"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.

I would recommend premier heating and air with no reservation! Thank- you so much!"

Customers say: Terrific value
"My central A/C failed during this heat wave. After numerous calls to companies having to leave messages, not answering the phone, having to wait two weeks for service or companies not taking new customers, I finally found Rodney owner of RJP HVAC. He answered the phone himself, and told me he could be at my house in two hours! I received a text when he was on his way and promptly arrived. He quickly diagnosed the problem, explained what he could do to fix it and gave me a price which was surprisingly reasonable. I gave him the go ahead and he fixed the issue within the hour. He is very friendly and professional. I highly recommend him and will call him for all my HVAC needs going forward."

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.
