"Chris installed two Mitsubishi mini-split air conditioning/heat pump systems in our home. Chris responded quickly to our request for a proposal. He came to our home in a few days, did a thorough review of our options, explained how the systems work and patiently answered all our questions. He sent us his proposal the same day and his estimate was very reasonable. He installed our system in one day even though it required him to work late into the evening due to a delay in the delivery of the equipment caused by a major traffic accident. Chris is very professional and a pleasure to deal with. We recommend him without reservation."

"We are extremely pleased with the mini split that premier heating and air installed in our home. From the beginning Mike was professional, personable , and efficient. He quickly sent us an estimate, and explained the process going forward. Their quote was fair and we decided to go ahead with the project. They installed everything in a day and a half and we couldnâ t be happier with the new system. They were so friendly and trustworthy as well as very neat. I would recommend premier heating and air with no reservation! Thank- you so much!"

"We recently hired Branden to fix an issue we were having with our heating system. He came out in a very timely manner and had the problem diagnosed and fixed in a very short time. He was very professional and explained everything he did and also identified some potential problems we may have in the future and gave us a plan to take care of them. I would recommend this company to anyone having issues with any part of their HVAC system as they are professional, courteous and knowledgeable!"

"Jonathan from Kent County Mechanical did an outstanding job. He contacted me within minutes of my posting for service on Angi. We discussed the issue with my furnace, on the phone and set up a convenient time for him to come by. He diagnosed the problem and reviewed with me the best course of action. Within an hour he sent me a competitive quote. He worked around my schedule. He replaced my old furnace with a superior product; had me up and running in a timely manner. He did all the work himself, from start to finish, he registered my new furnace for warranty, and even provided a dozen filters. Also, he guarantees his work for one year. Jonathan goes above and beyond. I will definitely use Kent County Mechanical again and would highly recommend them for your heating and air conditioning needs."

"When they first came out, they got the AC to stop leaking inside my basement and they clean out some stuff in the system. Then about 3 days later the fan on the condenser kept going on and off. I reached out again and we made an appointment, but no one showed up. Then they showed up unexpectedly 3 days after our scheduled appointment and they fixed the issue."

"Rodney was quick to replace my wall air conditioner. He is very professional, reliable, and gave us a fair price. I would hire him again and would highly recommend him."
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.
