How long does an AC installation typically take?

Most residential air conditioning replacements are completed within a single day. If your project requires extensive ductwork modifications or a complex system configuration, we will provide a detailed timeline during your initial estimate.

Will a new AC unit really lower my electricity bill?

Modern cooling systems have much higher SEER2 ratings than units manufactured a decade ago. By switching to a high-efficiency model, many homeowners see a noticeable reduction in their seasonal energy consumption.

Every new system we install comes with a manufacturer warranty on parts. Additionally, we provide our own labor guarantee to ensure you have total peace of mind regarding the quality of our workmanship.

How do I know what size AC unit my house needs?

Reasons to Consider AC Replacement

Deciding between a repair and a full air conditioning replacement often depends on the age and reliability of your current equipment. Modern systems offer significant technological improvements that can enhance your daily living experience. Understanding the signs your air conditioner is going out can help you plan for an upgrade before a total system failure occurs.

System Age. Units older than 10 to 15 years often lack the efficiency of current models and are more prone to mechanical failure.
Frequent Repairs. If you find yourself calling for service multiple times a season, investing in a new AC unit is often more cost-effective.
Rising Energy Costs. Newer high-efficiency systems use less electricity to cool your home, which helps lower your monthly utility bills.
Inconsistent Cooling. Difficulty maintaining a steady temperature or managing humidity levels often indicates a system that is no longer sized correctly for your home.
Regulatory Compliance. Navigating the 2026 high-efficiency rules in Colorado is essential for homeowners, as new standards for emissions and performance now impact equipment availability and installation requirements.

Jeremiah and Parker were real heroes! I called Patriot Pros in a complete panic as my water softener started gushing water and I couldn’t stop it. They came within 20 minutes. They figured out what was happening and gave me options as to how to proceed. They were very clear and I understood exactly what to expect. They cleaned up the mess that the gushing water had made and left fans to speed up the drying process. I can’t thank these guys enough and I can highly recommend them as plumbers and great, polite and professional guys.

There are few words to express the absolute professionalism, respect and service I got from both Jeremiah Gray and Rhett Parker Mudge. Their service was far beyond what I would ever expect to receive from two technicians whom I have never met. Everyone knows that calling up a company to get work done is daunting and you never know if you’re going to get taken advantage of or not. Jeremiah and Rhett were completely forthcoming and honest when quoting me for a potentially large and costly job. They took no shortcuts in diagnosing the problem with my septic tank and giving me realistic insight into what the job entailed and how much it would run. They provided me constant updates to include pictures and findings while at my house looking at the septic tank. I called two other companies before using Patriot Pros and did not receive the level of customer service or care that Jeremiah and Rhett provided me with. It is absolutely necessary that we as a society stop to honor and commend the men who provide quality care and service when it is not commanded in our current world. Furthermore, we must deliberately defend and rigorously endorse those who provide quality craftsmanship in an age where the mundane and crooked so often are the first encounter when help is requested. Rhett and Jeremiah walk among us as men, more than likely without ever asking for consideration or pause…. Today I honor them with this review in that many will read my words and decide to invest in more than mere words or slogans from a company… Rather that they too may receive the level of virtue and warmth that Rhett and Jeremia bestowed upon my home and my septic tank. God speed to these two men ….

Jeremiah and Parker were so professional and kind. We recently had a home inspection in which a septic issue was brought up, but was not made clear. When Jeremiah and Parker evaluated the issue not only were all my questions answers, but they were clear and concise. They went above and beyond to evaluate the issue and actually ended up saving me so much money thanks to their honesty and hard work. Absolute quality service was provided. Thank you so much!
