"We were Extremely Satisfied with the Quality of Workmanship and the Product we Decided to go with for HVAC Install... At the same time we had Central Air added, we were tired of window units... Plus, it is Less Expensive to have Both Installed Together!! We Have Really Noticed a Big Difference in how the Rooms in the House are Much More Evenly Heated and How Much More the Heat is Felt while Moving from Room to Room, From Floor to Ceiling!!! The House Has Never Felt So Good!!! A 10+ Star Rating in Our View from the Install and Service from Connelly Heating Air Conditioning!!! In Addition, We Saved over $1,000. with Connelly Heating Air with Bids from 3 other Companies!!! Thank You, Jean Tony S. in Manheim, PA."

"

Not only did they put in a new furnace, but the ducting that was in here at the house was, like 30 years old so they tore it out and re-did it with custom ducting made out of these big sheets of metal. They only charged me $3,000 for the furnace. I am glad I did because it has made a huge difference in the air quality here.

"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."

"Steve assembled a trampoline for me in about 3 hours on a Friday morning. He was kind, knowledgeable, and communicative throughout the whole process. He broke a bolt during installation and drove to the local hardware store to replace it. He also hauled all the trash away for a small, reasonable extra fee that was negotiated in the spot. Zero complaints. Just good work. Steve will be the first person I call for assistance with other jobs from now on for sure. Thank you!"

FAQs for air conditioning projects in Conestoga, 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.
