Air Conditioning Tune-Up in Woodstock, GA
A tune-up is not a visual inspection and a filter change. Ours is the full multi-point check with meters on it: charge verified against target subcooling, amp draws compared to nameplate, capacitors read against rated value, static pressure measured, drain flushed and the float tested wet. You get the readings.
What's included
- Condenser coil condition assessed and cleaned as needed
- Refrigerant charge verified against the manufacturer's target subcooling or superheat
- Compressor and condenser fan motor amp draws compared to nameplate
- Run and start capacitor microfarad readings against rated value
- Contactor points inspected
- Evaporator coil checked for fouling and frost pattern
- Condensate drain flushed, trap checked, float switch tested wet
- Total external static pressure measured, and the supply-to-return split taken at the plenum
How the visit actually goes
Outdoor first, while the system runs
Electrical readings have to be taken under load, so the unit runs while we work. Coil condition, fan blade and bearing play, contactor, capacitors, and amp draws against the nameplate.
Then the refrigeration side, properly
Charge verified against the manufacturer's target subcooling or superheat for the metering device you actually have — not against a pressure that somebody remembers as correct.
Indoor: airflow, coil, and the drain
Static pressure across the air handler, blower wheel condition and amp draw, evaporator coil, and the condensate system flushed with the float switch tested wet. A float switch nobody has tested is a float switch nobody knows about.
You get the numbers
Every reading, written down, with last visit's beside it if we have been before. A capacitor drifting year over year is visible in that comparison and invisible in a checkbox.

Questions people ask before booking
When should I have the air conditioning serviced?
Spring, before the first genuinely hot week. In this climate systems want looking at twice a year — cooling in spring, heating in fall — which is exactly why the Comfort Club's Gold tier includes two visits.
What does a tune-up cost?
There is a flat price for a single system, and it is included in every Comfort Club tier. We tell you the number on the phone. A second system in the same house is priced per system, and we say so before you book rather than on the invoice.
Will a tune-up lower my power bill?
It can, and we are not going to put a percentage on it. A system running on a low charge, a dirty coil or a restricted duct uses more energy than the same system running right, and how much more depends on how far out it was. Anybody quoting you a number for your house has not measured your house.
Do I need a permit?
No. Maintenance is not permitted work.
Do you do this on systems you did not install?
Yes, on any residential brand, and it is often the visit where we find what the last shop left behind.
