"Had our old furnace and air conditioning system replaced with a new system. Shane is very knowledgeable and was very thorough in making sure everything was right. Was very patient in answering our questions. Properly sized our new unit so our air flow is much improved over the old system. From the first call quickly responding to our request for a quote from Home Advisor, to a follow-up visit to make sure we were well-pleased with the install, Shane and Brock were very professional and performed excellent work."

"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."

"Excellent service. Oscar and his crew go far and above what is necessary to fix or replace plumbing. They are very conscientious, courteous and respectful. They are also very considerate of your property, taking measures to insure that floors are kept clean and all debris is removed when they leave. I will hire Rardin Plumbing and Heating again, and I highly recommend them.

"Almost immediately upon my request for service (via the website) I received a response, and I got excellent service from that point forward through completion of the project. Each individual I spoke with and met face-to-face was a professional and expressed their desire to expedite my order even during a time when it was very hot here, and I knew their workload was heavy. I'm extremely satisfied with the new A/C and expect to be happy with the new furnace when it gets cold here. Thanks for your diligence and an overall excellent job! David Cantrall"

"Got my ductwork cleaned out and replace 23 outlet covers. All done in record time. Very friendly and professional and explained the whole process as he went and showed me all the junk that came out of my ducts. Cleaned up as he went along and couldn't even tell he had been here except that there's no dust floating around in the air now."
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.
