"I was so pleased with this company, I wouldn't hesitate to recommend them to anyone. I have a rental property in Casselberry, and my tenant called me at 6:45 pm to say the air conditioner wasn't working. I immediately got on Angies List and began researching air conditioning companies. I was a little panicked, because it was so late, 7:10 pm, by the time I made the decision to call Matthew Roberts Inc, I'm so glad I did. I called and left a message, hoping for a call back first thing Tuesday morning. I was amazed to get a call back at 7:20 pm, from a very nice gentleman named Bill, who said he was only about 20 minutes away, and could go by right then. He explained it would be a higher price for the after hours service call, so I could make the decision to wait. The difference was 35.00 an hour more, and seemed quite reasonable, especially since It was my tenant. Bill went by, introduced himself, and began to diagnose the problem and repair it. My tenant was thrilled with his professionalism and courteous manner. The repair took a little over an hour and was well worth the price. He explained what the issue was to both of us and gave my tenant advice on how to avoid the issue in the future. I will only use Matthew Roberts Inc for any future air conditioning issues I may have.

"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.

"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 !"

"It went great. I worked with Mike and he was more than helpful. I was always able to get in touch with him with any questions and he was honest and informative. I would definitely recommend Mike and Service Star for anyone's air conditioning service or installation."

"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."

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.
