Four months of hard running in the Columbus heat
Your air conditioner sits idle most of the year, then has to carry the full load from June through September. Afternoons averaging 84°F push it to run long stretches, sometimes most of the afternoon, to hold the temperature you set.
A tune-up before that stretch checks the parts that wear from long runtimes rather than short ones. Refrigerant levels drop slowly over time and a system low on charge runs longer to do the same job. Electrical connections loosen from the vibration of a compressor cycling on and off all summer. Franklin County has also logged 79 hail events and 174 damaging wind events over the past ten years, and a bent or dented outdoor unit can lose airflow long before it fails outright. A service visit catches these before the hottest week of the year finds them for you.

A tune-up checks the refrigerant charge, cleans the coils, tests the capacitor and tightens the electrical connections.
In Ohio, HVAC licensing for homes is left to the counties.
What that means in Franklin County depends on the county's own rule, since Ohio does not test or record contractors at the state level. Ohio does define what counts as a home contractor, and that definition includes carrying at least $250,000 in liability insurance. That is not a license and nothing was tested to get it. It is a financial threshold a business has to meet to be defined as a contractor at all.
For a maintenance visit on an air conditioner, the protection that applies everywhere in the country is federal. Any technician who opens the refrigerant side of your system, to check the charge or work on the coil, has to hold EPA Section 608 certification. That credential is issued by the EPA, not the state of Ohio, and it exists because refrigerant is federally regulated. Whatever else applies to this job comes from Franklin County's own licensing rule rather than from Columbus.

- What does AC maintenance include?
- A technician checks refrigerant pressure, cleans the condenser coil, and tests the capacitor and contactor for wear. They also check the coolant lines, look at the condensate drain for clogs, and confirm the thermostat is calling for cooling correctly. The filter gets checked too, since a clogged one makes the whole system work harder. Most of this is done from outside at the condenser and takes less time than people expect.
- How often does an air conditioner need maintenance?
- Once a year, ideally before summer starts. Columbus homes only run cooling from June through September, so spring is the right time to catch anything that needs attention before the heat arrives. A yearly check also matters here because hail and wind are common in this area, and a coil or fan blade that took damage over the winter is easier to catch early.
- Is AC maintenance worth it?
- Yes, because most breakdowns start as small problems that a technician can catch before they leave you without cooling on a 84°F afternoon. A dirty coil or a worn capacitor does not fail all at once, it makes the system strain for weeks first. Catching that during a routine check is easier than dealing with it mid-summer when the unit finally quits.
