils are responsible for releasing the heat absorbed by the refrigerant into the outdoor air, so if they’re covered in dirt, your AC won’t be able to do its job. We strongly recommend regular maintenance, including cleaning the condenser coils, to keep your air conditioner running smoothly and efficiently. A clean condenser coil will ensure that your air conditioner is able to maintain the desired temperature in your home, so make sure your HVAC system is getting the proper care it needs.

Inadequate Insulation and Sealing

Inadequate insulation and sealing around doors and windows can cause your AC to work harder and longer to keep your home at a comfortable temperature. Not only does this lead to higher energy bills, but it can also make your home feel stuffy and uncomfortable.

The best way to prevent this is to make sure all the windows and doors in your home are properly sealed and insulated. All cracks, gaps, and poor insulation should be filled in, and if necessary, you should upgrade or add insulation to help your AC run more efficiently.

However, if you’re already experiencing insufficient cooling, there are a few other things you can do. Make sure your air filter is clean and replace it as needed. It’s also important to keep your AC unit serviced regularly to ensure it’s in tip-top condition.

Incorrect Thermostat Settings

As an HVAC expert from ALP Heating, I’m here to tell you that if your cooling isn’t up to par, the likely culprit is your thermostat settings. Make sure that it is set to ‘cool’ and not ‘fan only’ mode. If it’s already set to ‘cool’ mode, check the temperature. If it’s too high, the AC may struggle to keep the desired temperature. Additionally, if the thermostat is set to ‘auto’ mode, the fan may be running continuously, resulting in insufficient cooling.

To ensure that your thermostat settings are correct, it’s important to check the accuracy of the display. If the true temperature doesn’t match the reading on the thermostat, there could be a problem with the calibration. It’s also important to make sure that the thermostat is located in an appropriate place. If it’s too close to a heat source, such as an appliance or a window, the thermostat may not be able to accurately measure the temperature.

If you’re still having problems with insufficient cooling, it could be a sign of a larger issue with your AC unit. If that’s the case, it’s best to call an HVAC professional to take a look and help you with all your cooling needs, from thermostat settings to major repairs.

Improperly Sized AC Unit

An improperly sized air conditioner can cause major issues. When your AC unit is too small, it simply doesn’t have the power to cool your space adequately and it’ll leave you feeling hot and bothered during the summer. On the other hand, if the air conditioner is too large, it’ll cause the unit to cycle on and off more frequently, leading to inefficient cooling and higher energy bills.

Now, I know what you’re thinking: how do I know the right size air conditioner for my home? The best way to ensure you get the right size unit is to consult a professional HVAC technician from ALP Heating. Our technicians can accurately assess your home’s cooling needs and recommend the perfect system for your needs.

At ALP Heating, we take a comprehensive approach to air conditioning installation. We start by assessing your home’s layout, taking into account the number of windows, insulation, and other factors that can affect your cooling needs. We then calculate the size and number of air conditioners you need to keep your home comfortable.

We also take into account your budget and lifestyle. If you’re looking to save money, we can recommend energy-efficient systems that will save you money in the long run. If you want a system that can handle extreme temperatures, we can recommend powerful units that can keep your home cool even on the hottest days.

In short, if you’re looking for an air conditioner that will keep your home comfortable without breaking the bank, make sure to consult an HVAC technician from ALP Heating. We’ll help you find the perfect system for your home and ensure that you never have to worry about insufficient cooling again.

Obstructed Air Vents

Ah, and let me remind you that blocked air vents can cause significant problems for your heating and cooling system. It’s important to keep the area around the vents clean and clear of obstructions to ensure that the airflow is not restricted and your system operates at its optimum level.

When air vents are blocked, your system has to work much harder to move air in and out of your home, leading to insufficient cooling and poor energy efficiency. This can result in higher energy bills, as well as wear and tear on your system.

Plus, blocked air vents can cause the air in your home to become stale and stuffy as it isn’t getting circulated properly. Not only is this uncomfortable, but it can also lead to health problems related to air quality.

To keep your heating and cooling system running smoothly and efficiently, it’s important to regularly check the vents to make sure that they are not blocked by furniture, curtains, or other objects. This will help to ensure that your system is operating optimally and that your home is a comfortable and healthy environment.


Insufficient cooling of AC is a common issue that can result from various factors. Regular maintenance and inspection can help you identify and address these issues early, ensuring optimal cooling efficiency and prolonging the life of your air conditioner. If you need assistance with diagnosing or resolving any air conditioner issues, the experienced team at ALP Heating is ready to help.
