Any residential, commercial, repairs or add-ons, Fair prices, dead-line always a must, owner-operated 20 years experience
"Had a great experience with the technician who came to install my EV charger. During the installation, a small part was missing, and he went out of his way to drive to Home Depot to get it—really appreciated that! I also happened to have a security camera I wanted to install in the garage and asked if I could borrow his ladder. Not only did he lend it to me, but he also helped me install the camera, all without charging any extra fees. Excellent service overall—very professional, friendly, and helpful. I’ll definitely reach out again in the future. Highly recommended!"

"I would say this is the BEST SERVICE YOU CAN FIND for HVAC. I had an intermittently functioning heat system where we almost replaced the $300 Next thermostat and ran a 40 foot power wire through the walls, which would have cost quite a bit. Instead, a very capable man did the right testing and found we only needed a capacitor and he had one on his truck. He then spent another hour removing the dirty fan and cleaning the whole system with Shopvac and garden hose. We'd been breathing all this dusty air and did not know it. They came the day we called and everything was handled expertly after two weeks of problems with heat and incorrect solutions suggested. Highly recommended and I will save their number!"

FAQs for generator installation projects in Calimesa, CA
Installing a whole-house generator costs about $5,000 on average. Prices range from $1,550 to $8,500, depending on size, brand, fuel type, and assembly. The size of your whole-house generator is the most significant cost factor, with large homes with high energy demands costing the most to power. Types of whole-home generators include:
Portable generators with 1kW–7.5kW capacity: $500–$2,000
Partial generators with 9kW–20kW capacity: $2,000–$6,300
Whole-house generators with 22kW–48kW: $5,000–$18,000
When maintained properly, a whole-house generator can last up to 20 years. Costs to maintain and repair generators vary by location and type of generator, but you can expect to pay about $150 to $300 per year for annual generator maintenance checks. An experienced generator service technician will inspect your generator’s engine filter, starting mechanism, fuel, lubrication, and coolant levels to keep your generator in good working condition for as long as possible.
When choosing the right size generator for your needs, consider a few items to help calculate the wattage you’ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:
Refrigerator: 600 watts
Large dehumidifier: 700 watts
Large window air conditioner: 1,400 watts
Water heater: 3,000 watts
Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running.
Here’s what you can run with different wattages and types of generators:
Portable generator:
2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers.
4,000 watts will keep two large appliances operating and a few smaller devices.
8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.
Partial to whole-house generator:
20,000 watts and above will make it seem like your home’s power is still on.
The value of installing a whole-house generator is that your home has guaranteed power, even if the power grid in your area is down. Whether a whole-house generator is worth installing in your home depends on how often you use it, your home’s location, and your lifestyle. For example, installing a whole-house generator is likely worth it if you:
Experience frequent or prolonged power outages
Work from home
Store a lot of cold food
Have a sump pump
Have a pump for well water
Use electronic medical devices
Live in a climate requiring heating or cooling
