"Dean's Heating and Air Conditioning have been great since the first call I received back from Lisa. They are very customer focused!! Mike and his team did an excellent job and went above and beyond to replace our duct system that had rusted and collapsed. This was not an easy job b/c our duct work is under the house in a crawl space. ]hey took the time to assess the space and our problems and designed a system that works better than what was there before. They were very professional and Mike explained things every step of the way. If you want someone who is thorough, pays attention to detail and customizes a solution that works for your specific needs, I would highly recommend Deans Heating & Air Conditioning! They did a great job!"

"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."

FAQs for air conditioning projects in Hanover, 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.
