How to Keep Mobile Home Cool During Summer

Are Manufactured Homes Energy Efficient?

In the scorching summer heat, keeping your mobile home cool and comfortable is essential. Excessive heat can wreak havoc on mobile homes, leading to problems such as increased energy consumption, discomfort, and potential damage to appliances and furniture.

Effective cooling solutions are essential to maintaining a comfortable home and safeguarding financial investment.

When Summer Comes Around, Why Do Mobile Homes Feel So Hot?

Mobile homes tend to get exceptionally hot during summer due to several factors. One of the primary reasons is their construction and insulation, which differ from traditional homes.

Mobile homes often have thinner walls, less insulation, and fewer barriers to heat transfer. As a result, they absorb heat more quickly and struggle to maintain cooler temperatures.

Additionally, mobile homes may lack features like double-pane windows that provide better insulation against heat penetration.

Easy Methods to Reduce Heat in Your Mobile Home

1. Use your outdoor grill
Take advantage of summer weather and reduce indoor heat by using your outdoor cooking grill. Preparing meals outside prevents the added heat from stovetops and ovens, which can quickly raise the temperature indoors.

Outdoor grilling also adds an enjoyable element to your summer meals. To ensure safe and efficient grilling, follow proper safety guidelines, maintain a clean grill, and use appropriate fuel sources.

2. Close your doors
Keeping your doors and windows sealed is crucial in preventing hot air from infiltrating your mobile home. Proper weatherstripping and sealing gaps effectively minimize the amount of heat that enters.

Check for any cracks around doors and windows and address them promptly. Weatherstripping materials and caulking can help create a tight seal, keeping the cool and hot air inside.

3. Use fans wisely
Strategic placement of fans can significantly improve air circulation within your mobile home. Consider using ceiling fans, window fans, or portable fans in critical areas to facilitate the movement of cool air.

Ceiling fans help distribute cool air throughout the room, while window fans can draw in fresh air from outside during cooler parts of the day. Portable fans can be positioned strategically to create a refreshing breeze.

Experiment with fan placements to optimize airflow and keep your mobile home comfortable.

4. Use blackout curtains
Blackout curtains are excellent for blocking sunlight and reducing heat transfer through windows. Invest in quality blackout curtains that fit your windows properly.

When installed correctly, these curtains can significantly reduce the heat entering your mobile home, keeping it cooler during hot summer days. Choose curtains with a high Thermal Resistance (R-value) for optimal insulation against heat.

Installing blackout curtains is a simple and effective way to create a cooler indoor environment.

5. Reduce humidity with simple hacks
Humidity can make the air feel even hotter, making your mobile home uncomfortable. Implement practical measures to reduce humidity levels. Consider using dehumidifiers to extract excess moisture from the air.

Additionally, taking shorter showers, using exhaust fans in the bathroom, and promptly fixing any plumbing leaks can help minimize humidity buildup. Reducing humidity create a more comfortable and cooler living space.

6. Open windows at night
Take advantage of cooler evenings and promote natural ventilation by strategically opening windows. When the temperature drops outside, open windows on opposite sides of your mobile home to create cross-ventilation.

This allows fresh, cool air to enter and pushes out the warmer air from the inside. However, ensure your windows have proper security measures to prevent unauthorized access. Use window locks and consider adding window security film for added protection.

7. Weather-proof your windows
Windows are a significant source of heat transfer. Properly insulating them can significantly reduce the heat entering your mobile home. Consider applying the window film, which reflects heat and blocks harmful UV rays.

Weatherstripping and caulking effectively seal gaps around windows and prevent hot air infiltration. Weather-proofing your windows creates a barrier against the summer heat, keeping your mobile home cooler.

8. Create a network of shade
Shading the exterior of your mobile home can provide significant relief from the heat. Awnings, shade sails, or planting trees can create a network of shade that blocks direct sunlight from reaching your home.

A well-designed shading system can reduce solar heat gain and help maintain lower temperatures indoors. Consult a professional or research to determine the best shading options for your mobile home.

9. Replace incandescent lights with LED bulbs
Using incandescent lighting in your mobile home can significantly raise the temperature inside. Replacing them with energy-efficient LED bulbs can minimize the heat generated by lighting fixtures.

LED bulbs produce less heat and consume less energy, resulting in additional cost savings. Transitioning to LED lighting is a simple yet effective step toward keeping your mobile home cooler during summer.

10. Use a Cool Roof Coating
Consider installing a cool roof coating on your mobile home to improve its cooling effectiveness. Cool roof coverings reflect Light and heat, lowering the amount of heat the roof takes in.

Two popular options for mobile homes are aluminized asphalt roof coating and elastomeric roof coating. Aluminized asphalt roof coating provides excellent heat reflectivity, while elastomeric roof coating offers superior flexibility and durability.

A cool roof coating can lower indoor temperatures and reduce cooling costs of your MCM home.

How Big of an Air Conditioner Do I Need for a Mobile Home?

Choosing the right size air conditioner for your mobile home is crucial for efficient cooling. Several factors need to be considered when determining the appropriate AC size, such as the size of your mobile home, the number of rooms, insulation quality, and local climate conditions.

An air conditioner that is too small will need to be more significant to cool your mobile home adequately, while one that is too large may result in frequent cycling and energy wastage.
