2nd Floor Poor Circulation Ac

Hot air rises so the second floor is naturally going to be warmer.
2nd floor poor circulation ac. By replacing the register covers with register fan units more cold air is forced out of the upstairs ducts. Depending on the size you get you can spend as little as 150 or a good unit and less than 20 each month to run it every day. Without this second floor return air system the heavy cool air being discharged from the supply ducts in each room can t do its job. However when the thermostat senses that the temperature on the main floor is the temperature your hvac system has been set for it will turn off the ac.
Air circulation in homes which are older and or in poorly designed newer ones equipped with a central forced air system might be compromised because they do not have an air return port installed on the second floor. It often floats along in a layer near the floor. Window ac units are quite affordable too. This is one reason why your first floor is so much cooler than the second floor.
It doesn t matter how much you run the air conditioning system during the summer that second floor will always stay much hotter than the first. If they still are warmer then the downstairs rooms close the downstairs vents more. Check the temperature of the second floor rooms. It is unusual but certainly possible that some ducts have become disconnected during construction or renovation of the home.
Of course this means that your second floor has not yet sufficiently cooled. Hot air rises and cold air sinks. To transport the air throughout your home your hvac system uses ducts of various shapes sizes and configurations. It eventually cascades down the stairwell to the first floor.
Keeping upstairs rooms adequately cooled in summer puts the homeowner up against a basic fact of physics. Ensure that the air conditioning unit is on and wait one hour. The second location to inspect when a low volume of air is detected at several registers in a home but not others are the ducts. Most ducts are held in place with small screws duct tape or brackets.
How to improve central air on upper floors. Set your air conditioner to run the fan continuously. Uses of ceiling fans electric fans and leaving doors open to increase circulation also have some effect. If the air conditioner is big enough to cool the whole house then air circulation is most likely the trouble.
On the bright side you should see much better air flow throughout the house and hopefully fix where you have no air coming out of vents in one room or multiple rooms. This draws the warm air from the upstairs through the air return and circulates it through the rest of the house leveling the temperature.
