"Everything went extremely well. I found Grove a completely professional organization with highly skilled workers. Their plumber subcontractor handled the installation of all gas piping in my house, oversaw the hookup with BGE's gas line and installed the hot water heater. Grove provided a skilled crew of 5, with 2 working outside and 3 inside to remove all old equipment, do some duct repair and install the new air conditioner, gas furnace, humidifier and thermostat in 2 days. They also removed all debris from the worksite and swept it clean. Their work proposal included a year's maintenance, which I feel sure will be equally satisfactory. This was a big project (3 days including the plumber), but I am confident they would handle both small and large jobs with the same competence and professionalism. I highly recommend them."

"Everything went great. My AC died and it was close to 20 years old so I wanted the whole unit replaced. I have 4 young kids so no AC in the summer was not a pleasant option. The owner came out on site the day we called and was able to have the new unit installed the next day. I have dealt with many HVAC companies in the past as an Insurance Adjuster. These guys exceeded my expectations and were very reasonable on price. I highly recommend using Buric Heating and Air Conditioning!"

"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."

"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."

"Ryan and Mitch came out and spent about 30 minutes checking out the various components of my air handler and heat pump. They scrubbed some rust off of coils and they identified a capacitor that needed to be replaced showing me how the part was showing its wear. They will return in a week to replace it. They were professional and took the time to explain things to me. I will certainly use them again!"

FAQs for air conditioning projects in Crofton, 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.
