"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 had a 20+ year old air conditioning system and didn't want to nurse it through another summer season so I started looking for a replacement during the very polar cold month of February 2019. Of the three bids I received, I was most impressed with Polar Bear Air Conditioning & Heating Inc's responsiveness, professionalism and price. Three days after I signed a contract, Team Polar was at my house at 8:30 am and by 1:00 pm I had a new air conditioning system! The team worked fast, was pleasant, provided updates and handled the one problem encountered, the condenser wouldn't fit through the front door of my old DC townhouse, with grace and humor as they hauled it around the block and in through the back walkway. I'm looking forward to having a cool, reliable and energy efficient system this summer and would definitely recommend Polar Bear Air Conditioning & Heating Inc. to anyone looking for a new system. Thanks again Polar Bear Air Conditioning & Heating Inc!"

"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."

"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."

"On a very hot weekend, I lost my air conditioning and could not reach my regular HVAC contractor. I made contact with I-HVAC first thing Monday morning and they fit me into an extremely busy schedule even though I had not used them before. Sam was a good communicator - explaining everything as he worked, providing tips on what I should be doing. I would recommend them whole-heartedly. They are now my regular contractor!"

"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."

FAQs for air conditioning projects in Mount Vernon, 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.
