"Ken arrived promptly on a Sunday afternoon to repair my air conditioner that was not cooling. After having a negative experience with another company earlier in the day who tried to scam me into buying an entirely new $9500 system, Ken was able to diagnose the problem and fix it on the spot for a fraction of the price. He was professional, thorough, and explained everything in detail. I highly recommend Ken and A Breath of Fresh Aire, and I won't hesitate to call them for my future needs!"

"I highly recommend to anyone in the Longwood or greater Orlando area Matthew Roberts Air Conditioning. They are an exceptional company that provides exemplary service. I recently had them install a new Trane air conditioning system and I was completely satisfied with the installation and service they provided. They are a family run business and you could tell they genuinely care about putting the customer first. Since replacing an air conditioning system is one of the biggest expenses homeowners face, I had several concerns going into the process and they made it a point to address all of my concerns and you could tell they wanted me to be happy at the end of the day. They didn’t try to upcharge me into anything I didn’t need as other companies did. My wife even commented that Luke Roberts didn’t seem like the other pushy salesmen we interviewed and was focused on doing what was needed. At the end of the day, I am thankful I trusted Matthew Roberts Air Conditioning with my new investment."

"Had service star Air & heating replace a 5 ton and 2.5 ton and two air handlers that had gone bad. Louis Ratti told me it would take his crew about 8 hours to completed the job from 9:am to 5pm. The crew got there on time and started to work right away. They were professional, courteous and proficient. There was no guessing to what they had to. They were good I say better than good. By 2:30pm they had both systems up and running and the work area clean and spotless. Not only that, I asked if they would connect my phone to both thermostat and with out hesitation they did it. I was very highly impressed. Thank you Louis for sending the right crew"

"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."

"Shaan, was very professional and knew his business. He gave me a lot of choices and didn't pressure me to spend more than I needed. He returned my call fast. He came by many times during the day to make sure everything was being done right. The installers Austin and Manny where the best they worked none stop until they got me up and running. They did things that didn't have to do, but made sure it was done right. I had not had air conditioning for five days and they knew I was ready for air? Thanks!!"

"My AC was on and only blowing warm air. Robert showed up and within 5 minutes was able to find the issue, help explain it to me, replaced the part, and took extra time to inspect the rest of the unit. He ensured everything was working properly again and that my AC was back to blowing cool air. He was quick and very friendly. He didn't try to sell anything or tell me I need a bunch of stuff replaced and I 100% will trust him for future work."

"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.
