"From start to finish a great experience! Called with no air conditioning yesterday, a Friday holiday weekend. The lady that answered the worked wonders and found tech close by that could come the next morning. I received a call the tech was going to be earlier than expected. Great news on a hot day with no air. The service was efficient and fair priced. Within a hour my unit was up and running again. The sales office followed up right after to schedule a time to look a future options since my unit is getting up there in age. No pushy sales. Professional, quality service. I will use them in the future and highly recommend this company."

"Fantastic! We had hired a handyman from SMAP ( send me a pro ) to install a new bathroom door for us and he did such a terrible job that the door would not even close. Hg came out and corrected the situation so we now have a perfectly functioning door. We now know who to recommend , and who not to recommend, when work needs to be done."

FAQs for air conditioning projects in Catawba, SC

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.
