"I was really worried I would have to go a few days or even a week without cool air, but I called Dayco Systems that my friend recommended and I'm SO glad I did! They came out right away, after hours and fixed the unit. I highly recommend this company!"

"I selected having my new HVAC (heatpump) system installed by Ragsdale based on the qualified sales consultation, the use of Carrier products made in the USA, and Ragsdale being a local certified family run business. My new unit was installed this morning by two technicians who worked efficiently and who kept me in the loop about the new equipment, thermostat, warranty, and FAQs. They were polite, neat & tidy. Well recommended."

"I hired Top Quality to remedy a specific problem I was having that was causing me serious health issues. Although my home is only 3 yrs old I started having breathing issues that was affecting my health. Jeremyâ s crew came out and took care of the obvious problem but upon more research he determined there were other areas in my air system that may cause further issues. The problem was getting to these areas . He told me he was not a miracle worker but he would do his best to solve this issue. All I can say is he and his crew are miracle workers! They took care of a very complex problem that went above and beyond the normal scope of HVAC service. Thank you Jeremy and crew for taking care of this problem! I highly recommend this company! They went above and beyond what I was expecting!"

"Adam and team installed a new HVAC system for me. From start to finish, they were prompt, professional, courteous, efficient. After diagnosing the problem, Adam took the time to explain the issue and lead me through all the potential solutions. Installation went flawlessly. Adam's team did a great job including putting covers over their shoes while in my home and cleaning up after the job was complete. I would definitely recommend 4 Seasons for your HVAC needs."

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.
