Air conditioning problems happen for many reasons, and it’s better to find a licensed and insured AC repair company than diagnose the problem yourself.

In Cornelius, summertime temperatures average 89 degrees, so repairing your AC system before the heat sets in should be a top priority. Get an AC repair pro in your budget by comparing quotes from multiple providers.

What are signs your AC unit needs to be repaired?
Your AC system needs repairs if you see the following signs:
- Rising energy bills: Higher or rising energy bills may indicate your AC system is using more electricity than usual. The average spending on energy is $110 per month in Cornelius, based on data from the U.S. Energy Information Administration (EIA) and Department of Energy (DOE).
- Inconsistent temperatures: Your AC system should keep your home at a consistent temperature. Fluctuations in temperature from one room to the next could point to an issue with your HVAC.
- The internal temperature doesn’t match the thermostat: Differences between the thermostat's temperature and your home's actual temperature means there may be a problem with the thermostat or AC system.
- Leaks around the AC unit: Liquid dripping from the AC system is an issue. This could be leaking refrigerant or water from a damaged or blocked tube. Either way, contact an AC repair company immediately.
- Weird noises: AC units will typically produce some level of noise, but loud or unusual noises can be a problem. If you hear bubbling, screeching or clicking, call a professional.
- Strange odors: An air conditioner will typically give off a smell after months of disuse, but it's unusual for an in-use AC to develop a sudden bad scent.
- Weak airflow: A sign your AC system may need repairs is weak airflow. An inefficient AC or blockage could lead to weak airflow.
- Warm air: Warm air indicates a potential problem with your home’s ductwork or that your system's compressor is low on refrigerant.
- Frequent cycles: Your AC cycling on and off more often than usual may indicate an issue. Your system should turn on more on warmer days, but it shouldn’t do so constantly throughout the day.

How do you choose the best AC repair company in Cornelius?
Consider these factors when trying to find an AC repair company in Cornelius.
Make sure the company is licensed in North Carolina
Verify that your AC repair company has licensing and insurance. The North Carolina State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors requires HVAC contractors to maintain proper licensing. HVAC technicians who handle refrigerants must be certified by the Environmental Protection Agency (EPA). Other requirements include a surety or cash bond and worker’s compensation insurance.
Look for national accreditations
Some AC technicians pursue optional national accreditations from professional organizations such as the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) and the Air Conditioning Contractors of America (ACCA). While not mandatory, accreditation offers proof of the technician’s skill and expertise in the industry.
Get a free estimate
The norm among AC repair companies is to provide free estimates in which a professional assesses the problem, offers solutions and gives you a quote. Pay close attention to how thorough the technician is during the assessment.
Compare costs
Obtain detailed estimates from multiple providers. Multiple estimates will give you a better sense of the average price range in your area. Don't base your decision soley on the lowest price because their quality of work may be lower than others.
Assess experience
Make sure the company has experience handling your kind of AC system. Some HVAC pros specialize in certain types of systems, whereas others have more generalized experience.
Read reviews
Ask friends and family for AC repair company recommendations. Always look up online reviews for professionals you're considering hiring.
When browsing reviews, watch out for consistently bad ratings. Read primarily current reviews, as the company's work quality could have changed over the years.
What are popular types of AC units in Cornelius?
Here are the most common types of AC units in Cornelius and the homes they work best for:
- Central: Standard central AC units are very common in Cornelius, as they efficiently cool entire homes, making them well-suited for hot climates.
- Ductless mini-split: The ductless mini-split is another common type of AC unit. It offers zoned cooling without ductwork.
- Hybrid: Hybrid systems combine heat pumps with furnaces. They provide cooling during hot weather and heating during colder seasons.
- Heat pumps: More Cornelius homeowners choose heat pumps, which are more cost-effective in warmer climates.
