"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."

"Csaba was here right on time, and he and his assistant were very professional. We hardly knew they were here! We had a new air handler and outside unit installed, and it went perfectly. No high-pressure sales tactics, no surprises, no hidden fees. Just excellent service. I have already recommended them to family, friends, and colleagues, and I will continue to do so. I can't say enough about how pleasant this experience was. What could have been stressful was painless. We were up and running in no time.

"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."

Richie, one of their technicians, spent 3 hours cleaning my coils and explaining what else needed to be done to service my air conditioner. I have been with the company sinve 2017 and am very happy with them."

"Kevin was professional and extremely diligent. Our air conditioner broke during a streak of 85degree plus days. The closest replacement parts were almost 50 miles away. Kevin drove up and back in the rain, returning after 7:00 pm to ensure we had air conditioning."

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.
