"Our air conditioning was not working and our house was extremely hot. I called on a Sunday afternoon and Matt came later in the afternoon and fixed our problem. Our air-conditioning is working again and we will finally be able to have a good night sleep. I was thrilled that Matt came out on a Sunday evening and fixed our problem. He also took the time to show me how to change the filters in our unit and had me practice to make sure that I could do it by myself. I would highly recommend Conde Tech Services."

"The technician (Shammion) arrived on time and spent time listening to my concerns and answered my questions before proceeding with the work. Shammion has serviced my furnace and a/c unit previously, and on each occasion he has spent time informing me how various parts of my HVAC should work and what I need to do to get the most from the systems. On this occasion, Shammion instructed me on how to use my new thermostat and how best to keep my condenser coil clean in the future. The work was done expertly and in a professional manner, and I highly recommend Shammion and McCrea Heating and Air Conditioning."

"I recently had SwiftPro conduct an inspection and assessment of my HVAC system, and am very satisfied with the service. Tyler and Moises were highly professional from start to finish, wearing boot covers to respect my home, and thoroughly explaining their findings. They were efficient, courteous, and took care to ensure everything was done to a high standard. I will likely be using them to replace my entire furnace and air conditioning unit. I highly recommend SwiftPro for anyone in need of trustworthy and quality HVAC services!"

"Company called instantly upon getting Service Magic request for emergency service and tech arrived an hour later. Tech helpful, professional, fast working. Another company previously said I had a faulty gas valve and would have to replace furnace because parts not available for 30+ year old furnace. However, Consumer's Choice tech said valve fine; just cleaned out pilot light and I had heat again at low cost. Also gave estimate on smaller (more suitably sized), more efficient furnace if I did need to replace because heat exchanger is rusting out. Will definitely consider them for future service or install. Very satisfied with this experience."

"Terrone responded immediately to our request for service on Saturday. He came to service our air-conditioner which was working minimally. He did fix it and it gave us relief from the heat. However, we knew that our heat pump/air conditioner was in need of replacement. Terrone talked to us about options, gave us some time to do research on the best choice for our home and came back to do the installation. His pricing was reasonable. He and Caleb worked to removed the old system, install the new system, install our new Smart Thermostat ( I-Comfort) and come back to check on the system and us that everything was working correctly. What makes our experience with Mr. Terrone Street so satisfying, both from a professional standpoint of excellent service but also and equally important from a personal standpoint, is that Mr. Street is is a man of integrity, character and dedication. He is honest and attentive, working always to do his very best for his customer as he would want for himself or his family member. He will do his best for you too, with commitment, capability, positivity and honesty."

"The team was very helpful with identifying the issue with our heating system and providing guidance on how to proceed. We replaced the entire system (which was 10 years old). Very happy with the end result. The air is so much cleaner and my son's allergies have significantly reduced."

"T&J Service installed a beautiful new Trane system at my home in Fairfax on May 14, 2024. They were recommended to me by my neighbor who has been using them for many years. Without a doubt, Diep and Tran are the most highly-skilled HVAC professionals that I have encountered in over 40 years. This was a very large, complex system to install and they got it done in one day. These are some of the hardest working, most dedicated guys that I've ever seen! I absolutely love my new Trane system. They even custom made a beautiful plenum for my air handler --handcrafted out of stainless steel (Diep is also a skilled metal craftsman). 5 STARS"

FAQs for air conditioning projects in Dumfries, VA

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.
