“It was absolutely positive. The gentleman that came was very polite. He did his review of everything. He explained everything to me, which what do I know about heaters and air conditioners? He did it, and he went along. He was explaining everything to me and told me what he could do to repair. My heater needed a couple of things and my air conditioner. Then, he gave me options. My heater was fine. He just had to do a couple of things to that. My air conditioner is not in that good shape, but even so, he said that he could fix it for the time being. I'm thinking of moving, so I don't really want to have to put a new one in if I don't have to. It'll be years before I move, so in the meantime, maybe I will have to replace it. He didn't think I had to do that at this time, just the heater and the air conditioner. I would give them an A, and I would certainly call them again if I needed to.”

“The guy that came, he was very professional and did everything he was supposed to do. I didn't have any issues. The line was clogged from the vine thrown into the sewer pipe. I've used Donnelly's before. I think Donnelly's did some heating work for me once. They came out and gave me a quote because I needed a new air conditioning unit, but their quote was kind of high. I'd give them a B. The plumbing is expensive regardless, but I think it was fair.”

“They did a good job, were clean, and cleaned up. They knew what they were doing. It really didn't cost that much. They fixed three sinks. I know they fixed a sink on the second floor, first floor, and cellar. They were here last September to tune up my heater. I'd give them an A. I don't remember if we had an appointment or I said come over when you have a chance. I already have recommended them.”

“I always have a positive experience with Donnelly's. I've used them since 2003. This is the second hot water heater they've done for me. One was when we bought the house. They put in gas lines, faucets, a garbage disposal. They've maintained the furnace for our radiator. I have no reason not to give them an A+.”

“They came on time. They were honest with what they did, and didn't seem to want to charge me for stuff that wasn't needed. They just did the regular heater inspection in the fall and air conditioning in the summer. They just did the regular inspection, new house. I'd give them an A for the overall experience.”

“They haven't done work in quite some time. It was in March, the service. It was fine. They did the work. I think what they did was by mistake. I turned it on the wrong way, and the fuse burned out and they had to come shut off the fuse. It's for my heating and air conditioning. I'd give them a B.”

“I've been dealing with them for years. Whenever I've needed anything, especially if I’ve been in an emergency situation, they've always been very prompt. They're very knowledgeable also. They've done a complete overhaul of my HVAC system and water system. It was a pretty big job. They're A+.”

“They're prompt, clean, and courteous. Donnelly’s Plumbing know what they're doing. They put a new hot water heater in. We've used them several times in the past and we highly recommend them to our fans. They do heating/air conditioning work for us. They've basically done it all. They're A+.”

“They were supposed to call me. They're supposed to call me back and set up a time to come look at my HVAC. They called and I wasn't home so I said give me a call. It's not Thursday yet. They've done a hot water heater and serviced my gas heater for the house. I'll give them a B+.”

“They did what they said they were going to do. They came when they said they were going to come, and it cost me what they told me it was going to cost. They do an annual kind of service on my heating and my air conditioning. That was my first time. I would say A+.”

“They were all very responsive if you need help. He always returned the call quickly. Donnelly’s Plumbing always guarantees their work too. They've done plumbing, heating, and cooling. They replaced the system for me and they've also repaired. I'll give them a B+.”

“I thought it was a bit expensive, but there's nothing I can do about that. It was just a flame sensor that was bad. It was heating work. I would give them a B. They fixed the problem. The work was fine. I probably wouldn't recommend them.”

“Everything was fine. Travis came and figured out that the air conditioning unit didn't work because a mouse ate all the wires. They come when they say. They let me know. I haven't had any issues at all with them. I'd give them an A.”

“He was very pleasant, the young man who came, Shane. They were very efficient. They did a good job. I even recommended them to one of our sons. They fixed our furnace. This was our first time. They get an A+.”

“It was great. They were on time and the guy did a nice job. He was in and out pretty quick. He fixed the toilet. They've done heating and air in the past. They put a hot water heater in. I'd give them an A+.”

“Donnelly’s Plumbing came when they said they would, and they did what they said they were going to do. They checked the air conditioner and the heater. We've used them a few times. I'd give them an A.”

“We have moved to California. I have had a very positive experience with them when I'd used them in the past. They replaced our entire HVAC unit. I would give them an A+.”

“I think I signed off for their program, but I haven't heard anything. They showed up, and they did a good job. They did heating. They repaired it. I'd give them an A.”

“They've been great. They're on time. They do quality work and the prices are good. They've done work fixing our heating and air conditioner. I'd give them an A.”

“We love them. They put in two new HVAC systems. This is the second time we've used them. They're reliable, and they had a payment plan. I'd give them an A.”

“Overall, the whole experience was good. They did some heating repair. I'd give them an A, excellent.”

“They were clean and professional. I'd give them an A+.”

“I'd give them an A+, and they did my air conditioner.”

“They did what they came out to do. They looked at my air conditioning unit, general maintenance. I would grade them a B+.”

“They were prompt and the pricing was fair. There was an electrical issue on the outside unit. I'd give them an A+.”

“They were on time, they did a fair job, and they went over everything before they did the work. I'd give them an A overall.”

“They were fine. I'd give them an A+ overall.”

“It was great, no problems.”

“It's the second or third time we've had them. They're dependable. I think their punctuality and the quality of work stands out. Overall, I'd give them an A. I'd recommend them highly.”

“The experience with them was fine, but the experience with the product was not. We spent a lot of money on a new furnace and to have to pay $12 on a repair within three years is ridiculous. Overall, I'd give them a B.”

“They installed a heater and an air conditioner. I'd give them an A for the total experience. I've used them before so I would recommend them since this is not the first time they've worked for me.”

“We used the company for the HVAC unit. They showed up on time and they were really informative. They actually told us what caused the problem and how to prevent it from happening. It was excellent with no complaints.”

“Our air conditioning had a problem. They were professional and clean. They explained what they had to do and why. It's sort of a work in progress. We need to revisit it in a few months. I'd give them an A overall. Their customer service was very good.”

“They replaced the air conditioning unit. They were quick, we didn't have to wait too long. It was good but it was expensive. They were fine. I'd give them an A overall.”

“I used them for my water heater. It's fine, it's replaced. I'd give them an A overall.”

“It was excellent. They were great. I would highly recommend them.”

“It was excellent with no complaints. They did HVAC work.”

“My toilet's still leaking so that part's not so great. I've used them for several years so it's mostly good, but the toilet thing is annoying me. I've used them for plumbing and air conditioning. They're fast. I'd give them a B overall. They could've fixed my toilet to get a better rating from me. I haven't talked to them. I said, 'Fix the valve'. He said he could just switch the part and it'll fix it. He just switched that part and it didn't fix it because it doesn't. You need to pull out the whole valve and replace it. I could do it myself and I didn't last time because I didn't have time to go to Lowes, get the valve, bring it here, and all that. So I said I'd just pay them to do it and he didn't do it. He argued with me about doing it and now it's still not fixed. So now I don't know. Do I go to Lowes and do it myself or do I call them back and make them do it again and argue with them about how they didn't fix it the first time? All of the other stuff, they were good. The fact that it's still leaking and I told him what he had to do to fix it and he disliked my idea and did his thing.”

“We had a new heater and air conditioner put in. I liked the salesperson. He was very upfront. When we called to complain about something, they were very quick to come and straighten it out. They were good but with a slight issue, a B overall. They were very clean, they cleaned up all of their mess.”

“I had an issue with an A/C unit that was not working properly. They were able to fix it for me. The most important thing is that they knew what was causing the problem, so their knowledge was very good and they offered good advice. Overall, I'd give them a B. I thought they spent too much time talking on site, too much banter. I like to talk, but it just seemed like it went on and on when it didn't need to.”

“I've been quite happy with them. They did everything having to do with our heating and air conditioner. They replaced the heater and air conditioner shortly after we moved in, replaced the water heater when the water dropped out and it dropped water all over the basement, and general maintenance on stuff since then. They show up when they're supposed to and they do a good job. I'd give them an A+.”

“It was a very positive experience. They replaced a heater, air conditioner in my house. Their prices were reasonable. Their guys were in and out in one day. They kept my house very clean and they took extra precaution to make sure they didn't drag dirt all over this house, which I really appreciated. They were just excellent. I'd give them an A for the overall experience. These guys were great. I thought they were just wonderful.”

“The gentleman that came out was very nice. They didn’t solve my problem. It was air conditioning and after I spent eight hundred and some dollars it still was not fixed. I was told I needed a whole new air conditioner after I spent all of the money. I was really not happy with it. The guy that came out was very nice and very polite. If I was told that no matter what they do, it's not going to fix it and save me the money. It's a negative experience. I'd give them a D overall because it wasn't fixed and knowing they couldn't fix it, I don't think they should've done what they did and still charged me for it. They came back and then said, 'We'll give you your money back, but you've got to buy the air conditioner unit through us.' Customer service, he was really nice.”

“It was positive until recently. I wasn't happy. Everything was done fine until I just had a problem which should have been picked up in their prior work. Basically, they were called because I have an air conditioner in the attic. The condensation pan had overflowed, and it flooded the ceiling and drywall. I had water dripping into my son's room from that—water dripping from the ceiling. They came. They went. They told me all the issues. They fixed the pan. They said it had been rigged before. They cleaned it out and did it and assured me they had resolved the problem. I looked at what I could up in the attic, and it all looked good. I didn't have a problem until we just had the power go out with the storm about three weeks ago now. When the power came back on and the air conditioning came back on, I woke up in the morning, walked out to my hall, and I'm in about three inches of water. The same thing had occurred again, and this time, it had flooded my hallway and ceiling. Eventually, within two days later, the drywall of the ceiling actually fell in and almost hit my son's head when he was walking by. So, of course I wasn't going to get them because even though they had done it right, I'm not relying on them again.”

“It doesn't take long to get them to come out—that's one of the really good things about them. I’ve been using them for two years for air conditioning maintenance, and I would give them an A+ rating.”

“Everything went very, very well. Donnelly's Plumbing, Heating, & Cooling came as soon as possible, found out what was wrong with my air conditioning, and then took care of it. It had something to do with the motor. Everything was fine—I’d grade the work as an A.”

“Donnelly's put my HVAC system in. They do my air conditioning, and they’ve fixed my heating system. They're pretty prompt, and I like their service. I've been using them for the last three or five years. They deserve an A+ grade.”

“They serviced my heater when it stopped working. They were good. What made them a good company to work with was that they came right out when I called them—only an hour and a half after I reached out. The issue was the igniting coil; the burners needed to be replaced. They did a grade-A repair.”

“Donnelly's was quick, and the guy really knew what he was doing. It was a brand-new house, so the A/C wasn't working at all. He diagnosed it, and in ten minutes, he got everything fixed and left. We chose them because they were who our builders recommended. They do A+ work.”

“I had an awesome experience with Donnelly’s. My thermostat wasn’t working, and my heat wasn’t coming on. They came out within an hour, and they were done within half an hour. When the guy came out to my house, he kept me informed, and I really liked that. They’re an A+.”

“I had a no-heat situation. I called Donnelly's toward the end of the day, and they had somebody there that evening. The problem reoccurred the following day because we had a snowstorm, but the guy who had come out and worked on the problem the night before spent about a half hour to 45 minutes on the phone with me. He walked me through solving the problem because there was no way he was going to be able to get here—we'd had about 10 inches of snow, and he was about 45 minutes away. The first thing I liked was him coming out and addressing the problem, and then when it didn't work entirely right, he spent time with me on the phone the next day so I could fix it. I chose them because when I looked for emergency service from HVAC companies in my area, the other place I called didn't get back to me. When you call Donnelly’s off hours, you get an answering service, and they try to reach the technician. I explained the problem to the answering service and got a call from the technician within 15 to 20 minutes. He told me he'd be right down to take care of the problem. The quick turnaround—from the phone call, the quick service, and everything—makes them an A+ company.”

“Donnelly Plumbing & HVAC did work for me back in April. The gentleman who came out seemed competent and was polite. They serviced our air conditioning units. It was just regular maintenance. They've been servicing us for two years now. I'll give them a B+. I think the guy– he came out and went up into our attic where the conditioning unit was. He could have done a better job but I think he was fine. I would still recommend them.”

“I liked that they did not talk down to me. They explained what it was they were doing and why they were doing it so that I understood what was going on without talking to me like I'm a girl who doesn't need to have it explained. They repaired the heater, and they were quick and efficient about it. We've got radiant heat, and it was making all kinds of weird, banging water noises. They came in and bled air out of the line. I chose them because I had called a different company, which gave me an outrageous estimate. Donnelly's did an A+ job.”

“Donnelly Plumbing were prompt. Their prices were competitive. They were able to work around my schedule. I bought the house and there was a backed up sewage line. They installed a new heater; that was all last summer. Just recently they fixed a basement sink. I chose them because the plumbing was convenient. When it's plumbing you want who can come out the fastest. They were the least condescending and most competitively priced of the larger firms for the HVAC. I'd give them an A or A-.”

“Donnelly Plumbing & HVAC were on time. They had good service and a good attitude. I believe the work they did for me involved the air conditioning. I've been using them for a while for my maintenance– I'd say maybe three or four years. I would give them a B+. The problem shouldn't have occurred in the first place and I'm not sure why it did. It's a bit of a mystery to me. I'd still recommend them.”

“Donnelly Plumbing & HVAC put in a new heater for us. They were fine. It was pricey but everything works fine. They did a good job. The service people were great. They were very responsive. They just got down there and did their work and they were gone. I chose them because I had an emergency. I probably paid a little more than I should have but that's what it was. I'd give them an A on the service.”

“Donnelly Plumbing & HVAC did a good job. The men are really great. They were really efficient and helpful. They came to check my– in fact we ended up getting a new water heater. I've always chosen Donnelly Plumbing & HVAC for a very long time. I just went back to where I normally go. They're a very good B.”

“Donnelly's was good. We had them do service for the heating system, and it was OK. There were no problems, and it's working well.”

“When I call, Donnelly's comes. I've used them on a number of occasions. They've done my air conditioning and fixed the toilets. I chose them because I wanted somebody right away. They get an A.”

“They put a gas boiler in for me, and it went well. They came out on a Sunday, and they were just good guys.”
