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."

Central a/c installations FAQs

If you’re replacing an old AC system with a new unit, you can usually clean and repair the old ductwork without having to conduct a full replacement. Cleaning HVAC ducts typically costs around $400, while repairs range from $200 to $1,000. In contrast, installing new ductwork can range from $1,000 to $5,000, making it far more costly than cleaning or fixing existing ducts. HVAC installation costs an average of $7,000 to replace a full system, so staying on top of maintenance and repairs is important.

AC cost efficiency depends on the size of your space and your long-term plans for your home. If you only need to cool a small area, a portable AC unit has a low upfront cost. Heat pumps are typically the most cost-effective option if you want to cool an entire home or improve the resale value. They provide strong cooling while being energy-efficient, which saves you money on your utility bills compared to most other AC types.

Installing a central AC unit typically takes four to eight hours if your home already has ductwork in place. However, if new ductwork needs to be installed, this can add another one to two days of labor to your project.
