"I have used Relax Air services twice in the past. On November 19th my water heater stopped producing hot water, I've called Nasser to come over to assess what needed to be done. On Monday Nov. 21st he replaced my old water heater (21 years old) Nasser is honest and very reliable. He is very reasonable with his pricing (I have compared Nasser's pricing to my next door neighbors water heater replacement cost). I would highly recommend Relax Air. A huge THANK YOU to Nasser...Relax Air is the ONLY company for my Heating And Air Conditioning needs!"

"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."

"Quickly diagnosed the central air conditioning system, and gave an estimate on the cost of recharging the refrigerant in the compressor. The system is a 14 year old Carrier unit. Albert also included some sealant that may plug up the slow leak of refrigerant that occurs every 2 years or so. Albert also, showed me how to adjust the damper to control the flow of air to the second and third floors of the house. The other company that arrived wanted to charge me $5,000 to repair the system or close to $7,000 to replace the AC system with new. I intend to call upon Magna Tech Temp Air, Inc when I'm ready to purchase a new HVAC system. Thanks again for taking the time to listen to my concerns. Well done!!!"

"Ray was great! We had a heat pump and air exchanger replaced with a 19 seer Carrier unit. Ray was at least $2000 dollars cheaper then any of the other contractors we checked with for the same unit. He came promptly when scheduled and did great work. I would highly recomend R.A.A to anyone who was having HVAC work done on their home. Thanks Ray!"

"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."

"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!"

FAQs for air conditioning projects in Bristow, 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.
