Most AC tune-up ads promise “29-point inspections” or “precision tune-ups,” but they rarely explain what actually happens once the technician pulls into your driveway. If you’ve ever wondered what you’re really paying for, you’re not alone.
As a licensed plumbing and HVAC company serving Memphis, we want you to feel confident about every visit. At Smith's Plumbing, Heating & Air, our 5-star-rated team focuses on clear communication, upfront pricing, and educating homeowners, so an AC tune-up in Memphis feels transparent instead of mysterious.
Here’s what you can expect from a professional visit, step by step, and how our Memphis climate shapes the way we maintain your system.
Before We Arrive: How to Prepare for Your Tune-Up
A smooth visit starts before we ever open the toolbox. A few quick steps on your end help us work efficiently and respect your time.
First, it helps to know where key components are located. Make sure you can point us to the indoor air handler, the outdoor condenser unit, and your thermostat. If the outdoor unit is surrounded by lawn furniture, toys, or yard tools, try to clear two to three feet of space around it so we can safely access all sides.
Next, gather any basic system details you know: the brand, approximate age, and whether it’s had any recent repairs or odd symptoms, such as hot spots in certain rooms, short cycling, or unusual noises. That information helps us prioritize what to look at first.
You don’t have to worry about picking up parts in advance. Our technicians arrive in fully stocked service vans, so we typically have what we need on hand for common air conditioning maintenance tasks like replacing worn contactors, adding a drain line treatment, or swapping a bad capacitor.
What We Check on the Outdoor Unit
The outdoor condenser does a lot of heavy lifting in a Memphis summer. Our humid subtropical climate, with long cooling seasons and plenty of pollen, means this unit deserves close attention during an AC tune-up.
Condenser Coil Cleaning
We start with a visual inspection of the condenser coil, the finned “radiator” that releases heat pulled from inside your home. In Memphis, spring pollen, lawn clippings, and dust can quickly clog this coil. When that happens, air can’t move through it freely, refrigerant doesn’t cool properly, and efficiency drops.
During air conditioning maintenance, we remove surface debris, carefully straighten any crushed fins where possible, and clean the coil to support proper airflow. This helps the system run cooler, use less energy, and reduces strain on the compressor.
Capacitor & Contactor Inspection
Next, we check the electrical heart of the outdoor unit: the capacitors and contactor. The capacitor stores energy to help the compressor and fan motor start smoothly, while the contactor is a heavy-duty switch that turns the unit on and off thousands of times over a season.
Because Memphis systems often run from April into early fall, these parts see a lot of cycles. We test the capacitor’s rating against manufacturer specifications and inspect the contactor for pitting, burning, or sticking. Catching a weakening capacitor or worn contactor during a tune-up is far better than discovering it during a July heat wave when the unit won’t start.
Refrigerant Level Check
We connect gauges to measure system pressures and compare them with the manufacturer’s recommended range for your specific model. This refrigerant level check helps us determine whether the system’s operating efficiently.
In a humid climate like Memphis, long run times can disguise a refrigerant problem for a while. The home might still feel cool enough, but the system could be running longer than necessary, driving up bills and stressing the compressor. A tune-up doesn’t include leak repair, but it does flag abnormal pressures so we can explain what we found and, if needed, discuss a separate repair to locate and fix the leak before adding refrigerant.
What We Check on the Indoor Unit
The indoor side of your air conditioner is where heat and moisture are pulled from the air. Because Memphis AC systems run heavily through our long, sticky summers, the evaporator coil, blower, and condensate drain line all face extended stress.
Evaporator Coil Inspection
The evaporator coil sits inside or just above your furnace or air handler. Warm indoor air passes over this cold coil, which cools the air and removes humidity. We inspect the coil for dirt buildup, corrosion, and any signs of icing.
In high humidity, even a small airflow restriction can cause the coil surface to drop below the dew point, allowing ice to form. Ice insulates the coil, reduces cooling, and can eventually block airflow altogether. If we see dirt or early signs of icing, we can explain whether cleaning can be handled within routine maintenance or requires a separate deep cleaning.
Condensate Drain Line & Pan
Every bit of moisture your system removes has to go somewhere. It drips into a drain pan and then out through the condensate drain line. In Memphis, where relative humidity often sits in the upper 60s to high 70s during summer, that line carries a lot of water.
During an AC tune-up, we inspect the pan and drain line for clogs, algae, and signs of past overflow. Clearing the line and, when appropriate, applying a treatment tablet or solution helps reduce one of the most common warm-weather headaches: water spilling from an air handler and damaging ceilings, walls, or floors.
Blower Motor & Blower Wheel
The blower is the fan that pushes conditioned air through your ducts. We measure the blower motor’s amperage draw to see how hard it’s working compared with its rated load. A motor pulling more current than it should is often dealing with restrictions like a dirty filter, clogged coil, or dirty blower wheel.
We also inspect the blower wheel itself. Dust and pet hair that stick to the blades change their shape and reduce airflow. When needed, we’ll recommend cleaning the wheel as a separate service, since it may involve more disassembly than a standard tune-up.
Electrical, Controls & Safety Checks
Once both the indoor and outdoor components have been checked, we turn to the controls and safety features that help keep the system operating reliably.
Electrical Connections & Components
Vibration and thermal expansion can loosen electrical connections over time. During air conditioning maintenance, we inspect and tighten accessible electrical connections, looking for signs of heat discoloration, corrosion, or damaged insulation.
Loose connections create resistance, which generates heat and can shorten the life of motors, boards, and other components. This is the kind of issue a quick visual glance won’t catch.
Thermostat Calibration & Settings
The thermostat is the control center for your AC. We verify that it’s mounted securely, check that the temperature reading matches actual room conditions, and confirm proper operation through a full cooling cycle.
A miscalibrated thermostat can cause your system to short cycle, turning on and off too frequently, or to overrun and overshoot the set temperature. When appropriate, we’ll also discuss your thermostat’s features, such as programming or Wi-Fi options, to help you use it to its full potential.
Safety Controls & Shutoffs
Modern systems include safety controls designed to shut the equipment down before damage occurs. During an AC tune-up in Memphis, we test key safeties such as high-pressure switches, overflow float switches on the drain pan, and other applicable controls specific to your system.
In our climate, where systems often run near capacity through the hottest stretches of summer, confirming those safeties work correctly gives you an important layer of protection against water damage and major mechanical failures.
After the Visit: Reviewing Findings & Next Steps
When we finish the inspection and tune-up steps, we don’t just pack up and leave. One of the most important parts of the visit is the conversation at the end.
We walk you through what we checked, what we adjusted or cleaned as part of the tune-up, and anything we found that falls outside normal maintenance. For example, clearing a minor drain line restriction or tightening a loose wire is typically included. Finding a leaking evaporator coil or a compressor drawing dangerously high amperage isn’t.
Any issue that requires additional labor or parts beyond a standard tune-up is presented as a separate repair. Because Smith's Plumbing, Heating & Air follows an upfront pricing approach, we explain the problem, discuss options, and provide a clear quote before any repair work begins. You decide whether to proceed right away, schedule for later, or hold off, with no surprise charges.
Most manufacturer warranty compliance language calls for documented annual maintenance by a qualified HVAC professional. Your post-visit summary from our licensed team can serve as proof that your system has been maintained, which may be important if a major component fails while under warranty.
When to Schedule a Memphis AC Tune-Up
Timing matters. A tune-up is most effective before your air conditioner is working its hardest.
For the Memphis area, spring is the ideal window. As temperatures climb toward the upper 80s and humidity levels rise from June through August, systems run near full capacity for long stretches. Finding and addressing problems before that stretch starts gives you far more breathing room.
If your system is more than ten years old, or if it ran almost nonstop through last summer, consider scheduling earlier in the season instead of waiting until the first heat wave. Schedules fill quickly once the first round of “no cool” calls start, and tune-ups are easiest to complete before emergency demand spikes.
Homeowners who skipped maintenance last year or noticed rising utility bills without changing their thermostat settings should treat this season’s visit as both preventive care and a baseline check. We can compare how your system is running now with future visits, which helps identify trends before they turn into bigger problems.
Making Your Memphis Tune-Up Count
An AC tune-up is most valuable when you understand what was done and why. Knowing that your technician inspected the evaporator coil for icing, cleared the condensate drain line, checked blower motor amperage, cleaned the condenser coil, tested capacitors and contactors, and verified thermostat operation turns the visit into a clear investment, not a mystery charge.
