“They did a home inspection of our electrical system and looked at possible repairs. We have a maintenance contract with them as well. I get the feeling they're honest, so we trust them, because I don't know the first thing about HVAC or electrical. They call, they show up when they're supposed to show up, and they do their job. And it has worked; they haven't had to come back. They deserve an A.”

I wish I could clone them for my other services. They come out when they say they're going to. If you call, they're there.”

“Outstanding. They did some electrical work for us several months ago that was really terrific, and we're really pleased with that. They fixed a light on the outside garage, they added some lighting in a large closet, and they added two light fixtures and had to pull all the wiring for that. And then they also added two floor receptacles. From an electrical standpoint, everything has gone well. I couldn't be more pleased.”

“Oliver did one small job for me. The electrician was in and out. He came in, took a fan out, and that was it. It was a job I had to have done right away, and they were accommodating. I haven't had to call them back. I'd probably give them an A.”

“Oliver has done it all for us—heating, air, and electrical work. They've never let me down or given me a reason to make them come back. They get an A.”

They get an A; I'd give them an A, definitely.”

“I'm very happy with any service Oliver's done for me. We had three projects in the past year—water heater, electrical, and plumbing. My overall impression of these guys is positive. The people who come out are very courteous, do their job, do it well, and clean up after themselves, so I never have to worry about that. I would give them an A, no problem. I recommend them all the time.”

“They installed an attic exhaust fan, and then they put a new ceiling fan in one room that didn't have one. They came back the following week and redid my electric service panel and put in a whole-house surge protector. Their quality of work was excellent. They were top-notch—I wouldn't have had them back the second week if they hadn't been. There were two of them the first week, and one of them came back the second time to do the electric panel. They were very professional; they cleaned up nicely after they were finished, and they told me what they were doing and answered my endless questions. I've recommended them actually to my neighbors. I wouldn't hesitate to recommend them to anyone. They're an A.”

“It went perfect, flawlessly. They did was electrical work; we had to move some light switches and some outlets. I haven't had to call them back to fix anything.”

“Everything went extremely well with Oliver. I like that they're prompt in getting scheduling, they arrive on time, and they take the time to carefully do the job. There's a high degree of quality, and I have a lot of confidence in them. They've done electrical, and they're the primary contractor for my maintenance contract on my boiler. In both of these fields, it has always been universally great; I'd give them an A+.”

“Oliver was fine. They did electrical work for me. I had a renovation—an addition to the basement—and they did all the electrical work. It was a positive experience overall. They just were good. They came in, they knew what to do, they were very friendly, and they were very helpful. I'd say they deserve an A+; they were good.”

“Overall, I had a positive experience with Oliver, very much so. They did a great job. They're very courteous. We had some electrical work done with them as well. For the air conditioning service, they came in and just checked the condensing unit to make sure that was running properly. They cleaned out some kind of drainage pipe down in the basement for the A/C unit. They performed a preventative maintenance. For the electrical service, we got an entire new electric service put in outside—new meter box, new breaker box—and that went great. The electrician was here before; we had a minor electrical problem which he fixed, and then the same electrician came back to put in new service. He did a great job and was very courteous. He just did a great job. Everything is holding up great. We have a service contract now with the A/C and the heat, and also for the electrical service now. I would give them an A, absolutely.”

“They've done work for me in the past. First of all, all of the people that do come to the house are dressed appropriately and are well-groomed; you feel comfortable with them. That's the important thing. I do feel comfortable when the workmen come to the house. Their quality of work is excellent. I'm very pleased; everything about them is excellent, and I've been with them since 2005. They're an A.”

“They're good. They're a good company. They do good work and we've had them for years. Their professionalism and their response to emergencies stands out. They have good customer service when they come out, they finish the work in a reasonable amount of time, and they clean up after themselves as well. They're an A. I would recommend them to someone else.”

“They were terrific. You just call and arrange for an estimate and a review of what the need was. We had them put in a whole house generator. The customer service was excellent, but there really wasn't much of a challenge to that. They were very polite, very friendly, and they made follow-up calls. I thought it was excellent, but I didn't have to really use a service department. It was their insulation people. They were incredibly prompt. They were there within five minutes of when they were supposed to arrive, to either give us an estimate or to do the installation. They cleaned up after themselves. I would say A, excellent. I absolutely would use that company again, and I would recommend it to friends.”

“We just have routine maintenance for the heating and air conditioning. They always seem to do a pretty good job, they seem to be on time, and they have some knowledgeable people. I'd say I would give them an A, I guess. I've always been pretty pleased with them.”

“They diagnosed the problem and repaired it. Everything went fine; they responded quickly, they identified the problem quickly, ordered the part, and replaced it within a reasonable period of time. I had no problems, no complaints with them. I'd give them an A.”
