AC Tune-Ups in Greenville, SC
Carolina Heating Service provides AC tune-ups for homes across Greenville and the Upstate. A tune-up is a complete maintenance visit for your cooling system: our technicians clean it, test it, replace your disposable filter with a pleated one, and document its condition. We have served Greenville since 1981.
Greenville’s cooling season is long and humid. A system that starts it with clean coils, a fresh filter, and a verified refrigerant charge has an easier season than one that doesn’t.
Schedule your AC tune-up with Carolina Heating Service online, through our 24/7 website chat, or by phone. You will know your technician before the doorbell rings, see the price before the work, and keep a written report card after. From cool to cozy, We’ve covered Greenville and the surrounding area since 1981.

What Our Air Conditioning Tune-Up Includes
The checklist is long on purpose, and the new filter is part of it:
- We replace your disposable air filter with a pleated filter, included in the visit.
- We clean the outdoor condenser coil, then wash and wax the cabinet to protect the finish.
- We flush the condensate drain to protect against overflow and check the evaporator coil.
- We measure refrigerant superheat and subcooling and record operating pressures and temperatures.
- We test the condition of the compressor contacts and run a megohmmeter test on the compressor itself, an electrical health check on its motor windings.
- We inspect start and run capacitors and relays for bulges, rust, and leaks.
- We meter voltage and amperage in every motor, test for worn bearings, and lubricate moving parts.
- Return and supply air temperatures get tested for the temperature drop, and blower speed gets adjusted.
- We safety test all controls, clean the thermostat, check humidity, and inform you of the equipment’s condition with any recommended repairs.
What Those Measurements Buy You
Our testing reads the compressor’s winding insulation, which can degrade before the compressor fails, and the recorded pressures and temperatures show drift from one year to the next. That record shows how your system is aging.
The cleaning still earns its place. A washed coil sheds heat at design pressure, a fresh pleated filter protects the indoor coil while filtering your air better than a flat disposable one, and a clear drain keeps summer condensate out of your ceilings. Staying on a maintenance schedule also helps satisfy manufacturer warranty requirements.
Why Greenville Chooses Carolina Heating Service
Our technicians document their work with video and leave a written report card on the system’s condition, so the state of your air conditioner is something you can read and keep. Before the visit, you receive a photo of your technician and an on-the-way message, so you know exactly who is arriving.
Every technician completes a multi-month training program at hire, and the right expert gets matched to each job. Upfront pricing means the price is presented before work begins. If the tune-up reveals a repair, our air conditioning team fixes it right the first time, and scheduling runs through online booking, 24/7 website chat, or a call.
What to Expect From Your Visit
Your technician reviews what you have noticed and works the full checklist with the system running. Measurements go on the report card, findings are documented on video, and recommendations come with the price before anything proceeds. Homes with heat pumps are serviced as well.

FAQs
Is the replacement filter included in the tune-up?
Yes. We replace your disposable filter with a pleated filter as part of the tune-up. A pleated filter captures finer dust than a flat disposable one, which helps protect your indoor coil and improves the air the system circulates.
Will I know who is coming to my house?
Yes. You receive a photo of your technician and an on-the-way message before arrival. Every technician on our team completed a multi-month training program when hired, so you know who is at the door and how they were trained.
What does the report card you leave contain?
It documents your system’s condition from the visit, including operating pressures and temperatures, along with any recommended repairs. Kept year over year, it shows how your system is aging, which helps you time repair and replacement decisions.

Yes. Carolina Heating Service works on both residential and commercial properties across the Upstate. Call us to discuss your building and schedule.

Furnace stopped working unexpectedly two days before the holiday weekend and Carolina had a tech out right away. Had to order a new blower motor but expedited it and got it installed next day! Excellent communication and a big thanks to the tech who fit me into his already busy schedule.
