"Grove did a great job in presenting all options for our new AC system and potential air cleaning systems (without making any aggressive sales pitches), and then did a great job with installing the new system. The new system has been in place for a few weeks now and is working very well - great job by Grove."

"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."

"Professional, diligent, excellent communications and attention to detail, It's hard to find tradesmen who you can have confidence in, But Edwin has it all. We contracted Edwin's HVAC to replace our 22 year old AC system, he provided a very prompt quotation, with two other company's in the bidding one never responded the other took a week, Work was carried out 3 days after awarding the works, Edwin arrived at the door on time and without delay proceeded to remove the existing system 7hrs later the new system was in, commissioned and handed over carried out in a very professional and excellent workmanship. Ah! I didn't mention price... Edwin's quote was 2/3's that of the competitor and didn't suggest or recommend additional un-necessary work(s) Would I hire Edwin's HVAC again - Yes without a doubt..."

"My experience was fine. I went with this company instead of another company because of the reviews I read on Angie's List. It took them about a half a day to install the air conditioning unit. I think it was 3 workers that came out."

"They did a great job, it is part of a warranty that I have with them. When this condo, they were the HVAC that put the air conditioning, ducts and all of that in this building, they were the ones. They have this wide window where you have got to stay in your place from 8 to 12 or 12 to 5. They did a nice job."

"Moises, the company owner, is incredible. I called 5 HVAC companies to get quotes for full system replacement, and MSR was not only the most responsive, but he came out the very next day. He gave me an incredibly competitive and fair quote for my project, and we immediately gave him our business. Unfortunately, our AC died before he could do the work, but he came out to our house at 6pm on a Friday to drop off a portable AC unit so we wouldn't sweat all night long. We thought we'd be stuck without central air for a few days, but Moises came and worked 9 hours on a Saturday to replace both our furnace and our AC unit. Afterwards, he even gave us a great price on a yearly HVAC maintenance plan. MSR is run by an honest, hard-working tradesman who understands what customers want and need. I won't hesitate to recommend him to friends or to anyone who needs HVAC work done."

FAQs for air conditioning projects in Upper Marlboro, MD

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.
