Top Castle Rock AC Installations

Air conditioning systems aren’t engineered to last forever. Even with conscientious upkeep, you’ll probably need an AC replacement after 15 years. Summit Heating & AC offers customers in the metro Denver area an industry-leading warranty.

Other benefits include:
  • Indoor temperatures at more consistent level
  • Improvement of indoor air quality
  • Increase in energy efficiency
  • Decrease in monthly utility bills
  • Increase in property value

When you contact us for a no-cost AC install estimate, we’ll look at your ductwork, your insulation, your windows, and your other HVAC equipment. Then, we’ll make recommendations for an AC system that will be perfect for your house or place of business.

Having your new system installed by professional technicians will help to ensure that your new AC system operates efficiently. AC systems are complex, and they must be fine-tuned by service professionals who have been trained to do the task. Additionally, many manufacturers will void their warranties with you if your system is not installed by a professional installer.

AC Work Done Right


AC and heating costs amount to approximately 60% of your utility bills every year. If you’re considering an AC replacement but you don’t know where to start, we’ll be happy to help you evaluate new AC makes and models. Many of the newer models we’ve worked with will produce cool air and control humidity. This will help your interior stay more comfortable throughout Castle Rock’s humid summers.

Customer satisfaction has always been our very top priority. Summit Heating & AC makes this promise to all its customers: If you aren’t 100 percent satisfied, we’ll buy your system back. We’ll perform an extensive analysis at the same time that we’re installing your new system so that your system will run optimally. If you have any questions about efficiency ratings, required permits, or energy rebates, we’ll be happy to answer them. We can also explain the fine print in your manufacturer’s warranty and make sure that you’re eligible for manufacturer’s rebates.
