I recently had my roof replaced by Stellar and the whole process from beginning to end was outstanding! After a severe hailstorm in my neighborhood there was a constant flow of roofing companies knocking on doors. Despite having many choices a friend personally suggested Stellar to me due to the fact that they are trustworthy and the quality of work they completed on his house. Communication throughout the roofing process was great as I had many questions and the disruption from the install was minimal. The total process was very professional and timely and I could not be happier with the the finished job! I have already recommended Stellar to another friend of mine and will continue to do so.

Very happy with the whole process with Stellar Energy Contractors from getting the estimate through installation of our solar panels. They were the only company we have found in several years of searching who were willing to work with our stone coated steel metal roofing. Communication and workmanship was excellent and professional. Only a 2 month turn-around from the time we contacted them to the day that our installation was complete. Highly recommend!!

One of our inverters went out on our solar panels. the installer was no longer in business. I contacted Stellar Energy. My router was not receiving input to verify failure. They did several consultations and e-mails to figure out the problems. Sent the info to fix the readings and even arranged for a new inverter to be sent to replace the old one. All of this was done at no charge, even though it was fairly complicated to figure out everything. I was very impressed. I certainly plan to use Stellar Energy when I install more solar panels even although I live in Pueblo. Top notch people to work with.Regis

Stellar Energy Contractors designed and installed a complete solution to our A/C (/heat pump) needs for two bedrooms and a common area. The units run efficiently and quietly! Their installation team was creative in solving challenges that arose and would not "sign-off" until everything was working to our satisfaction. They were flexible in their scheduling (to accommodate our scheduling needs).Service: Install AC

Stellar Energy did the original installation of my solar array. During the initial sale they were eager to contact me and worked well to get me a system. They encouraged me to make several changes including using microinverters that handle each panel independently. They original installation went well and the system worked well for about a year. The best part was the monitoring capabilities which have allowed me to see problems with individual panels in the system. When there started to be problems with some inverters Stellar came out and fixed them under the 10 year warranty they had. However, during the past couple of years the service has changed. Last year they started charging a travel fee to come down and install the warrantied inverters and I did not think much about it even though it took a long time for them to schedule the service and make the repairs. This year things have gotten worse. I have been in contact with them for over three months about issues with inverters and they have been extremely bad about returning calls and still have not scheduled the service even though they have indicated they have had the replacement parts. During the past month have called a number of times to check on the status and when I have talked to someone they promised to schedule the service and call back very soon, but would be charging both the travel fee and an hourly service fee. So far I have not had a call about the status and a schedule for repair. Through all this issue I have had a significant reduction in panel output that will cost me in my lack of net metering surplus this winter. If I had it to do over based on the increasing cost for service and lack of communication I would do more research on the vendor and probably choose a different company.,

Many issues with using this company. I really don't like to leave negative ratings but I believe some deserve it. Stellar was subcontracted to install my solar system I purchased from lifeTime Solar. I will address my issues with Stellar only.1. Lack of coordinated communication. On a couple of occasions, they either didn't show up when planned or showed up unannounced or very late. This caused scheduling issues with my time.2. The micro-inverters installed where not the ones called out on the permit and sales order. I caught this when I verified the equipment that was installed. This was a failure on 2 occasions, A. Ordered wrong part and B. Failed to catch the problem at the site when the equipment was delivered and installed.Of course I was told it was an order mistake but I have a suspicion it was the other inverters where cheaper. They did correct it after I pointed it out. How many people crawl up on the roof and verify the equipment?3. The inverters initially were wired incorrectly inside the combiner box and I had to insist they check this out before they test it. They were wired incorrectly and they did fix it. This is pretty sloppy in my opinion.4. Even after I instructed them on how to access my roof to avoid my gutters, they still managed to damage the gutters installing a broken panel.Conclusion. Since I don't have another company to compare to, this may be minor stuff, but Item 2 and 3 really irks me in that they didn't catch the problems, I did. If you can't verify what is getting done, get someone who can independently verify it if you decide to use Stellar.

The Stellar team is great to work with. They are responsive, honest, and take pride in their work. We worked with Brennan on a ductless mini-split setup. The job was certainly complicated and Brennan and team did a great job installing the product. Most importantly, it is clear that they take pride in their work. The job took a bit longer than anticipated and it would have been easy for them to cut corners to speed things up...but, they did the job right even though it took longer. I highly recommend Stellar for their professionalism, competitive pricing, and positive attitude.

I'm happy with the end product in terms of the solar panels and installation and the company they subcontracted the installation to (Epic Solar & Electric) was great to work with.However, Stellar has been horrible to work with from a communication and project management standpoint. There were numerous considerable delays in the project and they did not communicate well at all about them. I had to initiate contact to get answers on when things would get done.Solar panels are a commodity now and you can find the same hardware from numerous companies in the area. If you have an alternative to Stellar, I'd recommend pursuing it.

After having an independent energy company (that does no repairs) assess my home for heating leaks and ways to improve energy efficiency, I hired Stellar Energy because they were on their list of recommended contractors. I attempted to get an estimate and then schedule the work-it took months! Yes, they would "forget" to return my calls or the individuals who were supposed to switched to their solar division and never had anyone cover their work. I should have learned my lesson then, but as I thought I was getting an unbiased referral (though I found out later that the owner of the independent energy company and the owner of Stellar are outside friends) I still went ahead. When they came back to schedule me, they seemed appalled that the first estimator "missed" a lot of the necessary work-after he was billed to me as a "professional energy engineer." This is or a project of over $11,000-and the price got higher!! They work was eventually done (this took 6 months) though after holding on to my 50% deposit for months before starting. As other reviewers have noted, the day they finished when I asked if they could invoice me, money was demanded on the spot. They hadn't finished cleaning up or allow me to complete the inspection of the work. Perhaps the most egregious is that they (Stellar) submitted to receive the energy rebate (for themselves) and not for me. I was never given any of the paperwork I would have needed to obtain those rebates. I tried to contact and review with Tom Wilkinson (?owner, president) but in his patronizing and condescending way basically blew me off. I won't going to post a review at all but they offer a 1 year warranty which increases to 5 years if you post a review. Given their poor business model (they say they demand instant payment, and obviously hold onto your deposit for months) to pay suppliers, I can't imagine they will be in business much longer. Buyer beware, stay away from Stellar!!

When I had my roof replaced in November, I contracted with them to take my solar panels off and put them back on. They managed to get my panels back on in June. Yes, 6 months later is when they managed to finish. They didn't work while the roof was being installed, like they said they would, so they removed some of my shingles to do their install. Unfortunately, they aren't roofers and they didn't do a great job putting my roof back together.It wasn't a great experience working (and waiting) with them. I don't recommend them, but if you really can't find anyone else, they at least did the job and my panels are working.

I used Tom and his team at Stellar to install a hot water heater, a whole house surge protector as well as solar (PV) on my roof to cover my whole house energy usage. Not only did we get expert advice we received a first class install, excellent communication all done by friendly contractors. Thanks Stellar team!

To be honest I am not happy that we worked with them.We spent about $10.000 for replacing our furnace and AC with Stellar and the first problem was when they finished the installation, they could not figure out how to setup the thermostat. We had to call them couple of times and not paying the whole money to them to force them come back and figure out how to set it up.Now, after about 18 months we have a little problem with the furnace so I called them a month ago and they told me that a tech will call me in couple of weeks. No one ever called.My wife called them again couple of days ago and the lady told my wife “the problem is that we do not have technicians”.I believe they need to be more responsible for their work.

2020 Update: My Solar System has been working flawlessly for the past 4 years. I owe a debt of gratitude to Tom and the Stellar Team for their excellent workmanship.I want to thank the entire Stellar Energy Contractors team for the excellent job they did with the installation of my solar power system,

In January 2012, had a hot water thermal solar system installed by Stellar Energy. It has had a few small problems as these systems often do. Such systems need to handle the complexities of pressure changes from drastic heating and cooling. However, Stellar Energy has stood behind their work in every way and fixed whatever needed fixing, even several years after installation. I recommend them.

Stellar Energy went beyond our expectations in doing an outstanding job for us. They replaced our rood and our air conditioner. They were very professional, very efficient and plus they cleaned up after themselves. They are a top rated company as far as I am concerned. I recommend them highly!

I have used Stellar as a Sub-Contractor on a dozen Solar projects and I must say, they are top-notch. They are in constant communication with me and our mutual customers, schedule projects in a timely manner, and do quality work. I highly recommend Stellar Energy.

Stellar Energy installed a faulty solar system. They are no longer in business to come out and repair it. Tom Wilkinson was their CEO. I suppose he starts a new company that installs bad/faulty products, then goes out of business and starts a new business. I'm reporting him and Stellar to the BBB and to the state electric board.Service: General construction

I found Stellar Energy Contractors through Xcel as I participated in Denver Energy Challenge. I had Stellar upgrade my HVAC units (furnace, a/c & water heater) and my attic & crawl space to make my almost 40 year old home more energy efficient. As in most projects, yes there were a few minor hiccups but I would still give my 2 thumbs up &/or 5 stars! Steallar followed through all aspects of the project (from providing estimates, coordinating the schedule around me, getting the work done & making sure I get all the rebates I'm eligible for). Everyone I met either in person or by phone were very courteous, friendly & very knowledgeable. Plus, I think it's awesome that they have this membership program to their valued customers (at no cost at all!) that provides discounted maintenance, repair & additional projects. How cool is to be able to entrust someone for continuous care!!!

I was not impressed at all. I had Stellar Energy do an energy audit in an older home I just purchased. I was hoping to get some good ideas on whys to improve my homes efficiency. What a waste of money even with TRYING to get $200 back from Xcel. They auditor came and was friendly. Went through and did some tests, and what not. Then goes on to tell me that I need to update all my appliances to the most efficient appliances on the market. I know my water heater, which is a 5 year old, 50-gal type, isnt the most efficient, but he is telling me I have to swap it out for a $5k-6k model that is the most efficient. I had just replaced my water heater in my last house a year before with a high efficient tankless for just under $2k. He basically said that about all the appliances and of course to replace all lights with LEDs. So basically spend $40k so that you can save $100 a year. Then the report came in 1 week later. Wow. What a joke. It had a few pictures and suggestions, but most of it was just a generic report with generic suggestions and random photos. The auditor was then suppose to come back to the house and review the report with you. I never heard a thing back from them except to pay the bill.Then as far as the rebate, they have been no help at all with getting the rebate form or filling it out. I will not be going back to Stellar for anything again.

We had Stellar Energy do an energy audit on our home in the spring as our house seemed to be a sieve for cold air in the winter, and an darn turkey roaster in the summer. Robbi their auditor, was very nice and showed us many things in our house we could do to improve efficiency. We chose to have the attic air sealed right away to help keep the house cool during the summer. This paid off right away as we were able to raise the temperature we set our AC at during the summer by 4 degrees. May not seem like much but the upstairs rooms were noticeably cooler in the summer months. Then in the fall, we had them dense pack insulation in our basement walls to prevent our basement from being an icebox. Not only did this warm up the basement considerably (from about 50 degrees in the winter to 67 degrees) it solved the problem of our pipes freezing in the kitchen above the basement. We docked a star because the scheduling of the work was cancelled a couple of times, and a little chaotic to reschedule, but we would definitely use them again. The insulation guys did a terrific job and the work was completed in 2 days for each job. Thanks guys!

Solar panels installed. Monitoring doesn't work. On new installation they took 3 months to activate monitoring after following up for atleast 10 time. Then after reinstall following roof replacement, the monitoring is still down after 14 months. No one answers phone now. Emails went unanswered.Service: Installation

5 stars for Tom and the crew (especially Reuben) for outstanding work and service designing, replacing and upgrading 2 HVAC units as well as supervising our attic sealing and insulation. The job was complicated but was done efficiently, professionally, and without a hitch. Tom did a thorough final walk-thru to insure everything was perfect and met his high standards.Would highly recommend without any reservation!

I contracted them to replace my windows. The installers were excellent. They even came out on Sunday, because they were so busy, to finish the job. The windows I bought are outstanding. The improvement to our home is noteworthy. The service people came quickly to remedy a problem. Cudos to Mike Mendes and his team for a job well done.

Only company we could find that combined a unique, but important, competency in HVAC, energy efficiency, renewables, and electrical areas. Provided this for a very reasonable price as well and their customer service was outstanding. Highly recommended. We will be calling them again.

A big thank you to Stellar from start to finish on maximizing our home energy efficiency.They kept us informed and were so helpful along the way. Would recommend to all!

"My husband and I cannot say enough about how pleasurable it was to work with the folks from Stellar. We had a hail insurance claim that covered our roof and windows. Stellar handled it all, they negotiated with the insurance company to get our windows properly covered (the first amount was not even close), the window installation was completed in one day and turned out great, the roof install was CLEAN and smooth (they left no trace), and the communication was great (we were always informed on the project status and schedule). Since we had so many hail claims in our area, I can state that the majority of our neighbors just had an average experience while ours was GREAT! Thanks Stellar.

We received a prompt response to our inquiry and set up a consult. Micah came to our home to take some notes and photos. Unfortunately that’s where this ends. After three weeks and multiple contacts with the staff they cannot produce a bid for the work. We are going forward with a company who wants our business.
