"I called and they sent someone out the next day. They were prompt and efficient and most of all the swamp cooler was repaired. The price they charged was excellent. I also signed up for a maintenance contract based on how well they took care of this problem. There are not a lot of places left who service swamp coolers so this was a good find. I have already recommended them to my sister for service on the air conditioning system in her home."

"I highly recommend Top Energy Solutions. During the heat wave my air conditioning system blew out hot air. I expected to wait days for a technician to come out. Leor sent one the next morning. The technician quickly located the problem and fixed it within minutes. Their employees are professional, courteous and very knowledgeable."

"RR Electric replaced my AC unit and my furnace and installed an upgraded electric panel. Everyone from the guy who came out to give me the estimate and explain everything in detail, to the team that installed the AC unit and the furnace, to the team that installed the new electric panel, to the team that patched up and painted the stucco, to the guy who came out and tested the system after all the work was completed, to the people in RR Electricâ s office were ALL fantastic. The communication was great. I would highly highly recommend them."

"I highly recommend Belle Air Services! From the first moment I called to get a quote, to the moment they finished the job, I could not have asked for better customer service, top notch work, and competitive pricing. They communicated with me all throughout the process, made sure I understood everything that would be done, were on time, protected my home and were clean. They even worked very well with my HOA (who is very tough!). And to top it off, they didn't try to up-sell me as other HVAC contractors have in the past. So pleased that I have found this HVAC company!!"

"They added an air vent in our house. They did a great job. They did reschedule twice but it was okay since it's a smaller job. They finished the job within the 2 hours window. The technicians were very knowledgeable and were able to explain the process and showed what they done to complete the work which was very great. The air flow within our master bedroom is great now."

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.
