HVAC Maintenance & Tune-Ups in South Fulton
Most breakdowns start small: a filter packed with pine pollen, a drain line slowly clogging, a coil caked in dust. A tune-up catches them early. We service AC, furnaces and heat pumps across South Fulton and nearby towns.
Overdue for service?
Until it is fixed: Leave refrigerant lines and the unit's access panels alone. Those checks take a tech's gauges and meters.
Is HVAC maintenance really necessary?
Yes for most homes in South Fulton. The climate puts a lot of strain on the equipment. Spring is a good time to check the cooling and fall for heating (ENERGY STAR). The ASHRAE design dew point in the summer is 73.3F meaning the drain line will be moving a lot of water. A slow blockage can trip the float switch or overflow. The filters will be full of pine pollen from late February until May. The peak is late March to mid April. Many systems also bake in attics. In Enon the typical home was built around 2004, so original equipment is old. A dirty coil can be the difference between a tune-up and a July breakdown.
What does an AC tune-up include?
You called about a tune-up. We work through ENERGY STAR's checklist, then look at the drain, the filter and the heating side too.
Outdoor condenser during a coil cleaning
Coils and blower cleaned
Dirty evaporator and condenser coils can't move heat well. We clean them and clean and adjust the blower.
Electrical connections and motors
We tighten connections and test motor voltage and current, which can flag a failing part before it quits.
Refrigerant level check
If the level is off, we tell you what we found. Existing R-410A systems can still be serviced.
Condensate drain and pan
Flushed and tested. Georgia Power's own HEIP tune-up checklist includes "Check, clean and cycle condensate drain system."
Thermostat and full cycle
Settings verified, then a full cycle that starts, runs and shuts off cleanly with steady airflow.
Gas and heating check
In fall: gas connections, gas pressure, burner combustion and the heat exchanger, per ENERGY STAR's list.
1-inch filter or 4-inch media filter: which is yours?
Measure the filter's thickness. A 1-inch filter slides into a return grille or slot; a 4-inch one sits in a cabinet by the unit, on its own schedule.
| Filter facts | 1-inch filter | 4-inch media filter |
|---|---|---|
| What it is | A thin pleated or fiberglass filter in a cardboard frame. | A deep pleated filter with far more surface area. |
| Where it sits | Behind a return grille or in a slot at the furnace. | In a cabinet between the return duct and the air handler. |
| Usually found in | Most South Fulton homes, behind a hallway return. | Systems built with a media cabinet at install. |
| What failure looks like | Gray, caked with dust, or bowed into the slot. | Pleats packed with dust and weaker airflow at the registers. |
| What the repair needs | A new filter of the same size, checked monthly. | A matching media filter; the size is printed on the frame. |
What a system overdue for maintenance looks and sounds like
- Water in the drain pan or a damp spot near the indoor unit.
- A yellow filter after pollen season. Atlanta's count hit 5,902 on March 24, 2026.
- Longer run times and higher bills with no change in the weather.
- Rattling or squealing from the outdoor unit or the blower.
- Rooms that used to feel even now feel sticky.
Two or more? Change the filter first, then book a tune-up by phone or form.

What does an AC tune-up cost?
About $80 to $200 for a single visit is typical in metro Atlanta. Your quote depends on what we find: the type of system, how easy the attic or closet is to reach, and whether the coils need a deep cleaning.
What is the most common HVAC problem?
Often a dirty filter, the one fix that's yours. ENERGY STAR: "A dirty filter can increase energy costs and damage your equipment, leading to early failure." Refrigerant and electrical parts are a tech's; capacitors hold a charge.
4-inch media filters
How is a tune-up different from an HVAC service call?
A tune-up is planned upkeep on a working system: cleaning, tightening, testing. A service call starts with a fault and a diagnosis. Maintenance plans usually bundle two tune-ups a year, one for cooling in spring and one for heating in fall.
What is the most expensive part in an HVAC unit?
The compressor, in the outdoor unit. Its failure usually starts the repair-or-replace talk. Clean coils, a correct refrigerant level and tight electrical connections keep it from working harder than it has to.
When it acts up
How can I tell if my HVAC is going bad?
Rising bills, longer run times, rooms that won't hold temperature, new noises, and water where it shouldn't be. Most of these can wait for a visit with the system running. Water overflowing the pan can't: shut it off and call.
How often should a furnace be serviced?
Once a year, in fall. For electric heat, Georgia Power's HEIP tune-up rebate pays 50%, up to a cap, one per system per year, for its customers who apply within 60 days. Book by phone, 7am to 7pm daily.
