Project: Test Indoor Air Quality

Very up front and professional..easy to work with. The workers were polite and explained things well. I felt very comfortable with this contractor and not intimidated as others tend to do.

Erik G.

The job was done well and quickly. Since my lines only freeze in the winter, only time will tell if the project was successful. Fingers crossed and thank you!

Dennis R.

I appreciate the process of evaluation and options listed in benefit order. It makes decisions much easier and better. 

Bernard R.

Everything was perfect.

I want to pass along to the Boss that the workers you sent out to my job (Eric & Brandon) did a great job and were a pleasure to deal with! We were very pleased with their work and them over all.

Jeffery R.

Just an FYI. The guys were here this morning and did a great job. Very professional. Cleaned up everything. Couldn’t be more pleased. You run a good business! Thanks!!

Please let us know if there are energy rebates available. Thanks for your promptness in meeting our need and working into our schedule.

Efficient job. took great care in protecting flooring and furniture. Took time to review what services were done. Polite, personable installers & they tolerated my dogs which is a big plus!! Looking forward to the fruits of their labor (i.e. lower utility bills!)



  • Keith Williams,

    My wife and I purchased a leaky and minimally insulated older home and knew we needed to upgrade our insulation and have some air-sealing done. As a former home inspector who has also taken BPI/RESNET (weatherization) classes myself, I knew exactly what I was looking for in a weatherization/insulation company, and Energy Smart was it! From my initial inquiry to follow-up after the job, Jon and his team at Energy Smart took the time to do things right and provided both before  and after blower door tests to analyze the performance and effectiveness of their work.
