"Saturday afternoon and I realized my home was not cool. The thermostat was 83 and climbing. I was able to contact A-Anderson HVAC and electrical. They were at my house in less than an hour and less than an hour later my AC was cooling. Dylan stayed long enough to check the air temperature coming out of the vents. He was very friendly, thorough, knowledgeable . Everyone from phone to personal service was great. The price was also in my expected range. I highly recommend this company."

"Air conditioning stopped working and I went to a couple of neighbors here and both of them have used this company before, so I called them and they came to check and he said that the compressor was not working and they gave us a couple of options to proceed, he thought that he could find another compressor but probably will not be new since next year companies will not sell these units anymore because of the cooling system so then he suggested to replace the entire system. The end result was amazing, this ac unit does not make a sound at all. They actually helped the neighbor and it was free of charge, he asked me to listen to that ac unit and he explained what was wrong with it and he suggested me to give them advice so they could fix their ac system too."

"My new air conditioner is truly a work of art! I obtained several proposals and while most of them were within a few percentage points of each other in terms of cost, I chose Efficient Home Solutions. There were several reasons. First, David took the time to show me the math about my CFM airflow problem. I have been short about 800 CFM all these years and it's probably why my other unit wore out after 12 years. I got a 5 ton Lennox unit and David explained the differences between it and a comparable Trane (which I had previously installed). I think having a local company with access to parts in the future was a great reason to pick Lennox. The unit is a beast. Secondly, David brought his installation manager who carefully inspected my attic space and location of new return ducts. No one else brought theirs. This made a big difference because there would be no question as to what would work space-wise or not. Third, David also answered all my questions professionally and even explained many details I hadn't thought of (nor did any other service provider). I really like my Nest control and this unit cools within 40 seconds, and after 2 minutes, it's freezing! The family room is facing the hot west sun and now we can't even tell it's hot outside. I highly recommend them!"

"I was just getting home from work and I happen to noticed that my house was really hot, the thermostat was reading 85 degrees while set for cool, the blower was working but my air conditioning system would not come on. I stepped outside and walked over to the system and heard a buzzing noise but nothing was working so I went on to my app and requested for an air conditioning company and Young and son stopped by the same day. Julius was able to diagnose the problem I was having with my AC system and explain the buzzing noise, within a short period of time my air conditioning system was working and providing my home with cold air. Thank you!!!!! So much young and son, I am going recommend your services to all of my friends and relatives."

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.
