John, James and Kyle went above and beyond the original scope of the work to do a proper install. Needless to say we now have an amazing unit done correctly.

Hopefully I won't need his services in the future but if I do he'll be my first call. Thanks again.

I understand that this is a very busy season but not a call or email for just an appointment is not good.

It's a shame because I liked the puppy sitting with the owner! Update on 07/1 I called again and this time I spoke with Christian who set up an appointment for 7/03 between 1-3pm.

Nothing but fantastic things to say about Central Air Systems and hvac technician Will who came to…read moreprovide emergency service for me in Ridge today. My upstairs zone AC air handler stopped working during this crazy September heat wave with temps consistently in the 90s all week. Called for an emergency service repair to try to get me up and running. They were able to squeeze me in only 2 hours after calling. Service call rate was extremely reasonable (half the price of others I called that weren't able to get to me for at least a day - even as an "emergency"). Inspected my condenser coil and pressure, air handler coil, and blower motor. Diagnosed blower motor control unit on the fritz / starting to fail, combined with super high head pressure due to clogged condenser unit coil. Was able to get me back up and running cleaning coil and jump starting blower motor within 30 minutes and unit cooling much better than it was before to hopefully get me through this heat wave before cooler fall temps come back. While they were here they were able to measure and run some calculations to put together an estimate for me to convert my upstairs zone over to a ducted heat pump setup, relocating my air handler for my second story upstairs zone to my attic from my basement and better plenum / air box design to help resolve lack of airflow issues also contributing to inefficient cooling upstairs vs replacing the blower motor in a 12 year old unit as a cheaper option. With that said service rep was very knowledgeable and transparent regarding the different options and cost effectiveness. Never felt like I was being pressured or sold in any direction, only given details to make an informed decision. Hoping when I get the estimate back to convert this zone to heat pump, taking advantage of various rebates (federal and state / PSEGLI as they are an approved contractor for utility rebates to stack), alongside attractive financing options to help with monthly budget crunch due to overall inflation from pandemic, that will be able to upgrade and save money in the long term vs trying to keep my 12 year old less efficient Rheem system running. Definitely going to continue to use Central air systems for service and preventative maintenance going forward! I will provide an update once I have the heat pump installed, but given my extremely positive service experience, hopeful that value on install and overall performance is also a 5 star experience. My pets thank you for helping to keep us cool during this heat wave Will!

I heard a hissing noise, which I followed and I'll be darned, there was water on the basement floor, which I traced to have been coming from the hot water heater. Panic mode set in. I called a local repair guy and he couldn't come until Sunday. NG. My first call was to Ferguson's plumbing Supply (formerly Blackman's), told them what the problem was, gave them all the specs about my water tank and they said they had it but they were closing at 12 noon. Made several phone calls, and they either went into voice mail or they couldn't be bothered. The main reason was that I was providing my own water tank. Less money to be made. Somebody that was not readily available, recommended Anthony from APV Mechanical. He called me, I told him my predicament and we agreed on a price. He gave me a time frame and his people showed up as promised. After I had agreed with Anthony to do the job, received several phone calls, and when I told them I already had someone, they underbid him by a couple hundred but I had promised Anthony that no matter what, he had the job. Ran like a maniac and purchased the WH, and Anthony and his people installed it in less than 3 hours, and my life went back to normal. Anthony and his people were very considerate, honest, efficient, very affordable, and pretty clean as his crew made sure that all the water was gone and ensure that both, my boiler and hot water heater were working. Based on my experience with Anthony and his company, I would recommend him, no questions asked.

Spend a little more and get someone who knows what they're doing. I have spent double the cost fixing his numerous mistakes and spent an entire summer without air conditioning waiting for him to make repairs. Trust me, run, don't walk away.
