"Serg has cleaned my ducts before so when I needed to replace my furnace, I called him, he came the next day and gave me a more than reasonable quote. 2 big box stores were about double and triple his quote for the same unit! They started work early in the morning so that they could finish in 1 day out of consideration for me as I am pregnant with twins and they did not want to leave me without heat in the winter, even for one day. I am so grateful to Panda, they did a great job. I was honest with them on what I needed and wanted, and they did a great job for me. THANK YOU SERG!!"

"The Appliance Guy (Justin) was exactly what we needed. Straight shooting, to the point, knowledgeable and professional. Repaired our 1930s antique Magic Chef that others quoted us insane amounts to get up and running. Justin came in, did a thorough cleaning, located the issue, repaired the pilot light system and got her up and running at a fair price. So pleased with the outcome of his work. Will 100% use again for future appliance needs."

"I wish there were a rating higher than 5...that's how good they were. Alex S. & Dimitri were professional, courteous, timely and explained every step. I used them to clean out the dryer vent, but will also be hiring this company to clean out the air conditioning vents as well."

"They were extremely professional and friendly. Very tolerant of the conditions in the house and that I have 9 cats. They had to comply with my condo regulations, which was time consuming. It was also difficult that the major part of the unit was in the attic. Very tight and HOT!"

"I called when they were swamped during the blazing heat of July, and they couldn't make it out to me for 1 week. They called back 2 days later and fit me in (I did do some begging as I have young children and pets and needed my air back for them), and did the repairs in 1 day! Thank you again so much Serge and Mark!"

"We had our old boiler removed and a new 250,000 BTU Weil-McLain installed. The experience was great. The price was really fair, especially for the quality of work. They showed up right on time, got straight to work, and you could tell they knew exactly what they were doing. Everything was done in a very organized and professional way, but still felt easy and stress-free on our end. What I appreciated most was how clean and quick they were—no mess left behind, and the job was done faster than expected without rushing anything. Overall, just solid, reliable service. Would definitely recommend them to anyone needing boiler work."

"It was a superb experience. From the visit by Bruce the sales representative to the installation day to the follow-up from Petro, every single person we interacted with was helpful and professional. When Bruce arrived to do the assessment, we spent time going over the heating needs in the house. After a thorough inspection and measurement of the house, we sat down. He showed me a few options, all of which were going to provide good service. I ordered a unit at the end of that meeting. The installation day was just terrific- the entire work crew that showed up were everything I would hope to find: Upbeat, informative, hard-working, focused. The job was finished before end of day as promised. The heater room is now immaculate, with new piping and a new heater. It was like watching a pit crew at a NASCAR race. Everyone had their tasks, they moved carefully but quickly. The materials were all laid out in order, etc. Just a totally professional approach to their work. The crew boss answered any questions I had. The follow-up for a normal inspection of the furnace chimney was scheduled the day after the installation. I’ve gotten calls to insure we are satisfied with the work. Satisfied barely covers it- I am pleased to write this kind of review. Without hesitation I will recommend Petro to friends and family throughout the Philly area. Peter A. Elkins Park"

"My windows leaked air and my bedroom blinds needed to be replaced So I bought 2 new ones and also bought 2 kits to seal the windows. I used Angi previously and asked for a quote for a handyman to install and seal, T&S responded and sent a handyman to see what needed to be done. Quote was fair and I agreed. Handyman was able to start immediately and was professional did a great job. I would recommend them highly for any handyman type project."

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.
