"Cam was awesome! He showed up early (as requested), did a great job assembling my son's crib, cleaned up afterwards, and was so pleasant to deal with. I'd absolutely recommend him to anyone who needs a handyman!"

"Highly recommend this company. Sammy listened to our goals for the project to provide a/c and heat to our large garage allowing my husband to work on his cars throughout the year. Sammy offered several approaches to meet our needs. He provided 3 options with detailed specifications and costs. He answered our questions thoroughly explaining the different systems and what they could and could not do. He and his crew were professional, courteous and took great care to protect our property while doing the installation. When done the area was left neat and clean. We received a thorough explanation and demonstration on how to use the new equipment. We are thrilled with the new system and highly recommend Tabora Air Conditioning and Heating LLC .. Sandra C. Fairfax VA"

"Her did an excellent job for replacing the fan motor in my furnace. He did not try to sell me something I didn't need yet. Gave an honest assessment of my heat pump. Heat pump blower works very well!"

"Mr. Coffee is a hero who risks his health daily to help mitigate dangerous radon problems for strangers who call for help. This is a dangerous job with daily high radon exposure and when I asked, he said he is aware of the risks but gets his health scanned multiple times a year. I called Covenant Air back in December after noticing that my Safety Siren Pro radon detector kept reaching alarm. Mr. Coffee came out and assessed that I could probably fix the problem myself by sealing some obvious cracks, especially around some pipes, and recommended the products so that I can do it cheap DIY. He was obviously not pushy to scare people into signing contracts, but actually tried to dissuade me from hiring him right off on installing sub slab depressurization. Although the DYI route he recommended would've been cheaper, I hired him to performs the job. The sealing did bring the radon level down where my detector's alarm didn't go off, but I wanted to lower it as much as possible. He then recommended a passive ventilation route given my reading. The passive ventilation again slashed the radon level in half, but I wanted the radon level down even further, so I ultimately opted to install the fan after weeks of data collection and analysis. He installed the fan so that I could easily turn it off to save energy based on seasonal variations. He is a very personable and methodical person, and prefers to monitor the progress of his work so that his customers don't hastily incur unnecessary cost. You almost never see someone like that in the service industry, and I cannot recommend him highly enough.

"Ismail explained everything in detailed and was very patient with my repetitive questions. He measured and explained how the system worked. I was very pleased with his service and his committment to replace my system in a timely manner. I would definitely use him again!!! Compared to the other estimates he was very reasonable and worth the money."

"Mike and Crystal were very professional from the first phone contact through the completion of the work. They showed up on time, their work was neat and they worked very efficiently. My windows were in pretty bad shape. They really took their time and prepped them very well which showed in the finished product. When asked to redo or touch up anything it was done without question. In the end we received a very good paint job on a timely basis and at a competitive price. I have already recommended Mike's Painting to others in my neighborhood and would use him again for future painting needs.

"S.E.C Heating and A/C Mechanical Service replaced an Central Air Cleaner. Lowest quote and the best service by far. The master tech and owner was extremely professional, knowledge and friendly. He explained everything to me in detail which I loved."

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.
