As the trusted neighborhood HVAC service team in Milwaukee, Mr. Holland’s Home Services is committed to running their business based on five important principles: care, empathy, and trust, being always available, outworking the competition, quality workmanship, and using their “find a way” method. By keeping these five principles in mind, the business is able to deliver nothing less than excellent work when it comes to heating, air conditioning, and indoor air quality services. The professional team at Mr. Holland’s Home Services always gets the job done right. They never cut corners and are respectful of a customer’s property. Additionally, Mr. Holland’s takes their community involvement seriously; that they have a personal responsibility to help the people in their community, not just through quality services but also through the endless support they give to organizations and charities throughout Milwaukee and even outside the country. To learn more about Mr. Holland’s Home Services, please visit the company website or call the office today.

"On September 11, 2025, I hired Mr. Holland’s to clear and diagnose a main line clog. I was charged $738.04 for drain cleaning with a snake. The invoice states the technician attempted to snake the line multiple times but could not get it open, and because the drain was still impacted they were unable to camera the line. I was told the blockage was around 90 feet from the access point, but my own measurements showed that distance would place the problem across the street, which did not make sense. In reality, the blockage was never cleared and the scope I paid for was never attempted. Even though the line was still blocked and never scoped, I was given a written estimate for $39,900.34 to excavate and replace about 7 feet of my sewer lateral. That estimate included removing two sections of sidewalk, excavating down 9 feet, cutting out and replacing pipe with PVC and a cleanout, slurry backfill, and sidewalk replacement — but no landscaping restoration. No spot-repair options were offered. I later hired Subterranean Sewer Experts, who scoped the line and found the actual blockage about 30 feet inside the basement, not 90 feet away. They also scoped another access point closer to the street, which confirmed the sewer lateral was clear and did not need replacement. I had paid Mr. Holland for clearing a clog and performing a scope, neither of which were done. I was told by both phone and text that my payment would be refunded; I even saw the refund pending, but it was later reversed without notice. Because the blockage was left in place and the scope was never done, I was forced to hire another company and pay an additional $747.40 to complete the work Mr. Holland’s failed to perform. Based on my experience, I was charged for a service that was not performed, left with a blockage still in place, given a nearly $40,000 estimate for unnecessary sewer work, and denied a refund that was promised."

Generator Install questions, answered by experts

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

The typical cost of a home generator is around $5,000, but prices range from $400 up to $13,000, depending on a few factors. The most significant cost factor is the generator size, as larger generators that can support more square footage usually cost more. You can install an emergency backup generator for between $500 and $2,000 or a partial-home generator for between $2,000 and $6,500. Whole-home generators usually total between $5,000 and $13,000, with some models climbing as high as $18,000.

A whole house generator can be worth the extra money for peace of mind if your home is prone to power outages for extended periods of time or if you have life-saving medical equipment that needs to maintain power at all times. These devices can also increase your home’s value, especially in areas prone to extreme weather and power outages.

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.

By submitting this question, I acknowledge and agree that Angi may publicly display my name, city, state, and question on the website for professionals and others to see.
