Most of Centennial’s housing stock was built between the 1970s and 1990s, and the original AC systems in many of these homes are either at or well past the end of their useful service life. A 15 to 20-year-old central air system may still be running, but it is almost certainly running less efficiently than it should and is increasingly prone to mid-season failures at the worst possible time. WireNut services, repairs, and replaces central air conditioning systems throughout Centennial with honest diagnostics and upfront pricing on every visit.

For AC repairs that can be resolved without full replacement, our air conditioning repair team handles the diagnosis and fix. When replacement is the right answer, our air conditioning replacement team handles the full installation. Regular maintenance through our AC maintenance service keeps systems running efficiently between repairs. See all Centennial HVAC services we offer.

• AC repair for systems that are not cooling, cycling short, making unusual noises, or leaking refrigerant in Centennial homes.
• Spring tune-up and maintenance before cooling season to clean coils, check refrigerant, and confirm the system is ready to perform through summer.
• AC replacement for systems that are past their useful life or that can no longer cool the home effectively despite repairs.
• System sizing evaluation for Centennial homeowners replacing equipment to ensure the new system is correctly matched to the home’s current layout and insulation.
• Thermostat and control diagnostics for systems that are not responding correctly to thermostat settings or that are cycling on and off without reaching the set temperature.

Here are the air conditioning services our Centennial technicians handle most often.

How Long Should an Air Conditioner Last in a Centennial Home?

Central air conditioning systems in Centennial homes typically last 12 to 15 years with proper maintenance. Systems that have not been regularly serviced tend to reach the shorter end of that range, while well-maintained units in homes with clean filters and annual tune-ups can stretch to 15 years or slightly beyond. Centennial’s dry climate and the UV exposure and temperature swings that come with Colorado’s elevation put more stress on outdoor condenser units than milder climates do, which also affects longevity.

If your AC system is approaching 12 years old and starting to have repair needs, the repair-versus-replace conversation is worth having before you put significant money into the next repair. WireNut gives you an honest assessment of your system’s remaining useful life and what replacement would cost so you can make an informed decision rather than guessing.

Why Is My Centennial Home’s AC Running Constantly but Not Cooling?

An AC system that runs continuously without bringing the home to the set temperature is usually dealing with one of several issues: low refrigerant from a leak that has reduced the system’s cooling capacity, dirty evaporator or condenser coils that are preventing efficient heat transfer, a system that is undersized for the home’s current cooling load, or ductwork leaks that are losing conditioned air before it reaches the living spaces. In older Centennial homes where the system has not been serviced in years, dirty coils are one of the most common causes of this symptom.

WireNut technicians check refrigerant charge, coil condition, ductwork, and system sizing as part of an AC diagnostic visit. You get a clear explanation of what is causing the problem and a flat-rate price to fix it before any work begins.
