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.

Patriot came out this morning and we agreed to put in a new system. Their guys were here 2 hrs. later and by 7:00 pm we have cool air coming out the vents. All their guys were polite and did not leave a mess. When I was putting in my password in the Nest thermostat I kept messing up but Wolfgang was patient and kept helping me get it right. Great crew.

I called late last night about having no well water and our boiler not coming on. They called me back first thing this morning to say they were on their way. I told her I didn’t think they could get up our drive after the blizzard. She called her technician back to have him wait at the bottom of the driveway. We determined he could make it up with his vehicle, so he followed me to the house. Javier checked out our pressure valve for the well and found it defective. He replaced valve and got water restored. We found the boiler issue was related to the lack of water and were able to get the boiler back online. Very pleased with Javier’s help and knowledge. Great job.

My family and I were blown away by the professionalism of this company. They sent out a full team to replace our furnace and central air conditioner, and their work ethic was incredible. Each one was skilled and specialized. They worked tirelessly for three straight days, not stopping until everything was absolutely perfect. Every single employee was kind, friendly, and truly seemed to love what they do. This company is top-notch in every way.
