My sister bought a house outside of Princeton in 2023. Prior to the sale, the owner had Condon…read moreTotal Comfort install ductwork through the second floor to the attic in order to get AC and heat to the upstairs bedrooms. As a general contractor with over 20 years in business, I was not impressed with their work. They ripped out whatever was in their way and left a mess that had to be fixed/covered up. In one instance, they only needed a couple inches and they could have installed the duct behind a closet wall/bi-fold door but instead they busted up the trim and tore out framing to do their install directly in the way of the door. I understand that the owner who was selling the house probably didn't care - they likely just wanted the "cheapest" thing done to get the sale, but it showed a distinct lack of foresight AND a lack of respect for the new owners (my sister, brother-in-law and their kids). It really isn't THAT much more difficult to CARE about one's work! Based on that, I cannot recommend them.

We have been asking for a year to please come out and stop the banging noises in our ducts, it is absolute torture at night to listen to. They came out once, hit the duct with his fist and called it good. It has gotten worse with time I have 6 emails to them to please fix it, no response. Now we are reaching out to other companies to see if they can fix it, litigation will follow if there is a cost. this is not the way to treat someone when they spend a lot of money on a new HVAC system.

June 13th- blower on furnace pukes. Called Ryf. June 14th…read more- technician called me from his phone. Said he'd be going over to look at issue. About 1/2 hour later, received phone call from technician's informing that it was the blower and it would need to be ordered. He said he'd let me know if he can get part. June 15th- No word back. Texted cell number of technician if he was able to order the blower. Technician responded back that yes, it would be in tomorrow. June 16th 7:17am - Texted technician to let me know when blower can be installed. Received no response, until 4:28 pm when I missed phone call. Called Ryf back and went to answering service. The answering service told to call Ryf back at 7:30 am on Friday as this was emergency phone service. I saw a voice-mail on my phone and listened. All it said was to call Ryf to schedule time tomorrow. Texted technician to let him know I received message and tomorrow is good. Received a message back saying he didn't send message and call shop in the morning. Received a second text from technician stating that this was his personal cell phone and to stop sending him texts. June 17th 7:30 am - 7:45 am - Called Ryf 7 times and kept going to answering service who had no way of contacting technician or employees. Found a number on my phone that came after the call from Ryf. Spoke with second technician who berated me for sending early morning texts to first technician. I told this second technician the first technician initiated the conversation by calling me on his personal phone. Second technician says in an unfriendly, threatening tone, 'Do you want your blower installed?' I said yes, to which he says I have to be patient and it will be installed today or early next week. I told the second technician that I have been patient and haven't heard anything back to get this scheduled; and that I called immediately after last night's phone call from Ryf and it went to the answering service who said to call back tomorrow at 7:30. The technician said he'd meet me at the house. The technician that did show up was rude, walked right by me stating his name, then asked how is this being paid for? Not so much as a sorry, good morning, nothing. As I write this, it is understandable how these companies completely believe that the customer is never right as they rake you over the coals. I do not recommend this company for HVAC services to anyone. Rude, inept, irresponsible employees. The company is unprofessional and will not keep in touch with you. And some advice for the company: if your employees don't like receiving text messages from customers, don't have the employee contact the customer from their personal phones. If your company says you open at 7:30am, then have an employee there at 7:30 am to answer the phone, not the answering service. Give classes to your employees on customer service. It goes a long way.

We had them out last year for a tune up with no issues, but this year when they came out they charged us an extra $50 for a "trip charge" after the service was done that no one told us about prior. I called and asked why I was getting this and they told me "every other heating company charges this now" but I called around and none of the other local companies do. The other issue I had was that they came out for the tune up on 12/15 and our payment didn't pull from our debit card until 2/2. When I called to ask why they didn't pull the payment for 6 weeks the guy blamed it on our debit card which is false. Someone there messed up and didn't run the payment right away. I would probably still use them if there had been any sort of apology for not telling us about the trip charge and waiting so long to run the payment but the guy I spoke to just kept trying to pass the blame and didn't offer any sort of apology. Terrible customer service and shady business practices.

Furnace was at the end of its life expectancy. However, when the other gentleman came and looked at the furnace, he told us the furnace is built to last 30 to 40 years and parts are obtainable.

HORRIBLE service and even worse quality. I called Randy to update plumbing in my house I am…read morerenovating. Originally I had him install a water main shutoff and I liked him so much I had him replace the main stack and rough in plumbing throughout the house. From this point on I realized what a lousy businessman Randy is. During his initial time here giving me an estimate he told me he would get the necessary permits and I don't need to worry. When you call R and R Plumbing you will reach Randy's wife Dawn. If you call there in the morning she will answer the phone, but is always pre occupied talking to her crew and complaining about how busy she is. If you call in the afternoon Dawn may or may not answer and if she does she is "away from her desk" and may or may not return your call. Randy was very quick to say he could find a better toilet that I could buy in store. I said ok great do you have a picture because I don't want just any toilet? Nope. "I will have the guys pull one out of the box and have Dawn send you a pic" That never happened. Even after asking a second and third time, I said the hell with it and found one myself. Moving along, I wanted a washtub installed in the basement and it was the same line as before. "I can find you one way better than you can find in the store" Okay great get me one. That never happened either. Not only did Dawn keep sending me an invoice for $100 or so that I had already paid and previously disputed, I repeatedly asked her for my current invoice. She said I should have gotten it but she would "look into it and get back to me" As you can probably guess by now, that didn't happen either. I had to call her again to request it be sent again AND ask her about the permit Randy said he would get. I had to ask because by this time I was fed up and hired a new plumber. This is where the story takes a nice turn. I have never done a renovation before and it would have been nice to be told that I needed to have an inspection done by the city. I am guessing he didn't mention it because he never got the permits they told me they would. When I called him out on this to Dawn she gave me some lame story about how she rubs elbows with the people that work for the city and its "actually not a big deal" She told me worse case scenario I would get a small fine, no big deal. Obviously she doesn't have an attorney because mine assured me that was NOT the case. Moving along, she LIED to me AGAIN on the phone and said Randy just took care of it. She asked if I would like to schedule more work and I said no thank you. After having a quality plumber look at Randy's crappy work he rolled his eyes and said "this is not good" The main stack had been hacked so many times it looked like a kid took 50 pieces of random pipe and glued them together. After telling the new plumber what I was doing in the bathroom he said he has know idea wtf Randy's plan was but he would have to redo all his work. This included replacing the stack again and properly roughing in the bathroom with the rest of the work I needed finished. He pointed out pipes glued together crooked and even broken fittings. I wouldn't recommend Randy to work on ANYTHING! Call ANYONE besides R and R Plumbing. I wish I had, it cost me THOUSANDS OF DOLLARS!
