Hvac Reviews in Saint Paul


, the salesperson we worked with, was very patient with all of our questions and we never felt that he was trying to sell us more than we wanted. In fact, he talked us back from a higher end model at one point and did a great job making us feel comfortable with our purchase.
We have an older home and went with high efficiency units, which really forces the installers to get creative to make everything fit.
, Pat, and
spent a couple of days cutting out the old unit and working the new one into place. The installation team was great, they answered my questions and walked me through what they were going to do and took the time to understand my preferences. They had to remove a portion of wall at one point and worked in a pretty confined space to change out the furnace. Most of the mechanical room was finished out and they were able to figure out how to get the exhaust tubing up above the ceiling and allowed me to avoid any drywall repair work. They also ended up needing to bring several items that went to the hot water tank up to code.
We have had a couple of questions after installation and they have been prompt and courteous in their responses.

He cleaned the furnace well, but told me I would probably have to replace the furnace soon. I had another company come to check that out and they told me that the parts were under warranty and really didn't need to be replaced at all.

has a good reputation and lived up to it in this case. They charged me $120 for a boiler inspection that took about 30 minutes. The guy was a couple minutes late but otherwise was professional and explained my options going forward. I would use them again.

Repairman arrived on time and completed the review with his assessment. All worked out fine, no additional parts/service needed.

I saw the product, Aeroseal, demonstrated on the TV show, This Old House. It purportedly improved the temperature differential between upstairs and downstairs rooms and reduced dust by plugging holes in the supply and return air ducts. As soon as I saw the product demonstrated on This Old House, I knew I wanted to try it in my house.
My house was built in 1925 and is a 1-1/2 story residence. I've always had problems cooling the upstairs, even with central air conditioning. In the summer, it is unbearably hot upstairs, even with the a/c cranked up. In the winter, it is coolish upstairs, but certainly livable (heat rises). My house has old style vents on the first floor - large square supply vents (5) and two in-floor rectangular return vents. Upstairs, there are only two supply vents and the return air vent is really the stairway down to the first floor.
The Aeroseal product addresses the excessive duct leakage that exists in any home. Even if you manually seal by tape the ductwork in your house, there is still quite a bit of leakage. I did a lot of research before getting this product installed, and case studies show that this product consistently reduces leakage by more than 90%. Our heating and cooling appliances are now pretty energy efficient, but the duct work in a building is still a source of a lot of heat/cooling loss.
According to the manufacturer, here's some of the technology:
1. Research for Aeroseal was partially funded the US Dept of Energy
2. Aeroseal is the only duct sealant technology that is applied from the inside of the duct system. It is delivered as a non-toxic aerosol mist that seeks out and plugs leaks.
3. Aeroseal has proven to be 95% effective at sealing air duct leaks.
4. The Dept of Energy proclaimed aeroseal technology to be one of the top 23 most important energy conservation technologys for consumer sto come out since the dept was first established.
5. The product was developed at
Saint Paul HVAC Contractors Provider Name Locked
National Laboratory in 1994.
6. Aeroseal has won several prestigious awards, including DOE energy 100 Award, Popular Science -Best of What's New, This Old House - new technologies and 2012 EBie award for use on an existing building retrofit project.
I recommend going to the manufacturer website to get more information and view a video of how the installation works. Also, check out the This Old House segment online when they featured this product.
When I looked for an Aeroseal service provider in the Twin Cities, Northern One Hour Heating & Air Conditioning was the only provider. In fact, I contacted them only about a month after they started providing this product. They had a service technician trained by the manufacturer to install the product, and they had done several new house installations. Mine would be the first "old house" in which they would install the product. (Therefore I did get a very nice price discount.)
The company sent two technicians to install the product. They arrived on time. The set-up definitely takes the most time- it took a couple hours for my house. They have to seal all the vents tightly and tape up larger gaps in the duct work before starting the actual sealing process. They do a computer analysis before and after the sealing process so that actual results can be measured. (One of the technicians still said that my old house duct work was tighter than new house construction to begin with.)
While installing, there was a fine mist that developed in the air. The company has a fan/vacuum that collects a lot of it. Also, they opened a lot of windows to help dissipate the mist. They provided masks for us to wear - I actually didn't wear it though. Breathing the substance created a little stickiness in my nose, but eventually it went away. The mist dissipates quickly. It is supposed to be non-toxic.
The sealing itself took about 15 minutes for the supply side, and 25 minutes for the return side. The supply/return sealing can be performed dually, but this company does each side separately. My results are as follows:
Supply ducts - original leakage was equivalent to a 25 square inch hole. After finishing the Aeroseal, leakage was equivalent to a 1 square inch hole, corresponding to a 95% reduction in duct leakage.
Return ducts - original leakage was equivalent to a 43 square inch hole. After finishing the Aeroseal, leakage was equivalent to a 5 square inch hole, corresponding to a 89% reduction in duct leakage.
Clean-up was quick. They left my house in tip-top shape. I also received a printed Certificate of Completion that outlines the overall sealing results for both the supply and return sides.
I am really pleased with the results, and I can say that the product really works. For the first time, I can cool my upstairs without the use of a window air conditioner upstairs. I can cool it to be about 2 degrees difference from the first floor. I set the thermostat to 74 degrees and close all the supply vents on the first floor except one. Upstairs, the temperature is about 76 degrees. I am anxious to see what happens in the winter, although summer cooling was the more problematic issue for me.
I can also report a HUGE reduction of the dust in my house. Before, I used to see the dust pile up just a few days after dusting. Now, it is over 2 weeks since my last dusting and I still don't see the dust pile up on the furniture or window sills.
I highly recommend this product to any homeowner. It saves energy, is good for the environment, and most importantly - improves indoor comfort and reduces dust in your own home.
I commend Northern One Hour Heating & Air Conditioning for being the first service provider in the Twin Cities for this product. I hope they get a lot of business installing this product. They did a great job and I couldn't be happier.


These guys really know what they are doing. They had appointments available very soon after I called, showed up on time, and worked quickly.

was respectful and polite, and answered all of our questions. He informed me that we would need a new unit soon, but didn't give us a sales pitch.

The tune up went fine. The issues was it was suppose to be on june 2nd and nobody showed up to my house. When I called they were very apologetic because I was in the computer for the 2nd but did not make the schedule board, they then scheduled it for whenever I was available.

First of all, I was so impressed that Friendly was willing to come out on this holiday weekend. I called other places, and either they would only come if there was a baby or elderly person in the house or I would be put on the schedule for about a week out. However, the person who came from Friendly told me that for them most holidays are workdays. I was relieved because it was over 90 degrees inside my house. There was no extra charge for the holiday. I had only been living in my home for about six months at the time, and the repairman told me that it looked as though my air conditioner had never been serviced. There were electrical problems as well as a broken thermostat. My ac is contained in a small wooden structure with a tiny door, and the repairman was well over six feet tall. I have to give him a lot of credit for going in and out of that little box in the heat. He made sure that everything was in working order, and everything's been working great.
- Barbara C.

I wanted to understand why they were declining to do the work. I asked to speak to the owner to get an explanation. They will not respond to my emails (after sending the email that they would not be providing a quote, and then another one saying the owner was out of the office).
I know that fixing another contractor's mistakes is not always attractive, but I think a service-oriented company should be willing to explain the decision. I spent time walking their rep through the house and discussing the problems. When he left there was no hint that they wouldn't do the work.
- Tamar F.

I kept blowing fuses in my furnace and neither a/c or furnace would work. Everyone else would just replace it and not diagnose why it was happening.

spent the time to fix it. Replaced thermostat which was causing the short.
