Is It Time to Replace Your AC? Here's What to Watch For

Don’t wait until your AC breaks completely. These common issues are signs it's time to call Randazzo for a free in-home replacement quote.

Your System is 15+ Years Old

Most air conditioners last 15–20 years. If yours is getting up there, a newer, more energy-efficient unit might save you money long term.

Strange or Loud Noises

Banging, rattling, or grinding noises can be signs of loose parts, motor issues, or other mechanical problems. These sounds shouldn't be ignored—they often signal a need for repair or replacement.

Excess Dust Indoors

If you're constantly dusting or noticing buildup around vents, your HVAC system might not be filtering air properly. It could be time for duct cleaning, a new filter, or an updated unit.

Poor Humidity Control

A properly working HVAC system should help regulate humidity. If your home feels too sticky or too dry, your system may not be operating efficiently or may be undersized for your space.

Inconsistent Room Temperatures

Hot and cold spots around your home could indicate airflow issues, aging ductwork, or an HVAC system that’s struggling to keep up. An upgrade can help deliver even, consistent comfort.

Frequent Repairs Needed

If you're calling a technician more often than you'd like, the costs can add up quickly. At some point, replacing the unit can be more cost-effective than constant repairs.

Frequently Asked

Do I need to replace my system, or can it be repaired?

If your AC is more than 15 years old, constantly needs repairs, makes unusual noises, or struggles with humidity or dust control, it may be time to replace it. Randazzo will inspect your current system and help you decide whether a repair is still practical—or if replacement is the better long-term investment.

Is the in-home estimate really free?

Yes—if you're looking to replace your air conditioner, Randazzo offers a free, no-obligation in-home estimate. One of our specialists will visit your home to assess your needs and recommend the right system. However, if you’re requesting a diagnostic visit for a repair (rather than a replacement), there is a $95 fee to inspect and evaluate the unit.

Do you offer financing?

We do. Randazzo offers financing options to help make your new AC system more affordable. With approved credit, payments can be as low as $95/month. Our team can walk you through available plans during your consultation.

How soon can you install my new system?

Most air conditioner installations are completed in one day, typically within 10 hours. We understand your time is valuable, which is why we pride ourselves on efficient, professional same-day installations whenever possible.

What brands or systems do you install?

We proudly install high-performance systems from Lennox and Mitsubishi, two of the most trusted names in central and ductless air conditioning. These brands are known for energy efficiency, reliability, and advanced technology.

Do you guarantee your work?

Yes. We back all of our heating, cooling, and electrical services with a 100% satisfaction guarantee. Our licensed, in-house team is committed to doing the job right the first time—no subcontractors involved.

Wouldn't hesitate to recommend Randazzo for any of your heating / cooling needs. Doug came out and was very kind and patient walking me through some things that were causing some issues with our A/C. Incredibly friendly.
