I called other places but when they came out gave me bid I felt comfortable with customer service and knowledge of my issue so I went with this company of course I was satisfied with time of completions and the work done. I highly recommend.

Seth has helped us with various electrical jobs and is so professional and reliable. He’s great at communicating what needs to be done and is trustworthy. Also, I love the online booking feature on his website. Highly recommend.

Wayne Brimm was very professional, kind, awesome at educating me and was so happy to answer all my questions. Thank you Wayne!! I highly recommend this company!

Highly skilled electricians at fair prices. Very efficient, quick scheduling. This is our go-to for residential repairs and installations. Our house is loaded with oddball / complicated / commercial fixtures, and Electri-serve has always done a great job. We have had a lot of problems with other electricians doing terrible work and are thankful for the work Electri-serve does for us.

They did a quality job at a very reasonable price.

Brian provided outstanding and very professional service.

I was very happy with the work that Jeremy and Chris did at my 1950's home in moving two electrical junction boxes and the electrical meter in preparation for solar install. The were professional and thorough.

Fantastic owner and great team. Very professional and great work.

Working with Mr. Lujan was the most rewarding contractor experience I have had. His knowledge and integrity are unmatched. HIGHLY recommended!!!!!!

Professional and prompt. The technician explained in detail process of new installation of heating unit (Goodwin). Look forward to doing business with this company. Thank you for your service and eval of the existing heating unit in my condo.

Per Denver City inspector Bryan's License expired July 2020, no current update licensing on file (2/4/2021 confirmed). Work did not pass inspection, collected all payments from owners and abandon project. We are to loose power to the building in the next 15 days.

I have used AAARK twice, first to service my AC and second to install a Aprilaire 800 Humidifier. Travis and Stu were the installers and showed up on time and did an excellent job installing and explaining the setup to me. The system needed a minor adjustment so Matt and Chad came out a few days later and made the necessary adjustments at no charge. Highly professional staff and I would recommend them to anyone looking for HVAC work.

I was impressed by the service I got when I called great guys to maintain my AC. They diligently took time to clean it out inside and outside. Checked the Freon. My AC runs super efficiently again.

I had Applewood come out to follow up on my home inspection saying our water pressure was too high. Pressure was tested and currently the pressure is right in line, so no changes were needed. Brian O'Driscoll was timely, professional and personable! He let me know what he was doing and gave me steps I could take in the future to prevent (or uncover) any issues down the road. Thanks Brian!

Very professional. Helped me find a possible diagnosis for an issue with my dishwasher hook up over the phone and promptly came out the next morning and fixed it.

An INCREDIBLY efficient and responsible company. It was an absolute pleasure to work with Top Shelf. We had a massive job that needed to be done with a complete rip-out and re-install of our Furnace. They also installed AC and upgraded our Electrical Panel. Financing was really easy and helpful and the entire process was painless. They're like a well-oiled machine and all the work was done incredibly quickly. I would highly-recommend them to anyone who needs this type of work (or any work) done.

Zach came out to replace and install a new furnace for us and did an amazing job! We have a small space to work with which is an accomplishment on its own that should be applauded and Zach made sure that everything was installed properly. Communication was good and overall would recommend! Thank you!

Tipping Hat is our go-to service for all plumbing needs we've ever had. They are incredibly knowledgeable and every single one of them are exceptionally nice and thorough. Today we had Brandon and Andrei. They explained the problems we are having with our furnace and water heater in depth and answered all our questions. This is a truly reputable company who you can tell takes great care in the quality of people they employ. Can't say enough great things about Tipping Hat.

The team at Geek it Together really enjoyed working with ESC. We look forward to continued business with them.

We have work with CSI on several different projects using back up Generators and UPS systems including Fire Stations, Call Centers and other commercial buildings. Their customer first approach and their level of expertise in power generation and critical UPS backup systems make them the best in the business in my opinion.
