“We have always been completely satisfied with the response for service from Weismiller Plumbing & Heating. Their availability, expertise and price are without question. However, on our most recent need, that of installing a dishwasher under the counter of an aging kitchen, they were beyond our dreams! Marcus spent 2 1/2 hours here with a project that seemed hopeless; nevertheless, he championed every detail, and enabled me to keep the countertop and flooring surrounding the space intact. (All of this did not appear possible for any of the painstaking work and effort he put into it.) But, he was a "miracle-worker" and I cannot thank him and Weismiller enough! Mrs. Peter Hertling“

“I just had Diamond-N-Blu install HVAC and all I can say is that they are one of the best run companies I've ever had the pleasure to work with. If you call them they answer and address any situation. I sent 5 emails during the corse of the job and they were answered immediately and the company made sure that any and all of my concerns were taken care of. Nick, Curt and Zach did a great job! Very pleased with their work.“

“Always available and always helpful. Before I was on an auto schedule, I ran out of oil on Thanksgiving weekend. They were the only company willing to help. Since then I have been a loyal customer. They also do plumbing work and are the first to come out if I have a flood or any other trouble. If the work is out of their scope, they assess and help me find someone. Wonderful company.“

“Just a great business! Needed a propane line installed for new gas range, Lori in the business office was so helpful, courteous, prompt replies, scheduled the work quickly and followed up to make sure we had what we needed for Town of Brookhaven Building permit. Plumber Mark and his partner Jesse did a terrific job from start to finish installing piping neatly and ensuring gauge would pass Town inspection. Once approved they returned and connected range to gas line, converted range from natural gas (as shipped) to propane, tested everything and fired it up! So happy with their service, polite, neat, efficient. Highly recommend! Thanks to A to Z, we're cooking with gas!“

“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.“
