We typically recommend seasonal HVAC maintenance, which for most homes means two maintenance visits per year — one for heating season and one for cooling season. The right schedule can vary based on system age, usage, and indoor air needs, and we can recommend a plan after we see your equipment. Maintenance can help prevent unexpected failures during extreme weather.
