"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."

"I have used Scott at AC&H for at least 4 different projects. He has been honest, accommodating, and capable in all scenarios. Scott is the owner and the sole technician and it shows. You can't beat the quality of service that is provided by the owner of a small company. He is very fair in pricing and completely trustworthy."

"Mason contacted me with an hour of my inquiry on line. That impressed me to start with. Donald Mason is very professional and personable and very knowledgeable. Plus he did not make fun of my previous attempts to handle my problem on my own. Very nice man. When he left my home after fixing my problem I had heat in my kitchen for the first time in two years. I even dried my freshly washed sneakers by the heater in the laundry room. I really value this man highly. He was just such a nice person and I will definitely recommend Mason Air Heating & Air Conditioning and Home Advisor to everyone."

"I thought my thermostat needed replacement because it had a blank screen and had stopped working. After contacting Slade through Angie’s List, he called to set up an appointment and was able to come the same day of contact. I was very happy about that because it was very hot, as usual, when your air goes out. Slade was very punctual even though he had to travel during rush hour to make the appointment and was very professional and courteous. He tried various technical methods to isolate the problem and was determined to find the source as he explained every step of the way of what he was doing to my husband. In the process of locating the cause of the stoppage, he dismantled the heat pump, located and repaired the problem, and made preventive recommendations for future use. I also asked about the condition of my heat pump since it’s at least 20 years old and although he said it was still doing good, he said there were newer models that would perform better than the unit we currently have. I do intend to use Slade again before the end of the year to replace my current heat pump."

FAQs for air conditioning projects in Chambersburg, PA

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.
