"NG: After they sell you a unit and when you start having problems, Jonathan Hernandez and his crew will tell you that there's nothing wrong. They will charge for every service call you make and leave you high and dry. I spent $15,000 for their "top of the line, Infinity Carrier" unit with all the energy efficienc BS they advertise. After 2 years of struggles with high humidity problems, high electric bills, VFD faults, and overall frustration with this purchase, this vendor wants to clean their hands and pretend I don't exist. Sadly, google review is my only leverage because they want everyone to get them 5 stars. I would if what they sold me was what they marketed or if they would at least fix what's broken or replace the entire system. My advice to you, find another vendor. Carrier has problems like other manufacturers, but you are at the mercy of who installs your system."

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."

**Please visit our website to see ways in which our services can help with indoor air quality, comfort in your home and energy efficiency. Poor indoor air quality has been linked to respiratory issues such as asthma, sleep apnea and allergies.*** Indoor Air Quality of Texas specializes in sealing Air-conditioning duct work. Aeroseal seals duct work from the inside which is ideal for inaccessible ductwork and we are able to reduce duct leakage to lower levels than traditional hand sealing methods. Sealing duct work improves indoor air quality, comfort and efficiency.

"Sean (the owner) and Jeff were by far the most professional contractors we've ever had in our home. They went above and beyond on design, documentation and cleaning. The work speaks for itself, we had air flow issues in our 1961 ranch home with original metal ducts. Major leak in one area due to a previous contractor (assumption) falling on the duct and the insulation was worn off / torn. Basically, we were cooling attic air... and getting who knows what into our system. Sean went into our attic within a couple of days of our call, took pictures and walked us through exactly what he planned to do. Carefully covering all registers, and the floor pathways with drop cloths, and the beds, then cleaning the ducts, fixing the damage in the attic, replacing all insulation to double thickness of what it was, cleaning out the entire HVAC closet, resealing it, adding sound boards to reduce the noise of our giant 11 year old system... and then the lovely Aeroseal to close up any remaining gaps. Picture perfect. And they cleaned so much with a handheld Dyson! Seriously. Our house looked perfect when they were done. Sean emailed us documentation and pictures with all data points and graphs provided, plus a certificate of completion. So much value. I can't wait to see the reduction in our bills going forward - and avoid replacing our system for a few more years :) My husband asked Sean when we should get the ducts cleaned again; he said we're probably OK not to unless we have major construction. What? Amazing. Such an honest professional. Best decision. Best experience. Call them now before getting yet another so-so HVAC "maintenance" job done..."

Energy Efficiency Auditing questions, answered by experts

There are several strategic ways to lower your home insurance premium. The primary one is to shop around and get quotes every few years to make sure you’re getting the best deal. Also, sometimes bundling your auto and homeowner’s insurance will get you a discount on both. Finally, try to keep your credit score up; many homeowner insurance companies use credit scores to generate quotes.

Hawaii is currently rated as the most expensive state for utilities. How much are utilities for a house in Hawaii? With electricity costs in Hawaii totaling nearly 42 cents per kilowatt-hour, residents are paying more to run their households than any other residents. Electricity costs in Hawaii are so high, mostly due to the fact that most of the electricity available to residents is produced using oil that must be shipped in from other places.

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.

Fans reduce peak cooling loads, lower air conditioning energy expenses by expediting heat exit, and enhance natural airflow throughout the home.

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.
