Hi! My name is Devon, I am 21 years old and a soon to be father. I work full time at a paper mill and I am looking to launch my own business taking care of the residents of northeast Florida who need all different kinds of services. I specialize in junk and waste removal, but offer services such as property cleanup and management as well as exterior pressure washing and certain demolition. I appreciate any future business opportunities given to me by the great community of this state. God bless America!

"We are really pleased with Jonco Air. Correctly diagnosed our problem and has us repaired in one 102 degree day. Complementing this was a fair and reasonable price. With Jonco Air, compared to several competitors we consulted, you get more than you pay for. Professional, knowledgeable - we have found our a/c guy."

"Phil's team did a great job. They were punctual. They kept their work area clean, and left the place looking like it did before they came. The guys were professional, and Phil followed up with me at my home after the install to do a final inspection of the work. Phil got me significantly increased air flow for a marginal additional cost. This was probably the best part of the service. He understands how to maximize the system. I will definitely use Energy Sharks in the future, and I have already recommended them to others."

"Mr. Ferrell first connected his computer to my computer via internet and worked for quite a few hours trying to determine what exactly was wrong. The next day he continued working from his computer for several hours. He determined he would have to have my desktop tower to complete the repair. He and my son met in Huntsville to exchange the tower. He then cleaned up a lot of what was wrong and reloaded Windows 10. He deleted the D: drive which had way too much memory allotted to it. The tower was returned and I plugged it all back together and it is working better than it did when I first purchased it. I would use him again and I recommend him highly to anyone needing computer updating and/or repair. His work is warrantied and he is very personable, knowledgeable, and helpful."

"Greg and his team are great, Shaheem was very knowledgeable and friendly, their prices were good and they were always on time. With all do respect to them, I hope I don’t have to use them again as they installed a new Furnace and AC condenser, but if I have any HVAC concerns, I will be using them again."

Most professional HVAC technicians require two to three hours to complete an expansion valve replacement. The timeframe depends on your unit's accessibility and whether additional repairs are needed. The process involves recovering refrigerant, removing the old valve, installing the new component, and recharging the system. Scheduling during less busy seasons may result in more convenient appointment times.
Operating your air conditioner with a malfunctioning expansion valve isn't advisable. Continuing to run the system could potentially damage other components, particularly your compressor, which is significantly more expensive to replace. If you notice performance issues like inconsistent cooling or unusual noises, it's best to have your system inspected before continuing regular use.
Expansion valves don't have a standard replacement schedule, as their longevity depends on system usage, maintenance frequency, and environmental factors. Regular professional maintenance helps identify potential valve issues before they cause system failure. Having your HVAC system serviced annually allows technicians to monitor component condition and recommend preventative replacements when necessary.
Refrigerant leaks require prompt professional attention. If your expansion valve is leaking, you'll likely notice reduced cooling performance and possibly hear hissing sounds near the unit. Addressing leaks quickly prevents further system inefficiency and avoids the environmental impact of released refrigerant. Your HVAC technician will need to repair the leak and recharge the system with the proper refrigerant type and amount.
Because many AC issues present similar symptoms, professional diagnosis is recommended. Problems like inadequate cooling, inconsistent temperatures, or strange noises could indicate expansion valve issues, but might also stem from refrigerant leaks, electrical problems, or airflow restrictions. A qualified HVAC technician has the tools and expertise to accurately identify the root cause and recommend appropriate repairs.
