"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."

"I highly recommend engaging Raynor Services for your heating/air conditioning needs. Our technician, Matt, was very friendly, courteous and efficiently diagnosed and planned the remediation of our heating problem. He took the time to point out what was wrong and provided some extra measures we could take, should we decide to, in the future. No sales pitch, no pressure to add additional costs. Extremely satisfied with Raynor’s friendly service, quick response (less than 1.5 hrs from my call) and low costs to return our heating system back in working order. We will continue to call on Raynor Sevices for all of our heating & ac needs."

"Wonderful. Dave kindly walked me through the reset process on the phone and did not need to come out to service the water heater. I will be calling him in the future for any needed repairs."

"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."

"My central air quit during a nasty heat wave and they responded quicklyâ within a few hours a technician arrived that evening, followed shortly by the salesman when I decided to replace instead of repair. The job was scheduled for the very next morning! The installers were on time, friendly and cleaned up the areas. Everyone I dealt with was knowledgeable and professional. Interest-free financing was a huge selling point. Very good experience!."

FAQs for air conditioning projects in Lebanon, 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.
