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."

"I am a 76 year old woman who lives alone. I have three bathrooms in my home and called Boevaag Plumbing to repair one of the toilets. The service on August 22, 2024, was a replaced fill valve and flapper and the cost was $195.00. As long as the plumber was already onsite, I asked him to look at a second toilet that I thought might also needed a new fill valve and flapper. The plumber confirmed that was needed and asked if I wanted him to go ahead and do the repair. I asked him to do so. I naively did not ask what that additional repair would cost and assumed it wouldn't be another $195 as he was already on site. The plumber was very nice and left my home in clean condition. On completion of the second repair, I received a bill of $390! I was speechless and just wrote out a check. I wrestled for a couple of weeks with whether or not to call just to communicate my thoughts. I decided to write it off and never make the same mistake again. Shortly after the repair, the second toilet was giving me some problem. I called Boevaag and Jeff came out, at no charge. He found a piece of plastic in the new part that he thought was the culprit. A few weeks later the same issue presented. On December 5, 2024, I called Boevaag and told them the issue had not been resolved. Joe said he would get back to me. I called again on December 13, 2024 because I had not heard from Joe, left a message and Joe texted back, "Yes, you are on our list. With this cold weather we have been backed way up." With Christmas and the new year coming up, I chose to wait to hear back. Today is January 6, 2025. As I have not heard back, I called and talked to Joe. Joe assumed Jeff had followed up and resolved the issue. As that is not the case, I offered to accept a $150 refund and I would hire someone else to fix the problem. Joe said he would talk with Jeff to get the problem fixed and he hung up. I know plumbing repair is expensive and I may be wrong, but I feel, as an older single woman, I was taken advantage of. Joe has no customer service etiquette. He is rude and condescending. NO....I would definitely not recommend Boevaag Plumbing."

Water Heaters questions, answered by experts

Tank-style hot water heaters need replacing about every six to 15 years, while a tankless model can last 20 years or more. Over time, water heaters fill up with sediment that can start causing issues. If your unit is ten years old, start thinking about a possible replacement. Flushing your tank-style water heater annually and having routine maintenance done can increase the life span of the unit.

Every type of water heater has its advantages and disadvantages. Understanding those can help you decide the best type for your situation and budget. 

Pros

  • Safer than gas or propane

  • Doesn’t require extensive venting systems

  • Lower upfront costs

  • Simpler to operate

  • No pilot light

  • Easier installation

  • More efficient heating than gas models

  • Available as point-of-use (POU) and whole-house units

Cons

  • Slower to heat water

  • Longer recovery time

  • Possibly higher operating costs

  • Doesn’t work during a power outage

  • Costs can increase without a 240-volt connection

A tankless water heater with a flow rate of 10 GPM should replace a conventional 50-gallon water heater. To avoid a surprise cold shower or two and to keep your energy costs in check, it's important to replace a conventional tanked water heater with the equivalent tankless water heater. Your household size and the number of hot-water-using devices you use at once can help you determine the best-size tankless water heater.

There are pros and cons to tankless water heaters. They are more efficient than traditional tank water heaters, and maintenance costs are lower. These units are also much more compact. On the other hand, they cost about twice as much to install as traditional tank water heaters and are more limited in terms of flow rate.

Installing a water heater without a permit can result in high fines—as much as hundreds of dollars per day, in some areas. It can also void your homeowners' insurance and cause problems when selling your home because it violates local building codes and safety regulations.
