"I cannot speak highly enough of David and his team. When I got a moderately high radon reading on the home I was selling, I had to take care of it quickly so that my closing could go through. David worked me into his schedule and came to my home the day I called. He was delightful, did a thorough inspection, and gave me an estimate. I subsequently got an estimate from another vender, and it was $1,000 more! Not only that, but David had figured out a way to perform the remediation without installing unsightly pipes either on the inside or outside of the house. This involved him working in a very shallow attic space to run the pipes up through the heating ducts, but he was happy to go the extra mile. On the day of the work, David and his wonderful assistant Ryan arrived on time, and spent the better part of a day installing the system. They were convivial and professional without being the least bit instrusive - I enjoyed the experience! After the installation, David explained it to me in detail, and left a radon kit so that my buyers could check the new levels. Not suprisingly, my buyers are more than happy with the results. If you need to have this job done, call David. You won't regret it!

"I joined Angie's List to find someone that worked on portable air conditioners. My brother took the unit apart to get to the blower wheel - but he told me that he didn't think that he could get to the damaged part and even if he did, he wasn't sure he could put the unit back together. My brother can fix anything, so when he gave up, I knew that I needed a professional. I liked the reports posted for "On Call Maintenance", so I called (on a Saturday) & left a brief message about what I needed. In a very short time, Steve returned my call & he told me he felt confident that he could replace the part & put the unit back together. I ordered the blower wheel & received it on the following Wednesday. I called Steve & made an appointment for the next day at 10AM. Steve had the part replaced and the unit working within an hour. He was professional, courteous, punctual, & returned/answered all of my calls. My unit works great & Steve even installed the hoses & weatherized the windows better than they were before. I will definitely call on Steve in the future. In fact, I have a plumbing problem in my kitchen - I think I'll call him now."
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.
