Levels of service – fees based on time spent on Site Visits and designing Scopes of Work.

  • Cost Estimate for Homeowners Buyers/Sellers – starting as low as $190
  • Holistic Approach – as low as $750
  • Custom Performance Diagnostics – Depends on number of site visits and amount of design work. Call for an initial free consult

Site Visits

  • Design with or without baseline performance testing – both envelope and/or combustion safety tests
  • Final Modifications to Scope of Work
  • Contractor bid analysis
  • Series Air Leakage performance testing
  • Post Improvement performance testing – both final envelope and combustion safety tests

Performance Tests – in order of importance to confirm success!

Envelope air leakage

  1. Series Air Leakage at Ceilings – record air pressure differences that show air leaks between conditioned and unconditioned zones of a house’s envelope. Computerized data is collected. Crawling through unconditioned space provided when pressure standards are not met.  Corrective air sealing direction given during this crawl through.
  2. HVAC Duct Air Leakage – record air pressure differences that show air leakage to unconditioned attics or crawl spaces. Data collected used to determine whether the air leakage in the ductwork meets standards. We direct duct air sealing work should standards not get met.
  3. Recessed Light Air Leakage – record air pressure differences that show air leakage to unconditioned spaces. Data collected to verify air leakage standards are met.
  4. Blower Door – record total envelope air leakage (cfm50) prior to any work and during a post improvement site visit. We use the data collected to determine the minimum required fresh air exchange rate.
  5. Indoor Air Quality – design a proper air exchange rate based on the leakiness of the envelope, total amount of air, and the number of people living in the house.
  6. Infrared Camera – observe heat loss either at voids of insulation or possibly air leakage when used with any blower door test. Data used to direct corrective air sealing and insulation crews work.
  7. Smoke Pencil – squirt smoke to show air leaks. Used while directing air sealing crew’s efforts.
  8. Window Air Leakage – record air pressures differences that show air leakage/flow through sashes. Data collected to verifies whether air leakage falls within NFRC standards.

Air Exchange and Combustion Safety Performance Tests in order of importance

  1. Worst Case Depressurization – record impact of negative air pressures at natural draft flues. Data used to verify devices are safely operating.
  2. Exhaust Fan Flow – record exhaust fan flows. Data collected used to determine the minimum required continuous ventilation rate to maintain fresh air and control the moisture build-up.
  3. Multi-zonal Air Pressure – record air pressures across interior doors of the house while the furnace (or air handler) circulates air through the ductwork of a house. Data collected used to determine how easy it is to close an interior door and cause a backdrafting condition at a natural draft water heater, furnace, boiler and/or fireplace.
  4. Relative Humidity – record RH at a specific location at some time and date. Data collect to note a specific amount with reference to a specific condition.
