Before the season finds the weak part · Emergency calls until 11 PM
HVAC maintenance and AC tune-ups for homes and businesses
An HVAC maintenance visit, or AC tune-up, checks the whole system in one go: the refrigerant charge, the capacitor, the coil, the drain, the airflow and the thermostat. Done in the spring, it catches the weak part before the first 95-degree day. You hear back within the hour when you book, and anything we find is quoted in writing before it's touched.

Cloud 9 AC Services does HVAC maintenance and AC tune-ups for homes and commercial buildings across West Orange County and South Lake: a single tune-up when you want one, or a maintenance plan that puts the visits on a calendar. Each visit checks the parts that fail in a Florida summer and tells you what's wearing before it breaks.
We're based in Winter Garden and work across West Orange County and South Lake. A tune-up is one visit that you book when you think of it. A maintenance plan is the same checklist with the dates already set, and it has its own page.
- Where
- Winter Garden, Ocoee, Oakland, Windermere, Horizon West, Clermont, Minneola, Apopka and the towns between
- For
- Homes, and buildings run by property managers, restaurants, retail, medical offices
- Equipment
- Split systems, heat pumps, rooftop package units, air handlers, thermostats & controls
Before it turns into a repair
Signs your AC is due for a tune-up
None of these signs is an emergency yet, but each one can turn into one in July if nobody looks at the system in April.
-
It hasn't been looked at since last summer.
Have it looked at once a year at least, before the heat arrives. In Central Florida the unit runs most of the year, so a second visit in the fall is worth having.
-
The filter's black in a month.
Either the house is dustier than the filter is rated for, or the ducts are pulling air from somewhere they shouldn't. A tune-up visit will tell you which one it is.
-
Bills creeping up, nothing else changed.
A dirty coil, a low charge or a weak capacitor makes the same cooling cost more every month. Each is a tune-up item when it's caught early.
-
It's noisier than it used to be.
A rattle, a hum on start or a squeal from the blower usually means a part is wearing out. It's cheap to deal with now and expensive when it fails in the middle of July.
-
The drain line has never been cleared.
Algae clogs it, the float switch trips, and the system shuts itself off on the hottest day of the year. Clearing it takes five minutes on a maintenance visit.
-
You've just bought the place.
Nobody can tell you when it was last serviced or what has been replaced. One visit puts the system on file with its age and its condition.
One visit, the whole system
What an AC tune-up includes
This is our tune-up checklist, in the order it happens on the day. A maintenance plan is this same visit with the dates already set.
- Outside: the condenser. We read the refrigerant pressures against the day's temperature and take amp draws on the compressor and the fan motor. We also look at the contactor and the capacitor while the unit runs.
- Inside: the air handler. We clean the indoor coil with a self-rinsing coil cleaner, check the blower, and look over the cabinet and the connections at the air handler.
- The drain. We put pan tablets in the drain pan to keep the line clear and check the pan and the float switch. A blocked drain is the most common reason a Florida system shuts itself off in July.
- The filter. We check the filter every visit. On a commercial system we change it, and at home we change it whenever you leave one out for us.
- The numbers. We write down the pressures and amp draws, so the next visit has something to compare against and a tiring motor shows up early.
- The whole system, running. We run the system through a full cycle and check that it's doing what it should. Anything wearing is quoted in writing before it's touched. A full coil clean or a chemical condenser cleaning is the only extra, and we quote it first.
A commercial tune-up covers every unit on the roof or the wall in one visit, on a schedule the building sets. We check the filters, belts, coils, drains and controls and write each unit's numbers against its tag, so the next visit has a history. Whoever answers for the building gets a written report.
- Access
- We arrange the roof keys and the lift once and keep the details on file for every visit after.
- Hours
- We schedule the visit around your opening hours, so a restaurant gets its tune-up at 9 a.m. instead of during the lunch rush.
- Report
- You get a written report after each visit with what we found, what we did and what to watch. There's a copy for your file and one for the landlord if they ask.
This visit, on a calendar
Maintenance plans for regular tune-ups
A tune-up is this checklist once, when you think to book it. A plan is the same checklist with the dates already set, once or twice a year, with each visit's numbers kept against your equipment.
-
Nothing to remember.
We schedule the visit before the hot season starts, so you never have to remember to book it. You get a date and we show up on it.
-
A history, not a snapshot.
Today's readings become the baseline for the next visit. Reading the two side by side is how a slow leak or a tiring motor shows up a year early.
-
One number when something breaks.
Plan or not, you call the same number. Plan members are scheduled first and get a discount on the repair, and with the unit on file the call starts with what we already know about it.

Due to issues I’ve had with previous AC services I took the advice of other locals in my area and used Cloud 9. They now do my bi-annual maintenance and all my repairs.
Christine G.Google · 2024
Quick and easy to schedule service. Honest and knowledgeable. We signed up for their yearly service plan.

Questions
AC tune-up and maintenance questions
Here's what people ask us about looking after a system, from how often to book a tune-up to whether a plan is worth it.
How often should I schedule routine maintenance?
Once a year at the least, before the summer, so a weak capacitor or a low charge is caught in April instead of on the first 95-degree day. In Central Florida the unit runs most of the year, so a second look in the fall is worth having. A plan puts those visits on the calendar so nobody has to remember; a one-off tune-up is the same checklist, booked when you think of it.
When is the best time of year for an AC tune-up?
Spring, before the first stretch of 90-degree days, so a weak part is found while the weather is still forgiving and the schedule is still open. In Central Florida the unit then runs hard through October, so a second visit in the fall, before a heat pump switches over to heating, is worth having. The worst time is July: the part fails then, the phones are full then, and the house is hottest then.
How often should I change my AC filter?
A standard one-inch filter every month through the summer and every two in the cooler months; a thick media filter in its own cabinet every six to twelve. Pets, a house under renovation or a family with allergies shorten all of those. Hold it up to the light: if you can't see through it, it's done. A loaded filter is the cheapest problem an air conditioner can have and the most common one we find.
Why does my AC shut off and leave water near the air handler?
It usually means the condensate drain line is blocked. A Florida system pulls gallons of water out of the air every day and sends it down a small PVC line. Algae grows in that line, the pan backs up, and the float switch shuts the system off before the ceiling gets wet. If there's a cleanout cap on the line, a cup of vinegar down it every month or so keeps it clear. If the water is already on the floor, turn the system off and call us. The switch has done its job, and the line needs to be flushed before the system goes back on.
What's the difference between a plan and a tune-up?
A tune-up is a single visit that you book when you think of it. A plan puts the visits on a calendar, once or twice a year for a home and on a schedule set for each property for a building. Plan members also get priority when the season fills the phone, and a discount on repairs. The checklist is the same either way, but with a plan nobody has to remember to book it.
