Get matched with top boiler installation pros in Flourtown, PA

"I had the quote done in December and was hoping to nurse my 44 year-old boiler through 1 more winter. Well my boiler said it’s final goodbye in January-2019 so I moved forward with a new hot water boiler. I was able to schedule the installation within less than a week which I thought was good. The installation took the better part of a full day but was not really much of a bother as the team was able to access the basement through the bilco doors on the street. At the end they walked me through all of the work completed, answered questions and let me know to call them if there were any problems. A month into use it’s working perfectly and I am very happy about the whole process."

"Mike Anderson was the technician and he did a great job with installation and estimates for future service."

"From the initial call to the office through the installation process, the experience with Christian was top-notch.  Mark, our HVAC specialist, was very professional and attentive as he worked with us to chose our new system and schedule the installation.  He was in contact with us throughout the process, even being there on the day of installation.  The installers, Ed and Dan, were also very professional.  They installed the new indoor and outdoor units, humidifier, and thermostat under the time estimated, gave an orientation to the new system and controls, and left our home without a trace of the installation, other than a brand new, highly efficient heating system.  I would highly recommend Christian.

"Furnace was not operating because the company's automatic delivery system ran me out of oil.
Technician showed up promptly and got the furnace operating but could not get heat into the house. Had to reschedule to have zone valves replaced. Technician show up late and didn't have the required parts. Had to reschedule again.
The third technician showed up on time with all the correct parts and worked most of the day to get the system operating properly.
He was completely knowledgeable and very conciencious that everything was working correctly.

"Patriot was awesome from the start. I got 3 estimates for the same Trane AC units, removal of 2 very old systems and install of 2 new systems and they were the best price by far and offered a 2 year labor warranty on top of it. The removal and install went great and Will wouldn’t leave until I was 100% satisfied with everything. Highly recommend them for any heating or air conditioning needs."

"Dante and Joe took great care of us when our furnace failed in the recent cold spell. The other people we called couldn’t come out for days but Valley Green was able to fit us in right away and were cheaper than the other company which was trying to take advantage of our urgent problem. If you want an honest locally owned business, I recommend them 100%."
