We had to reschedule install at last minute due to a medical emergency. Aaron was great with the least minute. Definitely my HVAC guy."

"We couldn’t leave a higher review for Prime Home! They are exceptionally kind, efficient, knowledgeable people who do honest & solid work. They have done so much for us this year, all at a reasonable cost & in a quick timeframe. This summer our AC broke and they came out & replaced it within days, while other HVAC companies couldn’t come out for weeks, and at a higher cost. All of their employees are courteous & respectful while performing their job and are never in a rush to get their job done. We are super impressed by their communication, care in their craft, and exceptional hospitality as a business. We will always use Prime Home for all of our HVAC needs!"

"I hired NS JOHNSON to install a Climate Master Tranquility 30 geothermal heating and air conditioning system. Their work was very professionally done, and spot on the budget. The installation took a day an a half. The outdoor temperature was in the low 30 degree (f). On completion of the first day they activated the system to assure we had heat for the night. They completed the installation the next day. Iâ  m very impressed with their work and would recommend them to anyone needing this service. They will continue to maintain the system on a yearly basis. I plan on using them for other services."

"Tash has done a great job! When I bought my house A/C unit stopped working. I searched for a local heating and air conditioner team. He was available same day, came out to check my unit and gave me reasonable quote for entire high efficiency furnace and A/C unit. I can say that he is well educated and knew what he was doing. Unit was ordered and installed with no issue. I highly recommend ATD Tech for Heating and air conditioning needs."

FAQs for air conditioning projects in Harrisburg, 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.
