Optimizing Your HVAC System for Arizona Summers

Different Types of Air Filters and Their Benefits
August 20, 2024
Insulation plays a critical role in maintaining the comfort and efficiency of your home. By creating a barrier between the temperature inside your home and the temperature outside, insulation helps keep warm air in during the winter and cold air in during the summer. Insulation not only makes your HVAC system run more efficiently but also extends its lifespan and lowers your energy bills. Did you know that in houses without proper insulation, energy costs can be as much as 40 percent higher than in homes with proper insulation?
The effectiveness of insulation is measured by its R-value, which indicates how well the insulation resists heat flow. In Arizona, the recommended R-value is R38. Let’s explore the various types of insulation available, their benefits, and how much you need.
Blown-In Attic Insulation
Recommended Thickness: 13-14 inches, depending on joist configuration.
Blown-in insulation is a loose-fill insulation that is blown into the attic and walls with an electric blower. Mountain Peak Air uses blown-in insulation made from recycled paper products, though it can also be made from fiberglass, cellulose, or mineral wool. This type of insulation is ideal for existing, closed-up walls because it doesn’t require ripping out siding or interior drywall to access wall cavities. Blown-in insulation is a mid-range priced option that provides excellent coverage and can fill small gaps and hard-to-reach areas.
Spray Foam Insulation
Recommended Thickness: 5-9 inches, depending on joist configuration.
Spray foam insulation is an air-seal plastic material sprayed on walls, roofs, and all contoured surfaces. Made of two liquids (ISO and resin) mixed together, it sets within seconds when sprayed, creating a foam that provides a strong barrier against heat flow. Spray foam insulation not only insulates but also reduces the amount of dust, allergens, and pollutants entering your home. It can be trimmed, painted, or stained, making it a versatile option for various applications.
Other Insulation Options
Batts: Batts are pre-cut sections of insulation blanket, usually made of fiberglass but are also available in other materials. Batts are affordable and suitable for DIY homeowners. They are placed between framing studs and joists, making them ideal for unfinished homes.
Rolls: Similar to batts but not pre-cut, rolls offer continuous lengths of insulation, reducing the opportunity for gaps. They are also affordable and DIY-friendly, best used in unfinished homes.
How Much Insulation Do You Need?
The amount of insulation you need depends on your home’s current insulation status and the specific areas you want to insulate. For blown-in attic insulation, 13-14 inches is generally recommended. For spray foam insulation, 5-9 inches is sufficient. It’s essential to consider your home’s unique needs and configurations to determine the exact amount.
Proper insulation is vital for maintaining a comfortable and energy-efficient home. Whether you choose blown-in insulation, spray foam, or another type, ensuring you have the right amount and proper installation is key.
