Heating & Air Conditioning / HVAC near Commack

“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.“

“Mark was the technician and did an excellent job in explaining the scope of work and possible issues. He was prompt, courteous and very knowledgeable. What waste time and money with anyone other than Dole. Would not hesitate to call them back anytime.“

“Hiring GMG HVAC to service our home is the best decision we could have ever made. Joe is seriously the best, most friendly person, and one who is knowledgeable in all aspects of home ownership and construction. Every time he has come out to our home, we are immediately put at ease and know that our problem is going to be fixed correctly.“

“Fast to respond to my call. Clean cut serviceman was at my house in about an hour. Work was done clean, professional and fast.“

“My central air was no longer producing cold air. When I called Christopher he was able to tell me most likely what the issue was and come by to fix it. I went with him because he instilled my trust and was able to deliver on what he promised.“

“I recently switched from another vendor to Five Star and am happy I did. At their initial visit they identified some maintenance issues, performed a tune up and returned that same afternoon after I called to ask a question about some work they performed. When their service tech Alex came another day to perform the maintenance recommended, he was knowledgeable, helpful, efficient and even braved a swarm of mosquitoes to attend to my AC units. Happy to recommend.“

“Andrew was responsive, respectful and resourceful. He not only serviced my dryer vent, he pointed out how the previous company I used negligently left in a screen which prohibited the release of the lint, blocking airflow and burning out my heating element. I highly recommend Andrew and All Island Dryer Vent Solutions!“

“Our central AC died, we decided to switch our oil heat to an electric heat pump with Yangklin Sierra/YasHVAC. Before going with Yas I spoke to ten installers to retrofit with central air ducts. Many companies told us to redo our entire first floor ductwork or supplement electric radiators in our bathrooms. Yangklin troubleshooted the quirks of our project with ease. The heat from the Daikin FIT is nice and even, more so than with our old floor radiators. The process was smooth.“

“Andy of Strikehard Mechanical has been absolutely awesome. He uncovered a complex wiring and systematic problem with my heating system. And he has been resolving it for me, step by step, in an honest and efficient way. There are still a few things to do, but Andy's customer service, knowledge, and kindness has been everything. I highly recommend Strikehard, and he definitely has a new customer in me. Thank you, Andy!Service: Heating system repair“

“Joe's Customs was a recommendation from a friend. I got top notch professional service at a totally reasonable price. Kevin, the tech was super nice and gave me a really trustworthy vibe. I've got no need to look anywhere else for my HVAC needs. Highly recommend.“

“Eric and his team did such a great job! Everything was done in a such a professional manner. They go out of their way to make sure all equipment and ductwork are installed in the neatest way possible. Can’t recommend this company enough!!“

“We had a home renovation taking place where we needed new ductwork added as well as consideration taking into what to do with the existing system. Mike and Energy Mechanical took a very pragmatic approach in providing a few "here's what I would consider if this was my house" options. On time, in coordination with our GC and never an issue getting a hold of them.We are very happy with the final results...so much so that our neighbor ended up using Energy Mechanical for HVAC install needed as part of an addition they did shortly after they saw our project completed.“

“I went here for AC material to repair my central air at my own house. They had all the material I needed“

“Max and his army are incredible. Everyone over at M&M Precision has been a pleasure to work with and speak to. They have gone above and beyond to help me on numerous occasions. Valerie is incredibly kind and so helpful. The guys are there on time, extremely knowledgeable, very friendly, and great at what they do. They get the job done and leave you with no mess or worry. Can’t thank them enough.“

“I have been using Genesis for over 20 years (at minimum) and had an unfortunate incident recently at my home. A driver was nervous about the street I am on and decided to part partially on the sidewalk for safety. Unfortunately the weight of the truck damaged my sidewalk. The owner called me immediately and was courtesy professional and not in the least defensive regarding the incident and all of this was prior to him reviewing the photos I took. He understood my concern and rectified the matter within 48 hours by sending experts to fix the issue. It is refreshing to deal with a business that stands behind their name and appreciates their customers. Thank you guys very much.“

“Fantastic! Had A/C condenser and air handler replaced. Chis and Danny were great. They are neat, efficient, and a pleasure to deal with.“

“They repaired my oil burner 12/23/2020 great honest service. Mechanic was polite, knowledgeable, honest. Thank you so very much. It’s so nice doing business with a company with integrity“

“We recently purchased a home in Northport and were taken aback by the high heating and cooling costs. To address this, we engaged Adam, George, and their team at Analytic Energy to install three heat pumps and revamp our ductwork. Our experience with Analytic Energy was nothing short of fantastic. Their expertise in modern heating and cooling technologies was evident. They advised us on top-notch technologies, identified gaps in our insulation strategy, and guided us on maximizing rebates from PSEG. It's crucial to have someone who deeply understands the intricacies of heating and cooling systems since it's such a technical field with numerous choices to consider. Throughout the process, Adam prioritized optimizing our system's efficiency without overselling or inflating costs. Both Adam and George were punctual, meticulous, courteous, and always ready to help. Of all the contractors we've worked with, they are by far the most reliable.Services: Install thermostat“

“Just put in a new compressor and air handler. Bill was very helpful in providing our options and making suggestions. The installation was needed quickly and Bill made that happen.“

“After a nightmare of dealing with a bad radiator system and other companies that didn't follow through or gave us outrageous prices.. these guys really came through. They spent many days at my home that was thought to be a smooth install but ended up being very convoluted and delivered a very neat install of two central units with heat pumps. Very easy to talk, clear communication, sticks to his word, to and can tell he cares about the people who use his services. Thank you for everything :o)“
