FAQs
What exactly is an A/C refrigerant recharge and why might I need one in Evensville?
An A/C recharge is the process of adding the correct type and amount of refrigerant to your air-conditioning system so it can absorb and release heat efficiently. Over time, tiny leaks, vibration, or worn service valves can allow refrigerant to escape. In Evensville’s hot, humid summers, low refrigerant means longer run times, higher electric bills, and warm supply air. A recharge restores factory-specified pressures, protects your compressor from overheating, and helps your system reach setpoint faster.
How can I tell if my air conditioner needs a recharge instead of a different repair?
Typical warning signs include warm or mildly cool air from the vents, ice buildup on the outdoor unit or refrigerant lines, unusually long cooling cycles, and a sudden spike in energy usage. During our service visit we measure suction and discharge pressures, superheat, and subcooling. If those readings confirm a refrigerant deficiency and no major mechanical problems are present, a recharge (plus leak detection/repair) is recommended. If pressures are normal, we look for airflow restrictions, thermostat issues, or electrical faults instead.
How often should an air-conditioning system be recharged?
Unlike motor oil, refrigerant is not consumed in normal operation, so there is no schedule such as “every two years.” A properly sealed system can run for decades without adding refrigerant. If you find yourself needing frequent recharges, there is an underlying leak that must be located and repaired. We use electronic sniffers, UV dye, or nitrogen pressure testing to pinpoint leaks so you won’t need another recharge next season.
What refrigerants do you carry and is R-22 still available in Evensville?
Most residential systems installed since 2010 use R-410A, which we stock on every service truck. Older units may use R-22. Because R-22 production was phased out by federal law in 2020, it is now only available as reclaimed or recycled product and costs significantly more. When we service an R-22 system, we will quote the recharge price and also discuss long-term replacement options, such as a new R-410A or R-454B heat pump, which will be more efficient and environmentally friendly.
How long does a typical A/C recharge take and will I be without cooling?
For most residential units, a full diagnostic, minor leak repair, and recharge can be completed in 60–90 minutes. We pull a deep vacuum to remove moisture and air before charging by weight, ensuring accuracy to within a few ounces. Your system can usually resume cooling immediately after we verify pressures and temperature differential, so downtime is minimal.
Do you also handle heat pump and furnace issues while you’re here?
Yes. Our certified technicians are cross-trained in air-conditioning, heat pumps, gas furnaces, and electric air handlers. If your Evensville home uses a single outdoor heat-pump unit for both heating and cooling, we can recharge it, check reversing-valve operation, inspect the auxiliary heat strips, and perform a full fall/spring tune-up—all during one service call. That saves you time, reduces overall labor cost, and ensures year-round comfort.
