We purchased a new home in '21 and knew we wanted to do at least three things right off the bat: 1)…read moreinsulate the attic, 2) install solar, and 3) an EV charger. I was pleased to find that REenergizeCO did them all and were more than just an installer but on mission to increase energy efficiency. From start to finish communication was fantastic. They first did the insulation and we noticed a difference almost immediately. They also took care of submitting the Xcel rebate paperwork for it. The solar panels and EVSE came a bit later. Again, they took care of all the paperwork with Xcel. The system has been working without flaw since and saving us tons of money in this inflated energy cost environment. We had them out recently to detach and reset the panels for a roof replacement. They took the opportunity to slightly tweak the layout for better efficiency. Still the same commitment to quality!

That is not the norm when interacting with the trades. My HVAC system had a pipe break and it was leaking water over electrical cords. This was an electrical hazard in the making. The leaky pipe was spilling water all over the play yard of my dog training facility. My team could not use the space, as the water was growing an ecosystem and the dogs wanted to lap it up like a kale fruit drink. Hello giardia! Sean noticed that our HVAC system was not sealed, so we were essentially heating and cooling the outside. They sealed what needed sealing and replaced our air filters. My understanding is that the team primarily does insulation in Denver, so they can help with that, too. Drug-free crew...no meth mouth. Hire these people.

I couldn't be happier with my choice to hire Mark and make this energy investment in our home. I…read morewish we would have contacted Mark before spending thousands on HVAC upgrades, thinking that would make our home more comfortable. As it turned out, we had lacking insulation in our attic and no insulation at all in our exterior walls. Mark presented us with several options and guided us toward the option that would have the most immediate impact and fit our budget. He filed all of the paperwork for the Xcel rebate. While Xcel took quite a while to process the rebate, it ended up being substantially more than I was expecting and certainly help offset the costs improving the insulation throughout our home. Before the improvements, the second level of our 2-story home was significantly hotter in the Summer or colder in the Winter, than the main floor. Now, we have consistent temps throughout the house and are seeing lower Xcel bills too. Mark and his assistant were courteous and professional throughout the 2-day job and very Covid conscious as well, which was appreciated. Highly recommended!!!

Now, adding to the scores of five-star reviews on Airtight Energy Inspections! Stuart came to do the audit this morning and I was so impressed at his knowledge of how to improve the efficiency of our 1926 Wash Park Bungalow. He even talked me out of spending $15k+ on new storm windows, giving me much affordable options that will yield better results. In addition to all of his recommendations, he is getting me a $40 annual credit with xcel at no cost to me. Among other things, he discovered that our bathroom is venting into insulation in our attic (a risk factor for mold) and that our sunlight needs to be sealed. Will be recommending Stuart to my neighbors!

The lady I spoke with, who's name I've forgotten, was extremely helpful. After spending a bit of time asking questions to understand our project and needs, she went told me that she wasn't aware of the any rebates but that she'd look into it and follow up with me. Later than evening she called me and confirmed there were currently no rebates, and concluded that it didn't make any sense for us to have them audit our home. The way she put it was roughly "we don't like to put ourselves in situations where we can't add value". I really appreciate the honestly and extra effort she made.

In fact, the old company did attic sealing for me and said it was all done, but when Robert reviewed the work, he found dozens of spots they hadn't sealed up. I cannot recommend them enough. I was quite confused by the rebates and the process and they made it all SUPER easy.

The inspection…read moreseemingly went well, but I was informed that there was no way to judge the age of the HVAC unit because the sticker that normally has that information was painted over. When I went to change the filter (I had a HVAC professional replace the filter shortly after buying the condo), I noticed that the sticker with the serial number and model number was in fact not painted over, but instead was right next to the filter. Recently, the unit has been acting up and I have been told it needs to be replaced because of its age. I do not expect Alpine to be experts in HVAC. I do however expect any general inspection to take a reasonable effort to find all the information possible about the various parts and pieces that were inspected. They failed to do this with the most expensive part of the condo. After going online and decoding the serial number and model number that they missed, I found that the unit is nearly 25 years old and is beyond the end of life. The purpose of inspection is to identify things like this so that I can ask for concessions at closing. Without that sticker, I had no way to do that. Now, less than a year after being here I am having to replace this special HVAC unit that will end up costing me over 20k. Final cost is yet to be determined. Alpine failed in their most basic of tasks.
