What Happens After You Submit
- Your request goes straight to our office team, who read every one.
- We call or text you back, whichever you chose, to ask a few questions about the system and what it is doing.
- We book a visit and give you an arrival window. For no heat, no cooling or a leak, tell us and we treat it as urgent.
- The technician diagnoses the problem and gives you the cause and the price before any work starts.
We Answer 24/7
Heating and cooling problems do not wait for business hours, so we answer the phone around the clock, including nights, weekends and holidays. Call or text (631) 414-7141 and you speak with a person, not a voicemail tree. If you smell gas or a carbon monoxide alarm sounds, leave the house first and call the gas utility or 911 from outside.
Where We Work
We serve homes and businesses within about 15 miles of our shop at 60 S 2nd St, Unit V in Deer Park, across western Suffolk County and eastern Nassau County, from Huntington and Commack to Babylon, Bay Shore, Massapequa and Farmingdale. See every town we cover on our service areas page.
Financing
If the answer turns out to be new equipment or a major repair, financing is available through Rheem KwikComfort, with credit provided by Synchrony Bank, subject to credit approval. Ask when you call, or read how it works on our financing page.
What Our Customers Say
"Waseem is excellent. He checked my hearing system, diagnosed the problem and fixed the whole system. Now the heat is working excellently. I am high recommending this company to any person’s house. He is very thorough and spent as much as was needed to repair the heat. We are very thankful. He is excellent. Thank you so much to your company."
"This is my second (distinct) job with K2 HVAC and I couldn't be more appreciative of their prompt and quality services. The first job (a replacement of my heating unit) was handled excellently by Shelby and the second (a replacement of my hot water unit) was amazingly handled by Waseem. The backend customer support is fantastic too, as Sadia is ever responsive by text and phone call. All said, I recommend their services wholeheartedly!"
"This was my first time using K2 Cooling & Heating, and I couldn't be happier with the experience. Waseem arrived on the scheduled day right on time and took the time to listen carefully to the issues I was having with my HVAC unit before beginning any work. He quickly diagnosed the problem and explained everything clearly in a way that was easy to understand. His professionalism, knowledge, and attention to detail were outstanding. He fixed the issue efficiently and made sure everything was working properly before he left. It's refreshing to work with someone who genuinely cares about providing excellent customer service. I highly recommend Waseem and K2 Cooling & Heating to anyone looking for honest, reliable, and knowledgeable HVAC service. I will definitely be using them again in the future!"
Frequently Asked Questions Before Booking
How quickly can K2 dispatch an emergency HVAC technician?
We answer 24/7 and dispatch from our shop on South 2nd Street in Deer Park, close to the Long Island Expressway, the Southern State Parkway and Route 231. For a no-heat call in winter or a failed air conditioner in a heat wave, we send the nearest available technician and give you an arrival window when you call (631) 414-7141; timing depends on the day's demand and the weather.
Do you provide upfront pricing before performing repairs?
Yes. Our certified mechanical technicians perform a thorough diagnostic evaluation, explain the failure plainly, and present fixed, flat-rate pricing before turning a single wrench. We never begin work without your explicit approval, and we have zero hidden truck or dispatch fees.
Are your technicians licensed, insured, and certified?
Every member of our field team is EPA Section 608 certified for safe refrigerant handling, fully insured, and extensively trained on all modern inverter heat pumps, traditional split AC systems, gas furnaces, and high-efficiency hydronic boilers.
Where is K2's dispatch headquarters located?
Our central operations headquarters is located at 60 S 2nd St, Unit V, Deer Park, NY 11729. Technicians dispatch 24/7 across Suffolk and Nassau Counties.
