"David and his team are always on time and deliver exceptional quality work. I did 3 big projects with them over last 2 years and will hire them again if needed. His estimates are very accurate and he will tell you when the project should be done. I recently had to call them right before 4th of July due to my boiler not firing. He came next day and quickly found the issue (the back draft sensor triggered and had to be reset). He explained why this usually happens and how to reset it myself. He and his crew had a project in my area and due to that didn't charge for this visit. This is the honest plumber I was looking for!"

"I have a 3 unit building in Hudson Co. that I have managed for almost 30 years. It was necessary to do major renovations years ago to bring the building up to code. Additionally, the building has 2 wall hung boilers that have been successfully repaired and maintained over the years. The boiler on the ground floor sits on the floor in the laundry room. Approximately 23 years ago, the sewer line running from the side of the house to the main failed. It was clay pipe that was deteriorated. Z Best plumbing dug a trench and replaced the failed sewer line with PVC pipe. Whether my projects have been major or smaller repairs, I highly recommend Z Best Plumbing for thorough, conscientious and professional work that is well done."

"It was a superb experience. From the visit by Bruce the sales representative to the installation day to the follow-up from Petro, every single person we interacted with was helpful and professional. When Bruce arrived to do the assessment, we spent time going over the heating needs in the house. After a thorough inspection and measurement of the house, we sat down. He showed me a few options, all of which were going to provide good service. I ordered a unit at the end of that meeting. The installation day was just terrific- the entire work crew that showed up were everything I would hope to find: Upbeat, informative, hard-working, focused. The job was finished before end of day as promised. The heater room is now immaculate, with new piping and a new heater. It was like watching a pit crew at a NASCAR race. Everyone had their tasks, they moved carefully but quickly. The materials were all laid out in order, etc. Just a totally professional approach to their work. The crew boss answered any questions I had. The follow-up for a normal inspection of the furnace chimney was scheduled the day after the installation. I’ve gotten calls to insure we are satisfied with the work. Satisfied barely covers it- I am pleased to write this kind of review. Without hesitation I will recommend Petro to friends and family throughout the Philly area. Peter A. Elkins Park"

"I used them to install a gas line and hook up a new gas stove. Vince was through and very knowledgeable of what needed to be done. The price was exactly what he quoted, the pipe install was very neat and clean and he connected the stove, tested to make sure everything was working as well as check all the existing gas appliances to make sure they were working after turning the gas back on. I will be using Vince going forward for all of my plumbing needs!"

"Great Experience with Kevin guiding us with the proposal of a Central Air and Furnace replacement. Very professional and answered all questions timely. No hard sell at all. We did have an existing Lennox AC. The install team of Shakil, Ty and Brandon were just as professional. True to their proposal, they came in and installed both systems in one day. Left the area neat and clean."

Install Boiler FAQs, answered by experts

The average cost to replace or install a new HVAC system is around $7,500. However, the price can range from $5,000 to $12,500, depending on factors like the size of your home, the type and brand of the unit, and your specific heating and cooling needs. If you only need to replace certain components, the cost will be lower; for example, a new AC unit can cost between $2,200 and $5,500, while a new furnace costs $3,200 to $6,000. If additional work like new ductwork is required, the total cost could be as high as $22,000. It's best to contact a local HVAC company for an accurate quote.

The right type of HVAC system will depend on several factors, including your climate, budget, preferences, and existing HVAC setup. For example, if you live in an area that experiences extreme weather, then a split system would likely be the best option. Or, if budget is a concern, consider installing a ductless system in just one room.

Chilled water HVAC systems use water instead of traditional components and refrigerants. They're more common in commercial settings than residential ones but are slowly being adopted by some homebuilders to cool homes. As the name implies, the system keeps the water chilled at 40 degrees and circulates it through water coils. The water absorbs the heat from your home and drains outdoors. Condo apartments are more likely to have chilled water HVAC than single-family homes because this system is designed to cool several rooms or large areas individually.

No, boilers and water heaters are not interchangeable because they serve different primary functions. Boilers are used for central heating systems, providing hot water or steam to heat your home. In contrast, a water heater's purpose is to supply hot water for daily household use, such as for faucets and showers. A water heater alone cannot supply the warm water or steam needed for a central heating system.

While they are not interchangeable, it is common to have both a boiler and a water heater. In fact, a conventional boiler often works best when a water heater system is already in place. The two systems can be combined to provide both heating and hot water, either by pairing a boiler with an indirect water heater or by installing a premade combination boiler-water heater unit. For home heating, some homeowners may also opt for a furnace instead of a boiler.

Generally, an oil furnace is considered safer than a gas furnace for several reasons. While both types of furnaces can produce carbon monoxide, a leak in an oil furnace is easier to detect due to the smell. Oil furnaces also don't connect to a gas pipeline, which reduces the chance of a fuel leak. Most importantly, heating oil is not combustible, whereas natural gas is highly flammable. This means there is a much lower risk of combustion or explosion with an oil furnace. However, an oil furnace can still pose a fire hazard if it tips over.
