"I did a fair bit of research and spoke with a couple of companies. I also checked with the North Carolina state site on what to expect from a radon mitigation system and what to look for in a company to install a system, in particular to make sure the installer is certified.
Two main reasons I went with Covenant Air. The first is that David Coffey was the only one in my area I could verify was certified in Radon Mitigation and I was certain that the person completing the work was if fact certified. The second reason is that on our initial conversation David was very informative and straight forward, not pushy and wanted to assess our home and the need for a mitigation system prior to giving a quote.
David ran a 3 day test our home with a device prior to any recommendations to determine if a mitigation system was needed. The results indicated that our radon level was between 10 and 16 (I can't remember the unit of measurement). EPA recommend below 4.0 yikes! David installed the system. He was professional, efficient, friendly and he even cleaned up after himself. Not kidding I didn't have to do a thing! He returned after the system had time to do its work and retested. The level were down to 0.7 and at no time higher than 2.0. The system is quiet and out of the way, you don't even know it's there.
David was very flexible in his pricing also, allowing my husband to install the pipe from the pump to the roof to reduce our costs. He told my husband exactly how to complete the work.

"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."

"Scott did an excellent job. He was very professional and even made recommendations on how to improve the quality of air in our home, in addition he took his time and the pricing was very reasonable. I would highly recommend this company to anyone that is looking for air duct cleaning."
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.
