Uneven Temperature Distribution: Because of reduced airflow, rooms farther from the HVAC system or rooms connected to ducts with dirty filters, may receive less warm air. This leads to uneven
You'll have to treat the room separately, with a split unit. An alternative solution would be to use a combination of mechanical cooling (exhaust fan), via cooler outdoor air, and a split unit, for warmer days.
Several factors can cause some houses to feel colder than others in the same area, including: insulation quality, air leaks, window efficiency, HVAC system size and functionality, ductwork condition, sun exposure, house orientation, and the age of the home.
Closed vents—Closed vents in rooms can cause them to be hotter than other rooms. Open windows—Your conditioned air can flow out of open windows, leaving uneven temperatures in your home. Air duct issues—If you have any kinked or crushed supply ducts, certain rooms won't get enough air.
If one room in your house is colder than the rest, the first things to inspect are the heating vents, ductwork and thermostat readings. Inspections of this sort should be performed at least once yearly. If your room is cold you might need to: Check heating vents.
Your AC might be stuck at 75 due to various reasons like clogged filters, refrigerant leaks, or the wrong unit size. It's best to have a professional diagnose and fix the issue.
Locating the Reset Button
Remove the thermostat cover by either snapping it off or unscrewing it, depending on the model. Most modern thermostats will have a clearly marked reset button inside the panel. It's usually small and recessed, so you might need a pointed object like a paperclip to press it.
Check for Proper Heat Flow
When airflow is poor, the room can't heat up properly, and you end up with that one cold room in an otherwise warm house. Regular HVAC maintenance can help ensure your system works efficiently throughout the home.
Create cross ventilation by opening windows on opposite sides of the house to promote air circulation. Close curtains, blinds, or shades during the hottest parts of the day to block out direct sunlight and heat. Utilize exhaust fans in bathrooms and kitchens to remove hot air and humidity from these spaces.
If you've got a room or two that's colder or hotter than others in your home, then you have one (or both) of these two problems: Air balancing/airflow issues. Losing/gaining too much heat in that room.
Foam strips, draft excluder brushes and chimney balloons all prevent cold air from rushing into your home from the gaps around windows, doors, letter boxes and other holes in the building fabric. These are easy to fit as they come with self-adhesive strips. They are cheap to buy and make a noticeable difference.
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 being disrupted. This can most certainly cause some rooms in your home to be hotter than others, while placing extra strain on your HVAC system.
If a person's body temperature strays too far from 98.6°F (37°C), they can develop hyperthermia or hypothermia. Various factors can contribute to this, including infections, extreme weather, medications, and other health conditions. Thermoregulation disorders can be a medical emergency.
Closed or blocked vents cause some rooms to feel hot while others feel too cool because they receive too much air conditioning. Ductwork Leaks: Leaks in the supply ducts cause uneven cooling from your air conditioner in the areas of your home these ducts serve.
What should my AC be set at if it's 90 degrees outside? If the outdoor temperature is 90 degrees, it's recommended to set your thermostat between 75-78 degrees.
Clean the Thermostat
Sometimes, when the room temperature doesn't match the thermostat setting, the problem could be dirt buildup on its interior parts. A dirt coating around the inner components may create excess heat and cause the thermostat to give the wrong readings.
Most central air conditioners can cool a moderate-sized (3 to 4 bedroom) home by about 5 degrees every 3 hours. This means while it can take no more than a couple hours to lower the temperature to a comfortable range in the fall or autumn, it can take much longer in the summer.
