Premier HVAC Services
Premier HVAC Services
When you need help with your heating, ventilation and air conditioning, you don’t want to hear that your technician is stuck in traffic. You won’t hear that excuse from us. We’re based in Brooklyn, at Sheepshead Bay road - in an office, not a phone drop or a postal address. It gives us quick access to many of our customers. But we also have workstations in Staten Island and Long Island. This way, our techs can quickly help you, whether you have an emergency or a routine call. They can rapidly fan out across Manhattan, Queens, Brooklyn and Long Island, ready to install mini-splits and portable AC units, clean chimneys, service residential and commercial HVAC systems, solve your radiant heat problem or get your furnace running more effectively. Our techs are experienced in all sorts of HVAC installation and repair, from heat pump systems and oil furnaces to air conditioner compressors and ac units. How we began As veterans of the industry for more than 10 years, we formed the company in Brooklyn in June 2016 with just one van and one technician. Fortunately, satisfied customers have rewarded us with many referrals and now we have seven vans and 15 people on our team, including office staff. We’re very proud and very grateful for our success. The team leader is Greg. He oversees all three locations and keeps us organized, making sure we respond to calls and we don’t leave until the customer is satisfied. Our techs are experienced, licensed and insured. We can help you, whether you want a new heat pump, a boiler repair, clean air ducts or a commercial HVAC overhaul.
"I called Premier HVAC Services for a routine check-up, and they never showed up. After waiting 3 hours, they rescheduled for a week later without any apologies. Completely unprofessional and unreliable. I wouldn’t trust them with my HVAC needs."

I perform specialty shrub pruning and tree care consultations. I do all the work myself, so you know your plantings are in good hands. I use only hand pruning techniques to ensure the right cut is being made at all times, all equipment is sharp and sanitized between properties. Why me? Well I am a college educated, military veteran, Eagle Scout, and have over 5 years as a Certified Arborist providing consultations and pruning to customers in Fairfield County. I am also a Master Gardener with the University of Connecticut and would not mind designing and installing some plant material for you. I left the tree care industry because I was tired of corporate sales strategies pitching highly priced services with average talent. The only thing I could control was how my customers viewed me as a consultant. Now I can bring the industry knowledge, horticultural background right to you, and I control the quality of the work. I am looking forward to bringing that quality to you!
