Signs Your HVAC Might Just Need a Repair

Not every hiccup means you need to invest in a brand-new system. Many issues can be resolved with professional repair or maintenance:

Uneven temperatures in your home – Often solved by cleaning ducts, replacing filters, or fixing minor mechanical issues.
Unusual noises – Loose parts, failing motors, or worn belts can usually be repaired.
Reduced airflow – Sometimes as simple as a clogged filter or ductwork obstruction.
Short cycling (turning on and off frequently) – Could be due to a thermostat issue or a failing capacitor.
Higher energy bills – A repair or tune-up can often restore efficiency.

If your system is under 10 years old and has been well-maintained, repairs often make the most sense.

When It’s Time to Consider Replacement

At a certain point, repairing your system becomes more costly than it’s worth. Here are the red flags that suggest it may be time for an upgrade:

System age – Most HVAC units last 12–15 years with proper maintenance. Anything beyond that is on borrowed time.
Frequent breakdowns – If you’ve called us three or more times in the past two years, the costs add up quickly.
Rising energy bills despite maintenance – Indicates your system is losing efficiency.
Major component failure – If your compressor or heat exchanger fails, replacement is usually the smarter financial choice.

The 50% Rule: A Handy Guide

Here’s a rule of thumb we share with Boone-area homeowners:

If the cost of repair is less than 50% of the cost of a new system and your unit is under 10 years old, repair is usually the best choice.
If the repair cost is more than 50% of a new system’s cost or your unit is over 12 years old, replacement often provides better long-term value.
