"Tony and his team from Duran HVAC are the A team!! I give them an A++ on their work for us. Tony came out and has very helpful in thinking about the overall job, and we discussed options. His team led by Paul then came out and completed all the work described above in 4 days. Tony came by and checked on the work progress as well. This team is so skilled at what they do, they are a pleasure to work with, very careful with tarps and cleaning up each day, and the work has been completely superbly! They tested the system at the end of the last day and showed me how to program the two thermostats. They are the best! This is the beginning of an excellent long-term customer-service relationship. I will definitely be asking them to come back and handle the yearly maintenance checks of the systems. It is wonderful to find a team you know are highly competent, reliable, and great to work with! I highly recommend them to others! Do yourself a favor and call Tony at Duran HVAC now! You'll be very happy you did!"

We are a family-owned company that has been in the spray foam business for over 20 years serving Fresno, Clovis, Bakersfield, Oildale and surrounding areas of Visalia California for many years. Spray polyurethane foam (SPF) is a spray-applied plastic that is widely used to insulate buildings and seal cracks and gaps, making a building or home more energy-efficient and comfortable. SPF insulation is known to resist heat transfer extremely well, and it offers a highly effective solution in reducing unwanted air infiltration through cracks, seams, and joints.Attic Spray Foam Insulation Did you know you could be losing up to 40% of your homes energy through the attic alone?! Using Spray Foam Insulation in your Attic is the only solution you should be considering to remedy your attic’s insulation needs. The attic is the part of the house which is easily over looked, but it is also the part of the home that is most susceptible to the external temperature changes. If you attic is not properly insulated it can lead to huge amounts of energy loss and the fluctuation of the temperature within your home. Proper attic spray foam insulation serves as the key to limit and control the effect of the external temperatures on your homes interior environment, monthly energy bills and energy loss.

"Rusty Schrader the owner/operator is a life saver and went out of his way to help me. He is very knowledgeable in the business and I highly recommend this company. You won’t find anyone more honest, helpful, and responsive so don’t even bother looking"

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.

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

Yes, skylights can affect a home’s energy efficiency, either positively or negatively. Properly installed, energy-efficient skylights with Low-E coatings, double glazing, and UV-blocking glass can help regulate indoor temperatures and reduce heating and cooling costs. However, poorly insulated or older skylights can contribute to heat loss in winter and excess heat gain in summer, lowering overall energy efficiency.

As you look for the right soundproofing drywall for you, you’ll likely come across the Sound Transmission Class (STC) rating. This rating measures a building material’s ability to absorb sound. The higher the number, the better the material absorbs rather than reflects sound, reducing noise transmission. The STC rating for drywall doesn’t mean it’s for the panel itself—it refers to the STC rating for the entire wall system, including the soundproofing drywall.

STC (Sound Transmission Class) ratings tell you how well something blocks airborne noise. It’s a single number that sums up how much sound a material, like a window, can stop across regular speech frequencies. The higher the number, the better the sound reduction. A typical single-pane window hovers around STC 25 (where you can hear normal conversations), while well-sealed, double-pane options can push past STC 45 (which blocks out loud speech and most music). Just keep in mind that STC doesn’t cover everything—low rumbles like bass or thunder can sneak through—so pairing methods are always ideal for the most peace and quiet.

A home energy audit costs about $420 on average, ranging from about $100 to $2,250 or more. Cost factors include the size of your home, the type of testing, and the thoroughness of the audit. A Level 1 walk-through inspection will cost between $150 and $200 for the auditor to point out inefficiencies in your home. On the other hand, a more thorough Level 3 audit with testing and a detailed report will cost about $900.

An average, 400-square-foot electric heated driveways consume approximately $3 per hour in terms of electricity. The price may slightly fluctuate depending on your local energy cost. A simple formula to calculate your heated driveway’s total wattage consumption is by multiplying the square footage by 50 watts and then dividing it by 1,000 to get the kilowatt number. Multiply that with your local energy cost per hour and there you have the hourly operating cost.
