Installing insulation for your air conditioner is an important step in ensuring maximum efficiency and cost savings. Spray foam insulation is a popular choice due to its versatility and ease of installation, as it has a high operating temperature and excellent moisture resistance. It is suitable for both hot and cold climates, and installing it on windows is a prerequisite for saving on heating costs during the winter. Fortunately, insulating your air conditioner from your window is less expensive and less time consuming than other methods. The maximum thermal performance or R-value of the insulation depends on a suitable installation.
Homeowners can install some types of insulation, such as blankets, boards, and materials that can be placed in place. Liquid foam insulation materials can be poured, but require professional installation.
Radiant BarriersRadiant barriers are more effective in hot climates, especially when cooling air ducts are located in the attic. Studies show that radiant barriers can reduce cooling costs by 5-10% when used in a hot, sunny climate. Reducing heat gain may even allow for a smaller air conditioning system.
However, in cold climates, it is often more cost-effective to install more thermal insulation.
Air DuctsAir ducts can be very hot, above 66°C (150°F), so insulation may be justified for safety reasons or if heat loss from the exhaust gas pipe is considered harmful to space. Air duct installation is usually carried out by HVAC contractors, who manufacture the insulation in their workshops or on workplaces. Placing the insulation outside has the added advantage of containing the thermal mass of the blocks inside the conditioned space, which can moderate indoor temperatures. This material contains approximately 80% air by volume and has been commonly used in Europe since the late 1940s. Sealing and insulating the air will improve these results, allowing you to get a properly sized unit that will be more energy efficient and ultimately make your home more comfortable.
InstallationOn the outer surfaces of the ducts, they can install the insulation by impaling it onto solder pins and securing it with quick clips or washers.
The outer insulation of the concrete block wall places the mass inside the conditioned space, which can moderate indoor temperatures.
