"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."

"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."

"I received six estimates for replacing my air conditioning system. Of the six, four came in at a reasonable price including the estimate from the Michael Bonsby Company. Three of the four estimators made a good impression but the one who impressed me the most was David Lux of Michael Bonsby. He spent the most time, provided the most information, and fully answered all of my questions in all of my contacts with him prior to signing the contract. Even after I signed the contract, had the system installed, and made final payment, David Lux was still very prompt in answering my inquiries. So far I am very happy with the air conditioning system installed by and I would highly recommend the Michael Bonsby Company if you ever need to replace your air conditioning system."

"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."

FAQs for air conditioning projects in Cheltenham, 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.
