"My technician, Lily, was right on time. It was her first time to my home and she was very friendly and informative. She explained what went wrong and also showed me how to maintain some things through my routine maintenance. My service call involved a charge as it was Service, labor plus Freon to be added to my unit and the outside unit's battery. Since I have a contract with McCrea, I was not charged for the part that was to be replaced on my unit. My house is slowly cooling down as it was 90 degrees inside my home when she arrived this morning. My house lost the air conditioning on the Fourth of July and on a very hot day. I would highly recommend McCrea Heating and Air Conditioning Services of PA."

"Adam was so helpful explaining how the ductless heater/ac unit would fit in my sunroom. His three workers were great. Cleaned up the area after they finished, the job was done in about 4 hours. Got three estimates and Weather Masters was the lowest and could install the next day. I also decided to sign a contract for seasonal checkups on my furnace and central air conditioner. I think anyone would feel comfortable hiring them."

We are a small family owned Heating, Ventilation, and Air Conditioning (HVAC) company located in Sharpsburg, MD. The business was started in 1989 under the name of RW Harrell's Pump Service Inc. when Diane Harrell and Ronnie Harrell purchased a well pump and water system business from a gentleman that was retiring. Ronnie had worked in the HVAC field from the time he had graduated from high school so it was natural to add HVAC to the services that this new company would offer. Ronnie and Diane built the company by word of mouth and continue to grow the company in this manner. Additional DBA - Harrell's Services. Additional fax - 928-492-8004

"It was an all-around good service & project. I had a large out-building that used to have electric to it. I wanted to add electric to the building in hopes that if I had to sell, then electric to the building would increase the sale-ability of the property. It was an extensive project. They had to dig a trench from the house to the bldg, add a panel box, run wiring through the 36'x36' 2-story salt-box style bldg, provided light fixtures, outlets, etc... a few days after the project was completed, a large rainstorm washed out some of the trenching. They came out within a day or 2 after the storm & filled back in the collapsed trenching."

"We ended up totally replacing our heating and air-conditioning unit and everything we have done in the house has been through ET Lawson and under a warranty plan through them. We wanted the same thing. Nothing against Michael & Son. He seemed very knowable."

"After I was scheduled for the next day, the owner of the company contacted me to reschedule for the same day. I got three technicians out to check out my system, which needed an air filter change. Filter change complete, they tested the pressure of my system which checked out well. All it cost was for a service call. Great response and service."

FAQs for air conditioning projects in Sharpsburg, 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.
