Tools

• check_ventilation_unit ~500 tokens
  Checks a quoted HRV or ERV against bedroom airflow needs using exact-model HVI-certified data. Returns a screening verdict, reasons, assumptions and questions for the installer. Ambiguous model names return candidates for clarification rather than a guessed model. Does not provide a permit-ready des
• explain_co2_reading ~334 tokens
  Explains a bedroom CO₂ reading against the precautionary 800 ppm average-while-asleep goal: band, distance from the goal, whether the measurement is comparable, signs of a monitor reading low, and free fixes with trade-offs. The goal is not a health limit. Door-open nights appear only as one-night t
• find_installers ~264 tokens
  Lists HRV and ERV installer companies for a US ZIP code in HouseExhale’s neutral order, with its ordering rule and coverage limits. Returns member companies where the installer program is open, otherwise researched companies from public pages covering the Colorado Front Range and New England. Contai
• find_rebates ~197 tokens
  What HouseExhale’s research found for a state (by ZIP code or state): utility and state programs that pay toward an HRV or ERV by name, other ventilation rebates, air sealing and insulation help, the state’s federal home energy rebates, state tax credits, and the status of the federal tax credits. E
• units_to_ask_about ~365 tokens
  Lists up to three reviewed HRV/ERV families whose HVI-certified airflow covers what the household’s bedrooms need at night, with margin: units to ask installers about, never a single pick or a recommendation, and never paid placement. Also returns the night airflow target and how it was worked out.
