"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."

"From the first phone call Mario was on top of the issue that we had with our old air conditioner. Gave us a great deal, worked in our budget, installed quickly and professionally. Helped to install a smart thermostat and get it working perfectly. Saved us from the Florida heat with a great air conditioning unit. Very professional. We highly recommend him. 5 stars."

"I selected Wesley Whitson AC Heating Services over two other AC Contractors. He made my choice very easy. He was very knowledgeable and honest, answered any questions I had, never rushed or made me feel that I was taking up too much of his time, and always returned my calls very promptly. His price was all inclusive at a significantly lower price than my other quotes for an identical system, and he did not try to add any unnecessary items to the job, in fact, he gave me very good reasons why some of the items I thought I wanted were not really necessary. I also really liked the fact that his quote included the EXACT model numbers of the equipment he would be installing ! I contacted Wes on a Friday afternoon to to schedule the job (a new Amana Heat Pump and Air Handler to replace my dying 17 year old system), and he was able to schedule the job for the next business day ! His crew (Kyle and Zack) showed up on time and as promised, on the following Monday, to install my new system ! I am very happy that I went with the Variable Speed system with Humidity Control and ComfortNet thermostat. Wes was right about the Humidity control keeping things comfortable. We used to set our old system at 73 deg...the new system is set at 77 deg and 55% humidity (as suggested by installer Kyle), and it feels very comfortable (nice and quiet too) ! After the installation was complete, Kyle gave a very good explanation on the operation and settings of the ComfortNet Thermostat. I am VERY happy with my new system !"

"I originally called my regular service company to come out and look at my ac and they told me I had a bad compressor and should replace my 7 year old system. I called Prestige for a 2nd opinion, and they said my compressor was not the problem. They also told me that my system was still under the manufacturers warranty. They repaired my system for under $300. I will definitely be calling them if I have a problem in the future."

FAQs for air conditioning projects in Casselberry, FL

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.
