"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"

"Erik and Chris were absolutely amazing. Erik’s communication is impeccable—he explained everything clearly, from cost to timing, and made the whole process stress-free. My gas steam boiler failed during one of the coldest winters in decades, and they handled the removal and installation quickly and professionally. The job was done in just a few hours. I couldn’t be happier and highly recommend them.!"

"I recently had mini split systems installed in my home, and I couldn?t be happier with the entire experience. From the initial consultation to the final walkthrough, the team was professional, knowledgeable, and incredibly detail-oriented. They took the time to explain all my options, helped me choose the right system for my space, and answered every question without rushing me. Installation day went smoothly?the crew arrived on time, worked efficiently, and treated my home with respect, keeping everything clean and organized throughout the process. The units were installed neatly, with careful consideration to both performance and appearance. Everything works perfectly, and the difference in comfort is immediate. It?s clear this company takes pride in their work and truly cares about customer satisfaction. I highly recommend them to anyone considering mini splits or HVAC work?you?ll be in great hands."

Install Boiler questions, answered by experts

A furnace takes in cool air, heats it through the burner and heat exchanger, and sends the air on its way to warm your home. A boiler is a pressurized vessel that produces hot water or steam to heat the home and provide hot water. A boiler may or may not work together with a furnace.

No, there isn’t always water in radiators. In a one-pipe system, water is constantly circulating from the boiler to the radiators and back. In a two-pipe system, water travels through two separate channels: one that goes to your radiators and one that returns back to the boiler so it can heat up again.

It takes about five to 10 minutes for heat to reach a radiator, then about one hour until the radiator fully heats up a room. The exact duration depends on the size of the room and how far away the radiator is from the boiler heating system. Heating up an entire house could take up to two hours.

In most cases, repairing a radiator is more affordable than replacing it. A typical repair may cost between $100 and $200, while a replacement can average $1,500, with a range of $250 to $2,500 depending on the unit type. Radiator issues are often simple fixes for a professional, such as a blown fuse, malfunctioning thermostat, or a loose valve, and can take less than an hour. However, if the long-term costs of fixing the radiator are higher than replacement, it's better to get a new model. It is recommended to consult a heating expert to diagnose the problem and determine the best solution for your situation.

Installation costs range from $4,000 to $12,000, depending on unit size, efficiency rating, and labor.
