We met with Bob to discuss installing mini splits. He was knowledgeable, answered ALL our questions…read moreand we never felt rushed or pressured, not to mention the best quote! Everything went according to plan, in fact installation was done sooner than expected. Bob has an AMAZING crew to install! They showed up on time, respectful and professional. They made sure we understood how to use our units and if any questions arise, to give a call. Rain and thunderstorms were scheduled the next day, so they went above and beyond and stayed until the job was complete, 12 hours! I also want to add there was no mess to clean up! My husband and I were so impressed with this whole process! I highly recommend Bob Carlson and his crew. You won't be sorry! We're already inquring about our next project!

I called Carlson heating due to intermittently my oil furnace would not ignite. My oil flow to…read morefurnace was fine. I suspected the ignitor unit was bad. But wanted to be sure. I thought they had a special tester. I was wrong about special tester. Ultimately I could have tested it. But the tech was detailed in his diagnoses and explanation and the Ignitor was replaced. Afterwards I found the price charged me was 3 times retail at H-D. I am a retired electrician. They tried to also sell me the controller that had no issue other than it was old. I said no... because I am an electrician, and I can swap that if needed, it's just a relay unit. Then realized after they quoted me 3 to 4 times retail $ on that item too. The techs are knowledgeable and appreciate their work, but their parts pricing is too much. I recommend them for their knowledge.

Update: This company went from a great experience, to the worst experience. My secondary heat…read moresource went out during the winter and I called for a service checkup. After about 15 minutes of work I was told the condenser had to be replaced due to mice chewing the electrical wires. I could understand this. Here is where the issue comes in. The technician first said it would be $3400 to replace. He then went to his truck and came back to tell my wife it would actually be $8,000, but they added a discount so I would Pay $6,000. The total cost of the whole install (condenser unit + 4 wall units) was 12,000. So just to replace the condenser is over half the cost of the initial install. I called to complain and spoke with the service manager. The service manager essentially explained to me that this was accurate because if they did the install today it would be 23,000. So they evidently had a 100% price increase. I then explained the invoice showed the unit itself as 2,000 and then labor as 6,000. He explained to me that was untrue, that due to the new invoice system they have, they can just put numbers anywhere essentially, so I should ignore the invoice. I explained my frustration and how that does not make any sense and I am not paying 6,000 for a condenser and labor. He said he understood and would escalate it higher and I would get a call later that day or the next. It's going on 3 days now and I have not heard back. This company went from one of my top rated to near highway robbery. I cannot reccomend them to anyone at this point, and will need to look into alternatives to get my heat back in the winter.

I used to use them for my yearly services, called the 24 hour line at 6 P.M. because my hot water…read moreheater went and basement flooded. The guy who answered the phone gave me the voice like he just woke up and or was stoned, didn't want to be bothered, was rude not helpful at all.

Just before the New Year this past winter we had Call the Bee (a plumbing company we'd used in the…read morepast) come out for a whole house main drain clog. We received a call back right away and they sent out a technician that afternoon. He was clean, courteous & upfront about the plan to clear the clog and the companies pricing. After the snake didn't clear the clog he used a camera and then a water jet to clear our line. Unfortunately the problem returned very shortly after and having lost faith that Call The Bee was able to fix our problem we called another local company. They came out same day, cleared the line and charged approximately the same price. Feeling like we shouldn't have had to have another technician out so soon and incur another charge, we reached out to Call The Bee and spoke with them. Yes, we should have given them a chance to fix the problem instead of calling another company but as I stated, we'd lost faith in them. But, we , I, was wrong. They (Call The Bee) were more than responsive to our problem. Took the time to hear us and wanted the invoice from the second company we called. Lo and behold one week later a check for the ENTIRE amount of our second plumber (slightly over $1,000) was sent to us. Call the Bee truly did all they could to rectify the situation and leave us as satisfied customers.

After seeing their exceptional work at another facility, I contacted Charter Oak Mechanical to…read morereplace my AC compressor with a heat pump. Although my furnace was ok, it was old and I decided to replace it also. Their price was reasonable. Although, the owner, Steve, said the job might go to two days, Robbie and his crew arrived on time, and got right to work with the replacement. They completed all of the work on testing, and set up the new equipment on my Nest thermostat. They cleaned up completely, and walked me through all of the new equipment. All said, they did the best job I could ask for. In the office, Julie ably worked out the schedule, invoices, and rebates available for the equipment I was purchasing. I will be pleased to continue using Charter Oak for any ongoing maintenance, if any is required.
