True or false?

Your thermostat shouldn’t be able to get below 80 degrees?

FALSE!

If your air conditioner is running but your house still won’t cool down, replacing the A/C unit may not solve the real problem.

Your home could be gaining heat faster than your system can remove it.

Poor insulation, attic heat, air leakage, inefficient ductwork, and other problems throughout the home can force your A/C to fight a losing battle.

 Trustindex verifies that the original source of the review is Google. They showed up to install insulation, but warned us about some knob and tube in our attic and how it could affect the insulation installation. They recommended getting it checked out by an electrician before they started blowing in insulation. They then packed up all of their stuff and came back after we got it checked out by an electrician. I’m not sure any other company would have my interests in mind and pause before they get paid. Great guys to work with!

 Trustindex verifies that the original source of the review is Google. Dakota and his friend did an excellent job insulating both of my homes. They were professional, hardworking, and paid great attention to detail from start to finish. They kept me updated throughout the project and even sent before-and-after photos, which showed the quality of their work. They added the full 10 inches of fiberglass insulation as promised, cleaned up after themselves, and made the entire process easy and stress-free. I truly appreciate their honesty, communication, and dedication to doing the job right. I highly recommend Dakota and his team to anyone looking for high-quality insulation work. Thank you both for an outstanding job!

 Trustindex verifies that the original source of the review is Google. Just had our attic insulation replaced today.  The GHE techs were professional and punctual.  They explained everything they were going to do and cleaned up the area when they were finished.  They are very affordable as well.  I highly recommend giving them a call!
