"Replaced a gas boiler and installed a new hot water heater. Andy did an excellent job. He was prompt and very knowledgeable. Worked a very long day to restore heat and hot water in the middle of winter."

"Working with Connelly Heating and Air Conditioning was a terrific experience. My mother had her furnace crack and become disabled right before the week of Christmas. Shannon was terrific to work with both on understanding that in the middle of December she could not go without heat, and that funds were limited. He took the time to find us a great replacement and even installed on the weekend to prevent my mother from having to stay in the cold for more than a day. Installation was incredibly quick and done well within our budget. I would recommend Connelly Heat and Air Conditioning to everyone as Shannon is terrific to work with and is there to help. Well worth more than 5 stars and will be the only person I call whenever I have issues with Heating or Air Conditioning."

Customers say: Quality work

"I have used Freedom Comfort Services in the past installing mini-split system and now (at another house) replacing an oil furnace with gas. They are priced better than the other companies that I got quotes from AND they took the time to measure the spaces in the house to know what I would need. They communicated great and were always punctual. When our old furnace went out they worked quickly to order a new one and when it came in, made sure it was installed that day. You can tell that they care! That's important to me."

"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"

Install Boiler FAQs, answered by experts

Boilers provide even heating, energy efficiency, and a quiet operation compared to forced air systems.

A furnace is a big unit where gas, heating oil, or electricity heats the air. The warmed air is then pushed back out through ducts and vents. 

A boiler uses electricity, heating oil, or gas to heat water that is pushed into the room through a radiator. This is one of the oldest and most effective ways to heat a house, but radiators can also be unsightly and leave hot and cold spots in the room.

Heat pumps use a refrigerant to move heat from outside into the house and return it to the room through ducts and vents.

One of the easiest ways to determine which type of furnace will work best for your home is to contact a professional in your area. Many HVAC companies offer free consultations to help potential customers determine if they need a new system and which type would work best for their home and the community’s climate.

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.

It can take anywhere from four hours to three days to replace a boiler with a new one. How long your particular boiler installation takes will depend on whether you need a gas line installed and if you’re switching to a new boiler system. 

Replacing a combination boiler or standard boiler with the same system should only take four to six hours. Meanwhile, switching from a conventional boiler system to a combination boiler system could take a few days.
