"We've had Hendrickson and Son's out to our place for a couple different projects including running a new sewer line to the street. Each time they have been punctual, attentive and have really gone above and beyond. This is one contractor I'd both hire again and have recommended to family needing plumbing work. Very please with John and all his team."

"I highly recommend Thomas with Prolific Mechanical. Another company came out and told me I needed to replace my HVAC system, but I decided to get a second opinion. Thomas took the time to properly diagnose the issue and was able to repair it instead of pushing for a replacement. He saved me a significant amount of money, was honest, knowledgeable, and professional throughout the entire process. If you?re looking for someone you can trust, Prolific Mechanical is the company to call."

"He was very upfront with us and told us exactly how it would go. We just told him to do what he could and he just did what he could. He did fix the problem. He was friendly and professional. As far as I’m concerned plumbers don’t weigh too much, no matter who they are. I think the going rate is $100 an hour or so, and so he charge us the same. He was fine with the appointments and he didn’t damage anything. We had him out here a year ago to remove an old soft water piston. I liked him then and that’s why I called him the second time. He did a good job. He usually comes out as soon as he can. Time before last when he did the water softening, I think it took him a day to get out here. It was the next day after I called. With this last plumbing faucet thing, he was out the same day; in fact within two hours I think. He is very responsive. I don’t think his price is high but I just think plumbers want too much money. The quality is very good. I will use his services again in the future."
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.
