Signs It's Time to Replace, Not Repair
- Your system is 12+ years old and needs a costly repair
- You’re calling for repairs more than once a year
- Your energy bills keep climbing despite regular maintenance
- Your home has uneven cooling — some rooms hot, some cold
- Your system still uses R-22 refrigerant (being phased out and increasingly expensive to service)
- A repair estimate is running 50% or more of the cost of a new system
If none of those apply, a repair may still be your best option. We’ll always give you an honest read on which makes more financial sense, not just push a sale.
What’s Included With a New Installation
Every installation from Diamond Air includes:
- A free in-home estimate and load calculation, so your new system is sized correctly for your home (not just a swap of the old unit)
- Certified installation by our in-house technicians — no subcontractors
- Removal and disposal of your old system
- A walkthrough of your new thermostat and system controls
- Manufacturer warranty registration handled for you
We install trusted, energy-efficient systems built for Texas heat, and can walk you through options at different price points and efficiency ratings so you’re choosing based on your home’s actual needs, not just the lowest sticker price.
