If you’ve ever scheduled an AC tune-up and thought, “What exactly am I paying for?”—you’re not alone. You see a technician walk around your system, maybe spend some time outside by the unit, maybe poke around the thermostat—and then they leave. Sometimes without much of an explanation. It’s no wonder homeowners feel unsure about whether a tune-up is worth the money.
At Bob Boldt HVAC, we believe in full transparency. Not only should you feel confident about what you’re getting, you should understand how each part of the tune-up helps extend the life of your system, reduce your utility bills, and prevent a future breakdown. That’s why we’re pulling back the curtain and walking you through exactly what happens during one of our $89 AC tune-ups.
Let’s take it step-by-step.
The first thing our technician does is evaluate the overall condition of your air conditioning system. This includes checking the age, make, and model, looking for any signs of obvious wear and tear, and confirming that the system matches the home’s cooling needs. We want to understand what we’re working with before we dive into specifics.
A good tune-up isn’t just about checking boxes. It’s about diagnosing how your system is aging, and what can be done to keep it working longer. That insight only comes from experience—and our techs have decades of it.
Dirt is one of the biggest enemies of an efficient AC unit. It builds up on the coils, clogs the filters, and slows down airflow. That’s why one of the first physical actions we take is to clean your condenser coil—the part of your outdoor unit responsible for releasing heat. When this coil gets covered in grime, your system works harder, cools less efficiently, and wears out faster.
We also clear out the condensate drain, which can get clogged with debris and cause water to back up into your home. Left unchecked, that’s a leak (or a mold problem) waiting to happen.
Next, we move on to electrical checks. That means inspecting and tightening connections, testing capacitors, measuring voltage, and ensuring the system starts up correctly. We check the blower motor, fan blades, and compressor—all key parts that keep your system running smoothly. If anything looks weak, worn, or unstable, we catch it early before it turns into an emergency call.
We also test refrigerant levels. Too much or too little refrigerant can reduce performance and increase wear. If your system is low, that may mean there’s a leak somewhere—and you’d want to know that now, not when the unit gives out in July.
Many people don’t realize that their thermostat is a powerful diagnostic tool. If your system is short-cycling, running inconsistently, or overshooting the temperature, we’ll find out through careful calibration. A lot of “mystery” cooling issues can be traced back to a simple thermostat miscommunication. We test the settings, recalibrate if needed, and ensure your thermostat is communicating clearly with your system.
We also test airflow—because even if everything else is perfect, poor airflow can mean your home still feels uncomfortable. That could be due to duct issues, blockages, or a blower fan that’s losing strength. A good technician doesn’t just assume air is moving—they measure it.
Once everything has been cleaned, tested, and tuned, we provide a full report of what we found. You’ll know the condition of your system, what we adjusted, and if anything might need attention in the near future. There’s no upselling, no pressure, and no technical jargon designed to confuse you. Just straight talk from a technician who wants to keep your AC running right—not replace it unless absolutely necessary.
At Bob Boldt HVAC, our goal is to keep your system in the best shape possible—and to help you avoid expensive surprises. That’s why our $89 tune-up includes all of this. We don’t believe in shortcuts. We believe in service.
It’s the easiest decision you’ll make all season. For just $89, you get peace of mind, a cleaner, stronger system, and a cooler home. No pressure, no games—just honest work from people who care about your comfort.
