An AC tune up is a scheduled maintenance visit in which a trained technician inspects, cleans, and tests every major component of your cooling system to confirm it is operating safely and efficiently. For Metro Atlanta homeowners, it is one of the most straightforward ways to catch small problems before they turn into expensive repairs in the middle of a Georgia summer.
During a tune up, a technician will clean the evaporator and condenser coils, verify the refrigerant charge, test electrical components and capacitors, clear the condensate drain line, calibrate the thermostat, and check airflow throughout the system. The visit ends with a written report of what was found. That report gives you a clear picture of where your system stands, not a sales pitch.
Georgia summers are not forgiving. Temperatures climb fast, humidity makes everything worse, and a cooling system that has gone a year or more without a look is one hot afternoon away from leaving your family uncomfortable. A tune up is not a luxury. It is basic upkeep, the same way you change the oil in your car before it starts knocking.
All Purpose Heating and Air Conditioning has been doing this work in Atlanta and the surrounding area for more than 35 years. We are locally owned, licensed, and insured, and we treat your home the way we would want ours treated. If you are not sure where your system stands, that is exactly the right time to call.
Some signs are obvious. Some are easy to ignore until they are not.
The clearest trigger is the calendar. If your system has not been serviced in more than a year, it is overdue, full stop. Cooling equipment works hard in Georgia, and a year of continuous use without a check means coils are dirtier, the condensate line may be partially blocked, and you have no idea whether your refrigerant charge is still where it should be.
Watch your energy bills. If your cooling costs have crept up over the past two or three billing cycles and your habits have not changed, your system is working harder than it should to move the same amount of air. A dirty evaporator coil or a low refrigerant charge will do exactly that. The unit runs longer, pulls more power, and still does not quite get the house to the set temperature.
Listen to the system when it kicks on. A healthy unit starts up and runs with a steady hum. Rattling, clicking after startup, or short cycling (where the unit runs for a few minutes and then shuts off before the house cools) all point to something worth investigating. Left alone, a failing capacitor can burn out the compressor. That is the difference between a tune up visit and a major repair bill.
New homeowners face a specific challenge. You may not know when the previous owner last serviced the system, or whether they ever did. A tune up gives you a baseline. You will know exactly what you have before the first real heat wave hits.
A tune up with All Purpose Heating and Air Conditioning follows a consistent sequence. Nothing gets skipped because we are running behind. Here is how the visit actually goes.
Coil cleaning. We start with the evaporator and condenser coils. Dirty coils are one of the most common reasons a system loses efficiency. A clean coil transfers heat the way it is supposed to. A coated one makes the compressor work overtime.
Refrigerant check. We verify the refrigerant charge against the manufacturer’s specification. A system that is low on refrigerant cannot cool your home properly, and it will keep struggling until someone addresses it.
Electrical and capacitor testing. We test the capacitors, contactors, and all electrical connections. Capacitors fail without much warning, and a bad one will take the motor down with it if it is not caught first.
Condensate line clearing. The condensate drain line pulls humidity out of your home. A clogged line backs up into the drain pan and eventually onto your ceiling or floor. We flush it clear.
Thermostat calibration. If your thermostat is reading the temperature inaccurately, the system will short cycle or run too long. We verify it is calibrated correctly.
Airflow check. We check static pressure and airflow to confirm that conditioned air is actually reaching the rooms it is supposed to reach.
Written report. Before we leave, we hand you a written summary of everything we checked, what we found, and what, if anything, needs attention. You keep that report.
All Purpose Heating and Air Conditioning serves homeowners across Metro Atlanta and the surrounding Georgia communities, including Alpharetta, Conyers, Peachtree City, Newnan, and McDonough. Wherever you are in our service area, the same team and the same process show up at your door.
What affects how long a tune up takes and what it costs? A few things, and none of them are hidden.
System type matters. A standard central air system is a straightforward visit. A home with a heat pump, a zoned system, or multiple air handlers takes longer because there are more components to inspect and test. The number of systems in the home plays into it as well. A single-unit home and a home with three separate systems are simply different scopes of work.
What we find during the visit can also affect the timeline. If the tune up turns up a refrigerant leak, a failing capacitor, or a condensate line that is fully blocked, addressing those issues on the same visit is almost always the smarter call. If a repair turns out to be beyond the scope of a tune up, our technicians will explain what they found and what the next step looks like. You can read more about what that looks like on our AC repair service page. And if the visit surfaces concerns about your heating equipment heading into fall, our team handles that too. Our furnace repair service covers the heating side of the same system.
The most accurate number for your home is always going to come from an actual look at your equipment. Request your estimate and we will get someone out to you.
