What are signs your AC unit needs to be repaired?
Get in touch with an AC repair specialist if you notice the following signs:
- Rising energy bills: Consistently higher or steadily rising energy bills may mean your AC system is using more energy than usual. The average local spending on energy is $108 per month, according to data from the Department of Energy (DOE) and U.S. Energy Information Administration (EIA).
- Inconsistent temperatures: A well-functioning AC system should keep your home at a consistent temperature. Major temperature differences between rooms may signal an issue with your HVAC system.
- Inaccurate thermostat readings: Your home's internal temperature should match the thermostat. Conflicting readings could mean there's a problem with your AC system or thermostat.
- Leaks around the AC unit: Call an air conditioning repair company immediately if your AC is leaking. This could be due to leaking refrigerant or water from a damaged or obstructed tube.
- Weird noises: Loud sounds or unusual noises, such as clicking, screeching or bubbling, can mean a serious issue.
- Strange odors: An AC will typically let off a smell after going unused for months, but it's unusual for an in-use AC system to develop a sudden weird smell.
- Weak airflow: If your AC has weak airflow, that's a sign your air conditioning system isn't working properly or the duct or vent is blocked.
- Warm air: There could be a problem with your home’s ductwork, or your system's compressor could be low on refrigerant if your AC is blowing warm air.
- Frequent cycles: It's normal for your AC to turn on more often on warmer days, but if it turns on and off more than usual, your AC may need a tune-up.

How do you choose the best AC repair company in St. Louis?
Consider these factors when trying to find an AC repair company in the St. Louis area.
Make sure the company is licensed in Missouri
Make sure your AC company has proper licensing and insurance before booking. Missouri HVAC technicians don't need a state license, but it may be required locally. Other requirements include a surety or cash bond and worker’s compensation insurance. Additionally, the Environmental Protection Agency (EPA) requires all HVAC pros who handle refrigerants to be certified.
Look for national accreditations
Accreditation isn’t required, but it offers proof of the HVAC pro’s ability and knowledge in the field. Two professional accreditation organizations include the Air Conditioning Contractors of America (ACCA) and the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE).
Get a free estimate
Most AC repair companies offer free estimates where a professional visits your home to diagnose the problem, offers solutions and gives you a quote. Take note of how comprehensive the company is during the assessment.
Compare costs
Obtain itemized estimates from several companies. Multiple estimates will also give you a better sense of the average price range in your area. Be wary of offers that are too high or too low.
Assess experience
The AC repair technician you choose should be familiar with the type of work you need done. HVAC pros generally have experience with many AC systems, but some specialize in specific brands.
Read reviews
Ask your friends and family if they have any recommendations for local AC repair companies. Always check a company’s online reviews.
Feedback helps you get a sense of what kind of customer service and work quality you can expect from the company. Keep an eye out for consistently bad reviews or a recent increase in poor ratings.
What are popular types of AC units in St. Louis?
The following AC unit types are the most prevalent in St. Louis:
- Central: Standard central AC units are common in St. Louis, as they efficiently cool your entire home.
- Ductless mini-split: The ductless mini-split is a solid choice for homes without ductwork.
- Hybrid: Hybrid systems combine heat pumps with furnaces to provide both heating and cooling.
- Heat pumps: More homeowners in St. Louis are opting for heat pumps, which are more cost-effective in warmer climates.
