If you have any plumbing, heating, cooling or electrical issues at all, contact the experts at High 5 today. We are highly experienced and extensively trained. Using state-of-the-art equipment and a comprehensive understanding of plumbing and HVAC, we handle all of your needs in a timely and professional manner. Whether you need to install, repair, or replace piping, unclog a toilet, replace your ceiling fan, repair an electrical box, install a new air conditioner, need furnace maintenance, or more, they can handle it quickly and efficiently. With High 5, you can count on their expert plumbers, electricians, and HVAC technicians to show up as at your home on time and ready to work. We are well-known among their customers and neighbors for our ethical and honest mode of operation. Many other companies take advantage of their customers’ lack of experience and provide low-quality services at exorbitant rates. At High 5, we've built our business based on honesty, integrity, quality work, and exceptional service at fair pricing. Because of these values, it has allowed us to employ the best of the best in our professional fields. Contact us today and schedule an in-home cost estimate for your plumbing, HVAC or electrical in the Denver area. We proudly offer a Senior Discount and Military Discount of 10% off up to $100.

"Over 7 weeks AND 13 visits, we were intermittently subjected to gas leaks, water leaks, no hot water or heat and error codes on our tankless water heater. They took advantage of the fact that my 2 teenagers and I had no hot water and no heat and continuously up-charged us. During that time, they charged an extra $1900 over the original estimate of $4000. All of the issues were because they failed to recognize that my existing venting didn’t match the new unit (even though they added to the venting) and because they didn’t provide drain piping to manufacture recommendations. They offered me money back and then rescinded the offer as the problems they should have caught just continued. I ended up “chatting” with the manufacturer and showing them screenshots to prove the venting was wrong. They offered a cleaning crew after I complained and already cleaned up the mess they ground into the carpet. When I asked to speak to the owner/DORA license holder, Levi Torres, I was told Levi “doesn’t take phone calls”. Clearly, he only takes your money and wastes your time."
