I learned about them through a friend and decided to give them a call. From the start their customer service was so assuring on being able to fix the system and having a team out asap. The service techs were super nice and let me know that it was a simple fix for them to swap some device out to help it start again( I know nothing about hvac and the lingo but they describe it so I knew the basics of what was going on lol). They generally were great and reliable with a nice pricing package. I valued the service they provided and will definitely will use them for services going forward.

Tru North was fantastic from start to finish. The technician showed up on time, explained…read moreeverything clearly, and didn't try to upsell us on anything we didn't need. It was refreshing to work with a company that's honest and transparent about the condition of your system. You can tell they genuinely care about their customers and their work. Professional, knowledgeable, and easy to trust. We'll definitely be using Tru North again and recommending them to friends and family.

We have four different systems at this place, a gas heater in garage, Mitsubishi cassette above the garage, heat pump, and a geo-thermal system. Finding someone who is able to deal with all those at once hasn't been easy. We found one company, but then he ghosted us because he had staffing issues. Kurt showed up for a fall check-up. First time here. And he found a filter in an exchanger/handler that all 3 previous HVAC people missed. The place had been vacant for 5 years before we bought it 2 years ago and it clearly hadn't been changed in all that time. We had an airflow issue on the second floor, and this filter was the 2nd stop up from the basement. All the prior companies had looked at the same piece of equipment and not one of them noticed there was a filter to be changed. Until Kurt. It was so filthy and clogged it's no wonder we had an air flow problem. That alone gets DiBiase 5 stars. But we've also used them before at our last property and they were equally knowledgeable, polite, educational, and effective. And they take thorough notes, pictures, and truly build a file on your property which says they know about relationship management and are in it for the the long haul. I'm a tough sell, but I'm sold on DiBiase.

Overall, this seems like a local company that genuinely cares about doing quality work and treating…read moreits employees well. However, I did experience an issue during my furnace installation. After the gas line was turned on, a gas leak occurred, requiring PECO to replace parts on the gas meter. Based on the PECO technicians' experience, they indicated that opening a gas valve too quickly can sometimes contribute to a gas leak. On the other hand, DiBiase explained that, in their view, the issue was not related to how the gas was turned back on but rather to the age of the PECO meter, which they believe would have failed regardless. To the company's credit, they discussed the situation with me and provided an additional year of free maintenance. While I appreciate their response and the added maintenance, I'm not convinced the installation wasn't a contributing factor. I hope they review their installation procedures to help prevent this type of issue from happening to future customers.

We also wanted an an estimate for a new humidifier, to change out the lavatory handles that had been installed backwards, replace a utility room faucet, and to do a general inspection of all the plumbing In our house. We have plans to add a new bathroom to our unfinished basement and he had good advice about that. The humidifier went in without a hitch! The handles on the lavatories were changed without a problem! The new utility sink faucet that was installed was a dream! My lavatory leaks though...these had to be tinkered wIth several times., on several different days. You are thinking, WHY FIVE STARS???? This is why! Our plumber came out several times, in a very timely manner, to make things right. He could have easily told us that this was a worse repair than what it was. He was unfailingly polite, and optimistic and got the leak problem solved. Everyone that I've talked to or dealt with at Mattioni Plumbing has been very profesdional and helpful. I look forward to calling them for our basement bathroom project because I am sure that they willl do it right, and more importantly, if there are any unforeseen problems, THEY WILL MAKE IT RIGHT!

Chip was here about an hour after our call, even though I let him know any day this week would've been fine but we appreciated the prompt service. The job itself was quite a challenge, the bottle was jammed in the trap of the toilet so after the toilet was removed and flipped over, it still took about an hour of perseverance to twist and break the bottle until it was able to be pulled out. It says something that Chip stuck with it and didn't just try to up-sell us to a new toilet install. Price was relatively reasonable so we didn't have any complaints there, no sticker shock. We'd definitely recommend Progress plumbing!

We got…read more7 estimates, ranging from companies that advertise on KYW and the back of SEPTA buses to smaller one man shops. We ended up selecting King HVAC and I'm really glad that we did. He offered us a modulating furnace and A/C for the same price as what another big player offered (they were selling a 2 stage system). His warranty was also beyond the standard 10/1, it was 13 years parts, 3 years labor. He sells Bryant, which is the same thing as Carrier. Wifi thermostat, he's running new gas lines for us, the whole thing. He's very professional and carried a book with him that included photos of his install. He pointed out where he would put the condensation sensors, how he would route the lineset, the whole thing.. which impressed me. He's also very accessible over the phone and pretty responsive over e-mail. Joe and his Dad spent a day and a half installing the system and were just awesome. Finally, two or three years later, we had a problem after a thunderstorm where the AC wouldn't run. I called him and he was able to swing by with only a few hours notice on a Sunday. He found that one of the circuit breakers was reset or maybe bad. He just flipped it back on and stuck around for a few minutes to make sure it was all good. Best part? No charge and he was here for probably a half hour on a Sunday. You can see the difference between a small operation like Joe and a larger place that advertises everywhere. The real value is in supporting a small business and you're rewarded with great customer service compared to the big, nameless companies.

Another company came out and gave a quote so I was looking for a competing quote. They sent out a guy named Chris who went into my basement to look at things and take photos.

I am baffled as to why they would have this guy come out and then just completely ghost me, but after experiencing this treatment, I wouldn't hire them anyway.
