"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.

"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."

"One of the machines is called an air handler. I don't know if that's the one that is outside or inside. We have the big fan that moves the air placed outside and there are 2 big pieces. I found Prestige in our phone book and I just got lucky. Our air-conditioner broke down on a Friday afternoon and even though it was November, it was quite warm here in South Florida. The gentleman came later in the afternoon around 5 o'clock. He measured everything, checked out the old air-conditioner and told us that the motor had burnt out. We wondered what the smoky smell was. He replaced both the outside and the inside pieces. They came out even though it was at the end of their day to see if they could fix it to make it last through the weekend. Of course they couldn't with the motor being burnt up. They measured everything square footage to the house and let us know what was available that they had that they could bring out the next Monday. They gave us the Florida break. It was like a rebate, the max p&l, for putting in a new A/C. He made sure we had the paperwork for that and gave it to us right on the billing. A crew of people came the next Monday and took all the old stuff out and put in the new stuff. They completed the work in 2 hours and we had A/C."

"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!!"

"Took his time to resolve the issue and went the extra mile to make sure our air conditioning was working right! Great work and will be keeping their contact for future needs."
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.
