As summer heats up across Knoxville and East Tennessee, your air conditioner is working hard to keep your home comfortable. But if your system is low on refrigerant, it could be costing you more while delivering less cooling—and that can lead to bigger problems down the line. With refrigerant prices climbing due to environmental regulations and supply chain challenges, now is the smart time to address any refrigerant issues before costs go up again.
At Eco Home Solutions, we’re here to help local homeowners stay cool and save with expert refrigerant inspections, leak detection, recharge services, and affordable replacement options when needed.
Recent environmental laws have phased out older refrigerants like R-22 (Freon), making it more expensive and harder to find for older systems. On top of that, supply chain issues and higher raw material costs are driving up prices for all refrigerant types—including modern, eco-friendlier options like R-410A (Puron).
When combined with higher demand during summer, that means:
Running your system low on refrigerant can cause serious damage, especially to the compressor. And waiting too long could mean:
By acting now, you can:
Homeowners in Knoxville, Farragut, Maryville, Oak Ridge, and surrounding areas are already booking their refrigerant checks to stay ahead of the summer heat.
If your AC isn’t keeping up, now is the time to act. With refrigerant costs and repair prices already rising, scheduling service early can help you stay ahead of the heat and the expense.

There are several reasons why an AC unit might not blow hot air. These include clogged air filters, refrigerant leaks, electrical issues, and more. Other causes include blocked registers, ductwork problems, thermostat malfunctions, and furnace issues.
Poor AC airflow can be caused by blocked registers, clogged air filters, duct leaks, fan motor failure, and computer module malfunctions.
Common reasons include low refrigerant levels and dirty air filters. Other issues are frozen or dirty evaporator coils, blocked condenser coils, and closed vents. Problems with the thermostat, clogged drain lines, power issues, and undersized AC units also occur.
Additionally, ductwork leaks, airflow issues, and a dirty or faulty compressor can cause problems.
Dirty air filters can block airflow. This stops the HVAC system from spreading warm air evenly. It can cause the unit to overheat and shut down, leading to no warm air in the home.
Start by checking if the system is running by looking at the thermostat and fuse box. Then, search for any blockages or clogged air filters that might be stopping the airflow.
An air conditioner uses refrigerant to take heat from the indoor air and release it outside. It has a compressor, evaporator coil, and condenser coil. These parts work together to cool the home.
In heat pumps, refrigerant moves warm air into the home during the cold months. If there's a refrigerant leak, the system can't heat the air well. This means there won't be enough warm air.
A capacitor failure can stop the fan motor from running, leading to no airflow from the AC. This issue needs a professional HVAC technician to fix it.
The main parts are the compressor, evaporator coil, condenser coil, and refrigerant. They absorb heat from the air inside and release it outside. This keeps the home cool.
Electrical issues like tripped circuit breakers or faulty wiring can stop the furnace or heat pump from working right. This means the system won't blow warm air.
If the computer module controlling the compressor and fan fails, it can stop the system from blowing air. A technician must replace the faulty module to fix it.
Signs include hissing sounds, visible leaks, and a slow loss of cooling. A refrigerant leak can hurt the compressor and other parts. It's crucial to fix it quickly.
Keeping registers and ductwork clear helps warm air move around the home. If they're blocked, the HVAC system can't circulate the warm air well.
Without a working fan motor, your AC won't blow air. This issue requires a professional to repair or replace the bad fan motor.
A dirty air filter cuts down airflow, making the system work harder. This can stop it from blowing cold air and may damage parts over time.
Ductwork leaks and not enough insulation let warm air escape. This makes it hard for the heating system to heat the home. Rodents can also damage ductwork, causing leaks.
Clogged or leaking ducts can block airflow, making the AC run but not cool the air. You might need professional duct cleaning and repair to fix this.
Dirt, debris, and low refrigerant can freeze the evaporator coil. This limits airflow and reduces cooling power.
Problems with the pilot light, dirty sensors, or a system that's the wrong size can also stop the heating from working right. This means not enough warm air is distributed.
If your AC doesn't cool or blow air, it might have a coil or compressor issue, like a refrigerant leak or a failed compressor. This causes no airflow and cooling.
Closed vents can stop cool air from reaching some rooms. This leads to uneven cooling in the home.
An HVAC system can overheat and shut down for many reasons. These include its age, mechanical failures, or dirt buildup. This can cause a lack of warm air.
Trying DIY repairs can damage your air conditioning system more. It's wise to call a trusted HVAC contractor for quick and correct repairs to avoid bigger, more expensive issues.
Thermostat problems like wrong settings or wiring issues can stop the AC from working right. They can also keep it from reaching the desired temperature.
Try checking the thermostat settings and batteries, replacing air filters, and cleaning the furnace. Make sure the gas supply is good. For complex issues, call a professional HVAC technician.
Regular tune-ups and cleaning by a professional HVAC technician keep your air conditioning running efficiently. This helps avoid airflow issues.
A clogged drain line can cause water to back up, shutting off the AC. This is a safety feature to prevent damage.
