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.

Does Patriot Pros offer warranties on new installations?

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?

Our team performs a professional load calculation. This takes into account your home's square footage, window orientation, and insulation quality to ensure your new AC installation provides perfect cooling without wasting energy.

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.

Patriot Pros Parker and Daniel showed up early and did a great job. Parker had originally come out to figure out what the problem was and he was worried about how high the pressure was. We needed a new pressure relief valve. My sister and I were a little concerned about the price and wanted a second opinion. Dad has used Patriot Pros for years. My sister talked with the owners while I made Dad delay so I could get a second opinion. Even with my sister and I being difficult, they were patient and professional. They explained what needed to be done and why to my dad a second time. I greatly appreciate them taking good care of my parents and would highly recommend them.
