"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 reached out to Angi’s to find a HVAC company to help with my AC that was blowing hot air in the summer. I got super lucky when I found MSR Heating and Cooling. They arrived on time and assessed my situation. I appreciated the time they took to explain the issue in ways I understood as well as recommend the best option for me. The estimate quote was fair and there were no surprise expenses to repair my unit. I can’t thank the owner, Moises enough for a job well done. His professionalism, knowledge and skills are reflected in the quality of work performed. I would highly recommend this company for your next repair."

"Forage Mechanical did a great job replacing our broken AC unit. Henry diagnosed the problem quickly (broken compressor) and offered some options that would fix the unit and retain warranty protection. He exhibited experience and competence. There were no special costs or fees, and he gave excellent focus to the job, completing ahead of schedule. I definitely recommend this company for your HVAC needs."

"Relieved - that's how I would describe working with Carroll Mechanical. Ever since another company installed my furnace 6 years ago, I don't think it was ever working right. A number of companies have come over the years but nobody was able to properly diagnose the problem until Drew from Carroll Mechanical showed up. He was wonderful from the start and had over 50 years of experience in the trade. He spent the whole morning at my house running a full diagnostic, including a detailed combustion analysis plus measurement of gas pressures, duct air pressures, air temperatures, electrical readings etc.... he explained them all to me patiently like a good doctor and told me we what we needed to do - adjust supply gas pressures and increase the size of the exhaust flue to get the right air/fuel balance. Previous companies just wanted to get in and get out, but these guys took their jobs seriously and were just lovely to deal with. Insanely smart, caring, and reasonable people."

"Air conditioning stopped working. They were quick, courteous and reasonably priced. The technician explained to me what we was going to do and how he would determine what the issue was. I will use them again if the need arises."

"

we had a leak problem and the tech came and looked over our equipment, fixed the problem and left. It cost us nothing and we have had their home heating service contracts for over 20 years.  They have NEVER ONCE not shown up or not helped and in the two furnace emergencies we had--they were here with in 1hr. 

We are very happy.

FAQs for air conditioning projects in Mount Rainier, 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.
