On July 7th we had Blount come and do some repairs to our furnace pending the sale of our house…read more Tech came to the house and my husband asked if he needed to stick around while he worked on the furnace and service tech said no. On July 13th I come home to a Blount business card on our door asking to call them. I also talked to my real estate agent and she said Blount left her a message and the buyers real estate agent saying were not paying our bill. She forwarded me the voicemail. I reached out to Blount on July 13th and left a message with their answering service and spoke to them on July 14th. They said their service tech waited around our house for 40 minutes expecting to get paid for his service on the 7th. #1 it was never relayed that their service was COD. #2 it was never relayed to my husband on the day of the service how much was owed. We would have paid on the 7th if we were informed of that. Blount said they called the phone # they had on file for us and it was disconnected. We have had them done work for us in the past and they had our landline on file that has been disconnected for years. I called and made this appointment and provided my cell # and I emailed them a couple of times regarding this appointment. It's not my fault they are not updating their records with my current contact information. They had NO RIGHT to call and tell our real estate agent and the buyers agent telling them we are not paying our bill. I will not recommend them. If they think it's ok to do this type of business practice, no one should be doing business with them

Customer Review - 2022…read more Christensen & Wisnet, Inc. - The Good Guys Heating and Air Conditioning 4450 W Greenville Dr Appleton WI 54913 https://goodguyswi.com (920) 734-1436 In May 2022 my air condition from the early 1990s was no longer going to work and I knew the original 1950s furnace and 12-year-old water heater need to be replaced. I was very unhappy with our old service company. I research the best rated Heating and Cooling companies and called the top 4 companies. Anthony from the Good Guys was the only one to get back to me within a week to give me an estimate, he was there the next day! After getting the other 3 estimates his estimate was still the best for price, quality, and the service they would provide. They were also the only company that would get my new system installed in June! Homes come with all sorts of Heating and Cooling systems, and they date back to all sorts of dates. The Good Guy team knew how to assess my old system and were able to find the best products and installation for me. In fact, they first solved a duct work installation issue by worked with most the old duct work avoiding extra costs. Later when it was time to install my new heating system Anthony called be back with a better more energy efficient heating product saving me a few thousand dollars and also giving me a $500. Rebate! I must say what I was most impressed with was the service of the whole team. I loved working with them, they are the best service team I have ever had in my home! Each member of the team was great! They are very prompt, friendly, knowledgeable, experienced and the results have been fantastic - everything works well. It I ever have a question, need a follow up or just need someone who listens and finds a solution for me they are there, always with friendly professional service. Use them! Cheers! Thank You Good Guys! J,S. Moore Menasha, WI

My elderly mother in law was being taken down the con lane by KKomfort and they wanted to price gouge her and do repairs that her boiler did not need. She is elderly and on a fixed income. My husband insisted that she let these folks give her a second opinion. They came in a timely manner, behaved as professionals, and took care of her boiler for a reasonable fee and did not see any of the issues KKomfort claimed she had and wanted to charge her an exorbitant fee! KKomfort made a fake diagnosis on her system! Thank goodness for Christensen and Wisnet! We will use no one else! Go with a long held reputation for great, honest service! Don't be taken for a ride by someone who wants to con you and over charge you!

We had them out last year for a tune up with no issues, but this year when they came out they charged us an extra $50 for a "trip charge" after the service was done that no one told us about prior. I called and asked why I was getting this and they told me "every other heating company charges this now" but I called around and none of the other local companies do. The other issue I had was that they came out for the tune up on 12/15 and our payment didn't pull from our debit card until 2/2. When I called to ask why they didn't pull the payment for 6 weeks the guy blamed it on our debit card which is false. Someone there messed up and didn't run the payment right away. I would probably still use them if there had been any sort of apology for not telling us about the trip charge and waiting so long to run the payment but the guy I spoke to just kept trying to pass the blame and didn't offer any sort of apology. Terrible customer service and shady business practices.

I live at Richmond Terrace and had a furnace/air conditioner replaced by Bob's Heating. This was a…read more$7000-$8000 installation. Afterwards, I had concerns about how to properly clean the grate, as there was no accessible panel. A representative from Bob's confirmed that the grates are not removable and advised using a product called Nu-Calgon Evap Foam No Rinse to clean the condensing coil. Earlier this year, Matthew's Heating & Cooling inspected and cleaned my furnace. They determined that the condensate drain had not been installed in a workmanlike manner and strongly advised against using the cleaning product mentioned above (see attached report). To date, we have identified at least two furnaces that experienced this same issue. I scheduled a meeting with the condo board president and a representative from Bob's Heating. No one from Bob's showed up for the meeting. I would urge any resident living at Richmond Terrace to use another vendor when replacing their furnace.

They were professional, skilled, and had the the new system installed in the basement in very little time and it worked perfectly. A few years later the starter in it did burn out and their 24 hour emergency service person was prompt and had the part needed. The other day we thought we smelled gas in a small wall heater that is in our porch so we called them; they came right out to check. Turns out there was no leak (they did a thorough check) so we were happy about that. They also replaced our heating/ac unit's filter. Very professional, helpful, answered questions/concerns. I recommend Modern to anyone who is in the market for installation or service of HVAC.

First of all....they're awesome. We moved to the area in 1998 and added a/c soon afterwards…read more There was a Modern Sheet Metal sticker on the furnace, so I called them for an estimate. We haven't used anyone else, nor quoted anyone else since then. This past weekend I noticed an odd smell and soot buildup on the exhaust vent for our furnace. Since it was a Sunday in February, I called WE Energies first. The WE rep measured the CO2 at the exhaust and told me that he would need to shut our furnace down before he left, and recommended that I call my HVAC contractor. Modern Sheet Metal had someone at our house within a half an hour. He told me which furnace he would recommend and measured for the new unit. Since it was a Sunday, we scheduled the install for Tuesday. He then left three space heaters with us to keep the house warm. Monday morning's temp was 15 degrees outside, 64 inside. As I was preparing to leave for work at 7am, my phone rang. It was Modern asking if it would be okay to install the new unit that morning. The guys arrived before 7:30 and had the new furnace installed by 10:00. They also left the work area cleaner than when they arrived. Absolutely recommend them for your heating and A/C needs.
