Common signs your AC needs service include warm or weak airflow, strange noises, frequent cycling, unexpected increases in energy bills, and uneven temperatures between rooms. If your system isn't cooling effectively or you suspect something is off, it's best to schedule a professional inspection before a minor issue turns into a major repair.
Costs vary based on the type of issue, the age of the system, and the parts required. At RJ's Heating, Cooling & Water Heaters, we provide transparent, upfront pricing before performing any repair.

Our comprehensive AC tune-up includes:
Routine maintenance ensures peak efficiency, prevents breakdowns, and extends the lifespan of your equipment.
You should schedule AC maintenance once per year, ideally in the spring before heavy summer usage. Annual maintenance helps you catch issues early, avoid emergencies, and maintain energy efficiency. For best results, we recommend joining our Comfort Club Maintenance Plan for regular tune-ups and service reminders.
Yes! Our technicians are trained to service and repair all major AC brands, including Armstrong, Ducane, MagicPak, Carrier, Trane, Lennox, Goodman, Rheem, and York. Whether your system is new or 20 years old, we'll diagnose the issue and provide expert repairs.
There are several reasons your AC might be blowing warm air:
Our team will perform a full system check to identify the cause and get your AC blowing cold air again quickly.
Many older systems use R-410A, which is now being phased out due to environmental regulations. New systems are transitioning to R-454B or R-32, which are more efficient and have a lower environmental impact. If your system still uses R-410A and needs refrigerant, we can still recharge it—but future repairs may become more expensive as supply declines. If you're planning a system replacement, we'll guide you toward EPA-compliant models with the newest refrigerants.
Refrigerant leaks are often caused by corrosion in copper lines, faulty joints, or wear and tear over time. Leaks not only reduce your system's ability to cool but also increase energy costs and can damage the compressor. Our team uses specialized tools to detect and repair leaks, then recharge the system to restore performance.
Yes. We understand that a broken AC during a heatwave can be more than uncomfortable—it can be dangerous. We provide emergency air conditioner repair 24/7 throughout Barrington and surrounding areas, so you're never left waiting for relief.
Skipping maintenance can lead to:
Preventive maintenance keeps your system in top shape and often pays for itself in energy savings and fewer repairs.
Absolutely. Our Comfort Club Maintenance Plan includes:
It's the easiest way to stay on top of your HVAC maintenance and reduce long-term costs.
If your AC is over 12–15 years old, requires frequent repairs, or no longer cools efficiently, replacement may be the better long-term investment. New systems are more efficient, use eco-friendly refrigerants, and come with warranty protection. We're happy to provide a repair vs. replacement analysis to help you decide.
Yes! Clogged or dirty air filters restrict airflow, reduce cooling efficiency, and strain your blower motor—leading to higher energy bills and potential system damage. We recommend checking filters every 30–60 days and replacing them as needed.
