The Facts on AC Replacement

Most central air conditioning units can be expected to last between 15 and 25 years before AC replacement is in order. If the AC unit at your home or business has started experiencing significant AC maintenance problems or needs frequent repairs, the knowledgeable technicians here at Sun Tech Air Conditioning can help you determine whether it's time to take advantage of our professional air condition replacement services to update your cooling system.

Timely AC Replacement is Critical

Over time, even high-quality AC units start losing efficiency and consuming more energy, but these changes are often so gradual that most homeowners don't notice the slight increases in utility costs and the decrease in indoor comfort. The good news is that many of our customers report lower energy bills and improved cooling power after their air condition replacement projects. A new, modern AC unit may also boost property value and may even make your home more attractive to potential buyers if you're planning to sell in the near future.

A Proud Team With Proud Customers


I've used Sun Tech three times over the past two years. I was a bit leery at first, as they were sent via a home warranty company. However, the professionalism of the techs, and the company employees themselves quickly erased that trepidation. We had no AC in the Arizona summer, and their tech and company made us more of a priority than our warranty company, rushing to get our fix made. They tried everything they could to keep our unit working. After working with them, and realizing the age and failure rate our unit was having, we decided to get a brand new HVAC unit. Our family did not even bother shopping around, as we knew the care and quality Sun Tech had given us already."


Phoenix, AZ


We were assigned Sun Tech from our warranty company. They notified us very quickly and had a tech out ASAP. Upon review, they were able to diagnose and tell us what was needed to make out unit run right. We got the estimate and a couple days later the work was done. The two installers we prompt, courteous and let us know everything that they would be doing. Our repair was done in the timeline that was quoted and our A/C feels like it is brand new. Could not be happier with Sun Tech and we will for sure use them in the future."
