"Matt was prompt and professional and the work he performed was impeccable. We had wall-mounted AC/Heating units installed in a traditional seaside cottage, and he was meticulous about finding non-intrusive ways to run plumbing/electric. He even upgraded to stainless steel hardware considering our corrosive sea air environment. I will recommend him again and again."

"Majic Air did a great job of listening to our desires. We wanted to install central air conditioning in our two story home. We did not want ductless wall units. Shawn, the salesman, was able to come up with a plan that combined traditional ducted AC for the first floor of our home with ductless ceiling cassettes for the second floor of our home, completed with one wall unit for our finished third floor office. We have the air conditioning we wanted and the look we desired. The installers were professional, hard-working, and incredibly neat - leaving us with a tidy home each day. This was a complex job, and Majic Air got it done."

"I appreciated being able to speak with someone in the office to explain my situation (leaking water heater), and having someone come to my home so quickly to go over my options for dealing with the problem. Dylan, Aaron and the entire crew were so professional and knowledgeable about the on-demand hot water system we chose to install. They were a pleasure to work with, and I would highly recommend them to friends in need of similar services."

"Very efficient and thorough installing a new gas water heater and communicating procedure. Fairly priced also in a timely manner."
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.
