Reliable and Affordable Home AC Maintenance Services From a Source You Can Trust

The importance of scheduled maintenance cannot be understated — this quick tune-up completed by a professional HVAC technician 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, or continuous running of the air conditioning unit when it is not warm outside, 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 the Gaston 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.

OUR EXPERT TECHNICIANS ARE HERE FOR YOU

Air Conditioning Tune-Ups To Keep Your AC Effective and Efficient

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.

I had my spring maintenance completed by Dilling and they do an absolute thorough job! They cleaned everything and tested the heat and AC. They did a thorough inspection to check for any issues.

Dilling now provides plumbing service which is the service they provided for me today. They are wonderful! The receptionist promptly scheduled my service the same day. It was so refreshing for the technician to expertly, efficiently and knowledgeably repair exactly what was needed and not try to sell me something else. Kenny, the technician, was professional, courteous, kind and fair. This is the company that I will now always call for plumbing, heating and cooling. I highly recommend them!

Heat went out on a holiday weekend and Dilling was there same day. The service tech explained what he found and made the repair on the spot. The day before, I called a different company and they tried to convince me I needed to replace the entire system. Glad I got a send opinion from an honest company!!! They just earned all my business and all my referrals.

Our air went out two days ago. I looked up heating and air repair and Dillons H&A came up and I noticed the high ratings. When I called they promptly answered. She told she could have a tech out here in a few hours. Well, they actually showed up in an hour. He went and worked and inspected my system. Unfortunately it’s to old to do anything with so he set me an appointment up with a salesman. This is where it went really well. We met with Matt and Chris. They were very knowledgeable about their products. They explained everything to us in a language we could understand. Did not push us in making a decision and now they are coming back in two days to install a brand new system. Ask about the new lease program. Great experience!!

Dilling’s skilled installers removed degraded and damaged ducts from crawlspace, installed new ducts and a “boot” required on one. The difference in the ability of our furnace and central air conditioner to maintain proper temperatures quickly and economically is now well-proved. 5 stars.

Wess from Dilling Heating and Air came out due to our heating system not working at all. He was a very nice person and very easy to understand what the problem is. We are waiting on the salesman to come out this evening to set up the plans and appointment to have a new system installed. Dilling Heating and Air is very fortunate to have such a smart young man for an employee! Dylan was great too! He explained all the options to us in a way we could easily understand. You guys are very lucky to have them both!!

Air Force did a great job of installing a new hot water heater, expansion tank and water pressure relief valve. Air Force was very professional and knowledgeable as he carefully went about his work. I was very pleased with his work as he communicated with me throughout the installation regarding what stage of work he was doing.

Electrician Vince did a quick and clean job of installing our ceiling fan in our family room. Within an hour we were up and running. He also checked out other electrical system and fire safety aspects of the overall condition of our 60 year old home and made good suggestions for upgrades while providing and reasonable estimate for what it will cost.

Seth Was very professional, attentive and friendly during the check up and easily found out what was wrong with our heater. No one should have to wait around in a house that's 60 degrees in the morning. We would 100% recommend them to our family and friends if they have any issues with heating or cooling. Thank you so much!
