Heating & Air Conditioning / HVAC near Commack

“Highly Recommend! Quickly serviced my dryer for a good price. Very friendly and professional“

“ZBF recently installed a whole house (3400 sq ft) Series 7 Waterfurnace at my house. It's been running now for a few months. Overall the system works very well and is very efficient. The cost of the system was actually less (after rebates) than replacing the oil boiler with gas and installing central air without even factoring in energy savings. Attachments: (1) original oil boiler and hot water heater, (2) new Waterfurnace Series 7 Geothermal Heat Pump, hot water collection tank and hybrid hot water heater (all installed by ZBF), (3) Symphony dashboard screenshot. ZBF Pros: I would highly recommend Zach and his team for a geothermal installation. I shopped around when I was first interested in upgrading and ZBF was by far the most knowledgeable in these types of systems. Other HVAC contractors will install them but it's not their specialty. Zach was very flexible given COVID restrictions and getting into our house. He also took a lot of time to lay out the ductwork in our basement so that headroom would not be an issue. I couldn't be happier with the layout. I was honestly a very demanding customer. I'm an engineer and I overthink everything. Zach was extremely patient and walked through all of the options with me. He even was able to score a hybrid hot water heater from a distributor at a good price and didn't charge me anything extra. ZBF Cons: Not really a con, but discuss all of the relevant installation details up front so you know what to expect. I was somewhat surprised after the installation that some things I assumed were included were not. Patching drywall, reseeding the lawn are not included. We had very minor construction issues (and there are always issues). Some areas got dirtier than expected and needed to be cleaned (cutting tile is apparently very messy). Items that were forgotten or missed. Zach was very good at addressing these. Waterfurnace Series 7 Pros: This is one of the most advanced systems on the planet. Everything is variable speed and optimized for comfort. On milder days (above freezing) you almost can't tell that the system is running and it keeps the house very even and comfortable. The monitoring system is great (picture attached). My oil bills were $4000+ per year prior with the upstairs at minimum settings. My December electric heating bill was roughly $300-350 heating the entire house to 72+ so I expect to have a significant reduction in energy costs (at least half). Plus I now have central air which is a major upgrade. Waterfurnace Series 7 Cons: Upon commissioning we had an initial period of a couple of weeks where the system would trip offline regularly and even burned up a blower motor. COVID quality issues are likely to blame. I believe the reliability of these units is very high in general and I haven't had any issues since. While the system allows for very even heat in general it didn't quite live up to the marketing (to control temperature within a half a degree) on colder days. Also heat pump forced air systems do operate differently. In order to maximize efficiency there is a tradeoff during very cold times where the house will be allowed to cool down before auxiliary (resistive) heat kicks on. Fortunately these settings can be adjusted to maximize comfort vs economy but it does require tuning.“

“Gas boiler repair with Technicians Cliff Erickson and Tom Hebrank. Prompt, efficient and courteous service performed with integrity. Would highly endorse their services on behalf of Dashing Dans to anyone with a plumbing or hvac issue.“

“Joanna was great, explained everything well and offered up a lot of different options.“

“The night before we were about to host Christmas Eve our heat went out and the pilot light would not stay lit. Youtube could not solve this problem. I remember seeing Gallett Air on Greater Long Island and decided to give them a try. Mike came out that night and fixed it within a half hour. Mike is the man! He explained what he replaced and how the new part will help the furnace work more efficiently. 10/10 recommend this company.“

“We had an appointment for Residential Spring Maintenance today, and Tyler did an outstanding job. He arrived on time, was courteous, and even brought his own shoe covers—which I truly appreciated, especially with carpet in the house. The inspection was thorough, and he took the time to explain everything clearly and offer helpful advice. Tyler was both professional and polite. Five Star Mechanical continues to impress us and we’re happy with their excellent service.“

“Service persons were friendly and personable. They were very efficient and did the maintenance fast.“

“Excellent service. Quick and efficient dryer vent cleaning. Would definitely recommend and will be using this company again in the future.“

“Joe did an exceptional job for us. 5 different companies came and gave us the run around and took our money.

Joe came and spent 3 hours looking at the air handler, thermostat, running to his truck and fixed the unit and we finally have our air conditioning back!“

“Super happy we took the plunge. And replaced AC units with heat pumps. They're quiet, efficient, and crushing our heating oil use.

Likewise, working with Eric and the team at Cool Pro has been an absolute pleasure. Even when we've had a rare issue, they've promptly addressed it.“

“Can’t say enough good things about the guys at Advance. My Ductless system went dead on a Friday afternoon after 12 years during the recent heatwave. They came and had me up and running with my new unit that Monday.Calls to other companies told me at least a week or more. Very Professional Thanks again“

“David is a great tech . He is very knowledgeable and took his time and made sure bleeding of furnace and thermostat was done properly.No more cold nights!?“

“I just signed up for Homeserve yesterday, and am still in the ten day waiting period before the contract begins. Due to a poor distribution of heat affecting our main living areas, I called Homeserve this morning to see if they could dispatch someone on an emergency basis before the big storm this weekend. They were so helpful and got a technician in within 3 hours of my call! John was really thorough, kind, and did his best to address the issue. Turns out we have a major airflow problem, and there will be work needed in the future. He was able to quickly diagnose and rectify the problem for the time being. Thank you for coming to the rescue! Before calling homeserve, we had other people whom we had called who either could not make it due to distance and weather, or who made the original problem a bit worse. I am glad I signed up!“

“Antonio and his team were great! They are very knowledgeable and finished the job in a timely matter! Would recommend for your hvac needs!“

“I have been a customer of them for years. They are always reliable. Explain everything that they’re doing. And reasonable in their prices.“

“This past Sunday, during the coldest winter that we’ve had in years, our burner conked out. I have a premium service contract with Slomin’s and they came the next day. They sent a kid who wasn’t sure what the problem was and he said that I probably needed an inducer motor, which would cost me $575. I asked Slomin’s to send an experienced technician but they refused. My son in law, Trio Sheet Metal, recommended Ryan Anthony. A technician came today and found the problem immediately. There was a clog in the inducer. I didn’t need an inducer motor like Slomin’s said. I’m so thankful to Ryan Anthony, not only for their skilled service, but also for their honesty. Thank you.“

“I was able to get an appointment next day which was great. Phil was professional and experienced and was able to answer all of my questions with honest answers. He conducted a very thorough review, even more than I expected.“

“Mr. Felix and his assistant came to our house yesterday to fix some water circulation problem in our heating system. The job was done very well - clean, precise, and professional. We appreciate not only his good job, but also his communication to us. He explained how the new parts fix the problem so that we have a full confidence and a peace of mind. Thank you.“

“Chris was awesome he came to my father’s house to check his heat, explained everything clearly, was friendly and honest. Highly recommend asking for Chris, thanks again!“

“The boiler stopped working, would turn on then turn off in a few hours.. No hot water!
I called Jet Air, and they scheduled me in quickly.. The technician Nick, arrived promptly, he was professional, courteous and he knew his boilers. He diagnosed it immediately, needed a new valve, he replaced it and we had hot water again! The price was reasonable and fair. I would definitely recommend this company to friends and family.. Very knowledgeable and professional!
Thank you again Jet Air!“

“I had a ductless system replaced last year and Joe and his team were a pleasure to work with. The new system works great !“

“Called them on two separate occasions!
From the people who answered the phone , to the service repair people who showed up . Everyone was professional and really helpful and nice .
Repairs were done on my boiler. All went well .
Would recommend All service heating and cooling!!“

“Matt and the guys did a great job for a great price replacing my entire old HVAC system. I highly recommend Deer Park Avenue Heating and Air Conditioning.“

“I cannot begin to say enough about this company! My central air died on a hot day. I called them early morning and they came right away. The system was very old and needed to be replaced. I fully expected the usual… we have to order the unit and wait then schedule an install. Well I was wrong…. They said they could have it installed the same day! REALLY SAME DAY!!!! The crew led by Phil was incredible and they were neat and careful with everything. They left everything immaculate. The system is much better than my old unit. On top of all this the price was very fair. It is rare to get this kind of service from a contractor these days. Hartmann’s exceeded my expectations in every way.“
