"Frank has been great. He came over to give us a quote on a fuel tank, and we wound up working with him on several other projects (including an air conditioning install). His guys did a great job, and Frank was a terrific communicator throughout. There were delays, but everything was well communicated and the important things were taken care of immediately. 10/10 would recommend!"

"We recently moved into a house built in 1987 with the original air conditioning unit, which constantly ran without stopping.  It was a brutal summer, but it was definitely not running properly.  Joe came out himself to take a look.  He took a look at the entire system and suggested that we service the AC to make it function properly and not constantly run.  He also changed the air filter in the furnace.  I appreciated the fact that he did not push a new air conditioning system in the house considering the unit we have is 25+ years old.  He also gave us a few ideas on how to make our home more energy efficient.  He did a great job.

"Dave did a great job, he explained what caused our Heat pump to stop working. We bought this unit last June 2019 . So we were very upset when the unit stopped working, it was so hot and Dave had to go up into our attic / crawl space. That was super hot, but he was able to find the problem and get our unit to work. We are very thankful for having Dave as our technician. Thank you Dave and Rohrer's One Hour Heating and Air Conditioning. We have been with them for 35 years."

"I thought they were on the high side. The only problem that I've had with their delivery is, they brought oil when I didn't think I needed it. If I have a full tank in April, I don't them to come out until the fall. I don't have to be here when they deliver the oil, they show up on the day. I don't have an appointment."

"The duct cleaning work was not directly done by signature guys as they dont do that kind of work. But it was nice of them to recommend to another person - John Bonella who did the work for us. Pretty good work -- on time, attention to detail and transparent in the cost estimates. Did quote me on the cost which includes all the vents of the home unlike others who charge based on number of vents etc.. Will recommend him."

FAQs for air conditioning projects in Marcus Hook, 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.
