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.
