"Great. Fast response to my inquiry. The two installers did a good job. Left area so clean you would never know that insulation was blown in attic area. Price was good too. Thanks, JMS, we can really tell the difference in the air temperature."

"Service One has been wonderful to work with, both for our plumbing and air conditioning matters. Our A/C had 3 leaks in it, and Duke Energy failed to cover these damages despite the fact I had purchased a coverage plan with them. ServiceOne gave me a great quote and our technician Otto was super knowledgeable, personable and all around a great person whom we felt very confident with. I received another quote from Ferran that was nearly $1,000 more than what ServiceOne quoted, and for a unit that wasn't as efficient. The A/C is working great, they have a great warranty plan for it, and have always been very timely in returning calls in the past. Highly recommend them if you're looking for a good company that is trustworthy and will take their time to talk to you."

"The day after we got electricity back on after Hurricane Irma we were welcomed with an air conditioner that would not cool. Prestige arrived a few hours after calling them on a busy Sunday and quickly assessed the problem. By Monday morning comfort had returned. Although I expect every A/C company to show up and say the same thing "It'll cost $9,000 and 4 weeks to fix or we can sell you a new unit." In this case the unit was installed 14 years ago and it was truly time to move on. Prestige gave me a great price on a unit and got it installed right away. The workers were professional and it was obvious they took pride in their work and respected the company and owner. As a nice bonus, the new unit also came with a free preventive maintenance visit within the first year. I definitely recommend them and would use them again."

"Woke up around midnight to my HVAC being set to 75°, but all the temperature sensors in my home reporting above 83. So in a panic I reached out to all the AC places in the near area. Novation can in clutch. There were able to come out first thing in the morning after I dropped my kids off and school and their prices were a cheaper than most of the other quotes I received. I really appreciate Jackson. He showed up replaced the capacitor, found and fixed a leak in the copper pipes, and completely recharged the system."

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.
