"Very pleased with the install of a new furnace and air conditioning system. They showed up on time and they were courteous and professional. I got price quotes from two other companies, John's price was the lowest. I feel as though I got the best equipment and installation, in addition, they provided more system improvements than the other two companies offered. It was a good decision to have chosen John!"

"Shawn was very professional. I was expecting a quick in-and-out service but he spent a lot of time making sure everything was ok. He found a Carbon Monoxide leak in the system, I was there the whole time and he showed me everything he was doing. We are grateful for his professionalism and hard work. I totally recommend this business, and Shawn especially. Great job and thank you Shawn"

"The person who came to the house knew what he was doing. He tested the heat pump and then the thermostat and then went in the attic to test the air handler. He diagnosed the problem and came up with a solution. Excellent service."

"I not only had an old furnace replaced but also had whole house air conditioning added. Very professional family business. Their estimate beat out two other HVAC businesses here in Lompoc⠦⠦ one of them by thousands of dollars. It paid to get three estimates. Daniel was easy to work with and honest. One of the other HVAC businesses in Lompoc is interested in selling you all kinds of stuff that increased his estimate by thousands of dollars. I highly recommend Ace Heating & AC."

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.
