Service Champions is the leading heating and air conditioning contractor in Northern California servicing homeowners in East Bay, South Bay and Sacramento areas. We can make your home more comfortable and improve the quality of air you and your family breathe. We specialize in maintenance, repair and sales of all brands of air conditioners and heaters, and are experts in indoor air quality improvement through filtration, duct replacement, insulation and hospital grade UV lights. All the air conditioners we install have the new environmentally friendly refrigerant that does not damage the ozone. We also are huge proponents of super high efficient equipment, such as 95% efficient furnaces. This equipment saves homeowners a tremendous amount of money on their utility bills.

"Just had the initial diagnostic visit. I was given terrible news (I'll probably end up getting a new furnace $$$), but the technician Ricky was wonderful. He was extremely polite, professional, and friendly. He did a very thorough inspection and then gave me a very thorough explanation of the problems. This included photos he took on the spot of some internal parts (oil leakage, heavy dust & dirt, stress markings).... at no point did I feel like I couldn't trust what he was telling or showing me. He answered every question I had. He went into the "attic" of my Eichler to check the ductwork (via a 14" hole in the closet ceiling, into space so shallow and tight I have no idea how the ductwork was ever even installed), and came out with photos to show me. The company was easy to work with when I had to change appointments, sent me email and text confirmations of everything, and gave me a day-before reminder of the appointment. I had an 8a- 11a window and received a text at 7:50a letting me know the technician was on his way, with a photo of him included. Perfect, perfect, perfect. The visit was $89 but reduced to $39 because I signed up for the MVP membership: $107 for a year which gets me all kinds of free services plus discounts on everything else. It even includes services on my water heater which they did not install! Additionally, they have some really good guarantees, MVP or not. Before leaving he called the office, explained all he'd found, and handed me the phone to set up an appointment with a "comfort specialist". Ariel (on the phone) was also extremely polite, professional, and friendly. These people are trained right! Or they're hiring very well. So, I will be meeting with someone to discuss repairs vs. replacement options. No repair work has been done yet (although Ricky did do a temporary fix that is allowing me to get some heat), so I can't fully review the company. But thus far I'm 100% pleased. This is probably the best experience I've ever had with any kind of repair technician. I've never used them before and have also never written a review before. The experience was just that good. I'll write another when I've finished with them just to give a full review, but so far perfect!"

We can take on a wide range of residential projects to include computer network or wiring, telephone, security system installs and a variety of other projects. We take pride in the quality of our work and our commitment to outstanding results. We look forward to building strong, long-term relationships with our clients and guarantee your satisfaction.

"Joe is hard working, diligent, and honest. I hired him 1) to put up an antenna for local tv service and 2) to fix poor wifi signals. TV was converted from cable rapidly using leftover wires. Saving $ not paying for cable and streaming off wifi. Great signal strength! WiFi was harder. He worked with ATT to determine my new iMac was sucking signals. He installed a more powerful router that solved wifi issues when iMac is off. Now I have to work with Apple to figure out how to manage the computer searching. I would not hesitate to call Joe back again. He is an excellent technician and a fine person. He is pretty busy, so sometimes it takes a few days before he can come out, but he is worth the wait."

Generator installations FAQs

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
