"AMJ Air did an excellent job with my AC repair. The technician arrived on time, quickly diagnosed the issue, and explained everything in a clear and honest way. The repair was completed the same day, and my system has been running perfectly since. Professional, knowledgeable, and easy to work with—I highly recommend AMJ Air for any HVAC needs."

"This was for semiannual maintenance under contract. Danny performed an excellent job, he has many years of experience. I have used ARS for the heating/air conditioning maintenance for about 35 years. They replaced the equipment about six years ago. It has not failed since replacement."

"Dominion Services replaced my 30-year old HVAC system (the outside compressor, and the inside air handler) with a modern one having a 50% increased efficiency rating. The quality of their work is high (four friendly employees with more than 100+ years' combined experience were involved) and have good flexibility to adjust to my work schedule. They easily adapted the new system to the existing hook-ups, and were flexible in their selection among alternate, reliable replacement HVAC systems. The replacement cost was well within the range of the national average. I recommend contacting Dominion Services for insight into any HVAC issue."

"Let's start out by asking:  Would I recommend Ouellette or use them again, ABSOLUTELY!!
(Our upstairs A/C unit stopped working and from a previous HVAC company we received an extremely high quote.  We knew we were on borrowed time for our downstairs unit too). 
We were give the name and number to Ouellette HVAC by good friends of ours.  I was unsure if they would come two counties up to where we live, but they were able to fit us in.  Which worked out to be a bonus for us.  :)   The receptionist who answered the phone was polite and when she said she would return our call...she actually did !!  No tracking anyone down, or waiting for them to call back.  
Devon came out to inspect our A/C unit which was not working.  He was on time, very polite and extremely thorough.  He worked up the numbers and explained in detail what needed to be done with the upstairs unit and why were were having airflow issues upstairs.  (I don't think we've ever felt the air in the master bedroom since we bought the house 4 years ago).  Anyway, the upstairs furnace had to be turned so the new coil (A/C) unit would properly fit.  
Since we knew we were on borrowed time with the downstairs unit we opted to get a quote for both.  After looking at the the unit, we knew found out we needed new furnace too.  In any event, the price, for all three things came in just over what the previously company gave us for one A/C unit upstairs!  And that would not have included fixing/adjusting the venting issues for the lack of airflow.  
One of the things I particularly liked was that I did not feel like I was being talked down to because I was a woman.  I felt that I was spoken to as anyone homeowner should be spoken to, male or female.  
Devon came out for the installation with two others and within two days everything was up and running.  I can honestly say we can actually feel the airflow in the master bedroom (we thought we could not because the room was over the garage...come to find out it was just airflow issues!!)  
Would I recommend Ouellette or use them again, in a heartbeat and without any hesitation!

"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 Stafford, 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.
