"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 couldn't be happier with the service I received from McCrea Heating and Air Conditioning Services of Maryland. Upon returning from vacation on a 100 degree July day, I found my old HVAC system basically dead (90 degrees in my kitchen!) ... Shane immediately came out to provide an estimate, we signed a contract on the spot, and he kindly provided some freon to hold me over until the new system could be installed. Brian and Nick showed up exactly on time to install the unit, used drop cloths to protect my flooring, and were exceedingly polite and professional throughout. I'd highly recommend this organization."

"I am happy to write this review about JDL HVAC Services LLC. From start to finish; Amber, who setup my initial appointment was very nice & professional. Ire, the technical associate was prompt, very knowledgeable and got my system working again with a temporary fix. I opted for a new heating unit (which was reasonably priced) and all of the technical associates were easy-going and very professional. They were organized, used protective foot coverings and protective coverings for my floors, and cleaned up after the job. Special thanks to the entire team led by Armando; Jerel, Fernando, Michael, & Conrad. NOW, thanks to JDL HVAC, I FINALLY have a properly installed & functioning heating/air conditioning unit. I highly recommend this company!"

"Misunderstanding between Blue Dot and Baltimore County on the inspection.The unit was not installed according to Baltimore county code. Inspection has failed twice. Unit needs to be 3 feet from connection box. They have come out a couple times since the inspection has failed but the issue has not be resolved. It was clearly explained by Baltimore county what needed to be done. I always initiate the calls with them regarding this issue. I did not feel as if they are taking my situation seriously and I would not work them again. I was not advised I was being charged $75 to pay Baltimore County to inspect the Air Condition install. Promised by Jeff, supposedly, a manager a Rep would be at my house in 20 minutes on 12/17/19, no one showed. Jeff acted confused wanted to take a photo so he could figure out what needed to be done to move an Air Conditioning unit 3 ft from connector. Company trades under Blue Dot HVAC. Richard was very friendly and helpful with accommodating the codes for the County."

I found him to be the consummate professional, a person of integrity, transparent, responsive to my questions and willing to work with me to gain my business. I highly recommend Carroll Mechanical."

"Mr. Bonhom (Mike) showed up on time and jumped right on the job. He explained that I didn’t have the issue I thought I had and did a thorough check on both my heating and A/C systems and told me when I should change my filters. His service call fee was great! I highly recommend 3M Mechanical!!"

FAQs for air conditioning projects in Riva, 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.
