"Overall, the project went very well. They did push our initial installation date back by 3 weeks but once here, they put in the hours to get it done in a timely manner. I especially appreciated the professionalism of Keith, Pedro C and Kody M. They put in 2 new units with new duct work to fix the balance issues that we were having in our 3200 sq ft home. Now, the temperature in our home is consistent in the various rooms which has been a problem over the past 20 years. Keith said that the project was underbid by error but they stuck to the quote that was given to us. We had several men from the company working on the project. By far, Pedro C and Kody M stood out and were top notch paying attention to detail and cleaning up after themselves on a daily basis. It was very hot and they stayed late to make sure that we had air conditioning over the weekend. The bottom line is that they did not cut corners and were neat and professional and most importantly delivered on their promise to give us a system that works well. I have already recommended them to 2 of my friends/family."

"Felipe and his crew did a relatively large project for me to repair a 120 sq ft cottage that sits at the top of the hill in my backyard. Originally there were trees running through the cottage and surrounding deck, but the trees had to be removed. Felipe patched the hole in, and replaced the shingles on, the roof; replaced the ceiling wood planks and installed new flooring inside the cottage; replaced the surrounding deck; designed and built new stairs going up the hill; and reinforced the support for the whole structure. Also installed a mini split (combination air conditioner/ heat pump). Workmanship was outstanding, lots of attention to detail. The crew arrived promptly at the stated time and were very polite. Once started, they worked without interruption until the project was complete (~2 weeks). Very thorough clean-up. Communication with Felipe was excellent. VERY HIGHLY RECOMMEND!!!"

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.
