"From beginning to end, The Right Choice Heating and Air Conditioning Co. provided superior quality customer service and onsite work. From scheduling, to multiple follow-ups and reminders, re-confirming exact appointment time, and the post-inspection follow-up, they have truly impressed us. More importantly, Michael Taib, the technician who performed the work at our home, was indeed a true gentleman and professional. He was extremely knowledgeable and patient. I am familiar with the type of HVAC related work requirements, the lingo, and technician data. I quizzed him several times and he constantly responded with 100% honest and factual answers. He tirelessly worked on both of our HVAC units and performed the necessary services and repair. He was polite, courteous and clean. His most impressive talent was ensuring my wife's absolute confidence in his work after she grilled him with so many questions! We will continue to refer True Choice to all our friend and family! Call them; you will not be disappointed."

We provide custom solutions that take all factors into consideration so we can design a system that will meet the needs of your home and everyone in it! We offer so much more then just replacement of your existing system or installation of a new one.

"Chris was able to fix our ac unit, where my old account guy said we NEEDED to replace it!!! Plus Chris is very personable and I believe he is very honest and forthcoming as he could have sold us a new system, but found us a much cheaper option!!"

https://personalpowerproject.com/ Personal Power Project - Solar Panel Installation Business. We install solar panels, and our specialty is helping people to reduce all of their energy bills to ZERO per year, when the average in CA is approaching $10,000 per year. For most people their electric bill is only one third of their total energy expense. Natural gas or propane gas for your home and gas for your cars amount to the other two thirds. This takes long range planning and that is what we do. If you need an emergency repair or service ASAP, we do that too although it's not our main focus so probably faster to get another company for emergency jobs. Our business model is to help you go 100% off grid while still being connected, if and when you need it. It's easy to be 100% off grid if you are not 100% electric. Being 100% off grid and 100% electric, on everything else is difficult and takes a lot of research, resources, planning, and some good advice and direction. Governments worldwide are mandating the all-electric movement so there is no avoiding it. It might take years for you to get there, which is not unusual and it's worth it, to eliminate $10,000 worth of energy bills per year which continue to climb higher each year. We dispatch our local solar contractors from our nationwide solar companies, of your choice, for all the help you need.

Energy Efficiency Auditing questions, answered by experts

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

There are a couple of ways you can save on the cost of your home energy audit. First, find out if you qualify for programs like the Department of Energy’s Weatherization Assistance Program for low-income households. Next, check with your local utility company to find out if you qualify for any local rebate programs to offset the cost of this helpful service.

The effect a gas fireplace has on your gas bill will depend on how often you use it, the size of the rooms you’re heating with it, and the BTUs of the fireplace itself, but generally speaking, it should only cost a few cents an hour to run it when it’s on. It will consume minimal energy when it’s “off” if you have a pilot light running constantly, but some modern gas fireplaces don’t require a constant pilot light.

The difference between an energy auditor and a home inspector is primarily in the purpose of the inspection. The energy auditor conducts tests in your home to determine the energy efficiency levels in areas like windows, insulation, and doorways. The auditor then makes recommendations for ways to improve a home’s energy efficiency

A home inspector examines various structures of your home to determine that everything is up to code and gauge the condition of features like the roof, foundation, HVAC, and electrical. The home inspector reports on the overall home and makes repair recommendations.

Solar water heating systems are not one-size-fits-all. You'll likely work with a team of experts to get the job done—including solar panel installers, plumbers, and water heater installers. A specialist will help you decide if a passive or active system is best for your local weather, home layout, roof stability, and your budget.
