What does an AC tune-up include?
Short Answer: A thorough tune-up checks the whole system: refrigerant level, the capacitor and contactor and electrical connections, the coils, the condensate drain, the blower and filter, and the thermostat. We clean what needs cleaning, tighten what is loose, and flag anything wearing out before it leaves you without cooling.
On a maintenance visit, we go through the system point by point:
- Check the refrigerant charge and inspect for leaks
- Test the capacitor, contactor, and electrical connections, and tighten what is loose
- Clean the condenser and evaporator coils so the system can shed heat
- Clear the condensate drain so it does not back up and overflow
- Check the blower, change or clean the filter, and confirm airflow
- Calibrate the thermostat and verify the full cooling cycle
Most of what kills an AC in a Lowcountry summer is a small thing left unattended, a weak capacitor, a dirty coil, a low charge, and catching it on a tune-up is how we fix it right the first time, instead of meeting you on the worst day of the year.
Coastal Air Plus maintains and tunes up air conditioners across the Charleston Lowcountry and the Grand Strand.
A yearly tune-up in spring catches a weak part before it fails, keeps your system efficient, protects the manufacturer warranty, and helps you avoid a breakdown in July.

How often should I service my AC?
Short Answer: At least once a year, ideally in spring before the cooling season starts. Homes right on the coast benefit from a second visit, because salt air works on the system year-round. A heat pump that also heats in winter is worth checking twice a year.
Once a year is the baseline, and spring is the time, so the system is ready before the first stretch of real heat. If you live on the beach, where salt is constantly at work, or you run a heat pump that heats as well as cools, twice a year makes sense. We will set a schedule that matches your home and your equipment rather than selling you visits you do not need, because treating folks right for the long term is the whole business.

Will AC maintenance keep my manufacturer's warranty valid?
- Short Answer: Usually, yes, and neglecting it can void coverage. Most HVAC manufacturers require proof the system has been properly maintained to honor a warranty claim, and neglect is a common reason claims are denied. We keep a record of every visit, so if you ever need a covered part, you have that proof.
This catches a lot of homeowners off guard: most manufacturer warranties have fine print requiring the system to be properly maintained, so a neglected system can lose its coverage right when an expensive part fails. We document each maintenance visit, which protects that coverage and gives you proof the system was cared for if a claim is ever questioned. It is one of the quieter reasons a maintenance plan pays for itself.
Does coastal salt change what maintenance my AC needs?
- Short Answer: Yes. Near the ocean, salt corrodes coils and electrical parts, so coastal systems need a regular freshwater rinse and closer attention than inland ones. Inland, the bigger issue is pollen and humidity clogging filters and coils. We tailor the visit to where you live.
On
Folly Beach and
Isle of Palms, we rinse the salt off the outdoor unit and watch the coils and contactors closely, because the ocean is hard on equipment. Inland in
Goose Creek or out in the Summerville pines, salt is barely a factor and the focus shifts to pollen-clogged filters and coils. Reading those conditions block by block is not better, just different from a chain that runs the same checklist everywhere.
How much does a new AC cost, and can I finance it?
- Short Answer: A one-time tune-up for a single system typically runs about $99 to $229. Our VIP Maintenance Club bundles scheduled visits with priority service and repair discounts for a membership fee, which is the better value if you plan to keep the system maintained, and most people should.

Why Lowcountry homeowners trust Coastal Air Plus for maintenance
We have kept systems running on this coast since 1947, and maintenance is where that long view shows. We are not looking for a one-time visit; we are looking to keep your system healthy so you call us when it is finally time for a new one and not before. If a tune-up turns up something serious, we are the same crew for the repair or, eventually, the replacement. We maintain systems across Charleston County and the whole Lowcountry, plus the Grand Strand in Horry County.
Creating Lasting Relationships is the idea: keep your system healthy, tell you the truth about its condition, and earn the next call.

AC Maintenance FAQ
When is the best time of year to get my AC tuned up?
Spring, before the first real heat. Getting the system checked in March, April, or May means a weak part is caught and fixed while the weather is mild, instead of failing during the first hot stretch when everyone is calling at once. If you run a heat pump, a fall check before heating season helps too.
Can a tune-up really prevent a summer breakdown?
Most of the time, yes. The majority of peak-season failures we see trace back to something a tune-up would have caught: a weak capacitor, a low refrigerant charge, or a coil so dirty the system overheats. Catching those in spring is far cheaper and less miserable than an emergency call in July.
What happens if I never service my AC?
It works harder, costs more to run, and fails sooner. Dirty coils and a clogged filter choke airflow, parts wear out faster, small problems compound, and you can lose the manufacturer warranty for neglect. Skipping maintenance is the most expensive way to save a little money.
Is maintenance required to keep my manufacturer warranty?
Usually. Most HVAC manufacturers require proof the system has been properly maintained to honor a warranty claim, and neglect is a common reason a claim is denied. We document every visit so you have that proof if a covered part ever fails.
How long does a maintenance visit take?
Most single-system tune-ups take about an hour, longer for a multi-system home or if we find something that needs cleaning or correcting. We will not rush the checklist, because a quick once-over that misses a failing part defeats the purpose.
Can you maintain a system another company installed?
Yes. We tune up and maintain systems of any age and brand, no matter who installed them. We will give you an honest read on the system's condition and what it needs, with no pressure to replace something that has good life left.
