Hello. We want you to know we are taking extreme precautions with the current situation, so neither, you, your household/business or our techs are affected. We pre-screen all technicians every morning, checking for any signs or symptoms of the virus. All of our technicians wear protective gear, such as gloves and mask. They wash their hands prior to entry into your home and will practice social distancing while with you. It’s all part of an 8 step process we now go through to protect you and our technicians. As the weather is uncertain in the weeks to come, you and your family will be spending more time at home. You will definitely want to get your system ready, so no issues arise. Most of our work will be done in your attic, on your roof or outside. We will spend very little time in your home. Here at Coolmark Heating & Air, we are a locally owned and operated company that values honesty, integrity and treats your home as if it were our own. We offer a variety of quality home improvement services. You will find us to be competitively priced with close attention to the details of each and every project that we are involved with. We look forward to building lasting relationships and guarantee your satisfaction. We are on call 24/7 so please don't hesitate to reach out to us. Lastly, stay healthy and safe, we will overcome these trying times.

"We have had the best experience with the team at CoolMark and the owner himself, Mark Garza. They have gone over and above to help us out when our AC unit died, and even after the installation to ensure everything is working correctly. I felt bad bugging them when our new unit wasn't working right but they kept coming out until they discovered the problem, even coming out twice in the same day! Their services and the product they install were very competitive price wise and they worked with us to get the best financing options. I would highly recommend Coolmark Heating and Air to anyone needing service on their current unit or installing a new unit all together. You won't be disappointed!"

In other words, regardless of where you are in California, we can help you make the switch to solar! Not only do we offer top-tier solar services, we are also a total home performance company, devoted to sustainability and energy efficiency. We offer fully customized home and business solar installations with battery backup capabilities. We do not service solar systems that we did not install. We believe the future is clean, renewable energy and with your help we are committed to creating it together. Customer satisfaction is a crucial aspect and the cornerstone of our business. As a result, we have earned the prestigious Diamond Certification 4 years in a row, along with the 2019 Angie’s List Super Service Award. NRG Clean Power offers the finest solar products at the best rates with finance options for everyone. We will be with you every step of the way and for years to come. Check out our promos to take advantage of our best deals. And ask about our Referral Program that allows customers like you to earn cash bonuses for referring friends and family!

"No doubt they hire great installation people, but their communication and honoring their quotes has little to be desired. I will elaborate. I was given a quote, left on my voicemail. I responded the next day letting NRG know I accepted their quote. 1 week later I received a phone call telling me they wouldn't honor the quote give, and they cited the reasons as Tarif's. This was back in April 2025. I still went with NRG, albeit at a$1000.00 increase. The second reason I wouldn't recommend this company, and this for me is the final straw, after installing my solar NRG didn't let me know I needed to have an ESR release, in layman's terms this is necessary for your power company to accept your new solar system. I found out this information when they contacted me in August 2025. NEG blamed the company who upgraded my Electrical Panel. NRG INSTALLED MY SOLAR AFTER THE PANEL WAS UPGRADED. Since this company doesn't communicate with its clients I would say go with another company."

Energy Efficiency Auditing questions, answered by experts

Smart home upgrades can be worth the money. Several upgrades, including smart thermostats and ceiling fans, can help reduce your energy bills. Others make life more convenient, freeing up your time to do what you love (or get more work done). And some smart home upgrades, such as entertainment systems, simply make life more enjoyable. All are worthy causes.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.

Window AC units use a fair amount of electricity during use, but the usage pales in comparison to central units. As a matter of fact, window units use around a third of the amount of energy as a central AC. On average, a window air conditioner costs between $15 and $40 per month to run, though this depends on a number of external factors.

Home power is measured in kilowatt-hours, commonly expressed as kWh. The average home uses between 800 and 1,000 kWh per month. Peak usage (and highest bills) occurs in the middle of summer and the depths of winter. Keeping on top of your usage during these crucial months will lower your annual average usage considerably. 

The three levels of home energy audits include:

  • Level 1: Review of your energy bills and home for signs of energy inefficiency and areas for improvement. The average cost range is $0.08 to $0.12 per square foot.

  • Level 2: A level 2 ASHRAE energy audit costs $0.12 and $0.35 per square foot. In-depth analysis of your energy usage and provides a report of cost-saving changes.

  • Level 3: Comprehensive analysis and detailed recommendations for ways to improve your home’s energy efficiency. A level 3 audit costs about $0.36 to $0.50 per square foot.
