"Spoke to Damian Tuorto regarding the project to Install a Central Air Conditioning System and said that it had already been taken care of so asked if there were any other upcoming projects in mind and he said not for now so advised about the 600 categories and to download the app or visit the website if anything was needed.

"Ali came over to our home when we called with a concern of the air flow in our central air conditioning system. He checked the return, the air flow, the temperature at all of the vents, and the entire system. It had more to do with the age of the system and gave us suggestions on how a different filter could increase the air flow. He did all of this and refused to take any money for his time. He is a true honest professional and someone that we would recommend to everyone."

"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."

"High quality, responsive, fair, and clean These guys are the best! We worked with them on a water heater replacement and a air conditioner repair/replacement - both in July 2019. When our water heater broke, we called several places. They were the first to respond - Ahmad was able to come out to our house within an hour or so. He answered our questions, let us know why he knew it needed to be replaced (as opposed to repairing a link), and began working. He noted that our previous water heater had been installed incorrectly, and he re-welded a pipe so that the new water heater could be installed on a more level surface. While he was at our house, we asked if he could also install a new kitchen faucet that we had been meaning to replace. He was able to fix it in 20 minutes. For both repairs, he left the worksite clean. I'm glad our water heater broke that day, because we learned they also do air conditioner repair. Dean was much more knowledgeable and provided us with more repair options than any other company we had contacted. We had been under the impression that both our air handler and condenser needed to be replaced, but he let us know that although the condenser needed to be replaced, only one part of the air handler - the coil - needed to be replaced. This saved us thousands of dollars. Dean also patiently answered our questions about other air conditioner options we were considering (e.g., whether to get a a unit with greater capacity). While we were waiting for parts to be available, they did a temporary fix of our old air conditioner so that we didn't melt during the heat wave. On the day of the repair, everything went smoothly - they kept me informed about progress and cleaned up after themselves. I'll definitely call Green Apple the next time I have a plumbing or HVAC issue!"

"My wife and I appreciated the time Wayne took explaining what needed to be done and answered all of our questions prior to and during the installation. He and his crew did an excellent job installing the 2 high efficiency HVAC systems. Both systems are running well. I thank Wayne for his ongoing dialogue during the installation which gave us confidence in the quality of his workmanship. Even though the systems installed were an upgrade the cost was less than all the other installers that gave us price quotes for the project."

"I had the equipment replaced, a brand new, super high efficiency, fancy, lovely stuff. It's a central air system, and it's Lennox equipment. It's high efficiency. You can get it for less than that, but you're not gonna get the high efficiency quiet and all that kind of stuff. I had received other quotes which were like more money for the same system. I have been using them since 1986. No complaints. They do their thing, and I can't fault them. I have a service contract with them for this."

"I highly recommend this company!!! This is someone who knows their stuff and is willing to go the extra mile to really get the job done! Our heating oil ran out while we were away and we came back to a freezing house and an odd puddle of water coming out of the heater. Thanks to Desmond, we were able to get the heater back up and running properly within a day!! Excellent customer service and very professional! I have used them before and will definitely be using them again!!!"

FAQs for air conditioning projects in Mahwah, 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.
