What is AC Maintenance?
AC maintenance is a service where your system is inspected and cleaned to ensure proper operation. With summer temperatures that often reach 90 degrees and above, residents of the Lexington area need air conditioning systems that they can count on to stay cool and comfortable.
Homeowners in Lexington and Central Kentucky need a skilled HVAC company to handle all their air conditioning maintenance needs, and more. We service all brands of air conditioning systems and offer comprehensive maintenance plans to make the process as easy as possible, along with upfront pricing and a 100% satisfaction guarantee.
Why Air Conditioners Freeze Up—And How Maintenance Prevents It?
Did you know that most frozen AC units are caused by issues that routine maintenance easily prevents? Restricted airflow from dirty filters, clogged blower fans, or neglected coils causes evaporator coils to drop below freezing, turning condensation into solid ice. Watch our quick video guide with Logan from GreenBox Heating & Air to learn why systems freeze up and how annual tune-ups protect your system:

How Regular Maintenance Keeps Your AC From Leaking Water?
Water pooling around your indoor furnace or dripping ceiling vents is one of the most common signs of a neglected air conditioner. Over time, algae, dirt, and debris clog your condensate drain line, forcing water to back up and overflow. Watch our quick video explanation on how regular line flushing and coil inspections keep your home safe from water damage:

Benefits of Routine HVAC Maintenance
With day-to-day use in the cooling season, an air conditioner can become increasingly less efficient as dust and dirt accumulate on coils and fans, lubricants dry up, and repeated heating and cooling cycles stress components. Air conditioning maintenance helps to restore the performance of your system, and it can have many benefits:
- Improved comfort: When your air conditioning system is clean and working correctly, it will keep your home cooler, provide better dehumidification, and improve indoor air quality.
- Lower cooling costs: A clean, well-serviced air conditioner will use less energy to keep your home cool, reducing utility costs.
- Greater reliability: A thorough AC inspection and maintenance visit allows our skilled technicians to spot problems early and provide expert care that helps you to avoid unnecessary breakdowns and service calls in the future.
- Longer equipment life: An air conditioner that receives proper maintenance at least once a year will last longer than systems with a poor maintenance history.

AC Maintenance FAQs
How long does AC maintenance take?
In most cases, AC maintenance will take about one to two hours. This will depend on how long it has been since your last service visit, the brand and model of your system, and any issues that may come up.
How often should ACs be tuned up?
A complete AC inspection and tune-up should be done once a year. Ideally, you should schedule it in the spring so that you know your air conditioner is working properly and ready for the summer.
What can cause your AC to stop working?
A malfunctioning thermostat can fail to turn the system on or leave your home too warm. A clogged air filter can interfere with airflow and the heat exchange process, reducing cooling performance or even freezing up the evaporator. A clogged condensate drain can shut the system down when water backs up in the drip pan, and refrigerant leaks or low levels can cause a host of problems, from a frozen evaporator to an overheating compressor that shuts the system off.
