"Coast to Coast Heating and Air has, by far, the most professional team of experts that made the whole process comfortable and easy to understand. We had a total of 8 different companies over a 10 day period that provided us with estimates on several brands of heat pump air conditioners, including Trane, Carrier, Daiken, Lennox, Rheem, Bosch, and Tempstar. Kamil, at Coast to Coast was our last estimate that we received. When they arrived at our home, they did an extensive analysis of our current system including our ductwork, and when they were completed they took about a half hour to write up details about what was recommended. It was the most detail-oriented document that we received out of all estimates. That alone is what set them apart from all their competitors. It is what made us feel the most comfortable with choosing them to do our install. Hats off to their installers, Nico, Anthony, and James for their outstanding, professional installation that was done. They arrived at our home very early in the morning and completed everything ( Heat Pump/Air Handler replacement, and ductwork mods ) that day. They also did a great job cleaning up when the job was finished. This was the most professional install for anything I have ever witnessed. We also need to mention the back office support of this company is outstanding. Faith is taking care of registering the system for us, and also is taking care of the Duke Energy rebate for us, which is very helpful. Coast to Coast Heating and Air is top-notch and highly recommended!"

"I called on Sunday as we woke up to a non working AC. I called a few companies and Coast to Coast was the one who called me back. Alyssa kindly worked us in on their schedule and Carlos was very professional and fixed our air. Thank you so much for returning our call and fixing the air. Will definitely use your services for our AC again!"

"They installed a new system for me. David and Mike were very hard working young men. Answered all my questions and got me cooling good again."
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.
