Home AC Maintenance​

It is very important that you have regular maintenance and service performed on your existing air conditioning unit. The importance of scheduled tune-ups cannot be understated, as they will ensure you get the most out of your air conditioning unit. Dilling offers comprehensive service plans and yearly tune-ups for home AC maintenance


There are many factors that may indicate it is time to schedule home AC maintenance. If you notice a spike in your utility costs, reduced cooling in the home, continuous running of the air conditioning unit when it is not warm outside, these are all indications it may be a good idea to have the air conditioning unit inspected and serviced.


Dilling offers a wide range of preventative maintenance services in Gaston, Cleveland, York, and Mecklenburg counties as well as the greater Charlotte area, for your home AC unit. Our certified technicians will thoroughly inspect and determine any servicing requirements to keep your home AC unit well-maintained and operational.

Air Conditioning Tune-Up​

When you schedule a home AC maintenance service with Dilling, our certified technicians will come out and evaluate your air conditioning unit. After a comprehensive analysis of the unit, our technicians will perform a thorough service and tune-up of the air conditioning system. By keeping your air conditioning system well maintained, you’ll not only enjoy a cooler home or business, but you also gain the benefits of:


  • Boosted AC unit performance: preventative tune-ups of your air conditioning system will allow you to cool your home effectively without extended usage cycles during warm weather spells. 
  • Energy efficiency and lower energy bills: a well-maintained air conditioning unit will save you money and decrease energy consumption in the long-term.
  • Reduced risk of a significant AC unit breakdown: regular maintenance will help avoid the possibility of a major problem arising when you need your air conditioner the most.
  • Improved indoor air quality: by regularly servicing your home air conditioner, particulate matter and dangerous mold and mildew can be spotted before it begins to affect your indoor air quality.

Our technicians can effectively fine-tune your AC unit to work as it should, replace dirty filters, and ensure the airflow is sufficient.


If you have not scheduled routine home AC maintenance for your air conditioning unit, it is imperative to do so to avoid costly repairs in the future. Our technicians will utilize the latest diagnostic tools to determine the needs of your home air conditioning unit. With thorough testing and visual inspection, Dilling technicians will be able to quickly and efficiently pinpoint areas of concern and work appropriately to correct them.
