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."

"What a amazing experience. We were referred to Temperature Zone Corp from a family friend, who had nothing but great things to say about this father and sons company. We immediately contacted Kevin & Co due to our household AC breakdown. Kevin was immediately available to us when we had expressed our emergency situation. Kevin made himself available to go over all of our issues with our inherited old unit that came with the house that had finally broken to no repair. Kevin listened to what we needed and addressed any concerns of enhancements needed to get the full capacity of cool temperatures throughout our home. Kevin and company reflected a high level of skill and attention to detail. They were not only efficient but also incredibly punctual, ensuring that all services were provided on time and without any hassle.

"This was the worst experience i have ever had with a company. They came and damaged my house and kept us without AC for days. They admitted to the extensive damage and went weeks before attempting to repair it. The services were never fully completed and they were paid over 90% of the job. I disputed the last 10% and provided overwhelming evidence of their negligence. And after a year their last ditch effort was to send collections letters. Don't walk, RUN from this company. I will provide pics and my my experience to anyone who is planning on using this company. Used to be family owned and was amazing. Second they sold it went downhill fast."

Heating and Air Conditioning questions, answered by experts

You need to service an HVAC system about twice per year, with a service including an inspection and basic maintenance. It’s best to schedule maintenance in the spring (after the furnace has been running and before the AC kicks on) and in the fall (after the AC worked hard all summer and before winter’s first chill arrives). 

Regular HVAC services will keep the system working as efficiently as possible, saving you money on utilities and larger repairs. HVAC maintenance costs around $250 per visit, while bigger repairs from forgotten upkeep could cost thousands.

No, a licensed local AC repair technician must replace AC coils due to the need to handle hazardous refrigerants. Attempting DIY poses risks to your personal safety, as most refrigerants are flammable and toxic. You also risk voiding your warranty with the HVAC company and causing damage to the unit.

Yes, a mini split AC system can replace central air—and quite easily, too. Since mini splits don’t require ductwork, homeowners can convert their central air system to a mini split to save money and energy. Consult with an HVAC professional to learn more about the process of replacing your central air with a mini split.

The $5,000 rule for HVAC systems helps homeowners decide whether to repair or replace an AC or furnace. Take the quote for the HVAC repair cost and multiply that by the age of the HVAC system. If the total is higher than $5,000, it’s more cost-effective to replace the system. If the total is lower than $5,000, consider repairing the system.

While 72 degrees is a comfortable setting for many people, it’s likely not the most efficient temperature setting for your air conditioning unit. By pushing the temperature up to 75 or 78 degrees, you stand to save money on your energy bill. That said, these temperatures may be too warm to be comfortable for some people and are definitely too warm for most people to sleep comfortably.
