Preventive A/C care
A proper visit helps the system run the way it should, catches developing problems, and gives you a clear picture of its condition before peak heat does the testing for you.
Book the right visit
A maintenance visit needs a running, working system so operation can be checked before and after cleaning. If you already know the equipment has a problem, choose service or repair—not maintenance.

What happens on arrival: If the system is not operating or has a fault, the visit starts as a service diagnostic so the cause can be found and a repair can be offered. Maintenance can follow after the equipment is running. If the system is otherwise working and only needs routine cleaning or condensate-drain service within the maintenance scope, maintenance may be the right visit.
The Sunset standard
Not every system needs the exact same test on every visit. Measurements are used when they answer a real question, components are cleaned when access and condition allow, and any concern is explained without turning a maintenance into a sales pitch.
What we check
The exact scope depends on system type, accessibility, operating conditions, and the equipment manufacturer, but these are the core areas we work through.
Maintenance is performed on a running system so operation can be confirmed before and after cleaning. It reduces avoidable wear and catches problems earlier, but it does not replace a service diagnostic. Repairs or deep cleaning beyond normal scope are quoted separately before work continues.
Maintenance & replacement reminders
Monthly drain cleaning, filter care, system maintenance, UV lamps, and purifier cells—all together. Build a schedule for your equipment and keep the dates handy.
A small, regular check-in for your home A/C condensate drain.

Good questions
Yes. Choose monthly drain cleaning in the reminder planner, set your first date, and download the recurring calendar reminder. You can also save a plan with Sunset. Automatic email/text delivery is not connected yet; saving does not activate messages. Use only the cleaning method approved for your equipment and call if the drain is blocked, leaking, or the system is not operating.
No. Record the installed model and last replacement date, then use the manufacturer’s interval or choose a one-time check until Sunset can confirm it. Reminders do not measure remaining lamp output, cell life, or equipment condition.

For Gulf Coast conditions, twice per year is a strong schedule for most systems—before the hardest cooling season and again around the heating or shoulder season. Homes with pets, heavy use, construction dust, coastal corrosion, or drainage history may benefit from closer attention.
No. If possible, leave the current filter in place so its condition can tell us something about airflow, dust load, sizing, and replacement frequency. Have a new filter available if you already supply your own.
No. Refrigerant is not consumed like fuel. If testing indicates a charge problem, the cause and repair options should be discussed before adding refrigerant.
No. If the system is not operating, has no cooling, is leaking, frozen, tripping a breaker, or has another known problem, schedule a service call first. The cause must be found and approved repairs completed before a proper maintenance can be finished. If the system is operating and routine dirt or condensate buildup is the only concern, maintenance may be appropriate.
No. Marine systems add seawater flow, strainers, pumps, condensers, vessel power, and confined access. Marine service is scheduled separately based on the equipment and vessel location.
