"Maps autocorrects to wrong street. Went to wrong location even after informed them. An hour late. Seemed to be done in average time. Powdery residue covering entire basement floor. I had to sweep and vacuum up. When they say you will be out of your home for 24 hours they are not kidding. Fumes pretty noticeable. Able to return after 36 hours."

Hi, I’m Mrs. Michael, and when you need something repaired, We wanna be your guy. Back when I was raising two babies, my husband and I started a plumbing company, an electrical company, AND a heating and air company. Mr. Michael is a genius with tools, but he did NOT enjoy running 3 big companies, so he asked me to do it. Turns out, I LOVE it!! I believe that if we make your problems disappear quick and easy, then when someone you know needs something repaired you’ll say: “I’ve got a guy! . . . Her name is Mrs. Michael.”

"I called Mrs.Michael plumbing and electrician on a Sunday and was told the service call would cost $129. However, I wasn?t informed that the $129 only covered the technician?s arrival. Once on-site, I was told diagnosing the issue would be an additional $450 ? and that price only covered two outlets, with anything else costing extra. I?ve rented homes for over 30 years, and I?ve never encountered such misleading pricing practices."

Energy Efficiency Auditing questions, answered by experts

You can determine what size generator you need by listing the various appliances it will power during an outage. Write down the start-up watt usage, and then add them all together. 

A 7,500-watt generator will run your refrigerator, freezer, well pump, and lighting circuits without a problem. However, you’ll need an extra 3,000 to 4,500 watts to run your water heater and another 5,000 to 25,000 watts to run your electric furnace. In these instances, a whole-home generator is your best bet for running your critical equipment.

Generator size requirements vary wildly among properties, but typical generator sizes are listed below based on home square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14kW

  • 2,500 sq ft: 12–16kW

  • 3,000 sq ft: 16–20kW+

Unfortunately, home square footage isn’t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you’d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.

There are several indications of an overloaded electrical panel, such as frequent circuit breaker tripping, burn marks, or flickering or dimming lights.

If you’re observing any warning signs, turn the circuit breaker off, then shift some devices from the overloaded circuit to a different one. If there are still signs of overload after turning the circuit break back on, contact a professional electrician to help you fix the issue.

Yes, a dirty air filter can cause a higher electric bill. That’s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the U.S. Department of Energy, replacing dirty filters can save you between 5% and 15% in utility costs.

The three levels of home energy audits include:

  • Level 1: Review of your energy bills and home for signs of energy inefficiency and areas for improvement. The average cost range is $0.08 to $0.12 per square foot.

  • Level 2: A level 2 ASHRAE energy audit costs $0.12 and $0.35 per square foot. In-depth analysis of your energy usage and provides a report of cost-saving changes.

  • Level 3: Comprehensive analysis and detailed recommendations for ways to improve your home’s energy efficiency. A level 3 audit costs about $0.36 to $0.50 per square foot.
