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 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.

When I call for a refill they are always friendly, and the deliveries are prompt. Recently we had them replace one of our HVAC compressors. Their estimate and replacement was incredibly quick, especially since we were in the heat of summer. The sales agent even came to the house a couple of times to manage the contract particulars. I would recommend them to anyone; their service is lightyears ahead of most companies. 5 stars in my book!

The representative Dave came to my home of record provide me with a quote and signed a contract to enter into services. Instead of taking my business, they completely refused to provide service valid reason explanation or alternatives.

If they are this dismissive to new, paying customers, I do not recommend relying on them. Take your business elsewhere. This was zero risk transaction for them, they claim to be a family run business but decline to service my family! Deed not Words.

They were able to come out within two days, while every other company I contacted quoted two to three weeks just to get an appointment. The person I spoke with on the phone was incredibly kind and understanding. They kept me informed, called to let me know the technician was on the way, and even texted me a photo of the technician beforehand, which I really appreciated for safety and peace of mind. The technician who arrived was very nice, professional, and extremely helpful. The entire experience was smooth and stress-free. Since the visit, my furnace has been running quietly with no more strange noises. Best of all, the maintenance service was under $200, which felt very reasonable given the quick response and quality of service. I'm so grateful they were able to help on such short notice and would absolutely recommend them.

If you're an average parent like me with minimal plumbing knowledge, and want to be overcharged and…read morehave to spend the next couple of months paying off the extra cost of a service that should've been 60% cheaper...go with this company. We had what I now learned from a non-local family friend was a simple backflow preventer failure. The friend ball parked it around $500-600 max, and that was with up to 2 hours of time taken. This company charged me $1300 for an hour of time with a single part being replaced. Similar parts are available online for $150 (and I assume they get parts even cheaper). My family is leaving town this weekend and I wanted to ensure this got fixed (but it was not an emergency call), so I didn't take time to vet out other contractors. I regret that, and have learned my lesson. Thanks F.F. Hitchcock. The Tech who visited was professional / explained things well. I'm not sure who sets the price, so if he had nothing to do with it, then this feedback should strictly go against F.F. Hitchcock's pricing structure. I reached out to F.F. Hitchcock a couple of hours after the service was performed, but so far have not received a response 2 days later. Do yourself a favor, find another company to service your plumbing / hvac.

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.

Based on my experience with them on two occasions, I would give them a 5 star rating…read more Bosse Heating and Air Conditioning was recommended to me for my annual oil burner service. It had been about 3 years or so since I had the last service done by an oil company I no longer use. I called Bosse, created an appointment on a Saturday (WOW - those appointments usually get filled quick!) and waited for the day to arrive. They were scheduled to arrive between 8:00 a.m. and 10:00 a.m. They arrived around 8:30 which was perfect. On time. :-) He spent a good portion of the time just vacuuming out all the soot, etc. since it had been so long since I had it cleaned. (Yes, MY fault.) He then replaced the filter, the nozzle, etc and took a final efficiency reading (82% - which is great!) Price was reasonable and I was extremely happy that he took the time to clean it correctly, even though it was my fault it was so dirty. I tried to give him a tip for putting him through that but he wouldn't accept it. So I thought that would be the end of it until next year, when I will hire them to clean it again. I was wrong. Two days later I was doing my monthly sump pump testing (in the same area as the boiler) by filing the sump pit with water from a hose attached to the Amtrol Water Tank Bladder. Well, I opened up the valve too quickly and the water pressure whipped the hose out of the sump pit and it liberally soaked the entire boiler before I could get it shut off (and we're only talking about 2 seconds here). The water must have fried the electronics (the relay unit) because the boiler stopped working. I shut off power, removed the unit and dried as much of it off as I could but it didn't work. My boiler was down for the count. I called Bosse again and explained the situation. They told me that they are super busy and backed up with service calls because winter is approaching. But they would try to get someone out to look at it. About 2 hours later she called back and said they were still looking. Ten minutes later their truck pulled into my driveway! Woo Hoo! They came in and diagnosed it as a bad relay unit due to "water damage" i.e. my fault. We had a chuckle about that and he promptly replaced the unit. All is fine again and the boiler is working perfectly again. And I vowed to never try to wash and wax my boiler again! So two thumbs up to Bosse!
