Here in Raleigh, NC, our HVAC systems go all out to make our homes warm and cozy, fighting the hot humid summers and cold winters. At the heart of your air conditioner and heat pump's cooling (and heating) cycle is the refrigerant, still better known by its old-fashioned brand name, "Freon." While many homeowners may see refrigerant as something that's just "used up" over a period of time, in reality, it is contained within a closed system. This implies that if your system is running low on refrigerant, it's not because it's been "eaten," but because there's a leak.
Low levels of refrigerant are a common but serious problem that can significantly impact your system's performance, efficiency, and lifespan. The good news? Raleigh NC HVAC maintenance is your best defense against them. At Ultra Air Heating & Cooling, LLC, we understand the critical role refrigerant plays, and our comprehensive maintenance service is designed expressly to prevent, detect, and correct such problems to get your system performing at its best.
Refrigerant is a proprietary chemical compound that constantly loops around in your HVAC system, changing from liquid to gaseous state. Its only job is to absorb heat inside your home and release it outside (in cool mode) or absorb heat from the outside and release it inside (in heat mode using a heat pump). This heat transfer is what conditions your air.
A word of caution: newer heating and air systems use refrigerants like R-410A (Puron), while the older systems might still have R-22 (Freon), which is being phased out of manufacturing due to environmental concerns. Regardless of type, your refrigerant is never "consumed." When it gets low, it is clear sign of system leakage, and it needs to be found and fixed, not just "refilled."
Operating your air conditioning unit on low refrigerant will cause a series of negative consequences:

No. Refrigerant is a hazardous chemical and is under high pressure. Handling it requires specialized equipment and EPA certification. More importantly, if your system is low on refrigerant, it means there's a leak that needs to be repaired first, not just refilled.
Refrigerant levels are usually monitored in your annual professional HVAC service Raleigh NC (spring for air conditioning, fall for heat pumps). This periodic check alerts to leaks early.
Some common signs include your air conditioner blowing warm air, the indoor evaporator coil icing up, a hissing sound close to the unit, increased energy bills, or your system taking longer to cool/heat.
Yes. Older refrigerants like R-22 (Freon) and newer ones like R-410A are potent greenhouse gases which, once in the atmosphere, contribute to climate change. Handling and leak repair are hence critical.
Yes, a professional and comprehensive hvac maintenance Raleigh NC from Ultra Air Heating & Cooling, LLC always includes a check of the refrigerant levels as part of our comprehensive inspection process.
Low refrigerant issues are a threat to the operation of your HVAC system, your budget, and even the environment. But with routine, professional HVAC maintenance Raleigh NC, you can avoid them in large measure or detect them before they become major issues.

What Is Freon (Refrigerant) and Why Is It So Essential?
Refrigerant is a proprietary chemical compound that constantly loops around in your HVAC system, changing from liquid to gaseous state. Its only job is to absorb heat inside your home and release it outside (in cool mode) or absorb heat from the outside and release it inside (in heat mode using a heat pump). This heat transfer is what conditions your air.
A word of caution: newer heating and air systems use refrigerants like R-410A (Puron), while the older systems might still have R-22 (Freon), which is being phased out of manufacturing due to environmental concerns. Regardless of type, your refrigerant is never "consumed." When it gets low, it is clear sign of system leakage, and it needs to be found and fixed, not just "refilled."
The Damaging Effects of Low Freon
Operating your air conditioning unit on low refrigerant will cause a series of negative consequences:
- Reduced Cooling/Heating Capability: With minimal amounts of refrigerant, your system is not able to absorb and transport heat effectively. This means taking a significantly longer time to cool your home during summer or heat it during winter (in the case of heat pumps). Your system runs for a longer period of time and uses more energy to achieve the target temperature, which in turn means higher bills.
- Additional Wear and Tear on Components: The compressor, sometimes called the "heart" of your HVAC system, only has a predetermined amount of refrigerant that it can work with. If there is low refrigerant, the compressor must work harder, thereby generating more heat and friction. All this stress can lead to premature wear, overheating, and ultimately a very costly failure of the compressor, which is generally the most expensive component to fix. Refrigerant also has the oil which lubricates the compressor, thus if there is low refrigerant, then there will be less lubrication.
- System Freezing Up: This is a common and clear indication of low refrigerant. When there is insufficient refrigerant to pick up the indoor air's heat effectively, the evaporator coil will get too cold and make the moisture in the air condense and freeze on the coil. A frozen coil is an air obstruction and also reduces cooling capacity, eventually causing hot air to blow from your vents. A frozen coil can also cause water leaks once ice melts off.
- Environmental Impact: Refrigerants are potent greenhouse gases. One leak contributes to the environmental harm, i.e., ozone depletion for R-22 and global warming for R-22 and R-410A. Due to these environmental concerns, venting the refrigerant into the air is illegal, and "topping off" a leaking system without fixing the leak is not only an economy of waste, but also non-compliant to EPA regulations.
How Regular HVAC Maintenance Raleigh NC Prevents Low Freon Issues
This is where Raleigh NC professional HVAC maintenance steps in. Tune-ups aren't just about making your system operate more efficiently; they're about preventing and catching refrigerant leaks early:
Early Leak Detection
As part of our comprehensive Spring Maintenance, our technicians "Check the refrigerant levels." For heat pumps, we also "Check the refrigerant levels" as part of Fall Maintenance. This involves:
- Pressure Checks: Refrigerant pressure tests to check for low levels.
- Visual Inspection: Searching for characteristic indicators of oil residue near coils, valves, and connections, which is commonly seen with a refrigerant leak.
- Utilizing Leak Detection Tools: Utilizing equipment specific to detecting small, elusive leaks before they develop into full-scale issues.
- Squashing a small leak early provides an isolated repair, avoiding a complete system failure and large-scale environmental release.
Optimizing System Health
Maintenance takes care of multiple causes that will strain your system and be possible precursors to leaks:
- Airflow Management: By ensuring proper airflow (e.g., filter checking and replacing, visual ductwork inspection), we prevent coil freeze-up, which otherwise can hide or compound refrigerant issues.
- Coil Cleaning: "Clean the indoor coil (if accessible)" prevents soiling, enabling clean heat transfer and reducing the load on the system, hence reducing the likelihood of parts failure and leaks.
- Electrical and Drain Line Tests: With all of the components operating at peak performance maintains system-wide stress to an absolute minimum, resulting in seal life and integrity of the sealed refrigerant system.
Professional Recharge & Repair
In the event that a leak is found, Ultra Air Heating & Cooling, LLC's experienced technicians are trained to:
- Correctly determine the source of the leak.
- Perform the necessary repairs to seal the leak.
- Efficiently evacuate the system.
- Charge it with the right kind and amount of refrigerant as specified by the manufacturer.
- This complete solution, part of our "affordable high quality HVAC repair and replacement" policy, ensures the problem is permanently solved, not just temporarily masked.
