"Ray's HVAC responded quickly to my request to repair my furnace, which could not start this year. They were able to find and fix the real cause of the issue - a bird net in the PVC pipe which blocked the air flow, and made my furnace is working again!"

"The work consisted of replacement of gas furnace as well as air conditioning unit from early 1990's. SOS's price quote was competitive with two other quotes. I elected SOS specifically due their responsiveness, cooperation, proximity, and rating on Angi's List: 1) owner (Rob S.) came out immediately on a Saturday a couple hours after my call to review job and provided the price quotation within a couple of days, 2) quoted work with different AC manufacturers based on my preferences - did not try to push other units, 3) scheduled work per my calendar request. The crew. lead by Michael W., was very hard working, professional, and dedicated. I was also very impressed that crew performed a separate pre-inspection a week before the installation to familiarize themselves with the scope and work out a few details. Job was completed according to the schedule and quoted price!!! In summary, I'm very happy with the quality of work as well as my decision to select SOS. I highly recommend selecting SOS."

"My husband and I recently purchased a home and realized we had issues with our central air during a heat wave. We received estimates from approximately 5 different companies but we went with Dun Rite for a few different reasons - 1) We worked with Pete from Dun Rite and he was such a nice and respectful human being unlike some of the other companies he was pleasant. the customer service is impeccable. 2) he didn't rush with explaining the issues he found with the system. He truly wanted us to understand. 3) he wasn't trying to overcharge us with items we didn't need unlike some of the other companies we received quotes for. we signed the contract with the quote and contacted our AC warranty company. Dun Rite was going to get paid regardless but we wanted to see if the warranty company would help with any of the payment. Pete also helped us fight the warranty company to partially pay for some of the work. He was fighting for it even more than we were! what other company would do that for you?!?!?! Based on those factors we hired Dun Rite for our AC and ducts. The team was prompt and only took a work day and 2 hours to put in a whole new AC unit and ducts and discard of the old unit! When they worked in the house the team wasn't overly loud and they left the house super clean. After the work was done I realized Dun Rite was the same company that worked on my parents house 10 years ago and my parents praised their work then as well. this shows their standards have not dropped and they are consistent. I highly recommend Dun Rite without any reservations."

FAQs for air conditioning projects in Millburn, 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.
