AC Tune-Up service that keeps summer breakdowns off your calendar
A thorough tune-up is more than a quick rinse of the outdoor coil. We clean, test and measure the whole cooling system, record the results, and point out anything that could fail when demand peaks.
- Coils, drains and electrical
- Refrigerant and airflow readings
- Written results each visit
Why an AC tune-up pays off
Cooling systems lose performance gradually. Dust coats the indoor coil, debris packs the outdoor fins, capacitors drift and drain lines collect slime. Each change is small, but together they reduce capacity, raise energy use and increase the chance of a breakdown on the hottest day of the year.
A tune-up reverses much of that decline and identifies parts that are close to failing. It also provides a record of readings from season to season, which helps spot a slow refrigerant leak or a weakening motor long before it becomes an emergency.
We recommend scheduling in spring, before cooling demand rises and before appointment slots fill with repair calls.
Schedule your AC tune-up before the first heat wave arrives.

Each tune-up follows a written checklist so nothing is skipped.
Cleaning
The outdoor condenser coil is cleaned so it can reject heat efficiently. Where accessible, the indoor evaporator coil is inspected and cleaned, and the blower wheel is checked for dust buildup that reduces airflow. We clear debris around the outdoor unit and confirm there is enough clearance for air to move freely.
Electrical testing
Capacitors are measured against their rated values, motor amperage is compared with nameplate data, and terminals are checked for tightness and signs of overheating. The contactor is inspected for pitting. These checks catch the most common causes of sudden summer failures.
Refrigerant and performance readings
Pressures, superheat and subcooling are measured to confirm the refrigerant charge is appropriate. We also record the temperature drop across the indoor coil. If readings suggest a leak, we explain what we found rather than simply adding refrigerant, since a leak needs to be located and repaired.
Drainage, filters and controls
The condensate drain line is flushed, the pan inspected and any float switch or condensate pump tested. The air filter is checked and replaced if you supply one or request one. Finally, the thermostat is tested to make sure it starts and stops the system correctly.
Getting the most from a seasonal cooling inspection
A tune-up is a partnership. The technician handles the measurements and cleaning that require tools and training, and the household handles the small habits that keep the system healthy between visits. These notes cover both sides.
When to schedule
Spring is the most practical time, before the first stretch of hot weather arrives. The system can be tested under real operating conditions, any worn parts can be replaced before they are needed daily, and appointment times are easier to arrange. Many manufacturers publish minimum outdoor temperatures for checking refrigerant charge accurately, which is another reason to schedule once the weather has warmed a little rather than in the middle of winter.
Preparing the home for the visit
Clear a path to the indoor equipment and the outdoor unit, and move stored items away from the furnace or air handler. Note any symptoms you have noticed, such as a room that never cools, a new noise or water near the indoor unit, and share them when the technician arrives. If you know when the filter was last changed, mention that too. Small details help focus the inspection on what matters in your particular home.
Filter habits that make a difference
Filters protect the blower and coil from dust. A common guideline is to check disposable filters monthly and replace them every one to three months, more often in homes with pets, ongoing renovation or heavy pollen. Thicker media filters usually last longer. Choose a filter the system can breathe through, since a very dense filter in a system not designed for it can restrict airflow. If you are unsure which rating suits your equipment, we can check the pressure drop during the tune-up.
Caring for the outdoor unit
Keep grass clippings, leaves, cottonwood fluff and mulch away from the coil fins, and trim shrubs so air can flow freely around the cabinet. Avoid stacking items on top of the unit, since most condensers discharge air upward. Rinsing the coil gently with a garden hose, from the inside out where possible and with the power switched off, can help between visits. Do not use a pressure washer, which can flatten the delicate fins.
Reading what the technician tells you
A good tune-up ends with information, not just a signature. Ask to see the recorded readings, including refrigerant pressures, superheat or subcooling, the temperature drop across the indoor coil and capacitor values. Those numbers become a baseline. When the next inspection shows a capacitor drifting lower or a temperature drop shrinking, you have early warning of a trend, long before it becomes a breakdown.
What a tune-up will not do
An inspection cannot make an undersized system cool a house it was never able to cool, and it cannot repair a leaking duct system hidden in the attic. When the readings suggest that comfort problems come from sizing, ductwork or insulation, we explain that clearly rather than recommending parts the system does not need. Honest limits are part of a useful maintenance visit.
Maintenance and warranties
Manufacturer warranties usually exclude damage caused by neglect, and some warranty terms mention maintenance directly. Keeping the dated work orders from each tune-up gives you a simple record should a warranty question ever arise. Read the terms for your specific equipment, since they vary between brands and product lines.
Signs a tune-up should not wait for spring
Some symptoms justify a visit whatever the calendar says: an outdoor unit that hums without starting, ice on the refrigerant lines, water pooling near the indoor equipment, a burning smell when cooling starts, or a sudden jump in electric bills without a change in weather or habits. These are signs of an active fault rather than routine wear, and they are best handled as a repair call so the technician can focus on the problem.
Thermostat habits during the cooling season
Setting the thermostat to a steady, comfortable temperature usually serves the equipment better than large daily swings. Running the indoor fan in the auto position lets the coil drain moisture between cycles, while running it continuously can return some humidity to the air in humid climates. If you prefer continuous circulation for filtration, ask whether a lower fan speed setting is available on your system.
Pets, plants and the outdoor unit
Pet urine is corrosive to the aluminum fins and copper tubing of an outdoor coil, and dogs often choose the condenser as a favorite spot. A small decorative fence set well back from the unit can discourage that without restricting airflow. Climbing vines and dense hedges should be kept clear of the cabinet so the coil can breathe.
Signs your air conditioner is overdue for service
If any of these sound familiar, a tune-up should be scheduled soon.
Longer run times
The system takes longer to reach the setpoint than it used to.
Weaker airflow
Vents deliver less air, often due to dirty coils, blowers or filters.
Higher summer bills
Rising costs can reflect dirty coils or a declining charge.
Musty smells
Odors at start-up may point to moisture problems in the drain pan or coil.
No service last year
Skipped maintenance allows wear to build up unnoticed.
Outdoor unit caked with debris
Grass clippings and cottonwood fluff restrict airflow through the coil.

If a repair is advisable, you get a flat price and decide whether to proceed.
What affects tune-up pricing
Tune-ups are priced as a flat service. A few factors can change the scope.
| Number of systems | Homes with more than one air conditioner need separate service for each. |
|---|---|
| Coil condition | Heavily soiled coils may require additional cleaning time. |
| Access | Attic air handlers and rooftop units can take longer to reach. |
| Additional repairs | Any repairs discovered are quoted separately for your approval. |
| Filters | Replacement filters can be supplied at an added cost if requested. |

Notes from seasonal maintenance visits.
The technician found a capacitor that was already well below its rating. Replacing it in April probably saved us a July breakdown.
I liked getting the actual readings on paper. It makes next year's comparison easy.
Our drain line was nearly blocked. They cleared it before it could overflow into the ceiling.
AC tune-up questions
Common questions from Alamance, NC homeowners.
Once a year, ideally in spring before the cooling season begins.
Most visits take about an hour or a bit longer, depending on the system's condition and access.
Clean coils and correct refrigerant charge help the system run closer to its rated efficiency, which can reduce energy use compared with a neglected system.
Only if readings show a need, and only after explaining that low refrigerant indicates a leak that should be found and repaired.
Many manufacturers expect regular maintenance. Our recorded readings help document it.
