Description of Work: I lost my heat and it was going to be 11 degrees that night so I called 2 other companies that were recommended to me and neither of them would come out until the next day. Luckily I called Oliver and not only did they come out by 7pm and get me heat -but- I got a discount as well.

Description of Work: We took advantage of a general heater maintenance special. | |The technician was on time, friendly and professional. He cleaned our heater and made sure it was functioning properly. We also asked the technician if he could help us identify why two of our rooms are especially cold. We have radiators built into our walls and then covered with metal plates. He only inspected the radiators in the two rooms we thought were cold. One of them he showed us was pretty dirty, and he explained how we could clean it, which should both improve the air quality in that room as well as make the radiator work better. This was great to know, especially how to clean it. It's definitely improved the air quality in that room, and it's possibly a little warmer, too. | |He couldn't tell us for sure why those two rooms are so cold, though, so that was too bad. I suspect we'll have to have someone else out to investigate, because if we have another child and need to use the bedroom, it'll need to be warmed better. | |Nice folks, though, I'd consult them again.

Thank you for choosing Oliver, we appreciate your business and that you took the time to leave us this review. I am pleased to hear that our technician was able to help you with the cold spots and show you how to clean the plates to improve the comfort in those rooms. Although we do our best to address immediate issues such as this during an inspection and maintenance visit, you are correct in the understanding that a more comprehensive solution could be achieved with a consultation from one of our home performance specialists. If you would like to proceed with this, we will be happy to assist you. In the meantime, I am pleased to hear that our initial maintenance visit was beneficial to you, and look forward to caring for your home in the future. Regards, Bernie Sweeney, VP Sales & Marketing

Description of Work: I had a leaky faucet. They didn't even turn it on to see if replacement parts would fix it. He just looked and said you need a new one. (It wasn't even that old). Tried to sell me a 500 faucet...I went with a cheaper model.

Description of Work: I have used Oliver for my air conditioning for years, but never plumbing. The plumber unclogged a drain, 20 minutes of work. Delighted with every aspect of the job except the price. I am not sure what my Angie's List coupon netted me-- I paid $285 for the service. I guess that's what plumbers cost?!

Response from Oliver Heating, Cooling, Plumbing, & Electrical
Thank you for choosing Oliver, we appreciate your business and that you took the time to leave us this review. Thank you also for giving me the opportunity to address your concerns about pricing. The simplest answer is that the cost of any given part is only a fraction of the costs involved with installing a part. Oliver uses a flat rate system that also takes into account the vehicle, gasoline, maintenance, tools, and materials necessary for our plumbers to provide service at your home. In addition to these aspects of the call that you see, we also must account for the professional contributions of our customer service representatives, dispatchers, parts coordinators, and accountants that handle each call as well as the overhead costs of the office building. All parts that we install come with a 2-year part and labor warranty, and we offer 24/7 emergency service with no overtime rates. We do operate on a profit, which is a necessary part of staying in business, but the profits that we earn are a very small portion of the flat rate price. I hope that this clears up the issue of pricing, but if we can be of any further assistance in addressing your concerns, please give us a call. Sincerely, Bernie Sweeney, VP Sales & Marketing

Description of Work: I had two people come by. The first was a furnace guy who couldn't give me an estimate because I needed a plumber. The plumber was fantastic and went over and above the information that was needed to give an accurate estimate. The furnace guy forgot to turn the furnace on when he left. I had cold water the next day. The plumber took notice and turned it on for me. The furnace guy spent a great deal of time trying to sell me a service contract. I was not impressed. I was completely stressed out all day when I was unnecessarily stressed all day worrying about the hot water.

Thank you for the opportunity to provide an estimate on this job. I sincerely apologize that we did not meet your expectations, as our goal is always 100% customer satisfaction. The coupon you referenced provides a $59 credit towards any plumbing service work, and we would be happy to honor that for you for a future need. If, however, you still prefer to receive a refund, you would request that through Angie's List (the site of purchase). If we can assist you in any other way, we will be happy to.

Description of Work: Oliver performed an annual check of our Gas Boiler Heating system. | |Oliver was excellent! My wife and I are first time home buyers and we have never had to deal with or maintain a heating system. I called Oliver to have the system inspected, but also asked to be shown how to use the system. Oliver provided a great price for inspection and was able to fit us in the day after I called. The Tech showed up 30 minutes ahead of schedule and was fantastic. He was very friendly and explained the whole system to me while performing a system inspection. We will definitely use Oliver again in the future!
