Why Won’t My AC Evenly Cool My House?


As the hot days of summer continue, you may feel as though your home’s not getting as cool as it should be. There are many reasons for this. Sometimes, it’s just too hot, and that means even the best air conditioners may struggle to keep the home cool. Yet, most of the time, it is because of inefficiencies or problems with your AC that you are tossing and turning at night or struggling during the day with hot conditions. It’s always beneficial to turn to a professional for air conditioning repair in New Braunfels, TX.

Common Reasons Your Home Is Still Too Hot

If your home’s air conditioning is not cooling properly, it may be time to look closely at what could be going wrong. Here are some of the most common reasons for improper or inefficient cooling.

#1: AC Is Too Old

Most air conditioners last 10–15 years. Over time, even the best systems begin to wear down, and that can lead to the system being ineffective at cooling the home consistently. If the air conditioner is older than this, its components are likely worn significantly, limiting its ability to perform well. That means it may be time to invest in a new model.

#2: AC Is Underpowered

Air conditioners must be sized properly to fit the home. One that is too large for the home is going to short cycle—turn on and off—numerous times before it can reach the proper level. More commonly, an air conditioner is too small. That means that, even though it is running nearly nonstop throughout the day, it may not be able to completely cool down the home. It just does not have the power and performance to do so.

Even with air conditioning repair, it may be better to replace your system in these situations as it can directly contribute to home energy consumption.

#3: Its Filter Is Clogged

Each month during the summer months, remove and replace the air conditioning filter. That is essential to ensuring that the system is able to pull in enough air quickly and easily. As the summer heat draws on, you’ll notice a drop in efficiency if your home’s air conditioner’s air filter is clogged.

#4: Faulty Thermostat

Sometimes it’s not the air conditioner but the thermostat that’s the problem. If your thermostat is not working properly, such as not sensing temperatures accurately, that means the air conditioner cannot work properly. The thermostat tells the AC when to turn on and off. Replacing the thermostat (especially if it is more than 5 to 7 years old) may be critical to getting your system working at its best.

#5: Leaky Air Ducts

A more significant problem comes from having leaky air ducts, which are the paths through the home where conditioned air travels. If there are too many holes or worn areas, that will cause a significant loss. You may need repairs from a technician to fix this.

#6: Refrigerant Loss

If your system is blowing but the air coming through is not cool, it could be due to refrigerant loss. This is what helps to create cool air. It’s best to allow a trained professional to take a closer look at this potential concern.
