"Brandon came out right away last week when my heat stopped working. It was a quick fix for him so he gave me a very reasonable price. He wore a mask and was very polite. Iâ ve already recommended him to others and they have had similar experiences with Brand Air. Will continue to recommend Brandon."

"The service was phenomenal. Mike was extremely professional, knowledgeable and very friendly. Just to note: we looked through 4 or 5 local A/C repair businesses, and read reviews before choosing The Air Doctor, Looking for someone to give us an honest evaluation without costing us an arm and a leg. Mike was perfect. Told us every step along the way what he was doing and what needed to be done. Within an hour our A/C was back up running. Just a wonderful experience."

"A.J. installed a new electrical meter panel today. He found the rust and the problem that no one else had. I cannot say enough good things about A. J.. He honestly saved us money and headaches in the long run. He is highly professional, knowledgeable, and personable as well. A. J. finds a way to save us money when it is possible. He always gets right to work and finishes the job well and in a timely fashion. He lets us know every step in the process, takes photos of the work, and communicates well with the home office and Brunswick Electric. He made sure that Brunswick Electric inspected and passed the job. Thank you A.J. and A+ Electric for easing our minds about our home heating and air conditioning and making sure that the house environment is working cleanly and efficiently."

"Chad came out the same day and did a very thorough analysis of the inside and exterior heat/AC unit. He changed the filters and all his recommendations to both me and with my husband on the phone as well about his concerns. We value his expertise and we are very impressed with this company. Glad we made the decision to switch to ARS."
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.
