"Very experienced crew! I was so concerned that I have to pay a huge amount for replacing the compressor of the AC but I feel so fortunate and thank my Uncle for contacting Orlando Air Conditioning Experts who charged a very reasonable cost for it."

"They ac was broke and they did what they said they would do. The repair man was very friendly and knowledgeable. Be warned this is an expensive service provider and you can get great services with much less cost. They do appear to be honest and knowledgeable, but I will not use them again do to the hourly fees."

"Bill and Derrick worked hard to install attic fans and fixed the 3 ducts that were leaking from my air handler. Fixed batted insulation that was installed incorrectly and installed new baffles and insulation into my attic. They added insulation to the rear if the house as well. They took pictures of before and after. It was well worth the Money and it should pay for itself by lowering my electric and heating bill."

"I have James and Michael on my schedule for the annual AC checkup. After they performed an annual AC check they reviewed a home inspection report concerning the AC. They used pictures to show me the issue, provide a quote and were on time to make the repair, also using pictures to show their work. Finished with a great clean up and an added value price. I would recommend Captain Comfort to anyone in need of AC service and repair."

"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."

"I got several different estimates for replacing my 1992 Carrier central heat an air conditioning Unit. Anywhere from from $20,000 down to $6000. I looked at ratings on Homeadvisor.com and Angieslist, and Shaan at Monarch had the best price and some of the most satisfied customers. The installer Adam and his partner were very professional and willing to answer questions as they were working. After the install Shaan came by and did a very thorough inspection prior to activating the unit for the first time. I am very happy with the Midrange Lennox Elite 16 SEER unit so far. Other other companies wanted to tear out the wall in the heater cabinet,so they could install larger units but Shaan was willing to work with the space I had available. It's very nice to work directly with the owner of the company and not a sales person. Thanks to Shaan and his installers for a great job"

"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."
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.
