Here Are The Top Reasons Temperature Varies Room to Room

indoor air quality jacksonville fl

Have you ever noticed certain rooms inside of the home are warmer than others? You run your central air conditioning system all day. Shouldn’t every single room be at the same temperature? There are many reasons as to why this may not be the case. This is one area of focus for our energy audit professionals when we come out to homes. We want to see how the house is being cooled and if it is being done in the most efficient way possible. Homebuilders across the entire country are pretty consistent regarding the approaches that they take to households. So many homes are being built across the state of Florida with multiple floors, incredible yards, and lots of living space. One common struggle that many run into, though, is trying to keep that second-floor cool, especially in the summer.

Install Air Conditioning

If you do not have a central air conditioning system running to the second floor, think about adding one. Window units may seem like they will do the job, but they are not likely to have the power to be able to adequately control the temperature on that second level, especially when talking about Florida’s summer heat and humidity.

Our team of air conditioning can help get your home sized for a central air conditioning system in short order. The installation process is easier than you think and you can even have multiple zones installed. This can allow you to set the temperature upstairs lower than downstairs since more cooling is going to be needed to help reduce that second level’s heat.

Turn Down Blinds

Blinds are something that can help a lot as well regarding cooling down the second floor. Close the blinds during the day, even the drapes if you have them. When you do this, you are going to be blocking out the sun as it tries to beat inside of the second floor. This is a useful technique and will help a lot in reducing the heat the floor picks up.

Sizing of the AC Unit

How old is your air conditioning system? When it was initially installed, was it sized appropriately for your residence? So many inexperienced professionals will install an air conditioning unit which is too big or too small for a home. We want to size it correctly for you and can assess where yours stands during one of our energy audit Jacksonville FL jobs. If the unit is not sized properly, it is not going to be able to cool the home to your liking comfortably.

Attic Insulation

When was the last time you checked your attic and the insulation that it has? When you have an attic that is poorly insulated, what you are going to find is that the heat of the attic will come down on you. Ever go up to your attic on a hot day? The attic is usually far warmer than your second floor. When poor insulation exists, that heat is going just to trickle down to the living area.

Closing First Floor Registers

You may have a central air conditioning system that was only installed with one zone. This means you have one thermostat controlling the temperature of upstairs and downstairs. What you can do in this scenario is to close some of the registers on the first floor partially. Doing this will help to increase the airflow to the second floor, making it cooler.

Filter Reducing Air Flow

When was the last time you swapped out the air filter in your system? The air filter of a central air conditioning system is a pivotal component. When it gets dirty, it can downgrade the performance of the whole system overall. A dirty air filter can reduce air flow throughout the ducts. The air flow is needed to cool the home from front to back.

Having a situation where air flow is restricted and reduced due to a weak filter is going to result in some rooms of the home getting more cold air than others. This is one of the most common reasons our energy audit Jacksonville FL professionals find some rooms to be cooler than others.

Air Duct Blockage

Have you ever had your air ducts cleaned? Another common reason as to why some rooms may be cooler than others is due to a blockage in the ducts. Dirt is going to build up in them over the years. If you have a central air conditioning system that has been running all summer constantly think of all that likely built up. A blockage, just like with a worn air filter, can lead to restricted air flow and imbalanced cooling.

Older Windows

Do you have dated windows in your home? Our energy audit Jacksonville FL professionals can help to identify if certain aging windows are detracting away from the ability for your system to cool the home efficiently. It may be a matter of replacing one or all of the windows for the sake of energy efficiency gains.


So many reasons can exist as to why some areas of the home are going to be cooler than others. It could be due to insulation, older windows or your air conditioning system. We can help identify all of that and more with one of our energy audit Jacksonville FL teams. Give us a call today and start to get to the bottom of your cooling irregularity!

Just had an entirely new, full HVAC install done at our old house in Riverside, which was a fairly big job. Brian and... Will did the installation, and were awesome. There was going to be issues leveling the air handler in the attic, so they moved it to a new spot and hung it instead, getting new parts/changing the plan on the fly. We're much happier with this new setup and location of the air handler. I really appreciated this, their professionalism/thoroughness, and flexibility. Brian and Will worked super-hard, and double-checked everything once the job was done. Would use this company more

Two installers here early this morning. Worked all day. Very professional, extremely well mannered and quick to answer... all my questions. They are Dustin and Robert. Both men went above just installing my new unit, they were personable and knowledgeable in what they were doing. I was surprised when I found out these two hadn't been working that long together. They worked extremely well together. I highly recommend this two more

A snake crawled into my outdoor condenser and stopped my 16 year old Trane last week on Thursday. The power surge took... out my blower unit circuit board and the motor. I called J&W and Rob was over within two hours of my call. I was spec'd a new York 17 seer system and it was up and running on Monday. Technicians Jason and Brian arrived promptly and every facet of the installation was thorough. When completed, I would not of even known they were there except they left my garage cleaner! Thanks J&W!read more
