The Speer family started their company in 1900 selling coal and oil to residents and businesses in Northern New Jersey. Speer Air Conditioning was formed in 1958 and incorporated in 1966. Since then Speer Air has attained a reputation as one of the top heating and air conditioning companies in New Jersey. We average between 35 and 50 employees seasonally. We are a Carrier Factory Authorized Dealer (FAD) and have a New Jersey Home Improvement Contractor's license, 13VH00978100 as well as a New Jersey Electrical license, 14873. We provide complete HVAC services as well as electrical services. Speer Air is also a Generac Home Stand-by generator dealer. We also will give a $100 discount in addition to Speer Air discounts and the many utility rebate programs that are available. We look forward to serving you and offer a 100% satisfaction guarantee .

"Changing my 5 star review to 2 stars. We have had a HE Boiler as well as a AC/Heat Pump installed by them. Unfortunately we needed service today. I was willing to pay for Emergency service. They said they couldn't make it out for 14 days, because we did not have a service contract. Spent about $25k for the installations. Which apparently means nothing to them What makes matters worse, the Emergency Service we paid through another HVAC provider was only necessary because of an issue they created during the installation. During the installation Speer Air originally ran the line for the residual pump over the copper hot water line. Which over time burned through the residual line, and then cause a hole and leak on the copper pipe."

"We paid thousands of dollars to AJ Perri for a new hot water heater and have had nothing but problems ever since. I?ve made multiple calls, they?ve sent technicians out multiple times, and the issue is never actually fixed. I?ve even had to call NJ Natural Gas more than once because AJ Perri couldn?t resolve their own installation issues. Their so-called ?Exceptional Service Guarantee? is complete bullshit. Right now, I once again have no hot water?which their own website clearly states is considered an emergency with service promised within hours. Instead, I?m being told they have no technicians available and I have to wait until tomorrow. Meanwhile, I?m left worrying about frozen pipes and further damage because of their incompetence. This is hands-down the worst service experience I?ve ever had. Overpriced, unreliable, and zero accountability. If you?re considering AJ Perri, do yourself a favor and look elsewhere."
