In Phoenix, AZ
When Is It Time To Replace My HVAC Equipment?
Air conditioners that have a seasonal tune-up are properly maintained can last a long time—but as the saying goes, nothing lasts forever. When it comes time to replace your existing AC unit, Sun State HVAC brings decades of experience and installs most major brands available today.
But how do you know it’s time to replace? Here are key factors we use to help homeowners decide:
1. Age of the unit:
While age isn’t the only factor, it’s a key part of the bigger picture. Systems 10–15 years old may still be viable if maintained, but even 5–8 year-old units can be on their last legs if neglected. A full system inspection can determine viability.
2. System Controls
Have system safety or efficiency controls been bypassed or removed over time? If so, the integrity of your unit may be compromised — and it may be time to consider an AC unit installation in Phoenix AZ to restore full safety and performance.
3. Coil Condition
Check for physical damage like hail dents or corrosion. Damaged coils reduce efficiency and increase operating costs. In some cases, air conditioner replacement in Phoenix AZ may be more cost-effective than repair.
4. Antiquation
By year 12, older AC systems begin falling behind modern efficiency standards. By year 15, the tech has usually passed them by. New systems can save 30%–40% in energy costs—especially when upgrading through professional AC unit installation in Phoenix AZ, ideal for homes planning solar power integration.
5. Reliability Concerns
Old systems often come with costly breakdowns and recurring small repairs. They also tend to fail during summer heat waves—right when you need them most. Planning ahead with air conditioner replacement in Phoenix AZ helps avoid discomfort and high emergency costs.
6. Refrigerant Cost
Systems using R-22 refrigerant (Freon) are costly to recharge due to its phase-out. In summer, it can cost $250 per pound or more. While alternatives exist, they require extra labor and are still temporary fixes. A complete AC unit installation in Phoenix AZ may be the smarter, long-term solution.
7. Bottom Line
If your system is over 12 years old and repair costs exceed 20% of a new unit’s price, air conditioner replacement in Phoenix AZ is usually the best choice. It’s not just about cooling—it’s about comfort, energy efficiency, and long-term savings.
