"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 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."

"Reliable, great customer service, and honest. Highly recommend them for all your heating and air conditioning needs. Alfredo came in and diagnose my furnace. He’s very knowledgeable and solved my furnace issue the same day. Went above and beyond to ensure the heat works like I informed the entire process while I was at work."

"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+++++"

"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"

"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.
