"I recently used New Energy Solutions to install a new heat pump, air handler with auxiliary heat, line set, condensate pump, and thermostat. Erik and his team did a great job from the initial estimate through post-installation support. Erik took the time to listen to my needs and questions, and presented a number of appropriate options. During the installation, the team (which included Erik) worked quickly and cleanly, and installed everything properly. When the heat pump began short cycling the following day, Buddy showed up quickly to troubleshoot the issue. When the cause proved quite tricky to diagnose, Erik was able to arrange for Buddy to get support from Trane’s lead technician and trainer for the east coast (on a Saturday, while he was with his family) to help solve the issue then and there. Amazing service from both Trane and New Energy Solutions! When Erik initially asked me what he needed to do to win my business, I told him that I was looking for a quality product that would be backed up by the manufacturer that would be expertly installed to minimize the risk of installation-related issues – all at a reasonable price. I was looking for a product that would work, and no BS from the manufacturer or installer if I ran into issues. So far, I’ve gotten everything I was looking for."

"The rep was very honest. He stated we would need a whole system (water heater, air conditioning system and furnace) which would have cost thousands of dollars. The house is for sale and it wouldn't have been worth investing the money. He even waived the $50.00 estimate charge for checking it out."

"This company is well versed in many types of heating and air conditioning systems and has been maintaining and servicing my businessâ s heating and air conditioning systems as well as my systems in my home for a number of years. The owner is very knowledgeable and happy to explain whatever repairs and or maintenance is needed. His pricing is more than fair - this is not a business man who is looking to gouge his clients as so many service people seems to want to do. Additionally, this company does not keep people waiting for days when they have an emergency! I can highly recommend!"

FAQs for air conditioning projects in Lehigh Valley, 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.
