Your Air Vents are Closed or Obstructed
If you have closed your air vents, or your vents are obstructed by furniture or upholstery, proper airflow is disrupted. This can most certainly cause some rooms in your home to be hotter than others while placing extra strain on your HVAC system.
Perhaps the most common cause of AC issues is clogged filters. Dirt, pet hair, pollen and dust can clog your filters. When filters get clogged, they begin to restrict the flow of air through your AC. The result is that the AC doesn't cool your indoor air effectively.
Ideally, your AC should run for 15 minutes on nice, warm days. Only on those rare triple-digit temperature days should your air conditioner be running almost all the time. If your AC isn't following this pattern, you could have a problem.
Most air conditioning systems are designed to function with outside temperatures of 100 degrees or less. When temperatures outside become higher than 100 degrees Fahrenheit, the air conditioning system can consume more energy and begin to malfunction or fail.
For the AC to cool the room better, turn off the lights and also exhaust the fan if there's any. Turning off lights reduces the heat level in the room and lets the AC cool better. Turning off exhaust fans in the kitchen and bathroom also helps with better cooling.
So, if one room is always warmer than the rest of your home, the return air vents in the room could be blocked or damaged. When this occurs, cool air is blocked from coming through those vents in your floor or ceiling, resulting in a less comfortable space.
Open the windows and doors to the room
Opening the windows and room door will help increase airflow. This is because it allows air from other rooms or the outdoors to enter this specific room to increase air flow in the room. Proper air circulation in a room is essential.
BLOCKED VENTS
If they're blocked with dirt or debris that accumulates over time, the cool airflow will be reduced, keeping the room warmer than others in your home. Your vents should be cleaned regularly and can even be cleaned by you without hiring a professional.
Place your fan so that it faces the opposite wall from where most of the activity takes place in your space. This approach will drive the air to the surface, where it will bounce off, mingling with the rest of the air and cooling the space.
One of the simplest reasons your AC is only working in certain rooms is vent obstructions. This issue can take three different forms: Closed vents: As you might expect, air can't blow through a closed vent. Check the settings on your vents to ensure they are not preventing air from being released into your room.
Sleeping too hot
“Heat is a huge disruptor for REM sleep,” Dr. Drerup says. With the heat of the room, your body temperature will also rise, thus undoing the sleep initiation process entirely. If your bedroom temperature is above 70° F, it's too hot.
Throughout our research, we've seen sleeping hot be a common problem for people. Even if the room is at the perfect sleep temperature of 60–67 degrees and doesn't change, there are significant fluctuations in relative humidity under the covers; it's often caused by dense bedding products that restrict proper airflow.
Your Ductwork May Need Professional Attention
If you aren't getting sufficient airflow throughout your home when the AC system is running and your cooling bills are rising, your ductwork could be the culprit. It could be leaking that vital cool air into the unconditioned areas of your home.
Problem: Dirty air filter
A clogged and dusty air filter will force your air conditioner to labor in circulating cool air to reach your desired temperature (e.g. your set your thermostat at 73 but the air won't drop below 76).
The primary reason for an AC not cooling below 75 degrees is a dirty air filter. The air filter traps unwanted elements like dust, dirt, and debris, ensuring they don't reach the evaporator coil. In doing so, they may block the filter, causing your AC unit to malfunction.
Do Ceiling Fans Lower the Temperature? A ceiling fan does not actually lower the overall temperature in a room, but it can definitely make a space feel cooler.
The fan won't actually change the temperature of the room, it will just make it feel warmer. Be sure to turn it off when you aren't in the room to save energy. You only need your fan on the lowest setting to get the benefit. Any higher and you might actually feel colder.
Create a cross-breeze
Using two fans to cool down a room rapidly. Beatrice Flores, a home care expert from Living Pristine, recommends placing your two fans in opposite windows to create a cross-breeze. 'This will direct the airflow from both fans across the room, cooling the air quickly,' she says.
You might be low on refrigerant or have a worn out motor or a dirty evaporator coil. Not all AC problems demonstrate themselves with loud sounds or funny odors coming from your system. Some of them simply reduce the AC's ability to run, and all you notice is less cool air in the house.
If your AC is too big, it will cool down your home too quickly, and the cycle will shut off before the drip pan is full. A less than full drip pan will not drain, which will cause that water to evaporate and recirculate inside your house, making it feel humid.
In a 10 ft high room, for optimum cooling, a height of 7-8 ft above the ground is recommended. This will ensure that the cool air spreads well around the room. It also ensures that the air conditioner is not too busy cooling the hot roof which only means higher electricity bill for you.
Air conditioners are designed to make your home's interior temperature no more than 20 degrees below the outdoor measurement. That's quite substantial, even for air conditioners in Phoenix, where temperatures can be sweltering for much of the year.
