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!

Then I had to have a draft test, then they came out another 2x for property pictures. So, no hot water no heat. Then summer came & went. Whenever I called LIHVAC, the line rang & they used their caller ID & sent me to voicemail. So I then started hiding my phone # & they'd answer. But still, they blamed NYSERDA for the delays. Here comes November!!! I call LIHVAC & am told that they are no longer using the NYSERDA pgm. So they gave me NO courtesy call, rejected my calls, ignored my emails. Terrible & irresponsible company. So that was 7 mos without heat & hot water. I called NYSERDA the last time & they gave me a company that they say they stand behind. I had nothing to lose, so I went with GreenTeam LI. After 2 preliminary visits, I was up & running w/a heat & hot water before Thanksgiving. LI HVAC lost out on $36k since I went with the heat pump! They should be ashamed of themselves. I can imagine how they take advantage of people. Poor excuse of a company & they deserve to close. Take notice & don't use this company. Horrible service & despicable & lack of morals.
