"Highly recommend Moreno's HVAC & Electric! Our AC was running constantly without cooling the house. He checked it out, found a leak, and recharged the freon. Our unit is 16 years old, so we thought it was probably time to buy a new one or that it would need major repair, but he saved us from a costly purchase. Plus, the price was super reasonable! As always, he was very professional, punctual, knowledgeable, and friendly!"

"I’m very pleased with my experience! The package unit I had needed replacement and what I had in mind was to move the new unit to a different location which I guessed would be more complicated. With my other quotes I had the sense they weren’t happy about taking that on but these folks basically said yeah, it will be, but this will be a challenge to look forward to. I like that. Beyond that the project was done on time and this new system is great! I’ll be looking forward to having them maintain this system over the years."

Customers say: True professional
"Professional from the start. Landscape Guys met me at my property within a couple days of my initial phone call and easily identified my issue. I was provided with recommendations, quote and availability for install within one day of meeting at my job site. The project install was handled with care and each day they cleaned up after the day was done. I couldn’t believe how the team just kept working in the heat. They took very little breaks and stayed late on day one to ensure they would be able to finish on day two. If you want a professional team to work with look no further than Landscape Guys. They are reliable and do great work. I would highly recommend them for any landscape needs around Huntsville, AL."

"Matthew, who was here from Delta Phoenix, was amazing. Everything he was doing, he made a point to explain it to me, not treating me like someone who wouldn't understand. He also pointed out things that I may need to do down the road. And the best part: I have my air conditioning back :)"

"My home warranty company sent R&M out to my home. The owner, Robert, was kind enough to explain the issue with my AC (in terms I could understand). Got the parts and repaired the unit in a timely fashion. R&M is the only heating and cooling company Iâ ll use now. Wonderful service and kind people!"

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.
