The company then quoted me $2200 as the cost to replace it and reiterated that this did not include the $99 that they already charged me. So yes, had I gone with that company, it would have cost me $2300. Armed with this information, I posted pictures and exactly what the "diagnosis" said and asked for emailed quotes...to be clear I said EMAIL only. I then got no less than 10 phone calls saying "please give us a call so we can talk about your situation. Some called more than once. Lakeland Heating and Cooling (Jason) was nothing like that... $1270 flat rate to replace the water heater. Yes, thats how he replied in his email.. as I requested. He came in.. with the water heater... replaced it... and went on his way. Other companies, that followed directions, also came in higher than $2000. I am EXTREMELY satisfied with Jason and Lakeland! High Quality, Tremendous VALUE

Really enjoyed the service provided by Michael…read more Our Furnace is old, granted but he tried to find a solution that would fix it. Ultimately it required a replacement, as the parts are just old. I took in other quotes previously to see what the comparison is and I thought Michaels quotes for really good brand of Carrier was better than some other quotes that I received. He came the next day from when I asked about his service. In/out for the replacement it was a good experience. I thought he ran a good shop, was trustworthy. I previously had him service my AC unit as well. He said it was still fine for now and not to replace just yet. I'll definitely have Michael on speed dial for HVAc

If you're planning a home remodel, I would not recommend hiring them. The quality of their work was very poor. The painting was substandard, deadlines were repeatedly missed, and the project kept getting delayed. On top of that, the owner frequently pulled workers off our project and reassigned them to other jobs, causing long delays, while still expecting payments according to the schedule. My experience was extremely disappointing. If you're looking for a company to remodel your home, I recommend choosing someone else.

DO NOT HIRE. If I could give zero stars, I would. I originally hired Duct Professor to fix my home…read moreAC, and they ended up charging me over $1,300 for six incredibly frustrating visits, a string of misdiagnoses, and unauthorized repairs. The first two technicians they sent spent hours troubleshooting but completely failed to find the issue. Instead of properly diagnosing the system, they installed a non-OEM control board without my knowledge or consent. This unauthorized part risked causing further damage to my electrical system through power fluctuations. When that didn't fix the AC, they guessed the AC contactor was the problem and replaced it twice to no avail. It wasn't until the sixth visit that a senior tech finally came out and identified the actual root cause: a damaged low-voltage power line leading from the AC to the house. This is a fundamental issue that should have been caught on day one. Dealing with a broken AC in the middle of summer is hard enough, but enduring a dragged-out, six-visit ordeal with a newborn baby in the house made their incompetence a complete nightmare. Ultimately, because they left my system compromised, I had to hire an entirely different, independent HVAC company to actually fix the problem. To make matters worse, I sent a detailed email to Duct Professor management outlining these failures and requesting a refund for the misdiagnoses and unauthorized parts. They completely ignored me. No follow-up, no apology, no attempt to make it right. Save your money, your time, and your sanity--look elsewhere.

Looked in furnace cabinet and did a test and said the circuit board was bad. I knew I could buy OEM circuit board for about $80. I asked how much to replace the board he said $761.00. I asked if I could get a discount and that I know the circuit board he could get was under $80 with his discount. He said that was the price. Since it was going to get hot I said ok. He drove to local parts store and came back and installed board in about 10 minutes. BY 9:00 am he was leaving. That means He made almost $700 for an hours work and that includes the travel time. Talked to owner Kraig and asked why so much and he said he has over head and the van they use cost him over $60,000. and there was nothing he could do about the price. That is what they charge for a circuit board replacement. Part and labor is guaranteed for one year. If It breaks I will call them but will not call for anything else in the future. Neighbor came over the next day and said he needs furnace and air conditioner replaced and wanted to know if I knew anyone. I told him I just paid about $700 for one hours work with I guy I used but would not recommend anyone when I just paid about $700 an hours labor. When you gouge you loose and people find out and there goes the business. Place does good work but way overpriced. The part On line was not a used or aftermarket part. It was an OEM replacement part. Where you bought the part at Berkheimer in Arlington hts they sell the part to you for less than what I paid for the item. not 2.5 time that price. Even if part cost $200 you still are making $561.00 for 1 hour of labor which includes the time to travel and get the part. I could argue with you all day but it is not worth it, you overcharge for labor period! All the people that ask me for a referral will know you over charge for labor.
