AC Tune-Up: What's Included and Why It Matters Our 21-Point Checklist, Point by Point
An AC tune-up is preventive service on a system that still works. Here is every one of the 21 points our technicians check, what each one catches, and how to decide how often your air conditioner needs it.

The Basics
What an AC Tune-Up Does (and Doesn't) Do
A tune-up is a scheduled visit to clean, measure and adjust an air conditioner before something goes wrong. The goal is to catch worn parts early, restore lost efficiency and keep the drain system clear, which is a constant battle in a humid climate.
It is not a repair visit. If your system is already blowing warm air, leaking or refusing to start, you need an AC diagnostic to find the fault. A tune-up assumes the system runs and looks for the things that would stop it next month.
Every tune-up ends with a written report. If the technician finds a part that is failing, you get a flat-rate quote and decide whether to fix it now, later or not at all. Nothing extra happens without your approval.
Air Conditioner Tune-Up Checklist: All 21 Points
This is what's included in an AC tune-up from Reliance Air Services. Heat pump owners get the reversing valve check as well; everything else applies to any central system.
| # | Checkpoint | What it catches |
|---|---|---|
| 1 | Refrigerant pressures (suction and discharge) | Undercharge, overcharge or signs of a slow leak |
| 2 | Start and run capacitor microfarad test | Weak capacitors before they strand the compressor |
| 3 | Contactor inspection | Pitted or burned contacts that cause hard starts |
| 4 | Condenser coil inspection and rinse | Dirt, grass and salt film that trap heat |
| 5 | Evaporator coil visual check | Dust buildup, corrosion or early icing |
| 6 | Blower motor amp draw | A motor working harder than it should |
| 7 | Drain line flush and pan clear | Algae and sludge that cause overflows |
| 8 | Thermostat calibration and settings | Wrong readings and short-cycling programs |
| 9 | Air filter inspection | Restricted airflow (replacement filter extra) |
| 10 | Electrical connections and wiring | Loose, burned or corroded terminals |
| 11 | Compressor amp draw | A compressor straining under load |
| 12 | Reversing valve operation (heat pumps) | Valves sticking between heating and cooling |
| 13 | Condenser fan blade and balance | Wobble, cracks and noisy bearings |
| 14 | Refrigerant line insulation | Cracked or missing insulation that sweats |
| 15 | Disconnect fuses and breaker | Undersized or failing protection |
| 16 | Supply and return temperature split | Low cooling output from charge or airflow issues |
| 17 | Visible duct connections and seals | Disconnected or leaking joints near the unit |
| 18 | Voltage and amperage at the unit panel | Low voltage that shortens motor life |
| 19 | Float or safety switch test | A switch that would fail to stop an overflow |
| 20 | Overall efficiency and remaining-life estimate | Systems approaching replacement |
| 21 | Written performance report | A record for warranty and resale files |
Local Conditions
Why Annual AC Service Matters More on the Gulf Coast
Air conditioners along Florida's Gulf Coast run for most of the year, not just a few summer months. That long season means more hours on capacitors, contactors and fan motors, and more time for a drain line to collect algae.
Homes near the water face salt air that corrodes condenser coils and electrical terminals faster than inland equipment. Afternoon thunderstorms bring power flickers and surges that stress the same electrical parts a tune-up tests. A yearly visit is the practical minimum here, and coastal homes often benefit from two.
Keeping up with annual AC service also helps your energy bill. A dirty coil or low charge makes the system run longer for the same comfort. If your bills have crept up, read our guide to high electric bills caused by the AC.
What to Expect
How Your AC Tune-Up Visit Goes
Schedule a time
Call (941) 417-4848 or request a visit online. Spring is ideal, before the heaviest cooling months, but any time of year works.
Technician arrives
A uniformed, background-checked technician arrives in a branded Reliance truck and asks about any changes you have noticed.
Work through the checklist
Outdoor unit first, then the air handler, drain and thermostat. Plan on roughly an hour to an hour and a half for a single system.
Review the report
You get written results and, if anything needs attention, a flat-rate quote to approve or decline.

Common Questions
AC Tune-Up — FAQs
How often should I get an AC tune-up in Florida?
At least once a year, ideally in spring before peak cooling season. Because systems here run most of the year, many homeowners schedule two visits: one before summer and one in fall. Homes on barrier islands or close to the Gulf see more salt corrosion and benefit most from the second visit. Comfort and Comfort+ Air Club plans include two tune-ups.
How long does an AC tune-up take?
Plan on about 60 to 90 minutes for a single system in normal condition. A heavily clogged drain line, a very dirty coil or a second air handler adds time. Your technician will give you a realistic estimate after a quick look, and you do not need to stay in the room while the work is done.
Will skipping maintenance affect my manufacturer warranty?
It can. Many equipment manufacturers expect regular professional maintenance, and a parts claim may be harder to support without records. Each Reliance tune-up ends with a written report you can file with your warranty paperwork. Check the terms in your own warranty document, since requirements vary by brand and model.
Do I need to change my filter before the tune-up?
No. The technician inspects the filter as part of the visit and can replace it if you would like, at the cost of the filter. If you change filters yourself, keep doing so on the schedule your filter type calls for, which is often monthly for basic one-inch filters during heavy cooling months.
Is a tune-up worth it on a newer system?
Yes. New systems still collect dirt on the coils, grow algae in the drain line and lose connections to vibration. Early visits also document that the equipment is maintained, which helps with warranty claims, and they set a baseline for pressures and temperatures that makes future problems easier to spot.
