"During a service in May 2025, a technician suggested potential mold issues but failed to document these concerns in the subsequent paperwork. Additionally, during a winter check in November 2025, a different technician warned me of necessary repairs and implied a potential fire hazard related to my heater; however, this information was also absent from the official records in both situations. After seeking a second opinion from another company that deemed my system safe, I expressed my dissatisfaction to owner Andrew Dobbins. I requested a prorated refund for the three years left of my membership. A follow-up from Service Manager, Paul Matthews, indicated that my system was not as dirty as originally claimed, prompting me to question the integrity of the services provided. My request for a refund was declined, and a subsequent call with Mr. Dobbins escalated, as he accused me of attempting to extort money, rather than addressing my legitimate concerns about his technicians' practices"

Day Star Electric is an award-winning provider of residential electrical services. Our family owned and operated business has been providing exceptional electrical assistance to the Tucson area for the past 20 years. We take pride in offering a wide range of options to our customers.

"terrific! It took Day Star about an hour to locate where the break in the circuit was (in the wiring behind an old smoke detector). Two other Angi-highly-rated companies had failed to diagnose the problem. Day Star squeezed us in early on their schedule. The two person team was friendly, professional, and super skilled. I'm hoping to keep using Day Star for all future electrical issues that may come up. From our experience they are absolutely the very best."

Generator Install questions, answered by experts

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

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.

Yes, whole-house generators run constantly for extended periods. Whole-house generators can run for longer periods of time than portable generators, but be careful. First, they may need regular applications of engine oil (as frequently as daily), depending on the engine design. Second, running constantly for several days will increase the wear and tear on the generator and shorten its lifespan.

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.
