We exceed our customer’s expectations and standards in a number of ways; such as arriving within the promised time frame or leave our work space cleaner then we found it! 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. Do you have high utility bills when you are running the system, or someone’s allergies are aggravated when running the system? No matter what your need, if it has anything to do with HEATING, COOLING, AIR FLOW, or AIR QUALITY; TRINITY HEATING AND AC is ready to help!

"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

Smart glass doesn’t use a lot of electricity, and you can expect a standard window to add between $1 and $2 per year to your electric bills. Smart glass is proof that energy-efficient windows work. Although your smart windows may consume a little energy to operate, they can save enough energy to offset the costs. If you’re concerned about the minimal bump to your electricity consumption, you can opt for smart tint, which doesn’t require electricity to work.

String lights require electricity, but not an excessive amount, especially when compared to other lighting fixtures. LED rope lights, for instance, consume around one watt per foot. Running six or seven light strings simultaneously should only cost you around $10 to $15 each month. You can save even more money by remembering to turn off your lights during daylight hours. 

Gas fireplaces use either natural gas or propane—both of which will increase your energy expenses. On average, running a gas fireplace costs $400 to $640 per year; however, these costs can vary significantly depending on the fuel price in your area and the frequency of fireplace use. If you’re looking for a more energy-efficient option, consider switching to an electric fireplace.

Yes, energy-efficient options such as LEDs and solar-powered lights are available. These alternatives consume less electricity, resulting in lower utility costs. They are also more environmentally friendly due to their reduced carbon footprint and longer lifespan.

Insulation is measured by R-value, which is the measure of a material's ability to resist heat transfer. The higher the number, the better the insulation. When installing insulation yourself, you need to determine the optimal R-value you need to keep your home warm in the wintertime, cool in the heat of summer, and energy-efficient all year long. Each inch of insulation provides between a 3 and an 8 R-value. The climate where you live plays a major role in what R-value you need and the price tag you might see in your insulation installation.
