"I would highly recommend Affordable A/C and Jonathan for your A/C needs. They were first to answer my request on a Sunday. Jonathan & his assistant arrived on time Monday morning to install a unit in our attic. They were very professional, efficient & got the job done in a very timely manner. We actually hired them for another job which they completed the following day. Again, I highly recommend Affordable Air Conditioning & Jonathan."

"Hagerman Services has proven to be one of the most reliable and professional HVAC companies that I have done business with. My most recent service was air duct cleaning and I have noticed a tremendous difference in the reduction of dust that settles on my furniture as well as less issues with my allergies. I will continue to use Mike and Hagerman for all my HVAC needs."

"From the initial phone call to the completion of the work, these guys were amazing. I was put at ease explaining my a/c problem with the rep on the phone and was reassured that they would fix the problem, everything will be fine and his guys will be there between 3 & 5pm. Well a storm came through during that window of time & I thought they were not going to make it. I was wrong. The guys showed up right after the stormed cleared. Roderick, diagnosed the problem, low on freon by three gallons and quoted the price for service. Soooo reasonable I let out a sigh of relief. The coils on the a/c were iced so they couldn't complete the freon input that day. Came back the next morning, as promised, at 8:30 sharp, finished their work and we had cool air w/in a hour. They were extremely professional, the guys explained Everything, and they guarantee their work. They have my a/c business from here on out! Thanks again guys!"

"Mr. Chauvin gave us quick service and worked with us to handle paying for the repair to our air conditioner. He gave us a good price and didnâ t try to take advantage of the fact that the A/C was out during the heat of summer."
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.
