HVAC failures often become emergencies during the first heat wave or cold snap. You may not control the equipment, but you can test it early and report warning signs before weather becomes dangerous.
- Test the system before peak season Run the heat before the first very cold week and the air conditioner before the hottest part of summer. Report unusual noises, weak airflow, short cycling, burning odors, or failure to reach a normal setting.
- Replace only tenant-responsible filters If the lease makes you responsible for a simple HVAC filter, use the correct size and replacement schedule. Do not open equipment panels or service refrigerant, gas, or electrical components.
- Keep vents and returns clear Avoid blocking supply vents or return grilles with furniture or storage. Note any vents that never produce airflow.
- Report water around HVAC equipment Condensate leaks can damage floors and create mold. Photograph and report leaking air handlers, ceiling drips, or clogged drain symptoms.
- Check smoke and carbon-monoxide alarms If the home has fuel-burning equipment, carbon monoxide is a separate safety concern. Test alarms as allowed by the manufacturer and report missing or nonworking alarms.
- Make a heat or cold backup plan Know where you can go if the unit becomes dangerously hot or cold. 211 and local emergency management agencies can help locate cooling or warming resources in many communities.
Where to Get Help
Important: Local laws differ on required indoor temperatures and whether air conditioning is legally required. Heating is more commonly regulated, but exact standards vary.
