"Excellent! The team worked diligently for 5 days to install a central air system in our old house with Plaster Walls. It was NOT easy, yet they did a fantastic job. They were able to add all ducts to the first floor with out any "chases" or enclosures requiring to be build. And almost none of our first floor lines up with our second floor closets, but they figured it out. Great time and fantastic service. Make sure you get Brandon and Sean. The work their butts off, and ensure your house stays clean (they cleaned up everything after every day - not an easy feat). Cannot say how happy am I with their work!"

"I was having a problem with my air conditioning. The thermostat was blank. I called Ray?s HVAC. They came over and identified the problem. Then they came back two days later and fixed it. Everything is working fine now. I would use them again and recommend them to people I know."

"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."

"ABCastello HVAC removed old A/C inside and outside units which were 25 years old from my 2700 sq feet 2 store colonial brick face house. Old units were replaced with new and more efficient units - TRANE 4 ton two stage SEER 17+ ECONET (condenser model RA-1748-AJ2CB, air handler model RH-2T-4821-MEACJA and communicating module Econet STAT model RETS-T601-SYS). Excellent work quality! Fast response! Very reasonable price quote for 10 years parts warranty and 5 years labor and service warranty! Honest and hard working person! All work was done in a couple of days (including old unit removal)! I am very happy and a very satisfied customer of his service for life!!! A+++++"

"Home Advisors directed me to an online scheduling program and within 30 minutes of an appointment being scheduled I received a verification call from the provider (Robert at Phase II). The next day he shows up on time and in the course of doing the repair (unit needed more refrigerant) he also went into the attic to ensure the unit was working properly and he verified the thermostat was in working order. So he touched all the bases. He finally left when everything was verified in working order. But the BEST CUSTOMER SERVICE was the phone call a week later to see if the air conditioning was working properly. Wow....I've never had a contractor follow up like that!"

"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 Parsippany, 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.
