"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!"

"I was in desperate need of an AC unit repair and Kyle came to the rescue. Iâ ve owned my home since 2019 and have been looking for and honest and reliable AC technician. Iâ ve used a couple of other technicians but Kyle will be my go to moving forward. He kept me informed of everything he was doing and educated me on how my unit should be running. He even gave me info for what filters I should be purchasing to help my unit run efficiently. He gave me several options with regards to repairs and I went with the higher priced option because it was so reasonable and I didnâ t want to cut corners. I will be scheduling my routine maintenance with him for the summer and winter. Iâ m so happy I finally found an AC technician I can rely on. I highly recommend him."

"My home warranty contracted out the job to Phase II. Robert came to troubleshoot a 30+ year old AC unit and was very honest about everything he found faulty. He was instrumental in convincing the warranty company to replace the entire condenser unit rather than continue putting band-aid fixes to this ancient unit. Few weeks after he replaced the unit that cools the upstairs, the other unit that cools the downstairs fails as well (also over 30 years old). Since he was already familiar with everything, the second unit was replaced as soon as weather permitted. I didn't even have to be home the second time since the work was outside anyway. The promptness of his repairs can not be overstated. He helped get us back up and running as soon as the parts were available on the next clear day, which we couldn't be more appreciative since we have both a toddler and infant at home. Also, this was during a heatwave when most of the week was 90+. On top of this, my son's 1st birthday party was coming up and we needed the AC back asap. We can't recommend Rob and Phase II enough, a true professional"

"A faulty compressor required replacing, but I was informed it was not worth it, and they would only do a complete AC system change, at a price $500 more than any other company in the area. I asked for a repair service, not a replacement service"

"Jay, came to see how to fix or change the central air, gave me an estimate with models and prices better than the competition that charged me $ 95 and $ 170 just to tell me what I already knew that the air did not work. Jay did not charge a penny for the first visit and the price for installing a new furnace exceeded the competition an quality and service. The next day he installed it. Perfect, I'm super satisfied and I would recommend it 100%"

"Peter and his crew were great. We replaced our steam heat and window AC units with their LG high-efficiency dual zone (heat and AC) unit. The air is great. The system adds moisture so it is not the DRY air that is typical of electric units. They showed up on time for the work each day. They were ALL very polite, clean, well spoken and knowledgeable. It is rare to be able to say that about ALL of the workers. We have an OLD home, and they worked around every obstacle that was in their way without tearing apart walls, floors, and ceilings like other companies admitted they would indeed have to do. Peter will take the time to explain anything you have questions about, so do not hesitate to ask. My wife and I had many questions and felt much better after asking them. They work with you and have the mentality that it is YOUR house so it should make YOU happy. They are not done after they get paid, they work with you to make sure everything is to your liking even after it is up and running. Oh, and it will NOT cost you more than the competition. In fact, it is just the opposite. So glad we went with them!"

FAQs for air conditioning projects in Dumont, 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.
