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."

"Marlon ghosted us before finishing the work we agreed upon and paid for. He completed 75% of the work, then as soon as he received payment he became incredibly hard to reach, started dodging phone calls, setting up appointments and then not showing up. It was incredibly frustrating to have our time and money wasted."

Energy Efficiency Auditing questions, answered by experts

A blower door test shouldn’t take more than an hour, and most can be completed in less than 30 minutes. Expect the test to take longer once you start searching for leaks with thermal imaging or want to include sealing such leaks in the time estimate. The test doesn’t take much time and can’t be rushed, but it will take longer in large homes or those with many air leaks.

Yes, advising on models that save electricity and reduce utility bills.

Homeowners may qualify for an HVAC tax credit if they install an ENERGY STAR®-certified HVAC system that exceeds the energy efficiency minimum standards:

  • Split-System AC: 16 SEER2

  • Packaged AC: 15.2 SEER2 and 11.5 EER2

  • Ducted Split Heat Pump: 15.2 SEER2, 7.8 HSPF2, and 11.7 EER2 

  • Packaged Heat Pump: 15.2 SEER2, 7.2 HSPF2, and 10.6 EER2

  • Mini-Split System: 16 SEER2, 9 HSPF2, and 12 EER2

You can claim up to 30% of the cost of the job, subject to maximums.

If your AC runs constantly, it could be due to a number of things, including a faulty thermostat, incorrect temperature settings, or broken equipment. Alternatively, you might have an airflow problem (for example, blocked vents or leaky ductwork). Either way, an HVAC pro can identify the specific problem and fix it for you.

Depending on property size and audit scope, costs range from $200 to $600.
