PTAC units are placed within a sleeve and grille in the back. However, over time, the sleeve and the unit have a gap between the sleeve and the wall. Insulation wears out when the unit is pulled in and out of the sleeve. Or the cut in the wall can be wider than the sleeve. There are many reasons for a gap being created and most of the time, the gap is not visible.

What can air gaps cause?

1. Poor air circulation: Air gaps can create pockets of still air that don’t move, which can prevent the PTAC unit from circulating air effectively.

2. Inadequate ventilation: Air gaps can interfere with the natural flow of air, which can reduce the amount of fresh air that enters the space. This can lead to inadequate ventilation, which can cause poor indoor air quality.

3. Reduced efficiency: Air gaps can increase the amount of time it takes for air to reach the PTAC unit, which can reduce its efficiency and cause it to use more energy to run.

4. Increased risk of condensation: When air gaps are present, cold air can get trapped in the space, leading to an increased risk of condensation, which can cause water damage to the walls and ceiling.

5. Reduced comfort level: Air gaps can prevent the PTAC unit from providing the desired temperature, reducing the overall comfort level of the space.

How to prevent air gaps?

1. Install weather stripping between the PTAC unit and the wall. This will help seal any air gaps and keep any unwanted air from entering the room.

2. Make sure the PTAC unit is level when installing it. This will help ensure the unit is installed properly and will also help prevent any air gaps from forming.

3. Install a drip edge or a flashing around the unit to help keep water away from the unit and to also help seal any potential air gaps.

4. Add insulation around the PTAC unit. This will help to keep the air inside the room and help reduce any air gaps.

5. Check the seals around the unit regularly and replace any that are worn or damaged. This will help ensure the unit is sealed properly and will help reduce air gaps.

6. Check for any small cracks and gaps around the unit and seal them with caulk or expanding foam. This will help to reduce air infiltration and keep the unit sealed properly.

7. Make sure the filters in the unit are regularly changed. This will ensure the unit is running properly and that air is not leaking out through the filters.

Pro Tips when installing insulation

1. Make sure the insulation is an appropriate thickness and R-value for the climate and climate zone you are in.

2. Make sure all gaps are sealed to prevent air infiltration.

3. Make sure the insulation is installed properly and kept away from any electrical components.

4. Make sure the insulation is kept away from the fan motor and doesn’t block any airflow.

5. Make sure the insulation doesn’t come into contact with any exhausts or ducts.

6. Make sure to inspect the insulation after installation to ensure it is secure and not damaged.

7. Make sure to use fire-resistant insulation material, especially if the PTAC unit is located near combustible materials.

8. Make sure the insulation is installed in a manner that allows for proper ventilation.

Windows

What insulated windows overtime?

Insulating windows is another important aspect of your rooms. Insulation can wear down over time due to exposure to moisture, heat, and sunlight, as well as settling and compression. Moisture can cause the insulation fibres to break down, while heat and sunlight can cause the insulation to become brittle over time. Settling and compression can cause the insulation to become less effective, reducing its ability to insulate effectively.

Why is it important to insulate windows?

Insulating windows is important because it helps to reduce energy loss and keep your home more comfortable by maintaining a consistent temperature. Insulating windows also help to reduce noise from outside and block out UV rays from the sun that can cause fading of furniture and flooring. Over time, the insulation will wear down and become less effective, leading to increased energy loss and a more uncomfortable home.

How to insulate windows?
1. Install window insulation film: Window insulation film is an easy and effective way to reduce heat loss through your windows. It’s a plastic sheet that’s applied directly to the window, and it’s held in place with double-sided tape or an adhesive.

2. Install storm windows: Storm windows are additional window that fits over your existing window and creates a layer of insulation. It’s a great way to reduce heat loss and can be installed relatively easily.

3. Install window insulation panels: Window insulation panels are rigid foam or plastic panels that fit directly in the window frame. They come in different shapes and sizes to fit most windows and are a great way to keep the heat in and the cold out.

4. Caulk and weatherstrip: Caulking and weatherstripping are inexpensive and simple ways to improve the insulation around your windows. Caulk is a sealant that’s applied to the edges of your window, while weatherstripping is a rubber or foam strip that’s applied around the edges of the window to seal out drafts.

5. Install window shades or drapes: Installing window shades or drapes can also help
