My AC is not cooling enough!

6 reasons why and 6 ways to avoid it!

Summer is here; believe us, you won’t feel the AC is not cooling in the middle of December. It’s these days when you are begging your AC to make your home not feel like a sauna. 

Due to the air conditioning equipment overworking during these months and owners neglecting them, AC units tend to perform worse and not cool enough. In this blog, we will list the most common reasons why this may happen and how to make your AC freeze you this summer!


It may sound dumb, but have you checked your thermostat before reading this? A common mistake (that we all make) is leaving our thermostat settings on HEAT or FAN, leaving us without cool air. Also, thermostats with low batteries may malfunction or display the wrong information. 

Solution: Make sure the mode settings are on COOL. Also, ensure the thermostat has enough battery to work properly. 

Note: It’s important not to abuse the temperature settings on your thermostat. Doing so can lead to higher electricity bills and negatively impact the environment. Maintaining an ideal temperature between 75°F-78°F can keep your home cool and save energy. If you’re still uncomfortable, the issue may lie elsewhere, so keep reading for more tips!

Have you done any maintenance to your HVAC unit in the last few months? If not, and your air conditioner needs to be cooling more, a common issue is having your filters clogged. 

A dirty air filter will limit the air circulating the house, making your AC work harder, spending more energy, and not cooling as much. Especially if you have pets, you should check your air filters monthly to see if they’re too dirty. 

Solution: Some home solutions include brushing and vacuuming it superficially to remove dust and dirt. However, we recommend changing it every 2-3 months to keep your air quality clean and your AC cooling.

Another reason the air conditioner may be unable to cool your home correctly is unintentionally blocking the vents. In many cases, people place rugs, sofas, or other furniture right in front of the house’s air vents, limiting the air that flows through them. 

Solution: Simply rearrange your furniture to ensure free space around all the vents in your home. Clearing the space around the vent will greatly help the air circulate your house and consequently cool more. 

Also, even if there is enough space around the vents, ensure they are open. No matter the space, a closed vent won’t help cool your home. It doesn’t hurt to vacuum the vent periodically if you live in a dusty house to keep the air as clean as possible!


In general, a coil is a series of loops or windings made from a flexible material like wire, rope, or tubing.

Your AC unit uses two primary coils to cool your home: the evaporator and the condenser. They work together through a refrigerant cycle to transfer heat from inside your home to the outdoors.

If your AC’s evaporator coil becomes too icy, it can prevent proper airflow and cooling. This can be caused by low refrigerant levels or restricted airflow. Look at the image below as a reference to where to spot your evaporator coil: 

Solution: Turn off your AC until the ice melts completely, and follow our previous tips to ensure your house’s airflow is fine and it doesn’t freeze again.

If you have tried all the DIY solutions written above and your AC is still not cooling like usual, the issue may lie with your air conditioner’s refrigerant levels. Other ways to notice if your refrigerant levels are low are uncommon hissing noises coming from your AC, finding ice in your unit, and increased electricity bills

Solution: If you’ve checked and found that the refrigerant levels are low, or if you suspect this might be the issue, it’s best to seek the expertise of professional technicians like Home AC Inc [Contact page]. We can provide an accurate diagnosis and effectively resolve the problem.


Leaving your outdoor AC unit unmaintained for long periods can have multiple consequences on your air conditioner performance. Your outdoor unit’s fan and condenser coil can accumulate dirt, leaves, debris, and pollen over time.

This can result in your HVAC system not cooling as much, strain on the compressor, and even system malfunctioning.

Solution: You can check on your outdoor unit periodically and carefully remove any leaves or debris in and around it. We also recommend trimming any vegetation around the AC unit to ensure the debris keeps accumulating. 

If your AC is still not cooling enough, it’s best to leave the deep cleaning to the experts. Contact us at +1 407 724 5615 for a professional deep clean of your outdoor unit. The unit’s many delicate pieces require our expertise.
