Whole-Home Air Sealing in
Phoenix West Valley
Uncontrolled air leakage can drive up energy bills, pull in dust and attic air, and make rooms harder to keep comfortable. Sharp Home Solutions uses diagnostic testing to locate and prioritize the air leaks that matter most — so improvements are targeted and effective.
Based on thousands of home performance evaluations across the Phoenix West Valley.
Why Air Sealing Matters
Air leaks are one of the most overlooked performance problems in Arizona homes. Gaps around attic penetrations, top plates, duct boots, and hidden bypasses allow unconditioned air to enter while conditioned air escapes — what many homeowners experience as drafts. Over time, this increases energy use, reduces comfort consistency, and contributes to dust and indoor air quality concerns. Attic air leaks have a big negative impact on insulation performance.
Our Air Sealing Process

Test & Identify
We use blower door testing and visual inspection to locate the air leakage pathways and focus where it matters most.

Targeted Air Sealing
Priority leakage areas in the attic and home are professionally sealed to reduce unwanted air movement.

Verify Improvements
Post-work testing helps confirm reductions in specific air leakage paths and overall home performance improvements.
Air leakage is worth checking if you’re dealing with:
- Allergies are as bad or worse inside the home than outside
- Drafts that can be felt in the home
- Utility bills are high without a clear reason
- The home feels dusty, or filters load up fast
- You notice unknown smells
- Dust levels change noticeably throughout the year
Air leaks are only one possible cause — but it’s one of the most important to measure and rule in or out.
What Air Leakage Testing Often Reveals
In many homes we test, a noticeable amount of conditioned air escapes into the attic, wall cavities, and other hidden pathways. These leaks often go unnoticed but can drive higher energy bills, uneven temperatures, dust infiltration, and reduced overall comfort. Just as important, without proper air sealing, insulation cannot perform to its rated effectiveness and may deliver disappointing results. Testing helps pinpoint where improvements will have the greatest impact.
Common Leakage Areas in West Valley Homes
While every home is different, many houses throughout the West Valley share similar air leakage patterns. Based on our field testing experience, the most common problem areas often include:
• Attic penetrations and top plates
Openings around wiring, plumbing, and framing allow hot attic air to enter the home.
• Duct boots and ceiling register connections
Gaps where ducts meet the ceiling frequently leak conditioned air into the attic. Worse is when air is pulled from the attic into the home through pressure imbalances.
• Drop soffits and mechanical chases
Common in many Sun City and surrounding homes, these hidden pathways can move large amounts of air.
• Knee walls and open wall cavities
Often found in Peoria and similar areas, these spaces can connect attics directly to living areas.
• Older recessed lighting and attic access points
Unsealed fixtures and hatches can act like small chimneys for unwanted air movement.
Because these issues are typically hidden, proper testing is the most reliable way to identify which leaks matter most in your specific home.
When Air Sealing Is Often the Right Solution
- Air leaking to the outside, attic, or wall cavities
- Rooms that struggle to stay comfortable
- Dust being pulled into the home
- Long run times or higher-than-expected energy use
- HVAC equipment turns on shortly after cycling off
When Additional Improvements May Be Needed
- Missing, poorly installed or inadequate insulation
- Oversized/Undersized HVAC equipment
- Duct leakage is also a contributor (see our duct leakage testing and sealing service)
- Significant duct design or airflow problems
This is why testing comes first — so improvements are matched to what your home actually needs.
If duct leakage is suspected, we may also recommend targeted duct sealing improvements.
Sharp Home Solutions provides whole-home air sealing services throughout the Phoenix Metro and West Valley, including Peoria, Sun City, Sun City West, Surprise, and Buckeye.
Whole-Home Leakage Testing & Professional Sealing
Find out whether air leakage is contributing to comfort, air quality, or energy problems in your home — and what steps will actually improve them.
The goal is improved comfort, healthier living conditions, and better efficiency. In some situations, utility rebates may also be available and will be reviewed as part of your home evaluation.
Professional whole-home leakage testing starts at $99
for most single-system homes.
This includes blower door testing, duct leakage testing, airflow/static pressure evaluation, attic insulation inspection, and visual duct inspection.
Testing helps identify whether duct leakage, airflow design, insulation, or system performance is contributing to your comfort or efficiency concerns.
Homes with multiple HVAC systems may require additional testing. All findings and recommendations are reviewed before any repair work is discussed
