1.9k+ For the bare minimum of getting paint on walls, great. Even coverage, smooth application. Finishing touches? Terrible. The logic behind which out covers they actually took off vs just painted into the wall makes my head hurt. They covered the wood floors, but put nothing down over the carpet....
JMJ PaintersWe hired Erickson to replace the water heater in our St. Paul home. Overall it went well, the only snafu was a one-day delay from when they initially said they could be out. Price was in-line with other bids we received, although Erickson did not charge us extra for a code update another...
ERICKSON PLUMBING HEATING COOLING INC/ERICKSON PLUNothing as complicated or time consuming as I feared. Did the repairs as needed without trying to sell me any replacement equipment, which I sometimes find other companies are eager to do.
Norblom PlumbingIt was repaired in the time frame they gave me. The cost was what I was expecting. I had the option to refuse to have it repaired if it was more than what I was willing to spend on an old machine. It was a good experience.
Overall my experience with this company was very positive from start to finish. They were able to provide a very quick appointment. Matt was very thorough and gave me direction on resetting my boiler. I would definitely recommend this company.
Hero Plumbing, Heating & CoolingAbsolutely wonderful service. Professional, dependable, honest (sometimes I just leave the back door open so he can come in and get the work done!), and knowledgeable. I know from his excellent work with another customer that he knows his boilers, too! No need to call anyone else but Thoennes!
We have a yearly service agreement with Scott. On this visit, he serviced the furnace and air exchanger. He will come back in the spring to service the central a/c - the $300 includes that future visit. Scott explained that our furnace will need replacement in the next few years. This will be...
S & R Heating, Cooling & Appliance RepairOur furnace/boiler was not working since last spring. Snelling came and checked it out, did maintenance and explained to me how we can maintain the system better in the future. He fixed the problem, and explained everything he did. He was very professional and helpful.
Snelling Heating Cooling ElectricalJob 1: Gas company had shut down boiler due to gas leak.

We are committed to providing friendly, hassle-free service and employing only the best technicians. Pronto is proud to have won the Bryant 2009 Dealer of the Year award.

"I have called and sent many emails/reviews. I have a disability and use metro mobility pronto keeps allowing their driver that lives in Friday to park their company vehicle in the street it prevents 2 way traffic metro mobility had to wait for the vehicle to clear before I could get picked up I was even late for my appointment. What a terrible way for a company to treat a person with a disability"

You deserve a safe and reliable home. Get the job done right the first time with outstanding customer service from the Twin Cities top rated electrician. Outlets, fans, lighting, smoke detectors, switches, and service panels. Your full service electrician.
"I hired Randy’s to fix a recurring electrical issue that was cutting power to the upper floor of my home, and to install two new circuits, work completed over two visits about a week apart. The new circuits seem to work fine, but the original issue persists—despite spending over $5,000, including $1,000+ on diagnostics. The electrician spent about 45 minutes on the initial assessment, then replaced some wiring and breakers. The problem reoccurred before the second visit, which I reported by phone, but he was unaware of it when he arrived. He did minimal follow-up, blamed CFL bulbs, and later suggested the issue might be with outlet or switch connections—something I believe should have been checked from the start. The issue has since returned again, and after three follow-up calls in three days, I’ve received no response. On the positive side, the crew was professional, worked in a difficult attic space, and cleaned up well. Still, I expected better troubleshooting, communication, and post-service support for what I paid."

"WARNING - make sure you get a fully price estimate up front before they begin to do work. I brought them in to work on furnace/AC unit/split AC unit servicing garage (based on a promotional price for the first two). It was found my split unit needed a recharge for coolant and I was told that it'd only be 5 lbs of coolant and that this would be priced by the pound (which was reasonable). The bill came and they tacked on a flat charge of $219 for the coolant (this is in addition to the $129 charge to look over the split unit). I felt baited-and-switched. I also contacted them about this, and the answer came down to "This is additional profit for us added onto your bill." Not pleased. At all. Particularly since the coolant in question costs approximately $6 per pound and they only used 5 lbs (one would assume that the $129 charge built in enough profit for labor/licenses/equipment due to the limited time spent working on the split unit. Apparently not). Comfort By Design does excellent work, and they do stand by their work, but just be VERY CAREFUL in finding out what they're going to charge you, particularly if something extra comes up when they're doing a job."

The average cost to install a new water heater is around $1,300, but you can expect to pay between $875 and $1,750, depending on the kind of water heater, the size of the unit, and the professional chosen to complete the work. Tankless water heaters can push your price higher, as installation is more complicated, with prices as high as $3,500. The location and accessibility of your water heater will play a role in the project cost, as those sitting in tight spaces like a crawl space will drive up your labor costs.

It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.
The average cost to hire a plumber is around $100 an hour but can vary between $45 and $200 an hour depending on the plumber’s experience and the repair that you need. It’s also important to note that these prices can go up on holidays, and emergency plumber rates average $150 per hour, in addition to a flat-rate trip fee of $100 to $350.
