"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."

"I contacted Bluestar Air Mechanical for a second opinion after an appointment with Air One. I have a Carrier HVAC system, and the Air One technician recommended a complete system replacement, claiming the blower was bad, the furnace control board needed replacing, and that there were other issues. Since replacing the HVAC is a big investment, I wanted to get a second opinion. It was only after comparing the service from Bluestar that I realized Air One may have been pushing for a new system sale or lacked the expertise to properly diagnose and repair the actual problems. Isaac, the technician from Bluestar, spent about an hour thoroughly diagnosing and fixing the issues. He found burnt wiring in the furnace and discovered that the wrong capacitor had been incorrectly installed in the AC. Isaac replaced the burnt wiring in the furnace and the capacitor in the AC. After these repairs, my Carrier system was back up and running—without the need for a costly replacement. Bluestar, and Isaac in particular, demonstrated professionalism, expertise, and honesty. They focused on resolving the actual issues instead of pushing for an unnecessary system replacement. I highly recommend Bluestar for their reliable service and Isaac’s thorough and knowledgeable work."

"We had them Replaced furnace and air conditioning unit. It was installed about a year ago but they came out for a regular service about a month ago. the service was free, part of the contract. I have no complaints, it was all good. They were responsive. they were punctual. I have no problems, it was a good deal when I bought it, it's a good deal now. I don't have any issues with how the service went. i bought it through them and I have no regrets and everything was the same as I felt when I bought it. It was a good deal, I made the right choice. Anytime you buy a major system and it doesn't go right you have a problem. I'm a happy camper.1 worker took less than an hour to complete."

"The technician arrived sooner than I expected. That was a great plus. He quickly diagnosed the problem and promptly fixed it. I asked about installing a Air Scrubber. He had one in his van. I had him install it. Tech was friendly and very knowledgeable. Great work."

"Our AC broke at the worst time: Memorial Day weekend. We called several emergency repair companies before Dominion Services, but none of their emergency technicians got back to us. We waited for over twelve hours in our hot home for someone to call us back. Finally, we used Home Advisor to contact Dominion Services Heating & Air. We immediately got a call from the company to confirm our appointment! The technician (Tarone?) was at our house within an hour and had the problem fixed in 30 minutes. I could have cried I was so relieved. Excellent service. We will definitely be using them for all of our future HVAC maintenance and services!"

"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 Occoquan, 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.
