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.

After a month of back-and-forth with Trane and the contractor who had been maintaining my central…read moreair for over ten years, I was getting desperate. The previous contractor said I needed to replace the condenser which couldn't be repaired. I decided to get another opinion and called Ryan F Murphy the Friday before Memorial Day Weekend. Christina was very understanding, and first thing Tuesday morning I was pleased to hear from Ryan, who, instead of just quoting me for a new condenser, told me he would be coming by that same morning to see the unit for himself instead of going by someone else's explanation. A couple of hours later, he was here, determined the problem was easily fixable, explained he was "90% certain" it could be fixed (very clear in his explanation), and that one particular part wasn't on his truck. Five hours later, Jimmy was here, and in minutes replaced the part and... eureka! We've got air conditioning again. Jimmy then checked over the system to see if there were any further issues. And to top it all off - not only are they nice people, but the price was fair (even including after-hours service) - and disclosed in advance. Ryan, Jimmy, Christina, you have a new customer - and a new fan.
