We offer professional technicians, same-day installations and 24-hour emergency service. We believe we are the right choice for any of your HVAC, Plumbing, or Electrical needs. Call today to schedule your next appointment!

"Had an old fixture above kitchen sink go kaput (fluorescent starter disintegrated), so Cardinal came out and offered LED alternatives (two provided, brought on-hand from supply warehouse). Also fixed a switched outlet that had shorted out. Great work done, nice alternatives for the LED light, and switched outlet was wired to be always-on for one socket and switched for the other -- better than it was before at no additional cost. Later I called to ask the exact serial and model number of the LED light because the papers left did not state it. Not only did I get an email a couple hours later with the model/serial, the tech included the detailed documentation for the fixture so if anything goes wrong I can likely fix it myself next time. The tech who did the work also applied a 10% off discount card for me with no extra hassle, saving me close to $100 on the work."

Generator Install questions, answered by experts

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.

No, you shouldn’t use an extension cord to plug a generator directly into your home without using a transfer switch. That’s because systems like pumps and HVAC fans need a steady power source that might not be available directly from your generator alone. If you bypass the circuit breaker box, you risk damaging your electrical system, creating a risk of electrical fire or electrical shock to you or any workers repairing lines on your local electrical grid.

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.

If you’re wondering if you can use your electric vehicle as a backup battery, it depends on whether your EV is compatible with bidirectional charging. This technology allows energy to flow both ways, enabling vehicle-to-home (V2H) backup power, vehicle-to-load (V2L) for appliances and camping, and vehicle-to-grid (V2G) to support the power grid. Compatible EVs convert stored DC energy into usable AC power, helping reduce energy costs and enhance grid stability while providing emergency backup power.

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit
