"I have used Speer Air for several years for HVAC preventive maintenance at my home. We recently expanded and they installed a package unit to take care of the expansion space. The work was good and they have been back for adjustments as necessary."

"Advanced Professionals was very prompt in sending someone over to our office to assess the issues with our Air Conditioning unit. It was extremely hot weather and having an office full of doctors and staff was unnerving and frustrating. They were able to accommodate us right away and sent over their technician Rabi. He was very knowable and extremely helpful in resolving the issue. He was able to get us back up and running. He was very thorough and took his time to explain exactly what the issue was and gave recommendations on how to avoid this problem in the future. We are very confident in the service provided and will continue to use Advanced Professionals for any future services needed."

"This time the owner Bill Ryan showed up with his guy. Under Bill’s instructions, they carefully examined the issue and showed lots of patience to try out different repair strategies. Although the problem is not completely fixed yet, the condition has been improved significantly. Bill showed genuine courtesy and respect to our home and keep following up the situation after leaving. As they promised while making the appointment, the re-visit was free."

"I can't say enough great things about J & M Cooling and Heating! The installation of my new central air system was an outstanding experience. A special thank-you to Dan, the supervisor, who made sure everything went smoothly from start to finish. He was professional, knowledgeable, patient, and took the time to answer all of my questions. It was clear that he genuinely cared about making sure the installation was done right and that I was completely satisfied. I also want to recognize the incredible installation team. They spent days working in an extremely hot attic installing my new system, and despite the challenging conditions, they never once complained. They worked tirelessly, stayed professional, and remained courteous and respectful the entire time. Their work ethic, positive attitude, and attention to detail were truly impressive. They treated my home with great care and left everything clean when the job was finished. My new central air system is running perfectly, and I"

"Our sales rep Matt was great. He explained everything in great detail, Install was fast, next day in fact. Work was done in about 6 hours. They kept the area clean. Purchased both heating unit and AC unit. The price was a little on the high side of the average."

"Woke up to find my basement flooded by broken water heater. Called Pipe Works on recommendation of relative who had used their services. Receptionist (not a machine!)answered promptly, asked if I knew how to turn the water off, and said someone would call right away. Serviceman called me back within 15 minutes and told me he would be there that day. (This was a Saturday). He arrived on time, assessed the problem, and advised me he would call later with an estimate, and description of the work, which he did. The only disappointment was that the water heater needed was not in stock, so had to be ordered and could not be installed until Tuesday. A crew arrived early on Tuesday and installed the heater and cleaned up well. I had some questions about the heater, called their main number during the installation and was quickly connected to the owner, Paul Giglio, who answered all my questions in a friendly and knowledgeable manner. I would definitely recommend this company.

"The technician was very professional and was able to answer many of my questions about the condition of my HVAC system that I inherited and its probable lifetime. I sensed that he was being honest and straightforward. Rather than accept his extensive list of possible replacement parts, I opted to have him install the one that he believed to be the most urgent- the capacitor. So far the unit seems to be functioning well."

FAQs for air conditioning projects in Stanhope, NJ

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.
