Keep Cool with Help from Your Local AC Contractors

A hot, humid Illinois summer is a lot easier to handle when you have a reliable air conditioner. But when that system suddenly starts blowing warm air – or just quits on a 95-degree day—it’s more than an inconvenience. It’s a stressful emergency for your family or your business.

We get it. As Springfield’s trusted, 3rd-generation AC company, R.D. Davis Heating and Air Conditioning is here to get you comfortable again, fast.

Frequently Asked Cooling Questions

What are the signs my AC needs repair?
The most common signs are your AC blowing warm air, making unusual noises (grinding, hissing, or squealing), water leaking around the indoor or outdoor unit, or a sudden and unexplained spike in your energy bills.
Why is my AC freezing up or forming ice on the coils?
This is a very common problem! It's usually caused by one of two things: restricted airflow (like a very dirty filter) or low refrigerant. If you see ice, turn your system off to let it thaw completely and give us a call.
How do I know if I need a new AC or just a repair?
We'll always help you decide. But a good rule of thumb is to consider the unit's age (10-15+ years), the frequency of repairs, and the cost of the repair. If you're facing a major part failure (like an AC compressor replacement) on an older unit, it's often more cost-effective to upgrade to a new, energy-efficient AC system.
How often does my AC unit need maintenance?
We recommend a professional AC tune-up every spring. This annual service allows a technician to clean the coils, check refrigerant levels, and test electrical components. It's the best way to ensure your system is ready for summer, prevent breakdowns, and keep your energy bills low.
