"The salesman came to our home & was very professional & knowledgeable. We got several quotes but decided to go with this company because of the knowledge of the salesman. The technicians came to install the air conditioning on time, wearing masks, and did a fantastic job. There were no problems whatsoever with the install. They also were very neat & cleaned up after they were done. I definitely would recommend this company!"

"Mike was not only a plumber but also a licensed heating expert. He did arrive 2 hours late since he had an emergency, a call would of been nice to let me know, but once he got here he took care of my problem quickly and professionally. He seemed very competent. He also added a device to help bleed the air from the heating system which should avoid the same problem returning."

"I was very happy with my service call today! The repairman, Scott, was knowledgeable and pleasant and wore a mask and gloves throughout., so I felt safe, despite the pandemic. He serviced both of my central air systems and diagnosed the problem with the malfunctioning one and fixed it. By the time he left my house was already a much more pleasant place to be!"

"This company was without question one of the best we have worked with. Polite, honest about the work to be done and the time frame to get it done. Our Navien boiler/heat combo went on the fritz during a major cold snap and the holidays, a double whammy. They came out that very day. Jared was our technician, he was awesome. Kelley's was able to get the needed part to fix the issue the next day. He came back not only fixed the problem, but waited for 30 minutes before departure checking the system and making certain everything was running as designed. Since the combo system went down during such extreme cold days, extra pressure built up that didn't present itself until the next day. We texted Jared, he not only responded to the text, he called us immediately, on a Sunday and walked us through what turned out to be a simple fix. Things have been running smoothly ever since. Jared was awesome. This is our families team FOREVER!"
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.
