Repair or Replace? Know Before You Decide.
A clear framework to help you make the right call — based on your system's age, condition, and what the numbers actually say.
5 Questions to Ask Before Deciding
01
How old is your system?
Most HVAC systems last 15–20 years. If yours is under 10, a repair usually makes more sense. Over 15? Replacement starts to look better — especially with today's efficiency gains.
02
What's the repair cost vs. system value?
If a single repair costs more than 50% of a new system's price, replace it. Small repairs ($150–$500) on a younger system? Almost always worth fixing.
03
How's your energy bill trending?
A system that's losing efficiency shows up on your utility bill first. If your costs are climbing year over year with no change in usage, the system is working harder to do less.
04
Is this a repeat problem?
One breakdown is a bad day. Three breakdowns in two years is a pattern. Repeated repairs on the same component (compressor, blower motor, coil) signal it's time to move on.
05
Are you planning to stay in the home?
New HVAC adds resale value and is a selling point for buyers. If you're moving in a year or two, a cheap repair might be the pragmatic choice. Staying long-term? Invest in replacement.
