"All I have to say is that Absolute Comfort Heating and Air Conditioning exceeded our expectations on the installation of our new Trane heat pump! Alex was our point of contact, and he was very knowledgeable, and courteous. The installation crew arrived on schedule and impressed us with their expertise! Robert, Courtland and Cody got right to work and took out the old system… and then installed our new heat pump. They were all knowledgeable, friendly and courteous… answering any questions we had! One day! We have cool air tonight! Thanks guys!"

"Service Tech msg when he was on his way. Arrived on time and was very professional. However, the estimate for the replacement unit was 3 times higher than what a unit should cost to replace. So needless to say, I was disappointed in their quote."

It felt like having a family member working on my system, thats how comfortable, and rest assured I was with the Tech. He explained everything to me and most importantly, the company didnt try to haggle or bankrupt me. I will truly forever "Call Dad" for my electrical work. 10/10 recommend."

"JC was very good about communicating and being responsive both through Angie's list as well as follow-up phone calls and email.  He was very prompt and professional.  He even offered "free" advice/suggestions on how we could fix it ourselves if we wanted to.  Even though we didn't use him for these services to do this job at this time, I would recommend him and give him a good rating based on the other criteria.  Would use in the future if needed.

FAQs for air conditioning projects in Lancaster, 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.
