Package Unit Maintenance
A complete System Performance Evaluation and Safety Inspection for your all-in-one heating and cooling system.
A Complete System Performance Evaluation
Your package unit does two jobs from one cabinet — it heats and it cools — whether it’s a gas/electric “gas pack” or a heat-pump package mounted on your roof or at ground level. Most maintenance visits in our industry confirm one thing: that the unit still turns on. At Reliable Comfort Services, we go much further. Our maintenance is a full evaluation of how your package system is actually performing in both heating and cooling modes, and whether any component is beginning to show wear or pose a safety concern — long before it leaves you without comfort.
That distinction matters. A unit that runs is not the same as a unit that is operating correctly and safely. Our team brings 50+ years of combined experience caring for package HVAC systems across Middle Tennessee, and our System Performance Evaluation and Safety Inspection is built to evaluate condition, not just confirm operation. We measure, we test, and we tell you exactly where your equipment stands.
Why Choose Us
The typical maintenance visit verifies that a package unit powers on and moves air, then leaves. That tells you almost nothing about the condition of the equipment. Our System Performance Evaluation and Safety Inspection measures how your system performs in both heating and cooling, checks every safety device, and identifies components that are still working but starting to decline.
Our team brings 50+ years of combined experience serving Middle Tennessee. When we evaluate your package unit, you’re working with neighbors who stand behind their reputation. We arrive on time, document every reading, classify the condition of your system honestly, and stay available for follow-up questions.
A package unit shares a single cabinet, control board, and curb or pad connection between its heating and cooling sections. Evaluating it well means understanding how those sections interact. Our EPA 608-certified technicians test both sides of the system — combustion and heat exchanger on gas packs, the reversing valve and refrigerant circuit on heat-pump packages.
A blower motor or compressor that still runs but draws higher-than-normal amperage is already beginning to fail, even though nothing has stopped yet. A capacitor measured below its rated capacitance is on its way out. We find those conditions while the system is still working, which is exactly when you have time to plan rather than react.
Many package-unit warranties require documented annual professional maintenance to stay valid. Skipping it can void coverage on both the heating and cooling sections. Our inspection creates the service record manufacturers ask for.
Reliable Comfort Services is a member of the TVA EnergyRight Quality Contractor Network, and annual maintenance qualifies for a $50 TVA EnergyRight rebate per unit, per year. It’s one more way regular, professional care pays you back.
Schedule Your Package Unit Performance Evaluation
Is it time for your annual evaluation? Spring is ideal for verifying cooling performance, and fall is ideal for confirming heating and combustion safety before the cold. We’ll evaluate both sides of your package unit, measure how it’s performing, and review every finding with you in plain language.

Our Process
Because a package unit lives outdoors — exposed on a rooftop or at ground level — and many models burn gas, safety comes first. On gas packs, we inspect the gas connections, evaluate combustion, and check the heat exchanger for cracks or corrosion that could allow carbon monoxide to mix with your heated air. We verify electrical safety throughout the cabinet, confirm the condensate drain and overflow are clear and draining properly, and inspect the curb or pad mounting and cabinet integrity for rust, weather damage, and seal failures where water can get in.
A package unit can only heat or cool as well as it can move air, and poor airflow quietly damages equipment over time. We measure static pressure to see how hard the blower is working, evaluate blower performance, and check the filter and any airflow restrictions. We inspect the duct and curb connection for leaks where conditioned air escapes before it reaches your rooms, and we measure temperature rise in heating and temperature split in cooling to confirm the unit is performing to specification.
This is where evaluating condition separates us from a quick visit. We test capacitors for their actual measured capacitance — not just whether they’re present — because a capacitor reading below spec is already failing. We inspect contactors, measure the amperage drawn by the compressor and fan motors, and check the control board, safety devices, wiring, and voltage. A motor that’s still running but pulling higher-than-normal amperage is beginning to fail even though it hasn’t stopped, and catching that early is the core value of this inspection.
With the system running, we verify how the equipment is actually performing. We check refrigerant pressures and measure superheat and subcooling to confirm the charge is correct and the refrigerant circuit is healthy. We evaluate compressor operation and the performance of the condenser and evaporator coils. On gas-pack systems, we also verify combustion performance and confirm the heat exchanger is heating the air safely and efficiently.
When testing is complete, we don’t just tell you “it’s running.” We classify the condition of your package unit using our Red / Yellow / Green standard and sit down with you to review what we found. You’ll see the measurements, understand which components are healthy and which are showing wear, and leave with a clear picture of your system’s condition and any recommendations — with no pressure and no surprises.
Clear Classification
To eliminate guesswork, we classify every major component and the system as a whole into one of three clear categories. It gives you an honest early-warning picture instead of a vague “looks fine.”
Operating normally and within expected parameters. No action needed.
Still operating, but measurements show wear or declining performance. This isn’t an emergency; it’s a chance to plan ahead before the component fails.
Failed, near failure, or a safety concern. We recommend addressing these promptly to restore safe, reliable operation.
The goal is simple: eliminate surprises. By the time something would have left you without heat or cooling, you’ve already heard about it — and had time to decide what to do.

Answering Your Questions
A thorough System Performance Evaluation and Safety Inspection typically takes about 1.5 to 2 hours, and sometimes longer depending on the system. The first visit takes the longest because we establish a complete performance baseline — measuring how your package unit operates so future visits can be compared against it. A quick visit that's over in twenty minutes simply isn't evaluating your equipment's condition.
A basic tune-up usually confirms that the unit turns on and moves air. Our inspection evaluates how your package unit is actually performing in both heating and cooling, tests every safety device, and identifies components that are beginning to wear out before they fail. We measure and classify the condition of your equipment rather than just confirming it runs.
We recommend a full evaluation at least once a year. Because a package unit both heats and cools, an annual inspection lets us confirm combustion and heating safety and verify cooling performance on the same visit. Monthly filter changes between visits are also essential, since a restricted filter strains the blower and reduces performance on both sides of the system.
It's how we classify the condition of your equipment so there are no surprises. Green means a component is operating normally. Yellow means it still works but is showing wear, so you can plan ahead. Red means it has failed, is near failure, or is a safety concern we recommend addressing promptly. It gives you early warning before a breakdown.
The cost varies depending on your system, so we'd rather give you an accurate quote than a misleading number — just ask and we'll provide one. Keep in mind that Reliable Comfort Services is a member of the TVA EnergyRight Quality Contractor Network, and annual maintenance qualifies for a $50 TVA EnergyRight rebate per unit, per year, which helps offset the cost.
Because a component can be running and failing at the same time. A capacitor measured below its rated capacitance, or a motor drawing higher-than-normal amperage, is already on its way out even though nothing has stopped yet. Catching that early — while the system still works — is the core value of our inspection and lets you plan a repair instead of facing a breakdown.
Yes. On gas/electric package units, combustion safety is a central part of the inspection. We evaluate the gas connections and combustion, inspect the heat exchanger for cracks and corrosion, and check for carbon-monoxide risk, along with verifying that the unit is heating efficiently. Safety verification is the first step of every visit.
Many manufacturers require documented annual professional maintenance to keep the warranty valid on both the heating and cooling sections. Skipping maintenance can void that coverage. Our inspection creates the documented service record manufacturers require, helping keep your warranty active.
We'll explain exactly what we found, show you the measurements, and classify the issue using our Red / Yellow / Green standard. Some findings need prompt attention, especially safety concerns; others can be planned for if the system is still operating adequately. We never pressure you to repair on the spot — we explain the situation and you decide.
A good evaluation can help an aging system run reliably for several more years, and we'll recommend that whenever it makes sense. But if your unit is well past its expected life and major repairs keep recurring, we'll be honest about it and discuss replacement options and financing through Wells Fargo, TVA Financing, and Synchrony so you can make an informed decision.
We service all major brands, including LG, Carrier, Trane, Ruud, Goodman, and others. Our evaluation procedures apply across brands, though we follow each manufacturer's specific recommendations. For new installations, our primary package and split-system brand is Tempstar. If your system is a different brand, call us — we very likely service it.
Either works for an annual evaluation, but fall has an added benefit for gas packs: it confirms combustion safety and heating readiness before winter. Spring is ideal for verifying cooling performance before summer. The most important thing is having at least one complete inspection each year; if you run your system hard in both seasons, scheduling both is worthwhile.
