Common IAQ system problems

Signs your indoor air system needs service

These symptom-focused sections help homeowners identify the issue and support relevant service searches.

Purifier not operating

The unit has no power, no indicator light or does not run with the HVAC system.

Humidifier not adding moisture

Indoor air remains dry even when the humidifier is turned on.

Water leaking

Leaks may appear around humidifier drains, water lines or internal components.

Unusual noises

Buzzing, rattling or fan noise can indicate a motor, bearing or airflow problem.

HRV or ERV not ventilating

Fresh-air exchange feels weak or the unit does not cycle correctly.

Restricted airflow

Dirty media, filters or blocked components may reduce system performance.

Maintenance, repair or replacement?

Choose the right level of service

Many IAQ problems come from overdue cleaning or consumables, while others involve controls, motors or failed components.

Maintenance may be enough when:

  • Filters, pads or cores are dirty
  • The system is overdue for cleaning
  • Drain lines or ports are partially blocked
  • Performance improves after routine service

Repair or replacement may be needed when:

  • Controls or motors have failed
  • Water leaks continue after maintenance
  • The system is damaged or incompatible
  • Replacement parts are unavailable or uneconomical
Preventive care

Regular cleaning and replacement parts help IAQ systems perform properly.

Use this section for verified maintenance intervals only. Filters, humidifier pads and HRV/ERV cores may require different service schedules depending on the equipment and home.

Air conditioning repair FAQs

Helpful answers before scheduling

Possible causes include a closed water valve, clogged pad, failed solenoid, drain blockage, humidistat issue or lack of furnace airflow.

Possible causes include dirty filters, debris, an unbalanced fan, motor wear or loose panels. The unit should be inspected before continued operation.

Service frequency depends on the equipment, usage and manufacturer instructions. Filters and humidifier pads often require more frequent attention than motors or controls.

A heavily restricted filter can reduce airflow and increase strain on compatible equipment. Replace or clean filters according to the approved schedule.

Cost depends on the equipment, diagnosis and required parts. Publish a diagnostic fee only after the client confirms the exact amount and terms.
