About
We are a full service Home Performance Contractor.
We begin our interactions with customers with a no cost evaluation of their homes that includes a blower door test, thermal imagery, air flow testing, and a detailed inspection to focus in on the root causes of the problems they seek to correct in their homes. Simply put, our diagnosis leads to a solution of the right problem, not selling you a product. Once we determine the right course of action to solve the problem, we can perform the work too!
The most enjoyable part of our job is to hear customers say things like,
"I didn't know that about my home!"
"Why didn't my heating and cooling professional tell me that?"
"I didn't even know that could be fixed."
We have the ability to solve comfort issues in homes that nobody else can solve...Things like:
-Hot/Cold Rooms- -Drafty areas- -Dusting too often
-HVAC running 24/7- -High Utility Bills - -Cold Floors
-Musty Odors -Wet Basements -Nasty crawl spaces

Comfenergy did a very thorough consultation and showed us many areas we could improve. We elected to do our attic insulation, have a bathroom vent redirected, and update the insulation in our unfinished basement through them. They got the job done very quickly.

Comfenergy did a thorough job of assessing and fixing our insulation problems. Robert Guzman was our foreman, and he was a pleasure to work with, and very professional.

Comfenergy did an amazing job. The crew was extremely professional, courteous, and efficient. The work was done in the promised time-frame. In addition, the flooring added to the attic is beyond what I expected in appearance and capacity.

We had a rather large mixed project of renovation and basement build, which included just about every craft trade; and Comfenergy pulled all the pieces together for us. They did a good job cleaning up along the way and afterwards, we also received a certificate for a cleaning service. Comfenergy kept the job site safe throughout my project. Since we were still living/working in the house during the project, there was constant communication to make sure everyone knew what was going on. We were in constant communication via email, phone and text with the John and all of the workers. I am satisfied with the quality of materials used. All of the materials were of great quality. I am satisfied with the quality of the workmanship. With this large renovation there were very few things that needed attention, and Comfenergy did a great job addressing them to make sure the final product was to our satisfaction and remained professional throughout my project. John and all of the workers were very professional, realistic and organized. Expectations were managed upfront and each part of the project was executed a balanced order. We had several phases to our project to ensure life balance during the construction. Our schedule was flexible and they worked with us every step of the way to get things done safely and correctly. There was a lot of work and scheduling that went in to our project. And so far with some of the hot/humid days that we've had, the house is comfortable and their are no signs of duct sweating in the walls. John went above and beyond for our family to make sure everything was done right so we won't have any future issues. He treated us more like family than customers, and made sure we were happy with everything. Comfenergy came up with a great plan and they were flexible with us when we wanted to add things along the way. We were in constant communication and all of my thoughts, ideas, concerns, questions were received, thoughtfully discussed and executed well.
Comfenergy's reply
I am very happy to receive this review. The project was beyond the scope of what we normally do, and there were a few times where we relied on the patience of the home owners to allow us to come up with solutions. I wish that every human being I came in contact with was as easy to get along with as Earl, his wife and daughter. It was a joy to work on their home. So happy that they are pleased with our efforts! Gob Bless

Shayne with Comfenergy provided us with a crawl space repair estimate about a year ago, and we were finally able to schedule the job.The work on our crawl space was very specific and Shayne came back with exactly the solution we needed.The day of the job, the crew manager Brent and his team did a phenomenal job! He was very thorough and explained every step of the repair. The change from before to after was a literal night & day difference. I still cannot believe the temperature difference in our house. Comfenergy came highly recommended by our good friend, and we are SO glad we chose them! I would recommend this company to anyone with energy issues or crawl space issues at their house. Thank you Brent & Shayne!

Mr. Adler: We will pass your comments along to Shayne, Brent, his team and others here at Comfenergy that worked to provide you with an experience that you feel good about. Thank you for your kind words and your business
