HVAC Services Kalamazoo MI | Call J & J Heating & Cooling

Common signs include reduced cooling power, longer run times to reach your set temperature, ice forming on the refrigerant lines or evaporator coil, and a noticeable hissing or bubbling sound near the indoor unit. If you notice warm air from vents or higher-than-usual energy bills, it's time to call us for a diagnostic. In Kalamazoo's humid summers, a leak can quickly lead to system failure and discomfort.

Short cycling is often caused by an overheating furnace, which can be due to a clogged air filter restricting airflow, a faulty flame sensor, or issues with the heat exchanger. In our local climate, this problem strains your system, reduces efficiency, and can lead to premature failure. Our technicians will pinpoint the exact cause—often a simple fix—to restore safe, steady operation and protect your furnace from unnecessary wear.

In many cases, we can perform a professional repair. Our first step is a thorough leak detection test to locate the source. If the leak is accessible and repairable—such as at a connection point—we will fix it, evacuate the system, and recharge it with the correct amount of refrigerant. However, if the leak is in the evaporator coil or the system is very old and uses phased-out refrigerant (like R-22), a replacement may be the more cost-effective, long-term solution. We'll provide a clear, honest assessment and all your options.
