Trusted Home Energy Audit for Morgan Hill Homeowners
A home energy audit in Morgan Hill typically costs $350-$850 for a full diagnostic package and takes 2-4 hours on-site. Most homeowners receive their written report with blower-door numbers and thermal images within 48 hours. Call (669) 280-8103 to schedule - we answer live, 24/7, and hold to our written price before any work starts.
We’ve been sealing and insulating homes under The Haven Standard since 2016, and we’ve learned that guessing about energy loss costs more than measuring it. A proper audit in Morgan Hill isn’t a clipboard walkthrough. It’s a pressurized test, a thermal scan, and a documented record of exactly where your conditioned air is escaping. The homes we see in Madrone and the older ranch-style builds along East Dunne Avenue often test at double the leakage they should, with homeowners paying for heating and cooling that never stays inside. Our crews have run blower-door tests on over 9,000 homes since 2016, and we publish the before-and-after numbers on every job so you can verify what changed. Same-day scheduling is available in Morgan Hill when you call (669) 280-8103.
What Our Home Energy Audit Service Includes
Blower Door Test
A blower-door test is a pressurization reading that shows, in one number, how much air your building envelope is losing. We mount a calibrated fan in an exterior door, depressurize the house to -50 Pascals, and measure the airflow in CFM50 - cubic feet per minute at that standard pressure. In Morgan Hill, we regularly see readings above 3,500 CFM50 in homes built before 1990, especially in the Paradise Valley and San Martin areas where original construction often skipped top-plate sealing. At Topside Attic Insulation Morgan Hill, we run this test before any air-sealing work and again after, so you have documented proof of the performance change. The number goes on your report. No estimates, no guesses.

Thermal Imaging Inspection
Thermal imaging - infrared camera scanning - reveals temperature differences in walls, ceilings, and floors that indicate missing insulation, air leaks, or moisture intrusion. We use FLIR cameras rated to detect differentials as small as 0.05°C, which matters in Morgan Hill’s mild climate where subtle leaks don’t announce themselves with obvious drafts. During Santa Clara County’s cool mornings, we often find thermal bypasses around recessed can lights in homes near Anderson Lake, and missing insulation batts behind kneewalls in the older two-story builds off Cochrane Road. Our technician walks the house with you, pointing out what the camera sees, and every thermal image is saved to your Documented Photo Record.

Insulation Inspection
Insulation inspection means measuring what’s in place, identifying what’s degraded, and flagging where it was installed wrong - compressed batts, gaps around framing, or moisture-stained material that needs removal. In Morgan Hill, we find a lot of original fiberglass batts in attics that have settled below the joist tops, and blown-in GreenFiber or Owens Corning that’s been disturbed by rodent activity or previous work. We check R-values against current Title 24 requirements for Santa Clara County climate zones, and we note whether the insulation was installed before or after air sealing. If it went in before the leaks were sealed, it’s doing less than half the job it could. Our report tells you exactly what you’ve got and what it should be.

Duct Leakage Test
A duct leakage test pressurizes your HVAC duct system and measures how much air escapes to unconditioned spaces - attics, crawl spaces, wall cavities. We seal the registers, connect a calibrated fan to the return, and measure total leakage and leakage to outside separately. In Morgan Hill homes with original flexible ductwork from the 1980s and 1990s, we commonly find 25-40% total leakage, with 15-25% of that going directly to the attic. That’s conditioned air you’re paying to heat or cool, dumped into a space that doesn’t need it. Our test follows California Energy Commission protocols, and the results go in your written report alongside recommended sealing or replacement options.

Brands We Service for Home Energy Audit

We’ve audited homes with Owens Corning insulation systems throughout Morgan Hill’s newer developments, including the neighborhoods off Vineyard Boulevard and the builds near the Morgan Hill Community Park. Their AttiCat blown-in and Foamular rigid board products are common in homes from the 2000s, and we know the density and coverage specs that let those materials perform to their rated R-values. We’ve also worked extensively with GreenFiber cellulose, particularly in the older ranch homes near downtown Morgan Hill where homeowners chose blown-in cellulose for its air-sealing properties and recycled content. We understand how GreenFiber settles over time and what that means for your effective R-value.
Johns Manville and Knauf products show up regularly in Morgan Hill’s custom builds and in retrofit jobs where contractors specified formaldehyde-free batts or mineral wool for fire-rated assemblies. We inspect these materials for proper installation - no gaps, no compression, no vapor-barrier misplacement - and we can tell you whether what’s in your walls matches what was specified. Whether you have Owens Corning, GreenFiber, Johns Manville, Knauf, or any other make, we can help. Our audit reports the condition and performance of what you have, not the brand loyalty of who installed it.
Signs You Need Home Energy Audit Right Now
- Your PG&E bill spikes in summer or winter without explanation. Morgan Hill’s cooling degree days have increased over the past decade, but a sudden jump of 30% or more usually means conditioned air is escaping faster than your system can replace it. An audit pinpoints whether the loss is through the attic, the ductwork, or the crawl space.
- Some rooms never reach the thermostat setting. In homes near East Foothills or the hilly sections of Alum Rock, we see this constantly - the master bedroom runs five degrees hot in July, the back office is cold in January. It’s almost never the HVAC unit. It’s almost always a duct leak or missing insulation that a blower-door and thermal scan will expose in under an hour.
- You feel drafts even with windows and doors closed. Air moving through outlets, baseboards, or can lights isn’t mysterious. It’s the stack effect pulling outdoor air in through the bottom of your house and exhausting conditioned air through the top. In Morgan Hill’s older single-story homes, we measure this with the blower door and trace it with the thermal camera.
- Your attic insulation looks uneven or disturbed. If you can see joist tops, if there are valleys and peaks in the blown-in material, or if you’ve found rodent droppings, your insulation isn’t doing its job. Our inspection measures what’s there, identifies what’s missing, and documents it with photos you can reference.
- You’re considering solar, a heat pump, or HVAC replacement. Any efficiency upgrade built on top of a leaky envelope wastes money. We regularly audit homes in Saratoga and Los Gatos where homeowners spent $20,000 on a new heat pump, then learned they were still losing 35% of its output to duct leaks. Audit first. Upgrade second.
Our Home Energy Audit Process - Step by Step

- 1
Schedule and confirm. Call (669) 280-8103 and you’ll reach a live person, not a voicemail loop. We confirm your address in Morgan Hill, ask about your primary concerns - high bills, comfort issues, upcoming renovations - and schedule a 2-4 hour window. Under Haven Standard: Arrive on schedule, you get a named technician and a text when they are on the way.
- 2
Written price before any work starts. Before we unload equipment, you receive a flat price for the audit package you choose - basic inspection, standard diagnostic with blower door and thermal imaging, or comprehensive with duct leakage testing. Haven Standard Clause 1: no work starts without a written scope, a written price, and a written warranty. This is not an estimate. It’s the price.
- 3
On-site diagnostic testing. Our technician runs the full test sequence - blower door, thermal scan, insulation measurement, and duct pressurization if included. In Morgan Hill, we typically find the biggest leaks at top plates, recessed lights, and attic hatches. The technician explains findings as they appear, and you can follow the thermal camera in real time.
- 4
Documented Photo Record and blower-door numbers. Every image, every reading, every measurement is saved to your record. You get the before-and-after blower-door CFM50 if we’re doing follow-up work, or the baseline number if you’re evaluating options. This documentation belongs to you. It’s not held hostage for a follow-up sale.
- 5
Written report and next steps. Within 48 hours, you receive a report with prioritized recommendations, estimated performance impact, and flat pricing for any work we propose. No urgency tactics, no “limited-time” discounts. Take the report to another contractor for a Free Second Opinion - we encourage it.
How Much Does Home Energy Audit Cost in Morgan Hill?
A basic visual insulation inspection in Morgan Hill runs $350-$450, typically for newer homes or pre-purchase evaluations where no diagnostic testing is needed. The standard Morgan Hill Home Energy Audit with blower-door test and full thermal imaging runs $550-$750, and that’s what most Morgan Hill homeowners choose - it covers the attic, living space, and accessible crawl space with documented CFM50 and infrared images. A comprehensive audit adding duct leakage testing runs $750-$850, recommended for homes with forced-air systems older than 15 years or any home with comfort complaints in specific rooms.
Several factors move the price within those ranges. Homes over 3,500 square feet take longer to pressurize and scan, adding $100-$150. Split-level or multi-zone HVAC systems require additional duct testing points. Accessibility matters too - we can’t test what we can’t reach, and homes with sealed attic hatches or finished basement ceilings may need minor access work quoted separately. Travel to outlying areas like Ben Lomond or Scotts Valley can add a trip fee, though Morgan Hill proper and nearby Campbell, Milpitas, and Santa Clara are in our standard service zone, and we also offer our Home Energy Audit in Campbell.
To avoid overpaying, get the scope in writing before anyone starts. Some Morgan Hill competitors quote a low “audit” price that’s just a visual walkthrough, then charge separately for the blower door, then again for the thermal camera. Our written price includes everything listed - no incremental add-ons. Every audit also includes our Free Second Opinion on any written estimate you bring us, and the Documented Photo Record is included, not available on request. Call (669) 280-8103 for exact pricing on your home - estimates are free, and the price we write is the price you pay.

Frequently Asked Questions - Home Energy Audit in Morgan Hill

A home energy audit is a diagnostic evaluation of how much conditioned air your house loses and where that loss occurs. We use a blower-door test to measure total leakage, thermal imaging to locate specific problem spots, and visual inspection of insulation and ductwork to build a complete picture of your envelope’s performance. In Morgan Hill, most audits reveal 20-40% more leakage than the homeowner expected, with the biggest losses typically in the attic and duct system. If you’re nearby, see Home Energy Audit - Los Gatos for our neighboring service area. You’ll receive a written report with prioritized fixes and flat pricing for any work.
A standard audit with blower door and thermal imaging takes 2-3 hours in a typical 2,000-square-foot Morgan Hill home, and 3-4 hours for larger homes or those with multiple HVAC zones.
