"I had a contractor grade furnace that lasted only 11 years and had a leak. My regular jobber gave me a bid but it was very high. I got Aire Serve thru Home Advisors and their bid was almost $4,000 less and the air conditioner was higher SEER, higher tonnage, the furnace had 20k more BTU's and the warranties were much better. They came out in a few days and did the whole installation of both units in 6 hours. WE are pleased!"

"Absolutely amazing!!! Our AC stopped working today, and with the health issues that my kiddo & I have, long wait for an HVAC tech availability was not something that we could risk . We found 717 Home Comfort recommended on one of our local community pages & we were lucky enough that Derek had availability to come out within the hour. Thankfully it was a simple fix. Derek was very transparent from the start with pricing & there were no crazy extra fees. He was very friendly, personable, and professional.. He is now our go to HVAC guy, & I 1000000000% recommend!!"

FAQs for air conditioning projects in Shippensburg, 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.
