The team at Metro Heating and Cooling was able to bring someone over to diagnose the issue, then bring a team over and complete the install of a new furnace within one day, working until after 7 pm because they said they were not going to leave us without heat for a night. We are extremely grateful to their team and will definitely be going back to them for any future work we need!

Nobody really likes having to replace a furnace, but Groff helped us out and made the whole process…read morerelatively painless. Came out for an estimate, and of the four companies that gave us quotes, Groff offered the best price for the best furnace and the quickest timeline. A few days later, they came back for installation. It took about 4-5 hours including complete set up, removal of the old furnace, and some quick paperwork for a rebate. Everyone was friendly, professional, and clean. The new one works like a charm and our house is warm again. Hopefully we'll never need them for another furnace as long as we live in the home, but would use them again if needed and recommend to others.

We looked around and read many reviews. We decided to contact Twin Cities Furnace Cleaning. They did not answer the phone right away but I received a call very quickly. I explained the situation and how we have some allergies, and they took the time to listen and go over all the details. They then recommended Steve who is the go-to guy when it comes to allergies as well as other things related. We set up an appointment with Steve, and Steve arrived early. He set up his equipment and was very mindful about making a mess as well as getting things dirty and wet. He took his time to explain as well as show me what was going on and answer all my questions. Because of allergies Steve took his time and made sure each vent was cleaned as best as possible. The things I saw in the ductwork were scary, which had built up over the years of this property. After he was done, we swapped the air filter and within 20 minutes of running, I could smell the difference in the air. The air felt lighter and did not have a heavy feel. Also, my air purifiers were not reading off the charts anymore. Steve did a fantastic job and I would highly recommend him as well as Twin Cities Furnace Cleaning. I ended up getting their Ultimate cleaning or whatever the highest one was, and compared to other places, it was cheap. The price you pay for what you get is a bargain. It ended up being $541.00 with tax and worth every penny.

BEWARE: Independent contractors are used by this company who carry their own insurance. I had an…read moreunfortunate situation where a furnace drain hose was bumped out of place by one of this company's independent contractors causing a leak in my ceiling weeks before my house was to close to a new owner. My claim was declined. The insurance company required unrealistic things like a photo of the space prior to incident showing the hose in place. Who takes pictures of their furnace? This resulted in a costly last-minute repair to my ceiling. Essentially this means that you are at the mercy of a potential crappy insurance policy carried by the contractor and that the owner takes no personal responsibility for potential damage.

UPDATE (July 9, 2025): After posting the review below, the…read morebusiness owner escalated the situation by leaving a 1-star Google review on the page of my employer -- a completely unrelated business. In that review, he made false claims about my conduct and advised others not to hire me. I have never contacted this person outside of leaving public reviews, and I have blocked all further contact. This action appears retaliatory and inappropriate. I have reported it to the Better Business Bureau, the Minnesota Attorney General's Office, and the FTC. I stand by the review below, which reflects my honest experience as a prospective customer. [Updated to address owner's response and clarify timeline.] I reached out to this business via their website to get the air ducts cleaned in my duplex. After submitting their contact form, I was quickly texted and asked to send pictures and videos of both furnaces, which I did promptly and completely. They confirmed receipt and said they'd send a prep list, then communication abruptly stopped. Over 25 hours passed with no follow-up, so I sent a text asking for an update. I received no reply. At that point, I reasonably concluded they were no longer interested and chose to leave a review to reflect my experience. Immediately as I was submitting the review, I received a phone call from them -- too late, as I had already hired someone else. I did not answer. They then sent a text acknowledging they had just seen my follow-up. Rather than take responsibility, the business replied to my review publicly and posted my full legal name (including my middle name) -- which does not appear on my public Google profile and which I never gave them permission to share. This is a clear privacy violation and feels like retaliation. They also imply that I'm unreasonable or dishonest by telling others to "click my name and see the type of reviews he leaves." I welcome anyone to do so -- over half my reviews are positive 5-star feedback, and any criticism I've posted is respectful and factual. This kind of response is unprofessional and borders on gaslighting. This review reflects my honest experience: I was responsive, patient, and gave them a fair chance. The poor communication and inappropriate public reply speak for themselves.
