Behold the Difference! Every day we are invited into our customer’s homes. Into their safe place and sanctuary. Quite often this is in the midst of a concern or issue that needs to be fixed! With an extensive background that spans well beyond just the trades, we love to be different. In addition to decades of industry experience, we bring some secret sauce - we love to take all the time needed to help, to make sure you are comfortable, and to provide amazing solutions. Come BEHOLD the difference! "Unfortunately we do not service or intall swamp or evaporative coolers".

"My water heater had gone out and called and called around trying to get quotes and big company’s were trying to schedule in person quotes which I know is a strong arm to get the work done then and there because they are already at your house ect. But with Behold I had a personal direct text from them asking about my situation and all I had to do was give some info send in pictures and voilà! They gave me their quote(2300$) which also beat all the company’s(3k$+) I had heard from! They had a tech out to me ASAP. It almost could’ve been same day but I was in no rush. Hunter came in and did it all him self of removal of old and installing new in just two hours! They are great to work worth and will definitely recommend and go to again."

We are your local go-to plumbers and HVAC guys! We can handle all of your plumbing and heating and cooling needs with one phone call! We will always give you a detailed diagnosis and clearly explain what repairs we will do. Experts by trade, competitive in the market and quality work is who we are! Call us today to schedule an appointment!

"Mile High Plumbing and Air has been game-changing for us. John and Osh have now done two jobs for us and we couldn't be more pleased. The first project was a complicated correction of poor hot water circulation to our entire home. They also replaced a leaking expansion tank and fixed a finicky shower handle as part of the first project. The second project was fixing a leak from a tankless water heater and at the same job fixing a plugged sink. They are efficient, prompt, courteous, and extraordinarily knowledgeable. We manage rental properties and, although their first work for us was for our personal properties, they are now our go-to plumbers for every property - personal and investment. Seriously grateful we found them. You will not find a better company."

"Polite enough, but not very responsive with follow-up texts and scheduling. Inconsiderate of damages done to the home while completing his tasks (unnecessary demo in the basement, severe scuffing of hardwood floors during radiator repairs, etc). Left old pipes and trash from a job for the homeowner to dispose of. Installed new garbage disposal WITHOUT power cord; small appliance is not able to be used and drain now clogged."

"Jason and his apprentice came to replace our garbage disposal. While Jason looked nice and professional, the entire work was done by the young apprentice who finished the job without locking the garbage disposal. Three month later water started pouring down and the entire garbage disposal simply fell off and dropped. I called and the lady who answered the phone argued with me that it was their fault and said she would forward the message to Jason. Then I have never heard back from them. Bad experience and I do not recommend them for sure."
