"Bart Holmes himself came to my home and thoroughly inspected my 18 year old air unit, found the problem an fixed it. Anyone else would have said to buy a new unit. Honesty and 40 years years experience is hard to find and this company has both. Thank you."

"Very impressed with initial visit. We needed someone to come out on a Saturday. Shaun looked at entire system, not just the air conditioner. Quote was in line with othe providers. Installation scheduled quickly (for Monday), installers were very professional. I have already recommended this vendor to friends."

"Great, same day, super efficient. Another company that was first to call me tried to up-sell me on replacing the entire a/c unit instead of topping up the Freon per my request. I said I know things about air conditioning since I am a senior citizen and my systemâ s history, so I was expecting to just get an annual pressure test, routine stuff. So that first guy didnâ t get my business because he failed to respect my preferences and judgement and saying stuff like â R22 is so expensive and itâ s better to change out the unitâ , not realizing I know there are at least four drop-in replacements for R22 today. After that weird phone call, Iâ m glad to have instead used Freezing Pointâ s guy who even with no English ability took care of the job, climbing up on my roof with the refrigerant tank and gauges. I will probably use him again next year for the same service call on my 25 yo. central a/c."

"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."

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.
