"I couldn?t be happier with the experience. Graham Solution handled the entire installation from start to finish, and the quality of the work was outstanding. He was professional, knowledgeable, punctual, and paid close attention to every detail. The installation was completed efficiently, everything was left clean when the job was finished, and the system works perfectly. It?s hard to find someone who takes this much pride in their work, and it definitely shows. I highly recommend him to anyone looking for reliable, high-quality HVAC installation. Excellent workmanship and great customer service from start to finish!"

"I am happy to write this review about JDL HVAC Services LLC. From start to finish; Amber, who setup my initial appointment was very nice & professional. Ire, the technical associate was prompt, very knowledgeable and got my system working again with a temporary fix. I opted for a new heating unit (which was reasonably priced) and all of the technical associates were easy-going and very professional. They were organized, used protective foot coverings and protective coverings for my floors, and cleaned up after the job. Special thanks to the entire team led by Armando; Jerel, Fernando, Michael, & Conrad. NOW, thanks to JDL HVAC, I FINALLY have a properly installed & functioning heating/air conditioning unit. I highly recommend this company!"

"Mr. Bost did an excellent job for me for a reasonable price. I know he obtained the best deal for me on the furnace and the air conditioning unit. He answered all my questions. He was on the job when he said he would be; he was professional and courteous. The installation went smoothly, and I have had no problem with the furnace or air conditioner since they were installed in 2008."

"I called Kenny at K and K and he was able to come out the same day to install a window air conditioner. This job was challenging because it was a 14,000 BTU unit not a normal slide in type. He did an excellent job on a day temperatures were at 95 degrees. I would definitely recommend this company."

"We contacted Bobby at New Handyman for plumbing services. Bobby was fast, professional, and truly exceeded our expectations considering the job was slightly more challenging than we originally expected. Based off the work done through the New Handyman Angie's List deal, we plan on using Bobby in the future as his calm demeanor and straight forward method of communication was truly a breath of fresh air.

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.
