"Everything went pretty well. We were especially pleased with the insulation installer. The assessment seemed a little cookie cutter. The assessor setup the blower device and wanted to be on his way ASAP after it was completed. They generated a huge report with recommendations and explanations of energy audits, energy use, potential savings, etc. I had some followup questions, the home energy auditor was not always responsive to email questions. I have more questions than most people. Generally speaking the job was done relatively well and I'm confident our home is less drafty than before."

"My objective was to fix a frozen water problem in a laundry room addition. The fellow doing the audit offered to expand the objective to include a free total energy audit with solutions to other energy improvements that might be considered in addition the main objective of solving the frozen water line in the laundry room addition. Their total energy saving audit appeared to make sense but resulted in a cost more than I could justify. However the cost to just solve the frozen pipes in the laundry room addition was not of enough dollar value and needed to be added to some of the other recommendations to justify their involvement. I can understand their need to limit their involvement in jobs of a certain dollar value. However I just need a small portion of their total recommendation and will seek someone that can justify a small job..Some of the energy saving recommendations made sense and I may consider some of those recommendations in the future."

"He's a really friendly guy, very responsive to my calls, schedules me in partly because we've had a working relationship for like six years. He's done work at the house that I live in. He replaced a furnace there and the air conditioner. The day before the warranty of the air conditioner that he had installed ran out, he installed a new one and it didn't work either. He went to the local manufacturer's distribution and got a third one and it didn't work either so he went and got me a brand new upgraded unit and a discount for all the inconvenience. He's a good guy and I have no complaints whatsoever. Sometimes, some of the worker bees that he sends when he is on a job and somebody has to come and check something, they come right away but they are not necessarily as diligent as he is."

"This home inspector was great. Not only did he agree to drive all the way out to my future home in Spring Hill, he also showed up on time and conducted a very thorough walk through of the house. He also set up and coordinated with a termite inspection company so I didn't have to do a single thing. Overall his quote was also the cheapest out of every other company I looked at."

"Very well.  Morning Star referred me to a free energy audit as a Missouri resident which will provide a $400 credit to my utilities.  The windows installed were double pane Heartland windows.  I've seen a significant reduction in my electric bill this summer immediately.   The installers did a great job.  I will be asking for their assistance again to finish the remainder of my windows.

"Fantastic company!!! Mammoth removed my conventional HVAC and all ductwork while upgrading my home to an energy efficient split system.... which is amazing! My entire house is comfortable, the system is great and our overall energy bills have dropped! The Mammoth team were on top of their game and I couldn’t be happier with their service."

Energy Efficiency Auditing FAQs, answered by experts

Homeowners may qualify for an HVAC tax credit if they install an ENERGY STAR®-certified HVAC system that exceeds the energy efficiency minimum standards:

  • Split-System AC: 16 SEER2

  • Packaged AC: 15.2 SEER2 and 11.5 EER2

  • Ducted Split Heat Pump: 15.2 SEER2, 7.8 HSPF2, and 11.7 EER2 

  • Packaged Heat Pump: 15.2 SEER2, 7.2 HSPF2, and 10.6 EER2

  • Mini-Split System: 16 SEER2, 9 HSPF2, and 12 EER2

You can claim up to 30% of the cost of the job, subject to maximums.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

No, it isn’t necessary to have energy-efficient windows. However, if you care about your energy bill and making your windows more energy efficient, fixing any heat, UV, or air transfer issues is an excellent way to lower your bills and keep your house cooler in the summer and warmer in the winter.

It’s not recommended to turn off your breaker box in hopes of saving electricity. Breaker boxes were not designed to constantly be switched on and off. Therefore, turning off breakers unnecessarily can cause costly damage that outnumbers any energy savings. Only flip your breakers if absolutely necessary when troubleshooting an electrical issue.

Not all homes are suited for solar panel systems. Older roofs or those in poor condition may need repairs or replacement before solar panels can be installed. Some other factors to consider are the amount of sunlight your roof receives, the roof’s orientation and pitch, and any shading from nearby trees or buildings.
