"The work was done decent and in order. We hired Dan to assemble a bar and install an outdoor Television inside the bar. He nailed it. Dan was very professional, attentive to the job at hand and had great work ethics. I was very impressed with the detail in which he performed each given task. He did more than what was expected. We found him to be very knowledgeable in his craft. My husband and I are very pleased. We have already referred Dan to one of our friends who buys old houses and fix them up for resale. Dan finished tfw project in a very timely manner. We will be willing to use Dan for future projects as needed. Thanks Angi’s List for recommending such a hard working and dedicated individual to work on this project. Now to get my Hubby to come inside is gonna be my problem…one I must figure out on my own. #Happy Customers"

Will continue using the company to service equipment!"

"They came out right away during the hottest days when everyone was busy and replaced my HCAC system within a couple of days of the initial visit. They repair the our second central air unit that needed a capacitor replaced. First class install!"



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.
